briefing 6 00:00:18,230 --> 00:00:18,240 we're holding this uh special briefing 7 00:00:18,240 --> 00:00:20,790 we're holding this uh special briefing today to discuss the largest fragment of 8 00:00:20,790 --> 00:00:20,800 today to discuss the largest fragment of 9 00:00:20,800 --> 00:00:22,710 today to discuss the largest fragment of comet shoemaker levy to strike jupiter 10 00:00:22,710 --> 00:00:22,720 comet shoemaker levy to strike jupiter 11 00:00:22,720 --> 00:00:23,910 comet shoemaker levy to strike jupiter so far 12 00:00:23,910 --> 00:00:23,920 so far 13 00:00:23,920 --> 00:00:26,150 so far that fragment fragment g 14 00:00:26,150 --> 00:00:26,160 that fragment fragment g 15 00:00:26,160 --> 00:00:27,830 that fragment fragment g struck the planet early this morning and 16 00:00:27,830 --> 00:00:27,840 struck the planet early this morning and 17 00:00:27,840 --> 00:00:30,070 struck the planet early this morning and has produced some pretty exciting uh 18

very exciting results 52 00:00:59,750 --> 00:00:59,760 results 53 00:00:59,760 --> 00:01:01,270 results thanks gene 54 00:01:01,270 --> 00:01:01,280 thanks gene 55 00:01:01,280 --> 00:01:05,109 thanks gene it was just 12 hours ago that g hit 56 00:01:05,109 --> 00:01:05,119 it was just 12 hours ago that g hit 57 00:01:05,119 --> 00:01:07,270 it was just 12 hours ago that g hit so we've been working very hard in the 58 00:01:07,270 --> 00:01:07,280 so we've been working very hard in the 59 00:01:07,280 --> 00:01:09,109 so we've been working very hard in the last half day to be to be able to bring 60 00:01:09,109 --> 00:01:09,119 last half day to be to be able to bring 61 00:01:09,119 --> 00:01:10,550 last half day to be to be able to bring you these images 62 00:01:10,550 --> 00:01:10,560 you these images 63 00:01:10,560 --> 00:01:12,550 you these images and i'm sure that in a few days we'll 64 00:01:12,550 --> 00:01:12,560 and i'm sure that in a few days we'll 65 00:01:12,560 --> 00:01:14,469 and i'm sure that in a few days we'll have a lot more to show you right now we 66 00:01:14,469 --> 00:01:14,479 have a lot more to show you right now we 67 00:01:14,479 --> 00:01:16,390 have a lot more to show you right now we just have black and white pictures no 68 00:01:16,390 --> 00:01:16,400 just have black and white pictures no 69 00:01:16,400 --> 00:01:18,630 just have black and white pictures no color just hang on 70 00:01:18,630 --> 00:01:18,640 color just hang on 71 00:01:18,640 --> 00:01:20,950 color just hang on so i'll just uh cut straight to it and 72 00:01:20,950 --> 00:01:20,960 so i'll just uh cut straight to it and 73 00:01:20,960 --> 00:01:23,510 so i'll just uh cut straight to it and show you some of the images we were 74 00:01:23,510 --> 00:01:23,520 show you some of the images we were 75 00:01:23,520 --> 00:01:25,910 show you some of the images we were lucky enough to be observing right when 76 00:01:25,910 --> 00:01:25,920 lucky enough to be observing right when 77 00:01:25,920 --> 00:01:27,510 lucky enough to be observing right when this thing happened 78 00:01:27,510 --> 00:01:27,520 this thing happened 79 00:01:27,520 --> 00:01:29,270 this thing happened we have one image before the sequence 80 00:01:29,270 --> 00:01:29,280 we have one image before the sequence 81 00:01:29,280 --> 00:01:31,429 we have one image before the sequence which shows nothing then you can see a 82 00:01:31,429 --> 00:01:31,439 which shows nothing then you can see a 83 00:01:31,439 --> 00:01:33,990 which shows nothing then you can see a tiny tip of the fireball 84 00:01:33,990 --> 00:01:34,000 tiny tip of the fireball 85 00:01:34,000 --> 00:01:36,069 tiny tip of the fireball and just a few minutes later five 86 00:01:36,069 --> 00:01:36,079 and just a few minutes later five 87 00:01:36,079 --> 00:01:39,590 and just a few minutes later five minutes later the the plume is growing 88 00:01:39,590 --> 00:01:39,600 minutes later the the plume is growing 89 00:01:39,600 --> 00:01:41,270 minutes later the the plume is growing three minutes later it's grown even 90 00:01:41,270 --> 00:01:41,280 three minutes later it's grown even 91 00:01:41,280 --> 00:01:42,390 three minutes later it's grown even larger 92 00:01:42,390 --> 00:01:42,400 larger 93 00:01:42,400 --> 00:01:44,230 larger three minutes after that it seems to 94 00:01:44,230 --> 00:01:44,240 three minutes after that it seems to 95 00:01:44,240 --> 00:01:46,870 three minutes after that it seems to have stabilized reached peak altitude 96 00:01:46,870 --> 00:01:46,880 have stabilized reached peak altitude 97 00:01:46,880 --> 00:01:49,429 have stabilized reached peak altitude but started to spread and then we have a 98 00:01:49,429 --> 00:01:49,439 but started to spread and then we have a 99 00:01:49,439 --> 00:01:51,670 but started to spread and then we have a seven minute gap and you can see that 100 00:01:51,670 --> 00:01:51,680 seven minute gap and you can see that 101 00:01:51,680 --> 00:01:53,510 seven minute gap and you can see that it's completely flattened out into that 102 00:01:53,510 --> 00:01:53,520 it's completely flattened out into that 103 00:01:53,520 --> 00:01:56,230 it's completely flattened out into that pancake again we have about 104 00:01:56,230 --> 00:01:56,240 pancake again we have about 105 00:01:56,240 --> 00:01:58,230 pancake again we have about three or four more images all showing 106 00:01:58,230 --> 00:01:58,240 three or four more images all showing 107 00:01:58,240 --> 00:02:01,590 three or four more images all showing that that flat pancake just hanging in 108 00:02:01,590 --> 00:02:01,600 that that flat pancake just hanging in 109 00:02:01,600 --> 00:02:03,990 that that flat pancake just hanging in there and then we start to see it rotate 110 00:02:03,990 --> 00:02:04,000 there and then we start to see it rotate 111 00:02:04,000 --> 00:02:05,830 there and then we start to see it rotate onto the disc 112 00:02:05,830 --> 00:02:05,840 onto the disc 113 00:02:05,840 --> 00:02:08,389 onto the disc we then an hour and a half later took a 114 00:02:08,389 --> 00:02:08,399 we then an hour and a half later took a 115 00:02:08,399 --> 00:02:11,190 we then an hour and a half later took a series of images with this impact site 116 00:02:11,190 --> 00:02:11,200 series of images with this impact site 117 00:02:11,200 --> 00:02:13,030 series of images with this impact site rotated onto the disk and i'd like to 118 00:02:13,030 --> 00:02:13,040 rotated onto the disk and i'd like to 119 00:02:13,040 --> 00:02:15,910 rotated onto the disk and i'd like to show you that particular view right now 120 00:02:15,910 --> 00:02:15,920 show you that particular view right now 121 00:02:15,920 --> 00:02:18,869 show you that particular view right now we were using the planetary camera and 122 00:02:18,869 --> 00:02:18,879 we were using the planetary camera and 123 00:02:18,879 --> 00:02:20,710 we were using the planetary camera and we can't fit the whole image of jupiter 124 00:02:20,710 --> 00:02:20,720 we can't fit the whole image of jupiter 125 00:02:20,720 --> 00:02:22,550 we can't fit the whole image of jupiter in the planetary camera because it's 126 00:02:22,550 --> 00:02:22,560 in the planetary camera because it's 127 00:02:22,560 --> 00:02:24,949 in the planetary camera because it's very high resolution camera you can 128 00:02:24,949 --> 00:02:24,959 very high resolution camera you can 129 00:02:24,959 --> 00:02:27,670 very high resolution camera you can clearly see the impact site 130 00:02:27,670 --> 00:02:27,680 clearly see the impact site 131 00:02:27,680 --> 00:02:28,630 clearly see the impact site now 132 00:02:28,630 --> 00:02:28,640 now 133 00:02:28,640 --> 00:02:30,390 now remember a few days ago i showed you a 134 00:02:30,390 --> 00:02:30,400 remember a few days ago i showed you a 135 00:02:30,400 --> 00:02:32,630 remember a few days ago i showed you a picture with a box and i said the box 136 00:02:32,630 --> 00:02:32,640 picture with a box and i said the box 137 00:02:32,640 --> 00:02:35,589 picture with a box and i said the box was the size two earth diameters let me 138 00:02:35,589 --> 00:02:35,599 was the size two earth diameters let me 139 00:02:35,599 --> 00:02:37,910 was the size two earth diameters let me give you a sense of scale here 140 00:02:37,910 --> 00:02:37,920 give you a sense of scale here 141 00:02:37,920 --> 00:02:40,630 give you a sense of scale here you can see a little bright ring and if 142 00:02:40,630 --> 00:02:40,640 you can see a little bright ring and if 143 00:02:40,640 --> 00:02:42,390 you can see a little bright ring and if you could keep the graphic up so people 144 00:02:42,390 --> 00:02:42,400 you could keep the graphic up so people 145 00:02:42,400 --> 00:02:45,110 you could keep the graphic up so people can see it at the other places 146 00:02:45,110 --> 00:02:45,120 can see it at the other places 147 00:02:45,120 --> 00:02:47,430 can see it at the other places there's a bright spot and there's a 148 00:02:47,430 --> 00:02:47,440 there's a bright spot and there's a 149 00:02:47,440 --> 00:02:49,589 there's a bright spot and there's a little dark ring you can see around the 150 00:02:49,589 --> 00:02:49,599 little dark ring you can see around the 151 00:02:49,599 --> 00:02:52,229 little dark ring you can see around the spot and then you see a larger sort of 152 00:02:52,229 --> 00:02:52,239 spot and then you see a larger sort of 153 00:02:52,239 --> 00:02:54,229 spot and then you see a larger sort of smudge to the south 154 00:02:54,229 --> 00:02:54,239 smudge to the south 155 00:02:54,239 --> 00:02:56,869 smudge to the south that little dark ring is 80 percent of 156 00:02:56,869 --> 00:02:56,879 that little dark ring is 80 percent of 157 00:02:56,879 --> 00:02:59,830 that little dark ring is 80 percent of the size of the earth 158 00:02:59,830 --> 00:02:59,840 the size of the earth 159 00:02:59,840 --> 00:03:02,550 the size of the earth that large ring that big smudge you 160 00:03:02,550 --> 00:03:02,560 that large ring that big smudge you 161 00:03:02,560 --> 00:03:05,990 that large ring that big smudge you could easily fit the earth inside that 162 00:03:05,990 --> 00:03:06,000 could easily fit the earth inside that 163 00:03:06,000 --> 00:03:07,589 could easily fit the earth inside that diameter 164 00:03:07,589 --> 00:03:07,599 diameter 165 00:03:07,599 --> 00:03:11,350 diameter this is one big impact site 166 00:03:11,350 --> 00:03:11,360 this is one big impact site 167 00:03:11,360 --> 00:03:13,350 this is one big impact site it looks a little oval because we're 168 00:03:13,350 --> 00:03:13,360 it looks a little oval because we're 169 00:03:13,360 --> 00:03:16,229 it looks a little oval because we're very far south and we're also close to 170 00:03:16,229 --> 00:03:16,239 very far south and we're also close to 171 00:03:16,239 --> 00:03:17,589 very far south and we're also close to the edge of jupiter so you have an 172 00:03:17,589 --> 00:03:17,599 the edge of jupiter so you have an 173 00:03:17,599 --> 00:03:19,589 the edge of jupiter so you have an interesting projection effect let me 174 00:03:19,589 --> 00:03:19,599 interesting projection effect let me 175 00:03:19,599 --> 00:03:21,830 interesting projection effect let me show you a blow up of that this is a 176 00:03:21,830 --> 00:03:21,840 show you a blow up of that this is a 177 00:03:21,840 --> 00:03:23,670 show you a blow up of that this is a blow up in the green wavelength and then 178 00:03:23,670 --> 00:03:23,680 blow up in the green wavelength and then 179 00:03:23,680 --> 00:03:25,430 blow up in the green wavelength and then you can see more clearly that ring i was 180 00:03:25,430 --> 00:03:25,440 you can see more clearly that ring i was 181 00:03:25,440 --> 00:03:28,470 you can see more clearly that ring i was talking about now when we project that 182 00:03:28,470 --> 00:03:28,480 talking about now when we project that 183 00:03:28,480 --> 00:03:30,390 talking about now when we project that out as to what it would look like if we 184 00:03:30,390 --> 00:03:30,400 out as to what it would look like if we 185 00:03:30,400 --> 00:03:31,750 out as to what it would look like if we were looking straight on that ring is 186 00:03:31,750 --> 00:03:31,760 were looking straight on that ring is 187 00:03:31,760 --> 00:03:33,830 were looking straight on that ring is perfectly circular 188 00:03:33,830 --> 00:03:33,840 perfectly circular 189 00:03:33,840 --> 00:03:36,309 perfectly circular and so is that larger white ring around 190 00:03:36,309 --> 00:03:36,319 and so is that larger white ring around 191 00:03:36,319 --> 00:03:37,750 and so is that larger white ring around it 192 00:03:37,750 --> 00:03:37,760 it 193 00:03:37,760 --> 00:03:39,830 it you see that little spot to the side 194 00:03:39,830 --> 00:03:39,840 you see that little spot to the side 195 00:03:39,840 --> 00:03:42,070 you see that little spot to the side that's the d impact site 196 00:03:42,070 --> 00:03:42,080 that's the d impact site 197 00:03:42,080 --> 00:03:43,830 that's the d impact site that went in a little a couple days 198 00:03:43,830 --> 00:03:43,840 that went in a little a couple days 199 00:03:43,840 --> 00:03:46,229 that went in a little a couple days earlier and so g just barely missed 200 00:03:46,229 --> 00:03:46,239 earlier and so g just barely missed 201 00:03:46,239 --> 00:03:48,229 earlier and so g just barely missed hitting d and i'll get back to that 202 00:03:48,229 --> 00:03:48,239 hitting d and i'll get back to that 203 00:03:48,239 --> 00:03:49,750 hitting d and i'll get back to that effect later on 204 00:03:49,750 --> 00:03:49,760 effect later on 205 00:03:49,760 --> 00:03:50,710 effect later on um 206 00:03:50,710 --> 00:03:50,720 um 207 00:03:50,720 --> 00:03:52,630 um what something very interesting that you 208 00:03:52,630 --> 00:03:52,640 what something very interesting that you 209 00:03:52,640 --> 00:03:54,229 what something very interesting that you might be able to see in these graphics 210 00:03:54,229 --> 00:03:54,239 might be able to see in these graphics 211 00:03:54,239 --> 00:03:55,190 might be able to see in these graphics is that 212 00:03:55,190 --> 00:03:55,200 is that 213 00:03:55,200 --> 00:03:57,110 is that as before there's sort of a streak 214 00:03:57,110 --> 00:03:57,120 as before there's sort of a streak 215 00:03:57,120 --> 00:03:59,110 as before there's sort of a streak there's the center of the ring and then 216 00:03:59,110 --> 00:03:59,120 there's the center of the ring and then 217 00:03:59,120 --> 00:04:01,670 there's the center of the ring and then a smudge off to the side very black sort 218 00:04:01,670 --> 00:04:01,680 a smudge off to the side very black sort 219 00:04:01,680 --> 00:04:04,070 a smudge off to the side very black sort of thing if you look very carefully now 220 00:04:04,070 --> 00:04:04,080 of thing if you look very carefully now 221 00:04:04,080 --> 00:04:06,710 of thing if you look very carefully now in that smudge around to the south 222 00:04:06,710 --> 00:04:06,720 in that smudge around to the south 223 00:04:06,720 --> 00:04:09,429 in that smudge around to the south you might see rays 224 00:04:09,429 --> 00:04:09,439 you might see rays 225 00:04:09,439 --> 00:04:11,110 you might see rays you see those rays 226 00:04:11,110 --> 00:04:11,120 you see those rays 227 00:04:11,120 --> 00:04:13,670 you see those rays okay if you look very carefully you will 228 00:04:13,670 --> 00:04:13,680 okay if you look very carefully you will 229 00:04:13,680 --> 00:04:16,629 okay if you look very carefully you will notice that those rays do not appear to 230 00:04:16,629 --> 00:04:16,639 notice that those rays do not appear to 231 00:04:16,639 --> 00:04:19,590 notice that those rays do not appear to point to the center of the ring 232 00:04:19,590 --> 00:04:19,600 point to the center of the ring 233 00:04:19,600 --> 00:04:21,830 point to the center of the ring they appear to a point they appear to 234 00:04:21,830 --> 00:04:21,840 they appear to a point they appear to 235 00:04:21,840 --> 00:04:24,390 they appear to a point they appear to point towards where that smudge 236 00:04:24,390 --> 00:04:24,400 point towards where that smudge 237 00:04:24,400 --> 00:04:26,710 point towards where that smudge intersects the ring 238 00:04:26,710 --> 00:04:26,720 intersects the ring 239 00:04:26,720 --> 00:04:29,110 intersects the ring that's very interesting 240 00:04:29,110 --> 00:04:29,120 that's very interesting 241 00:04:29,120 --> 00:04:30,790 that's very interesting let's show the next image this is a 242 00:04:30,790 --> 00:04:30,800 let's show the next image this is a 243 00:04:30,800 --> 00:04:33,110 let's show the next image this is a green image the following image you see 244 00:04:33,110 --> 00:04:33,120 green image the following image you see 245 00:04:33,120 --> 00:04:35,270 green image the following image you see is the methane band image which i've 246 00:04:35,270 --> 00:04:35,280 is the methane band image which i've 247 00:04:35,280 --> 00:04:37,189 is the methane band image which i've shown you before remember i talked about 248 00:04:37,189 --> 00:04:37,199 shown you before remember i talked about 249 00:04:37,199 --> 00:04:39,430 shown you before remember i talked about green visual wavelengths it's dark in 250 00:04:39,430 --> 00:04:39,440 green visual wavelengths it's dark in 251 00:04:39,440 --> 00:04:41,350 green visual wavelengths it's dark in the methane band image it's bright and 252 00:04:41,350 --> 00:04:41,360 the methane band image it's bright and 253 00:04:41,360 --> 00:04:43,350 the methane band image it's bright and there you can see this even more clearly 254 00:04:43,350 --> 00:04:43,360 there you can see this even more clearly 255 00:04:43,360 --> 00:04:45,030 there you can see this even more clearly you see those rays that are emanating 256 00:04:45,030 --> 00:04:45,040 you see those rays that are emanating 257 00:04:45,040 --> 00:04:47,189 you see those rays that are emanating from that intersection of the bright 258 00:04:47,189 --> 00:04:47,199 from that intersection of the bright 259 00:04:47,199 --> 00:04:49,909 from that intersection of the bright ring and that central streak 260 00:04:49,909 --> 00:04:49,919 ring and that central streak 261 00:04:49,919 --> 00:04:52,710 ring and that central streak we don't know quite what this means yet 262 00:04:52,710 --> 00:04:52,720 we don't know quite what this means yet 263 00:04:52,720 --> 00:04:55,909 we don't know quite what this means yet but but i have a theory and and i'm sure 264 00:04:55,909 --> 00:04:55,919 but but i have a theory and and i'm sure 265 00:04:55,919 --> 00:04:57,430 but but i have a theory and and i'm sure everybody has theories but since i'm 266 00:04:57,430 --> 00:04:57,440 everybody has theories but since i'm 267 00:04:57,440 --> 00:04:58,790 everybody has theories but since i'm here in front of you i'll tell you my 268 00:04:58,790 --> 00:04:58,800 here in front of you i'll tell you my 269 00:04:58,800 --> 00:05:00,870 here in front of you i'll tell you my theory and then gene can tell you his 270 00:05:00,870 --> 00:05:00,880 theory and then gene can tell you his 271 00:05:00,880 --> 00:05:04,790 theory and then gene can tell you his theory uh my theory is this that the the 272 00:05:04,790 --> 00:05:04,800 theory uh my theory is this that the the 273 00:05:04,800 --> 00:05:08,390 theory uh my theory is this that the the lower southern portion of that streak 274 00:05:08,390 --> 00:05:08,400 lower southern portion of that streak 275 00:05:08,400 --> 00:05:10,790 lower southern portion of that streak is the impact site itself 276 00:05:10,790 --> 00:05:10,800 is the impact site itself 277 00:05:10,800 --> 00:05:12,710 is the impact site itself and that what happens is this thing 278 00:05:12,710 --> 00:05:12,720 and that what happens is this thing 279 00:05:12,720 --> 00:05:15,189 and that what happens is this thing streaks in there keep the graphic up so 280 00:05:15,189 --> 00:05:15,199 streaks in there keep the graphic up so 281 00:05:15,199 --> 00:05:16,870 streaks in there keep the graphic up so people can visualize what i'm saying 282 00:05:16,870 --> 00:05:16,880 people can visualize what i'm saying 283 00:05:16,880 --> 00:05:19,110 people can visualize what i'm saying here either either color 284 00:05:19,110 --> 00:05:19,120 here either either color 285 00:05:19,120 --> 00:05:21,510 here either either color it's it goes into the lower part and 286 00:05:21,510 --> 00:05:21,520 it's it goes into the lower part and 287 00:05:21,520 --> 00:05:23,909 it's it goes into the lower part and streaks down into the atmosphere and at 288 00:05:23,909 --> 00:05:23,919 streaks down into the atmosphere and at 289 00:05:23,919 --> 00:05:27,110 streaks down into the atmosphere and at some point it explodes and that cir that 290 00:05:27,110 --> 00:05:27,120 some point it explodes and that cir that 291 00:05:27,120 --> 00:05:29,270 some point it explodes and that cir that bright circular ring is centered on the 292 00:05:29,270 --> 00:05:29,280 bright circular ring is centered on the 293 00:05:29,280 --> 00:05:30,870 bright circular ring is centered on the impact site 294 00:05:30,870 --> 00:05:30,880 impact site 295 00:05:30,880 --> 00:05:33,270 impact site right then the fireball 296 00:05:33,270 --> 00:05:33,280 right then the fireball 297 00:05:33,280 --> 00:05:34,150 right then the fireball comes 298 00:05:34,150 --> 00:05:34,160 comes 299 00:05:34,160 --> 00:05:35,990 comes portions of the fireball move back out 300 00:05:35,990 --> 00:05:36,000 portions of the fireball move back out 301 00:05:36,000 --> 00:05:38,550 portions of the fireball move back out the impact site and spew out when they 302 00:05:38,550 --> 00:05:38,560 the impact site and spew out when they 303 00:05:38,560 --> 00:05:41,029 the impact site and spew out when they get to the to the top to the hole and 304 00:05:41,029 --> 00:05:41,039 get to the to the top to the hole and 305 00:05:41,039 --> 00:05:42,950 get to the to the top to the hole and that's why those rays are centered on 306 00:05:42,950 --> 00:05:42,960 that's why those rays are centered on 307 00:05:42,960 --> 00:05:45,670 that's why those rays are centered on the end and not on the center of the 308 00:05:45,670 --> 00:05:45,680 the end and not on the center of the 309 00:05:45,680 --> 00:05:46,710 the end and not on the center of the ring 310 00:05:46,710 --> 00:05:46,720 ring 311 00:05:46,720 --> 00:05:49,029 ring now remind you this is just my theory 312 00:05:49,029 --> 00:05:49,039 now remind you this is just my theory 313 00:05:49,039 --> 00:05:51,350 now remind you this is just my theory and i'm not a theorist i'm an 314 00:05:51,350 --> 00:05:51,360 and i'm not a theorist i'm an 315 00:05:51,360 --> 00:05:53,110 and i'm not a theorist i'm an observational astronomer but that's what 316 00:05:53,110 --> 00:05:53,120 observational astronomer but that's what 317 00:05:53,120 --> 00:05:55,590 observational astronomer but that's what the observations sure look like to me 318 00:05:55,590 --> 00:05:55,600 the observations sure look like to me 319 00:05:55,600 --> 00:05:57,189 the observations sure look like to me now the question is why is that whole 320 00:05:57,189 --> 00:05:57,199 now the question is why is that whole 321 00:05:57,199 --> 00:05:59,110 now the question is why is that whole streak bright 322 00:05:59,110 --> 00:05:59,120 streak bright 323 00:05:59,120 --> 00:06:00,870 streak bright and that could very well be that that 324 00:06:00,870 --> 00:06:00,880 and that could very well be that that 325 00:06:00,880 --> 00:06:03,670 and that could very well be that that whole tube is just very very very hot 326 00:06:03,670 --> 00:06:03,680 whole tube is just very very very hot 327 00:06:03,680 --> 00:06:05,350 whole tube is just very very very hot and it's ionized and 328 00:06:05,350 --> 00:06:05,360 and it's ionized and 329 00:06:05,360 --> 00:06:07,270 and it's ionized and and gene might tell you later that that 330 00:06:07,270 --> 00:06:07,280 and gene might tell you later that that 331 00:06:07,280 --> 00:06:09,430 and gene might tell you later that that all of it's rising but that some of it 332 00:06:09,430 --> 00:06:09,440 all of it's rising but that some of it 333 00:06:09,440 --> 00:06:11,430 all of it's rising but that some of it spews out the end there 334 00:06:11,430 --> 00:06:11,440 spews out the end there 335 00:06:11,440 --> 00:06:13,909 spews out the end there so so that's my that's my personal 336 00:06:13,909 --> 00:06:13,919 so so that's my that's my personal 337 00:06:13,919 --> 00:06:16,150 so so that's my that's my personal theory about what that image shows but 338 00:06:16,150 --> 00:06:16,160 theory about what that image shows but 339 00:06:16,160 --> 00:06:18,230 theory about what that image shows but we're going to have to do a lot of work 340 00:06:18,230 --> 00:06:18,240 we're going to have to do a lot of work 341 00:06:18,240 --> 00:06:19,990 we're going to have to do a lot of work before we can say for sure that's what's 342 00:06:19,990 --> 00:06:20,000 before we can say for sure that's what's 343 00:06:20,000 --> 00:06:21,590 before we can say for sure that's what's really happening 344 00:06:21,590 --> 00:06:21,600 really happening 345 00:06:21,600 --> 00:06:24,150 really happening um 346 00:06:24,150 --> 00:06:24,160 347 00:06:24,160 --> 00:06:25,590 the 348 00:06:25,590 --> 00:06:25,600 the 349 00:06:25,600 --> 00:06:27,670 the the energy of this event 350 00:06:27,670 --> 00:06:27,680 the energy of this event 351 00:06:27,680 --> 00:06:30,230 the energy of this event was probably about 25 times larger than 352 00:06:30,230 --> 00:06:30,240 was probably about 25 times larger than 353 00:06:30,240 --> 00:06:33,029 was probably about 25 times larger than that first impact we showed you and that 354 00:06:33,029 --> 00:06:33,039 that first impact we showed you and that 355 00:06:33,039 --> 00:06:35,350 that first impact we showed you and that jives very well with the sizes of these 356 00:06:35,350 --> 00:06:35,360 jives very well with the sizes of these 357 00:06:35,360 --> 00:06:38,390 jives very well with the sizes of these things this is a much larger splotch on 358 00:06:38,390 --> 00:06:38,400 things this is a much larger splotch on 359 00:06:38,400 --> 00:06:39,510 things this is a much larger splotch on jupiter 360 00:06:39,510 --> 00:06:39,520 jupiter 361 00:06:39,520 --> 00:06:41,830 jupiter and very likely this splotch will be 362 00:06:41,830 --> 00:06:41,840 and very likely this splotch will be 363 00:06:41,840 --> 00:06:44,550 and very likely this splotch will be spreading out as the days go by one 364 00:06:44,550 --> 00:06:44,560 spreading out as the days go by one 365 00:06:44,560 --> 00:06:45,909 spreading out as the days go by one interesting thing that i don't have a 366 00:06:45,909 --> 00:06:45,919 interesting thing that i don't have a 367 00:06:45,919 --> 00:06:47,430 interesting thing that i don't have a graphic to show you but i'll share with 368 00:06:47,430 --> 00:06:47,440 graphic to show you but i'll share with 369 00:06:47,440 --> 00:06:49,909 graphic to show you but i'll share with you is in one of our wavelengths 370 00:06:49,909 --> 00:06:49,919 you is in one of our wavelengths 371 00:06:49,919 --> 00:06:52,390 you is in one of our wavelengths we can tell that this material is very 372 00:06:52,390 --> 00:06:52,400 we can tell that this material is very 373 00:06:52,400 --> 00:06:55,110 we can tell that this material is very very thin this big that big brown smudge 374 00:06:55,110 --> 00:06:55,120 very thin this big that big brown smudge 375 00:06:55,120 --> 00:06:57,830 very thin this big that big brown smudge the the black eye on jupiter as it were 376 00:06:57,830 --> 00:06:57,840 the the black eye on jupiter as it were 377 00:06:57,840 --> 00:07:00,150 the the black eye on jupiter as it were that smudge is very thin because we can 378 00:07:00,150 --> 00:07:00,160 that smudge is very thin because we can 379 00:07:00,160 --> 00:07:02,070 that smudge is very thin because we can see the bands of jupiter right through 380 00:07:02,070 --> 00:07:02,080 see the bands of jupiter right through 381 00:07:02,080 --> 00:07:02,950 see the bands of jupiter right through it 382 00:07:02,950 --> 00:07:02,960 it 383 00:07:02,960 --> 00:07:06,390 it it's just laying right over top of that 384 00:07:06,390 --> 00:07:06,400 it's just laying right over top of that 385 00:07:06,400 --> 00:07:07,350 it's just laying right over top of that so 386 00:07:07,350 --> 00:07:07,360 so 387 00:07:07,360 --> 00:07:09,189 so i think that's about all i have to say 388 00:07:09,189 --> 00:07:09,199 i think that's about all i have to say 389 00:07:09,199 --> 00:07:11,189 i think that's about all i have to say right now we're going to be working very 390 00:07:11,189 --> 00:07:11,199 right now we're going to be working very 391 00:07:11,199 --> 00:07:13,510 right now we're going to be working very hard over the next few days to analyze 392 00:07:13,510 --> 00:07:13,520 hard over the next few days to analyze 393 00:07:13,520 --> 00:07:16,710 hard over the next few days to analyze these data and i should add that we are 394 00:07:16,710 --> 00:07:16,720 these data and i should add that we are 395 00:07:16,720 --> 00:07:18,870 these data and i should add that we are not the only observatory in the world 396 00:07:18,870 --> 00:07:18,880 not the only observatory in the world 397 00:07:18,880 --> 00:07:21,029 not the only observatory in the world watching this many observatories around 398 00:07:21,029 --> 00:07:21,039 watching this many observatories around 399 00:07:21,039 --> 00:07:23,589 watching this many observatories around the country have been focused on this 400 00:07:23,589 --> 00:07:23,599 the country have been focused on this 401 00:07:23,599 --> 00:07:25,670 the country have been focused on this and are reporting very exciting results 402 00:07:25,670 --> 00:07:25,680 and are reporting very exciting results 403 00:07:25,680 --> 00:07:27,510 and are reporting very exciting results in the infrared they've been studying 404 00:07:27,510 --> 00:07:27,520 in the infrared they've been studying 405 00:07:27,520 --> 00:07:29,430 in the infrared they've been studying that plume in the infrared they're 406 00:07:29,430 --> 00:07:29,440 that plume in the infrared they're 407 00:07:29,440 --> 00:07:32,390 that plume in the infrared they're seeing the spot in the infrared 408 00:07:32,390 --> 00:07:32,400 seeing the spot in the infrared 409 00:07:32,400 --> 00:07:34,070 seeing the spot in the infrared all over the world people are tracking 410 00:07:34,070 --> 00:07:34,080 all over the world people are tracking 411 00:07:34,080 --> 00:07:35,749 all over the world people are tracking this 412 00:07:35,749 --> 00:07:35,759 this 413 00:07:35,759 --> 00:07:37,510 this okay thanks heidi 414 00:07:37,510 --> 00:07:37,520 okay thanks heidi 415 00:07:37,520 --> 00:07:39,990 okay thanks heidi uh i wonder if you want to mention 416 00:07:39,990 --> 00:07:40,000 uh i wonder if you want to mention 417 00:07:40,000 --> 00:07:42,070 uh i wonder if you want to mention uh the actual height the maximum height 418 00:07:42,070 --> 00:07:42,080 uh the actual height the maximum height 419 00:07:42,080 --> 00:07:43,749 uh the actual height the maximum height that we see above the limb there i don't 420 00:07:43,749 --> 00:07:43,759 that we see above the limb there i don't 421 00:07:43,759 --> 00:07:45,270 that we see above the limb there i don't think you may that's a good thing to 422 00:07:45,270 --> 00:07:45,280 think you may that's a good thing to 423 00:07:45,280 --> 00:07:47,830 think you may that's a good thing to mention um in that plume when we saw 424 00:07:47,830 --> 00:07:47,840 mention um in that plume when we saw 425 00:07:47,840 --> 00:07:50,309 mention um in that plume when we saw where it peaked out at some level 426 00:07:50,309 --> 00:07:50,319 where it peaked out at some level 427 00:07:50,319 --> 00:07:52,790 where it peaked out at some level that we looks like we are seeing that 428 00:07:52,790 --> 00:07:52,800 that we looks like we are seeing that 429 00:07:52,800 --> 00:07:56,869 that we looks like we are seeing that about 2 200 kilometers above the limb of 430 00:07:56,869 --> 00:07:56,879 about 2 200 kilometers above the limb of 431 00:07:56,879 --> 00:07:59,189 about 2 200 kilometers above the limb of jupiter and i'll remind you that the 432 00:07:59,189 --> 00:07:59,199 jupiter and i'll remind you that the 433 00:07:59,199 --> 00:08:01,909 jupiter and i'll remind you that the impact sequence we showed a few whenever 434 00:08:01,909 --> 00:08:01,919 impact sequence we showed a few whenever 435 00:08:01,919 --> 00:08:05,189 impact sequence we showed a few whenever it was yesterday um there you go that 436 00:08:05,189 --> 00:08:05,199 it was yesterday um there you go that 437 00:08:05,199 --> 00:08:06,150 it was yesterday um there you go that only 438 00:08:06,150 --> 00:08:06,160 only 439 00:08:06,160 --> 00:08:08,070 only got about a little over a thousand 440 00:08:08,070 --> 00:08:08,080 got about a little over a thousand 441 00:08:08,080 --> 00:08:10,830 got about a little over a thousand kilometers so this is a factor of two 442 00:08:10,830 --> 00:08:10,840 kilometers so this is a factor of two 443 00:08:10,840 --> 00:08:13,510 kilometers so this is a factor of two higher okay great 444 00:08:13,510 --> 00:08:13,520 higher okay great 445 00:08:13,520 --> 00:08:16,790 higher okay great uh i'd like to make a uh 446 00:08:16,790 --> 00:08:16,800 uh i'd like to make a uh 447 00:08:16,800 --> 00:08:19,110 uh i'd like to make a uh heidi mentioned the energies 448 00:08:19,110 --> 00:08:19,120 heidi mentioned the energies 449 00:08:19,120 --> 00:08:21,430 heidi mentioned the energies and we sort of had a top of the 450 00:08:21,430 --> 00:08:21,440 and we sort of had a top of the 451 00:08:21,440 --> 00:08:23,670 and we sort of had a top of the head estimate of the energy this morning 452 00:08:23,670 --> 00:08:23,680 head estimate of the energy this morning 453 00:08:23,680 --> 00:08:25,189 head estimate of the energy this morning which i hadn't had a chance to actually 454 00:08:25,189 --> 00:08:25,199 which i hadn't had a chance to actually 455 00:08:25,199 --> 00:08:26,629 which i hadn't had a chance to actually calculate out i like to make a 456 00:08:26,629 --> 00:08:26,639 calculate out i like to make a 457 00:08:26,639 --> 00:08:29,189 calculate out i like to make a correction for everybody 458 00:08:29,189 --> 00:08:29,199 correction for everybody 459 00:08:29,199 --> 00:08:31,749 correction for everybody because we were multiplying by the wrong 460 00:08:31,749 --> 00:08:31,759 because we were multiplying by the wrong 461 00:08:31,759 --> 00:08:33,430 because we were multiplying by the wrong number to begin with it doesn't change 462 00:08:33,430 --> 00:08:33,440 number to begin with it doesn't change 463 00:08:33,440 --> 00:08:35,509 number to begin with it doesn't change our estimates of the sizes of the 464 00:08:35,509 --> 00:08:35,519 our estimates of the sizes of the 465 00:08:35,519 --> 00:08:36,870 our estimates of the sizes of the objects 466 00:08:36,870 --> 00:08:36,880 objects 467 00:08:36,880 --> 00:08:40,149 objects or the energy in ergs but it is a change 468 00:08:40,149 --> 00:08:40,159 or the energy in ergs but it is a change 469 00:08:40,159 --> 00:08:42,790 or the energy in ergs but it is a change if you want to put it into megatons so 470 00:08:42,790 --> 00:08:42,800 if you want to put it into megatons so 471 00:08:42,800 --> 00:08:44,550 if you want to put it into megatons so our best estimate or my best estimate 472 00:08:44,550 --> 00:08:44,560 our best estimate or my best estimate 473 00:08:44,560 --> 00:08:46,870 our best estimate or my best estimate for the energy for g 474 00:08:46,870 --> 00:08:46,880 for the energy for g 475 00:08:46,880 --> 00:08:49,829 for the energy for g uh is not the 250 million megatons we 476 00:08:49,829 --> 00:08:49,839 uh is not the 250 million megatons we 477 00:08:49,839 --> 00:08:52,230 uh is not the 250 million megatons we mentioned this morning but it's six 478 00:08:52,230 --> 00:08:52,240 mentioned this morning but it's six 479 00:08:52,240 --> 00:08:53,670 mentioned this morning but it's six 6 million 480 00:08:53,670 --> 00:08:53,680 6 million 481 00:08:53,680 --> 00:08:56,470 6 million megatons that's still a lot of megatons 482 00:08:56,470 --> 00:08:56,480 megatons that's still a lot of megatons 483 00:08:56,480 --> 00:08:58,470 megatons that's still a lot of megatons but please make that correction and 484 00:08:58,470 --> 00:08:58,480 but please make that correction and 485 00:08:58,480 --> 00:09:00,230 but please make that correction and correspondingly for 486

should be about 489 00:09:02,800 --> 00:09:06,870 for a the real number should be about 225 000 megatons that's still a lot of 490 00:09:06,870 --> 00:09:06,880 225 000 megatons that's still a lot of 491 00:09:06,880 --> 00:09:09,750 225 000 megatons that's still a lot of megatons uh but those uh that's just 492 00:09:09,750 --> 00:09:09,760 megatons uh but those uh that's just 493 00:09:09,760 --> 00:09:12,630 megatons uh but those uh that's just just a slip uh in in the ballpark 494 00:09:12,630 --> 00:09:12,640 just a slip uh in in the ballpark 495 00:09:12,640 --> 00:09:14,630 just a slip uh in in the ballpark estimate i made earlier so please 496 00:09:14,630 --> 00:09:14,640 estimate i made earlier so please 497 00:09:14,640 --> 00:09:15,590 estimate i made earlier so please

talk about that's even 527 00:09:44,320 --> 00:09:46,790 that i want to talk about that's even more exciting and that is some of you 528 00:09:46,790 --> 00:09:46,800 more exciting and that is some of you 529 00:09:46,800 --> 00:09:49,430 more exciting and that is some of you have heard about the q impact q used to 530 00:09:49,430 --> 00:09:49,440 have heard about the q impact q used to 531 00:09:49,440 --> 00:09:52,790 have heard about the q impact q used to be the brightest one before g took over 532 00:09:52,790 --> 00:09:52,800 be the brightest one before g took over 533 00:09:52,800 --> 00:09:54,230 be the brightest one before g took over and for a lot when we were doing our 534 00:09:54,230 --> 00:09:54,240 and for a lot when we were doing our 535 00:09:54,240 --> 00:09:55,990 and for a lot when we were doing our planning sequences early on we were 536 00:09:55,990 --> 00:09:56,000 planning sequences early on we were 537 00:09:56,000 --> 00:09:58,470 planning sequences early on we were planning on q as our primary target not 538 00:09:58,470 --> 00:09:58,480 planning on q as our primary target not 539 00:09:58,480 --> 00:09:59,430 planning on q as our primary target not g 540 00:09:59,430 --> 00:09:59,440 g 541 00:09:59,440 --> 00:10:00,389 g well 542 00:10:00,389 --> 00:10:00,399 well 543 00:10:00,399 --> 00:10:02,470 well when q goes in and i don't remember the 544 00:10:02,470 --> 00:10:02,480 when q goes in and i don't remember the 545 00:10:02,480 --> 00:10:04,790 when q goes in and i don't remember the time the date some sometime tomorrow or 546 00:10:04,790 --> 00:10:04,800 time the date some sometime tomorrow or 547 00:10:04,800 --> 00:10:06,230 time the date some sometime tomorrow or the next day 548 00:10:06,230 --> 00:10:06,240 the next day 549 00:10:06,240 --> 00:10:07,590 the next day a very interesting thing is going to 550 00:10:07,590 --> 00:10:07,600 a very interesting thing is going to 551 00:10:07,600 --> 00:10:08,710 a very interesting thing is going to happen 552 00:10:08,710 --> 00:10:08,720 happen 553 00:10:08,720 --> 00:10:11,829 happen q is going to go in and exactly one 554 00:10:11,829 --> 00:10:11,839 q is going to go in and exactly one 555 00:10:11,839 --> 00:10:15,110 q is going to go in and exactly one jovian rotation later 10 hours 556 00:10:15,110 --> 00:10:15,120 jovian rotation later 10 hours 557 00:10:15,120 --> 00:10:18,150 jovian rotation later 10 hours r is going to hit right next to the very 558 00:10:18,150 --> 00:10:18,160 r is going to hit right next to the very 559 00:10:18,160 --> 00:10:21,269 r is going to hit right next to the very same longitude as q 560 00:10:21,269 --> 00:10:21,279 same longitude as q 561 00:10:21,279 --> 00:10:24,710 same longitude as q and one jovian rotation after that s is 562 00:10:24,710 --> 00:10:24,720 and one jovian rotation after that s is 563 00:10:24,720 --> 00:10:26,949 and one jovian rotation after that s is going to hit the same longitude on 564 00:10:26,949 --> 00:10:26,959 going to hit the same longitude on 565 00:10:26,959 --> 00:10:27,990 going to hit the same longitude on jupiter 566 00:10:27,990 --> 00:10:28,000 jupiter 567 00:10:28,000 --> 00:10:30,710 jupiter so you're going to have three boom boom 568 00:10:30,710 --> 00:10:30,720 so you're going to have three boom boom 569 00:10:30,720 --> 00:10:32,389 so you're going to have three boom boom boom right on the very 570 00:10:32,389 --> 00:10:32,399 boom right on the very 571 00:10:32,399 --> 00:10:34,949 boom right on the very very small range of longitude 572 00:10:34,949 --> 00:10:34,959 very small range of longitude 573 00:10:34,959 --> 00:10:36,630 very small range of longitude and that is going to make one heck of a 574 00:10:36,630 --> 00:10:36,640 and that is going to make one heck of a 575 00:10:36,640 --> 00:10:38,630 and that is going to make one heck of a mess 576 00:10:38,630 --> 00:10:38,640 mess 577 00:10:38,640 --> 00:10:40,150 mess well we're really looking forward to 578 00:10:40,150 --> 00:10:40,160 well we're really looking forward to 579 00:10:40,160 --> 00:10:42,310 well we're really looking forward to that that's the um 580 00:10:42,310 --> 00:10:42,320 that that's the um 581 00:10:42,320 --> 00:10:44,310 that that's the um well not messes but we're looking 582 00:10:44,310 --> 00:10:44,320 well not messes but we're looking 583 00:10:44,320 --> 00:10:45,990 well not messes but we're looking forward to some really interesting 584 00:10:45,990 --> 00:10:46,000 forward to some really interesting 585 00:10:46,000 --> 00:10:48,069 forward to some really interesting chemistry because what that means is you 586 00:10:48,069 --> 00:10:48,079 chemistry because what that means is you 587 00:10:48,079 --> 00:10:49,110 chemistry because what that means is you know you're not just taking the 588 00:10:49,110 --> 00:10:49,120 know you're not just taking the 589 00:10:49,120 --> 00:10:50,470 know you're not just taking the atmosphere and stirring it up a little 590 00:10:50,470 --> 00:10:50,480 atmosphere and stirring it up a little 591 00:10:50,480 --> 00:10:52,790 atmosphere and stirring it up a little bit you're really stirring the 592 00:10:52,790 --> 00:10:52,800 bit you're really stirring the 593 00:10:52,800 --> 00:10:55,750 bit you're really stirring the atmosphere up a lot so that that'll be 594 00:10:55,750 --> 00:10:55,760 atmosphere up a lot so that that'll be 595 00:10:55,760 --> 00:10:57,670 atmosphere up a lot so that that'll be very interesting and that's that's why i 596 00:10:57,670 --> 00:10:57,680 very interesting and that's that's why i 597 00:10:57,680 --> 00:10:59,430 very interesting and that's that's why i mentioned those the proximity of those 598 00:10:59,430 --> 00:10:59,440 mentioned those the proximity of those 599 00:10:59,440 --> 00:11:01,350 mentioned those the proximity of those two impact sites 600 00:11:01,350 --> 00:11:01,360 two impact sites 601 00:11:01,360 --> 00:11:03,110 two impact sites bill 602 00:11:03,110 --> 00:11:03,120 bill 603 00:11:03,120 --> 00:11:05,110 bill uh bill hart with cbs for two quick was 604 00:11:05,110 --> 00:11:05,120 uh bill hart with cbs for two quick was 605 00:11:05,120 --> 00:11:07,590 uh bill hart with cbs for two quick was one the the very clearly defined ring 606 00:11:07,590 --> 00:11:07,600 one the the very clearly defined ring 607 00:11:07,600 --> 00:11:11,430 one the the very clearly defined ring around the central thing 608 00:11:11,430 --> 00:11:11,440 around the central thing 609 00:11:11,440 --> 00:11:13,190 around the central thing great question awfully sharply defined 610 00:11:13,190 --> 00:11:13,200 great question awfully sharply defined 611 00:11:13,200 --> 00:11:15,430 great question awfully sharply defined and the other one is if you can see the 612 00:11:15,430 --> 00:11:15,440 and the other one is if you can see the 613 00:11:15,440 --> 00:11:17,509 and the other one is if you can see the cloud bands below the smudge you're 614 00:11:17,509 --> 00:11:17,519 cloud bands below the smudge you're 615 00:11:17,519 --> 00:11:19,190 cloud bands below the smudge you're seeing through it i suppose 616 00:11:19,190 --> 00:11:19,200 seeing through it i suppose 617 00:11:19,200 --> 00:11:21,350 seeing through it i suppose is there no wind at all at the altitude 618 00:11:21,350 --> 00:11:21,360 is there no wind at all at the altitude 619 00:11:21,360 --> 00:11:22,949 is there no wind at all at the altitude these things are would you expect that 620 00:11:22,949 --> 00:11:22,959 these things are would you expect that 621 00:11:22,959 --> 00:11:24,470 these things are would you expect that to change pretty rapidly if it's that 622 00:11:24,470 --> 00:11:24,480 to change pretty rapidly if it's that 623 00:11:24,480 --> 00:11:25,430 to change pretty rapidly if it's that thin 624 00:11:25,430 --> 00:11:25,440 thin 625 00:11:25,440 --> 00:11:28,389 thin all right great question that ring 626 00:11:28,389 --> 00:11:28,399 all right great question that ring 627 00:11:28,399 --> 00:11:30,790 all right great question that ring there are some theorists who would love 628 00:11:30,790 --> 00:11:30,800 there are some theorists who would love 629 00:11:30,800 --> 00:11:32,470 there are some theorists who would love to believe that that ring is an 630 00:11:32,470 --> 00:11:32,480 to believe that that ring is an 631 00:11:32,480 --> 00:11:34,389 to believe that that ring is an atmospheric wave 632 00:11:34,389 --> 00:11:34,399 atmospheric wave 633 00:11:34,399 --> 00:11:36,150 atmospheric wave it's too small to be a seismic wave but 634 00:11:36,150 --> 00:11:36,160 it's too small to be a seismic wave but 635 00:11:36,160 --> 00:11:37,590 it's too small to be a seismic wave but it could be one of these atmospheric 636 00:11:37,590 --> 00:11:37,600 it could be one of these atmospheric 637 00:11:37,600 --> 00:11:39,829 it could be one of these atmospheric waves that many theorists have been been 638 00:11:39,829 --> 00:11:39,839 waves that many theorists have been been 639 00:11:39,839 --> 00:11:41,590 waves that many theorists have been been predicting andy ingersoll and tim 640 00:11:41,590 --> 00:11:41,600 predicting andy ingersoll and tim 641 00:11:41,600 --> 00:11:43,990 predicting andy ingersoll and tim dowling and joe harrington 642 00:11:43,990 --> 00:11:44,000 dowling and joe harrington 643 00:11:44,000 --> 00:11:46,790 dowling and joe harrington they would love to believe that now 644 00:11:46,790 --> 00:11:46,800 they would love to believe that now 645 00:11:46,800 --> 00:11:49,910 they would love to believe that now if that ring expands then we'll believe 646 00:11:49,910 --> 00:11:49,920 if that ring expands then we'll believe 647 00:11:49,920 --> 00:11:52,870 if that ring expands then we'll believe it's a wave if that ring does not expand 648 00:11:52,870 --> 00:11:52,880 it's a wave if that ring does not expand 649 00:11:52,880 --> 00:11:55,190 it's a wave if that ring does not expand with time i'm talking about if it does 650 00:11:55,190 --> 00:11:55,200 with time i'm talking about if it does 651 00:11:55,200 --> 00:11:57,670 with time i'm talking about if it does not expand with time then we have to go 652 00:11:57,670 --> 00:11:57,680 not expand with time then we have to go 653 00:11:57,680 --> 00:11:59,509 not expand with time then we have to go back to the drawing board 654 00:11:59,509 --> 00:11:59,519 back to the drawing board 655 00:11:59,519 --> 00:12:01,350 back to the drawing board we're waiting to get the next sequence 656 00:12:01,350 --> 00:12:01,360 we're waiting to get the next sequence 657 00:12:01,360 --> 00:12:03,350 we're waiting to get the next sequence of images down so that we see what 658 00:12:03,350 --> 00:12:03,360 of images down so that we see what 659 00:12:03,360 --> 00:12:05,110 of images down so that we see what happens to that ring 660 00:12:05,110 --> 00:12:05,120 happens to that ring 661 00:12:05,120 --> 00:12:07,990 happens to that ring so it may be a wave it may not time will 662 00:12:07,990 --> 00:12:08,000 so it may be a wave it may not time will 663 00:12:08,000 --> 00:12:08,870 so it may be a wave it may not time will tell 664 00:12:08,870 --> 00:12:08,880 tell 665 00:12:08,880 --> 00:12:11,350 tell the other question was about the wind 666 00:12:11,350 --> 00:12:11,360 the other question was about the wind 667 00:12:11,360 --> 00:12:13,670 the other question was about the wind speed this image was only taken an hour 668 00:12:13,670 --> 00:12:13,680 speed this image was only taken an hour 669 00:12:13,680 --> 00:12:15,829 speed this image was only taken an hour and a half after the impact so in an 670 00:12:15,829 --> 00:12:15,839 and a half after the impact so in an 671 00:12:15,839 --> 00:12:17,509 and a half after the impact so in an hour and a half the winds aren't strong 672 00:12:17,509 --> 00:12:17,519 hour and a half the winds aren't strong 673 00:12:17,519 --> 00:12:19,430 hour and a half the winds aren't strong enough to perturb it on the scales that 674 00:12:19,430 --> 00:12:19,440 enough to perturb it on the scales that 675 00:12:19,440 --> 00:12:21,350 enough to perturb it on the scales that we're seeing here 676 00:12:21,350 --> 00:12:21,360 we're seeing here 677 00:12:21,360 --> 00:12:23,910 we're seeing here certainly over the next few days we will 678 00:12:23,910 --> 00:12:23,920 certainly over the next few days we will 679 00:12:23,920 --> 00:12:26,470 certainly over the next few days we will be watching all that material 680 00:12:26,470 --> 00:12:26,480 be watching all that material 681 00:12:26,480 --> 00:12:28,310 be watching all that material very closely to see how the winds 682 00:12:28,310 --> 00:12:28,320 very closely to see how the winds 683 00:12:28,320 --> 00:12:30,710 very closely to see how the winds distribute it and it will be distributed 684 00:12:30,710 --> 00:12:30,720 distribute it and it will be distributed 685 00:12:30,720 --> 00:12:32,230 distribute it and it will be distributed there's no question 686 00:12:32,230 --> 00:12:32,240 there's no question 687 00:12:32,240 --> 00:12:34,389 there's no question how do you want to mention that it looks 688 00:12:34,389 --> 00:12:34,399 how do you want to mention that it looks 689 00:12:34,399 --> 00:12:36,310 how do you want to mention that it looks as though some of the material in the 690 00:12:36,310 --> 00:12:36,320 as though some of the material in the 691 00:12:36,320 --> 00:12:39,350 as though some of the material in the spot from the a impact is being smeared 692 00:12:39,350 --> 00:12:39,360 spot from the a impact is being smeared 693 00:12:39,360 --> 00:12:40,870 spot from the a impact is being smeared out that's a good point gene yeah it 694 00:12:40,870 --> 00:12:40,880 out that's a good point gene yeah it 695 00:12:40,880 --> 00:12:41,990 out that's a good point gene yeah it does look like that in some of our 696 00:12:41,990 --> 00:12:42,000 does look like that in some of our 697 00:12:42,000 --> 00:12:44,310 does look like that in some of our recent images the the a impact site is 698 00:12:44,310 --> 00:12:44,320 recent images the the a impact site is 699 00:12:44,320 --> 00:12:47,110 recent images the the a impact site is not as crisp and sharp as it once was it 700 00:12:47,110 --> 00:12:47,120 not as crisp and sharp as it once was it 701 00:12:47,120 --> 00:12:48,550 not as crisp and sharp as it once was it looks kind of 702 00:12:48,550 --> 00:12:48,560 looks kind of 703 00:12:48,560 --> 00:12:50,949 looks kind of messy so as that material gets followed 704 00:12:50,949 --> 00:12:50,959 messy so as that material gets followed 705 00:12:50,959 --> 00:12:52,790 messy so as that material gets followed in fact it will be a very nice tracer 706 00:12:52,790 --> 00:12:52,800 in fact it will be a very nice tracer 707 00:12:52,800 --> 00:12:54,949 in fact it will be a very nice tracer for the velocities of these upper 708 00:12:54,949 --> 00:12:54,959 for the velocities of these upper 709 00:12:54,959 --> 00:12:56,710 for the velocities of these upper atmosphere winds for which there 710 00:12:56,710 --> 00:12:56,720 atmosphere winds for which there 711 00:12:56,720 --> 00:12:58,870 atmosphere winds for which there actually is no previous information so 712 00:12:58,870 --> 00:12:58,880 actually is no previous information so 713 00:12:58,880 --> 00:13:00,550 actually is no previous information so very important information about jupiter 714 00:13:00,550 --> 00:13:00,560 very important information about jupiter 715 00:13:00,560 --> 00:13:02,230 very important information about jupiter will come up from that 716 00:13:02,230 --> 00:13:02,240 will come up from that 717 00:13:02,240 --> 00:13:03,829 will come up from that take a question over here yeah i have 718 00:13:03,829 --> 00:13:03,839 take a question over here yeah i have 719 00:13:03,839 --> 00:13:05,350 take a question over here yeah i have two questions one can you estimate the 720 00:13:05,350 --> 00:13:05,360 two questions one can you estimate the 721 00:13:05,360 --> 00:13:06,470 two questions one can you estimate the distance between 722 00:13:06,470 --> 00:13:06,480 distance between 723 00:13:06,480 --> 00:13:08,949 distance between that d impact site and the new one the g 724 00:13:08,949 --> 00:13:08,959 that d impact site and the new one the g 725 00:13:08,959 --> 00:13:11,590 that d impact site and the new one the g one and also this morning john clark 726 00:13:11,590 --> 00:13:11,600 one and also this morning john clark 727 00:13:11,600 --> 00:13:13,350 one and also this morning john clark showed us uv um 728 00:13:13,350 --> 00:13:13,360 showed us uv um 729 00:13:13,360 --> 00:13:15,110 showed us uv um images that show that these impact sites 730 00:13:15,110 --> 00:13:15,120 images that show that these impact sites 731 00:13:15,120 --> 00:13:17,430 images that show that these impact sites when imaging the uv are much bigger than 732 00:13:17,430 --> 00:13:17,440 when imaging the uv are much bigger than 733 00:13:17,440 --> 00:13:18,870 when imaging the uv are much bigger than they are visually 734 00:13:18,870 --> 00:13:18,880 they are visually 735 00:13:18,880 --> 00:13:20,550 they are visually you suspect the same is true of this and 736 00:13:20,550 --> 00:13:20,560 you suspect the same is true of this and 737 00:13:20,560 --> 00:13:22,550 you suspect the same is true of this and that it is in fact even larger the area 738 00:13:22,550 --> 00:13:22,560 that it is in fact even larger the area 739 00:13:22,560 --> 00:13:24,389 that it is in fact even larger the area of disturbances in 740 00:13:24,389 --> 00:13:24,399 of disturbances in 741 00:13:24,399 --> 00:13:25,829 of disturbances in uv 742 00:13:25,829 --> 00:13:25,839 uv 743 00:13:25,839 --> 00:13:28,310 uv well i'll answer the second part first 744 00:13:28,310 --> 00:13:28,320 well i'll answer the second part first 745 00:13:28,320 --> 00:13:30,069 well i'll answer the second part first we'll wait and see when we get some uv 746 00:13:30,069 --> 00:13:30,079 we'll wait and see when we get some uv 747 00:13:30,079 --> 00:13:32,470 we'll wait and see when we get some uv images for sure it sure looks like that 748 00:13:32,470 --> 00:13:32,480 images for sure it sure looks like that 749 00:13:32,480 --> 00:13:34,870 images for sure it sure looks like that from the other three impact sites so 750 00:13:34,870 --> 00:13:34,880 from the other three impact sites so 751 00:13:34,880 --> 00:13:37,030 from the other three impact sites so probably yes probably it will be larger 752 00:13:37,030 --> 00:13:37,040 probably yes probably it will be larger 753 00:13:37,040 --> 00:13:38,150 probably yes probably it will be larger in the uv 754 00:13:38,150 --> 00:13:38,160 in the uv 755 00:13:38,160 --> 00:13:39,110 in the uv and 756 00:13:39,110 --> 00:13:39,120 and 757 00:13:39,120 --> 00:13:40,790 and what was the first question what's the 758 00:13:40,790 --> 00:13:40,800 what was the first question what's the 759 00:13:40,800 --> 00:13:42,949 what was the first question what's the what's the separation yeah can we do 760 00:13:42,949 --> 00:13:42,959 what's the separation yeah can we do 761 00:13:42,959 --> 00:13:46,870 what's the separation yeah can we do that yes we can have we done it not yet 762 00:13:46,870 --> 00:13:46,880 that yes we can have we done it not yet 763 00:13:46,880 --> 00:13:48,629 that yes we can have we done it not yet we'll get to it 764 00:13:48,629 --> 00:13:48,639 we'll get to it 765 00:13:48,639 --> 00:13:50,069 we'll get to it maybe they've done it already by the 766 00:13:50,069 --> 00:13:50,079 maybe they've done it already by the 767 00:13:50,079 --> 00:13:53,430 maybe they've done it already by the time i was coming out here 768 00:13:53,430 --> 00:13:53,440 769 00:13:53,440 --> 00:13:55,190 we'll take a question back here 770 00:13:55,190 --> 00:13:55,200 we'll take a question back here 771 00:13:55,200 --> 00:13:57,990 we'll take a question back here uh hi john rutherford with nbc can you 772 00:13:57,990 --> 00:13:58,000 uh hi john rutherford with nbc can you 773 00:13:58,000 --> 00:13:59,750 uh hi john rutherford with nbc can you talk about the uh what kind of impact 774 00:13:59,750 --> 00:13:59,760 talk about the uh what kind of impact 775 00:13:59,760 --> 00:14:01,189 talk about the uh what kind of impact this would have on earth if these things 776 00:14:01,189 --> 00:14:01,199 this would have on earth if these things 777 00:14:01,199 --> 00:14:03,750 this would have on earth if these things were hitting earth instead of jupiter 778 00:14:03,750 --> 00:14:03,760 were hitting earth instead of jupiter 779 00:14:03,760 --> 00:14:05,670 were hitting earth instead of jupiter well i i told gene i'd get them up here 780 00:14:05,670 --> 00:14:05,680 well i i told gene i'd get them up here 781 00:14:05,680 --> 00:14:07,269 well i i told gene i'd get them up here to answer that question well let me just 782 00:14:07,269 --> 00:14:07,279 to answer that question well let me just 783 00:14:07,279 --> 00:14:09,590 to answer that question well let me just point out again the scale remember that 784 00:14:09,590 --> 00:14:09,600 point out again the scale remember that 785 00:14:09,600 --> 00:14:11,350 point out again the scale remember that the earth is 786 00:14:11,350 --> 00:14:11,360 the earth is 787 00:14:11,360 --> 00:14:13,590 the earth is you know about the size of that ring you 788 00:14:13,590 --> 00:14:13,600 you know about the size of that ring you 789 00:14:13,600 --> 00:14:15,189 you know about the size of that ring you saw all right 790 00:14:15,189 --> 00:14:15,199 saw all right 791 00:14:15,199 --> 00:14:17,910 saw all right so the the scale the physical scale of 792 00:14:17,910 --> 00:14:17,920 so the the scale the physical scale of 793 00:14:17,920 --> 00:14:19,189 so the the scale the physical scale of this effect 794 00:14:19,189 --> 00:14:19,199 this effect 795 00:14:19,199 --> 00:14:21,350 this effect is terrestrial 796 00:14:21,350 --> 00:14:21,360 is terrestrial 797 00:14:21,360 --> 00:14:23,189 is terrestrial it's that big 798 00:14:23,189 --> 00:14:23,199 it's that big 799 00:14:23,199 --> 00:14:25,750 it's that big you know i i i wouldn't want to be on 800 00:14:25,750 --> 00:14:25,760 you know i i i wouldn't want to be on 801 00:14:25,760 --> 00:14:28,069 you know i i i wouldn't want to be on earth if one of these pieces landed on 802 00:14:28,069 --> 00:14:28,079 earth if one of these pieces landed on 803 00:14:28,079 --> 00:14:29,670 earth if one of these pieces landed on earth 804 00:14:29,670 --> 00:14:29,680 earth 805 00:14:29,680 --> 00:14:31,670 earth if you were going to ask what's the size 806 00:14:31,670 --> 00:14:31,680 if you were going to ask what's the size 807 00:14:31,680 --> 00:14:33,590 if you were going to ask what's the size crater this would made on on the earth 808 00:14:33,590 --> 00:14:33,600 crater this would made on on the earth 809 00:14:33,600 --> 00:14:35,269 crater this would made on on the earth if we're right about our estimate of the 810 00:14:35,269 --> 00:14:35,279 if we're right about our estimate of the 811 00:14:35,279 --> 00:14:37,189 if we're right about our estimate of the size and the energy 812 00:14:37,189 --> 00:14:37,199 size and the energy 813 00:14:37,199 --> 00:14:38,470 size and the energy if it hit 814 00:14:38,470 --> 00:14:38,480 if it hit 815 00:14:38,480 --> 00:14:41,590 if it hit a continent it would make a 60 kilometer 816 00:14:41,590 --> 00:14:41,600 a continent it would make a 60 kilometer 817 00:14:41,600 --> 00:14:43,910 a continent it would make a 60 kilometer diameter crater there abouts well how 818 00:14:43,910 --> 00:14:43,920 diameter crater there abouts well how 819 00:14:43,920 --> 00:14:45,430 diameter crater there abouts well how does that compare to the size of a state 820 00:14:45,430 --> 00:14:45,440 does that compare to the size of a state 821 00:14:45,440 --> 00:14:47,509 does that compare to the size of a state for example rhode island oh it's about 822 00:14:47,509 --> 00:14:47,519 for example rhode island oh it's about 823 00:14:47,519 --> 00:14:49,269 for example rhode island oh it's about 40 well it would it would pretty well 824 00:14:49,269 --> 00:14:49,279 40 well it would it would pretty well 825 00:14:49,279 --> 00:14:50,949 40 well it would it would pretty well the crater would pretty well cover rhode 826 00:14:50,949 --> 00:14:50,959 the crater would pretty well cover rhode 827 00:14:50,959 --> 00:14:52,389 the crater would pretty well cover rhode island yes 828 00:14:52,389 --> 00:14:52,399 island yes 829 00:14:52,399 --> 00:14:53,269 island yes uh 830 00:14:53,269 --> 00:14:53,279 uh 831 00:14:53,279 --> 00:14:54,949 uh the and the other thing is if you look 832 00:14:54,949 --> 00:14:54,959 the and the other thing is if you look 833 00:14:54,959 --> 00:14:57,189 the and the other thing is if you look at the size of of the material that's 834 00:14:57,189 --> 00:14:57,199 at the size of of the material that's 835 00:14:57,199 --> 00:14:59,430 at the size of of the material that's actually spread out and remember that's 836 00:14:59,430 --> 00:14:59,440 actually spread out and remember that's 837 00:14:59,440 --> 00:15:01,430 actually spread out and remember that's now gone up very high that would just go 838 00:15:01,430 --> 00:15:01,440 now gone up very high that would just go 839 00:15:01,440 --> 00:15:04,150 now gone up very high that would just go out ballistically all over the earth it 840 00:15:04,150 --> 00:15:04,160 out ballistically all over the earth it 841 00:15:04,160 --> 00:15:06,150 out ballistically all over the earth it it's enveloped the earth 842 00:15:06,150 --> 00:15:06,160 it's enveloped the earth 843 00:15:06,160 --> 00:15:08,150 it's enveloped the earth completely enveloped it's gone all over 844 00:15:08,150 --> 00:15:08,160 completely enveloped it's gone all over 845 00:15:08,160 --> 00:15:11,269 completely enveloped it's gone all over the earth so so that the material that's 846 00:15:11,269 --> 00:15:11,279 the earth so so that the material that's 847 00:15:11,279 --> 00:15:13,670 the earth so so that the material that's blown out of that crater 848 00:15:13,670 --> 00:15:13,680 blown out of that crater 849 00:15:13,680 --> 00:15:16,069 blown out of that crater would essentially blanket the earth with 850 00:15:16,069 --> 00:15:16,079 would essentially blanket the earth with 851 00:15:16,079 --> 00:15:18,710 would essentially blanket the earth with a layer of fine debris that would just 852 00:15:18,710 --> 00:15:18,720 a layer of fine debris that would just 853 00:15:18,720 --> 00:15:20,870 a layer of fine debris that would just block sunlight you just get dark all 854 00:15:20,870 --> 00:15:20,880 block sunlight you just get dark all 855 00:15:20,880 --> 00:15:23,910 block sunlight you just get dark all over the earth 856 00:15:23,910 --> 00:15:23,920 857 00:15:23,920 --> 00:15:25,110 right over here 858 00:15:25,110 --> 00:15:25,120 right over here 859 00:15:25,120 --> 00:15:26,710 right over here uh this is mark caro the houston 860 00:15:26,710 --> 00:15:26,720 uh this is mark caro the houston 861 00:15:26,720 --> 00:15:27,910 uh this is mark caro the houston chronicle 862 00:15:27,910 --> 00:15:27,920 chronicle 863 00:15:27,920 --> 00:15:30,870 chronicle regarding the sequence of three 864 00:15:30,870 --> 00:15:30,880 regarding the sequence of three 865 00:15:30,880 --> 00:15:33,189 regarding the sequence of three that happened every 12 hours later in 866 00:15:33,189 --> 00:15:33,199 that happened every 12 hours later in 867 00:15:33,199 --> 00:15:35,829 that happened every 12 hours later in the week could you is it possible to be 868 00:15:35,829 --> 00:15:35,839 the week could you is it possible to be 869 00:15:35,839 --> 00:15:37,990 the week could you is it possible to be a little more descriptive about how 870 00:15:37,990 --> 00:15:38,000 a little more descriptive about how 871 00:15:38,000 --> 00:15:40,150 a little more descriptive about how close those would be together and in 872 00:15:40,150 --> 00:15:40,160 close those would be together and in 873 00:15:40,160 --> 00:15:41,350 close those would be together and in some 874 00:15:41,350 --> 00:15:41,360 some 875 00:15:41,360 --> 00:15:43,350 some you said the same latitude but i didn't 876 00:15:43,350 --> 00:15:43,360 you said the same latitude but i didn't 877 00:15:43,360 --> 00:15:45,350 you said the same latitude but i didn't know that you meant the same 878 00:15:45,350 --> 00:15:45,360 know that you meant the same 879 00:15:45,360 --> 00:15:47,829 know that you meant the same quarter of the planet or stretched 880 00:15:47,829 --> 00:15:47,839 quarter of the planet or stretched 881 00:15:47,839 --> 00:15:49,829 quarter of the planet or stretched you know one third of the way around 882 00:15:49,829 --> 00:15:49,839 you know one third of the way around 883 00:15:49,839 --> 00:15:51,509 you know one third of the way around okay it's every 10 hours it's every 884 00:15:51,509 --> 00:15:51,519 okay it's every 10 hours it's every 885 00:15:51,519 --> 00:15:53,269 okay it's every 10 hours it's every jovian rotation 886 00:15:53,269 --> 00:15:53,279 jovian rotation 887 00:15:53,279 --> 00:15:54,389 jovian rotation and 888 00:15:54,389 --> 00:15:54,399 and 889 00:15:54,399 --> 00:15:55,269 and um 890 00:15:55,269 --> 00:15:55,279 um 891 00:15:55,279 --> 00:15:56,949 um i wish i brought the numbers with me 892 00:15:56,949 --> 00:15:56,959 i wish i brought the numbers with me 893 00:15:56,959 --> 00:15:59,269 i wish i brought the numbers with me they're very close in longitude 894 00:15:59,269 --> 00:15:59,279 they're very close in longitude 895 00:15:59,279 --> 00:16:00,949 they're very close in longitude on jupiter all of these are close in 896 00:16:00,949 --> 00:16:00,959 on jupiter all of these are close in 897 00:16:00,959 --> 00:16:02,790 on jupiter all of these are close in latitude they're all in the same band 898 00:16:02,790 --> 00:16:02,800 latitude they're all in the same band 899 00:16:02,800 --> 00:16:05,030 latitude they're all in the same band around the planet what these are 900 00:16:05,030 --> 00:16:05,040 around the planet what these are 901 00:16:05,040 --> 00:16:06,550 around the planet what these are striking about that group of three 902 00:16:06,550 --> 00:16:06,560 striking about that group of three 903 00:16:06,560 --> 00:16:08,230 striking about that group of three coming up is that they're all close in 904 00:16:08,230 --> 00:16:08,240 coming up is that they're all close in 905 00:16:08,240 --> 00:16:10,949 coming up is that they're all close in longitude and i i can't remember the 906 00:16:10,949 --> 00:16:10,959 longitude and i i can't remember the 907 00:16:10,959 --> 00:16:12,790 longitude and i i can't remember the number off the top of my head i think it 908 00:16:12,790 --> 00:16:12,800 number off the top of my head i think it 909 00:16:12,800 --> 00:16:14,870 number off the top of my head i think it might be within 10 degrees 910 00:16:14,870 --> 00:16:14,880 might be within 10 degrees 911 00:16:14,880 --> 00:16:17,430 might be within 10 degrees certainly all if they have sizes 912 00:16:17,430 --> 00:16:17,440 certainly all if they have sizes 913 00:16:17,440 --> 00:16:20,069 certainly all if they have sizes comparable to say a or 914 00:16:20,069 --> 00:16:20,079 comparable to say a or 915 00:16:20,079 --> 00:16:22,389 comparable to say a or c or e which we've we saw 916 00:16:22,389 --> 00:16:22,399 c or e which we've we saw 917 00:16:22,399 --> 00:16:23,910 c or e which we've we saw earlier this morning 918 00:16:23,910 --> 00:16:23,920 earlier this morning 919 00:16:23,920 --> 00:16:28,949 earlier this morning all those regions will overlap 920 00:16:28,949 --> 00:16:28,959 921 00:16:28,959 --> 00:16:30,550 okay we've we've got a question right 922 00:16:30,550 --> 00:16:30,560 okay we've we've got a question right 923 00:16:30,560 --> 00:16:33,189 okay we've we've got a question right over here 924 00:16:33,189 --> 00:16:33,199 925 00:16:33,199 --> 00:16:35,269 deborah savarenko at reuters this is a 926 00:16:35,269 --> 00:16:35,279 deborah savarenko at reuters this is a 927 00:16:35,279 --> 00:16:36,790 deborah savarenko at reuters this is a really elementary question but my 928 00:16:36,790 --> 00:16:36,800 really elementary question but my 929 00:16:36,800 --> 00:16:38,069 really elementary question but my editors have been asking and i haven't 930 00:16:38,069 --> 00:16:38,079 editors have been asking and i haven't 931 00:16:38,079 --> 00:16:41,030 editors have been asking and i haven't come up with a good response 932 00:16:41,030 --> 00:16:41,040 come up with a good response 933 00:16:41,040 --> 00:16:43,430 come up with a good response i need to make clear to our readers the 934 00:16:43,430 --> 00:16:43,440 i need to make clear to our readers the 935 00:16:43,440 --> 00:16:45,430 i need to make clear to our readers the difference in size between earth and 936 00:16:45,430 --> 00:16:45,440 difference in size between earth and 937 00:16:45,440 --> 00:16:47,509 difference in size between earth and jupiter how many more times 938 00:16:47,509 --> 00:16:47,519 jupiter how many more times 939 00:16:47,519 --> 00:16:51,110 jupiter how many more times bigger is jupiter than earth 940 00:16:51,110 --> 00:16:51,120 bigger is jupiter than earth 941 00:16:51,120 --> 00:16:53,030 bigger is jupiter than earth well i like to put it in terms of the 942 00:16:53,030 --> 00:16:53,040 well i like to put it in terms of the 943 00:16:53,040 --> 00:16:55,030 well i like to put it in terms of the great red spot the storm you see on 944 00:16:55,030 --> 00:16:55,040 great red spot the storm you see on 945 00:16:55,040 --> 00:16:56,230 great red spot the storm you see on jupiter 946 00:16:56,230 --> 00:16:56,240 jupiter 947 00:16:56,240 --> 00:16:58,230 jupiter you're familiar with the red spot you 948 00:16:58,230 --> 00:16:58,240 you're familiar with the red spot you 949 00:16:58,240 --> 00:17:00,550 you're familiar with the red spot you could fit two earths there it is you 950 00:17:00,550 --> 00:17:00,560 could fit two earths there it is you 951 00:17:00,560 --> 00:17:03,110 could fit two earths there it is you could fit two earths inside that red 952 00:17:03,110 --> 00:17:03,120 could fit two earths inside that red 953 00:17:03,120 --> 00:17:05,990 could fit two earths inside that red spot 954 00:17:05,990 --> 00:17:06,000 955 00:17:06,000 --> 00:17:07,590 that 956 00:17:07,590 --> 00:17:07,600 that 957 00:17:07,600 --> 00:17:09,829 that how many do you know the number the 958 00:17:09,829 --> 00:17:09,839 how many do you know the number the 959 00:17:09,839 --> 00:17:12,949 how many do you know the number the diameter is about 12 times greater for 960 00:17:12,949 --> 00:17:12,959 diameter is about 12 times greater for 961 00:17:12,959 --> 00:17:15,829 diameter is about 12 times greater for jupiter 12 times 12 earth diameters 962 00:17:15,829 --> 00:17:15,839 jupiter 12 times 12 earth diameters 963 00:17:15,839 --> 00:17:19,110 jupiter 12 times 12 earth diameters roughly 964 00:17:19,110 --> 00:17:19,120 965 00:17:19,120 --> 00:17:21,029 paul 966 00:17:21,029 --> 00:17:21,039 paul 967 00:17:21,039 --> 00:17:25,189 paul um 968 00:17:25,189 --> 00:17:25,199 969 00:17:25,199 --> 00:17:28,069 yeah paul reese of ap and in the uh 970 00:17:28,069 --> 00:17:28,079 yeah paul reese of ap and in the uh 971 00:17:28,079 --> 00:17:30,150 yeah paul reese of ap and in the uh in jupiter's black eye there the pupil 972 00:17:30,150 --> 00:17:30,160 in jupiter's black eye there the pupil 973 00:17:30,160 --> 00:17:33,190 in jupiter's black eye there the pupil of it there is a white spot uh 974 00:17:33,190 --> 00:17:33,200 of it there is a white spot uh 975 00:17:33,200 --> 00:17:34,950 of it there is a white spot uh i noticed in the earlier earlier 976 00:17:34,950 --> 00:17:34,960 i noticed in the earlier earlier 977 00:17:34,960 --> 00:17:36,630 i noticed in the earlier earlier pictures do you have any idea what that 978 00:17:36,630 --> 00:17:36,640 pictures do you have any idea what that 979 00:17:36,640 --> 00:17:39,029 pictures do you have any idea what that white spot is an artifact or is that uh 980 00:17:39,029 --> 00:17:39,039 white spot is an artifact or is that uh 981 00:17:39,039 --> 00:17:40,470 white spot is an artifact or is that uh i'd have to see the graphic to know 982 00:17:40,470 --> 00:17:40,480 i'd have to see the graphic to know 983 00:17:40,480 --> 00:17:42,150 i'd have to see the graphic to know exactly what you're talking about see 984 00:17:42,150 --> 00:17:42,160 exactly what you're talking about see 985 00:17:42,160 --> 00:17:43,190 exactly what you're talking about see that uh 986 00:17:43,190 --> 00:17:43,200 that uh 987 00:17:43,200 --> 00:17:45,190 that uh right right above the pupil there i 988 00:17:45,190 --> 00:17:45,200 right right above the pupil there i 989 00:17:45,200 --> 00:17:47,430 right right above the pupil there i would guess that's just a cosmic ray we 990 00:17:47,430 --> 00:17:47,440 would guess that's just a cosmic ray we 991 00:17:47,440 --> 00:17:49,590 would guess that's just a cosmic ray we that's a an instrumental effect in the 992 00:17:49,590 --> 00:17:49,600 that's a an instrumental effect in the 993 00:17:49,600 --> 00:17:52,150 that's a an instrumental effect in the detector it's not a real white it's not 994 00:17:52,150 --> 00:17:52,160 detector it's not a real white it's not 995 00:17:52,160 --> 00:17:54,549 detector it's not a real white it's not a white spot okay i'll look at it we 996 00:17:54,549 --> 00:17:54,559 a white spot okay i'll look at it we 997 00:17:54,559 --> 00:17:55,990 a white spot okay i'll look at it we didn't have time to really clean these 998 00:17:55,990 --> 00:17:56,000 didn't have time to really clean these 999 00:17:56,000 --> 00:17:58,390 didn't have time to really clean these images in the last 10 hours and i want 1000 00:17:58,390 --> 00:17:58,400 images in the last 10 hours and i want 1001 00:17:58,400 --> 00:17:59,830 images in the last 10 hours and i want to make very sure i understand the 1002 00:17:59,830 --> 00:17:59,840 to make very sure i understand the 1003 00:17:59,840 --> 00:18:02,630 to make very sure i understand the comparative sizes here uh in fact this 1004 00:18:02,630 --> 00:18:02,640 comparative sizes here uh in fact this 1005 00:18:02,640 --> 00:18:04,390 comparative sizes here uh in fact this is this is three concentric rings you 1006 00:18:04,390 --> 00:18:04,400 is this is three concentric rings you 1007 00:18:04,400 --> 00:18:05,669 is this is three concentric rings you got a dark 1008 00:18:05,669 --> 00:18:05,679 got a dark 1009 00:18:05,679 --> 00:18:07,909 got a dark um element in the very center then you 1010 00:18:07,909 --> 00:18:07,919 um element in the very center then you 1011 00:18:07,919 --> 00:18:10,230 um element in the very center then you got you got a very uh uh nearly perfect 1012 00:18:10,230 --> 00:18:10,240 got you got a very uh uh nearly perfect 1013 00:18:10,240 --> 00:18:11,430 got you got a very uh uh nearly perfect ring around it and then you got the 1014 00:18:11,430 --> 00:18:11,440 ring around it and then you got the 1015 00:18:11,440 --> 00:18:13,350 ring around it and then you got the smudge on the outside the earth is the 1016 00:18:13,350 --> 00:18:13,360 smudge on the outside the earth is the 1017 00:18:13,360 --> 00:18:16,470 smudge on the outside the earth is the size of what exactly of those three okay 1018 00:18:16,470 --> 00:18:16,480 size of what exactly of those three okay 1019 00:18:16,480 --> 00:18:18,390 size of what exactly of those three okay i'll give you some numbers to chew on 1020 00:18:18,390 --> 00:18:18,400 i'll give you some numbers to chew on 1021 00:18:18,400 --> 00:18:20,310 i'll give you some numbers to chew on well can you just compare it to that 1022 00:18:20,310 --> 00:18:20,320 well can you just compare it to that 1023 00:18:20,320 --> 00:18:23,350 well can you just compare it to that yeah well yeah the the 1024 00:18:23,350 --> 00:18:23,360 yeah well yeah the the 1025 00:18:23,360 --> 00:18:25,270 yeah well yeah the the the earth is a little bit larger than 1026 00:18:25,270 --> 00:18:25,280 the earth is a little bit larger than 1027 00:18:25,280 --> 00:18:29,669 the earth is a little bit larger than that the black ring the sharp black ring 1028 00:18:29,669 --> 00:18:29,679 that the black ring the sharp black ring 1029 00:18:29,679 --> 00:18:31,190 that the black ring the sharp black ring the earth is a little bit larger than 1030 00:18:31,190 --> 00:18:31,200 the earth is a little bit larger than 1031 00:18:31,200 --> 00:18:33,909 the earth is a little bit larger than the sharp black ring but the earth is 1032 00:18:33,909 --> 00:18:33,919 the sharp black ring but the earth is 1033 00:18:33,919 --> 00:18:37,990 the sharp black ring but the earth is smaller than the whole smudge area 1034 00:18:37,990 --> 00:18:38,000 smaller than the whole smudge area 1035 00:18:38,000 --> 00:18:43,029 smaller than the whole smudge area okay 1036 00:18:43,029 --> 00:18:43,039 1037 00:18:43,039 --> 00:18:45,909 on the far end over right over here 1038 00:18:45,909 --> 00:18:45,919 on the far end over right over here 1039 00:18:45,919 --> 00:18:48,150 on the far end over right over here uh david chandler from the boston globe 1040 00:18:48,150 --> 00:18:48,160 uh david chandler from the boston globe 1041 00:18:48,160 --> 00:18:50,710 uh david chandler from the boston globe um i know when these images first came 1042 00:18:50,710 --> 00:18:50,720 um i know when these images first came 1043 00:18:50,720 --> 00:18:53,110 um i know when these images first came in saturday night you were surprised to 1044 00:18:53,110 --> 00:18:53,120 in saturday night you were surprised to 1045 00:18:53,120 --> 00:18:54,950 in saturday night you were surprised to see black smudges rather than white 1046 00:18:54,950 --> 00:18:54,960 see black smudges rather than white 1047 00:18:54,960 --> 00:18:56,710 see black smudges rather than white smudges and i don't know if i've missed 1048 00:18:56,710 --> 00:18:56,720 smudges and i don't know if i've missed 1049 00:18:56,720 --> 00:18:57,909 smudges and i don't know if i've missed something in between but what's your 1050 00:18:57,909 --> 00:18:57,919 something in between but what's your 1051 00:18:57,919 --> 00:18:59,590 something in between but what's your best thinking at this point about why 1052 00:18:59,590 --> 00:18:59,600 best thinking at this point about why 1053 00:18:59,600 --> 00:19:02,710 best thinking at this point about why these smudges are black 1054 00:19:02,710 --> 00:19:02,720 these smudges are black 1055 00:19:02,720 --> 00:19:04,310 these smudges are black i think our 1056 00:19:04,310 --> 00:19:04,320 i think our 1057 00:19:04,320 --> 00:19:07,190 i think our the theories are are numerous um 1058 00:19:07,190 --> 00:19:07,200 the theories are are numerous um 1059 00:19:07,200 --> 00:19:08,549 the theories are are numerous um many people 1060 00:19:08,549 --> 00:19:08,559 many people 1061 00:19:08,559 --> 00:19:11,029 many people are theorizing that a lot of what we're 1062 00:19:11,029 --> 00:19:11,039 are theorizing that a lot of what we're 1063 00:19:11,039 --> 00:19:14,470 are theorizing that a lot of what we're seeing is is some commentary material 1064 00:19:14,470 --> 00:19:14,480 seeing is is some commentary material 1065 00:19:14,480 --> 00:19:16,230 seeing is is some commentary material comets are very dark 1066 00:19:16,230 --> 00:19:16,240 comets are very dark 1067 00:19:16,240 --> 00:19:17,270 comets are very dark and 1068 00:19:17,270 --> 00:19:17,280 and 1069 00:19:17,280 --> 00:19:19,430 and it also might be material from jupiter 1070 00:19:19,430 --> 00:19:19,440 it also might be material from jupiter 1071 00:19:19,440 --> 00:19:21,590 it also might be material from jupiter that's deeper down that we're not used 1072 00:19:21,590 --> 00:19:21,600 that's deeper down that we're not used 1073 00:19:21,600 --> 00:19:23,990 that's deeper down that we're not used to seeing higher up and that material 1074 00:19:23,990 --> 00:19:24,000 to seeing higher up and that material 1075 00:19:24,000 --> 00:19:25,270 to seeing higher up and that material could very well be a very different 1076 00:19:25,270 --> 00:19:25,280 could very well be a very different 1077 00:19:25,280 --> 00:19:26,470 could very well be a very different color 1078 00:19:26,470 --> 00:19:26,480 color 1079 00:19:26,480 --> 00:19:27,830 color i don't have a very good answer for that 1080 00:19:27,830 --> 00:19:27,840 i don't have a very good answer for that 1081 00:19:27,840 --> 00:19:29,270 i don't have a very good answer for that question right now 1082 00:19:29,270 --> 00:19:29,280 question right now 1083 00:19:29,280 --> 00:19:31,750 question right now i think i was surprised because 1084 00:19:31,750 --> 00:19:31,760 i think i was surprised because 1085 00:19:31,760 --> 00:19:33,270 i think i was surprised because most of the 1086 00:19:33,270 --> 00:19:33,280 most of the 1087 00:19:33,280 --> 00:19:36,310 most of the most of the fresh features that we see 1088 00:19:36,310 --> 00:19:36,320 most of the fresh features that we see 1089 00:19:36,320 --> 00:19:38,630 most of the fresh features that we see on these outer planets that i'm aware of 1090 00:19:38,630 --> 00:19:38,640 on these outer planets that i'm aware of 1091 00:19:38,640 --> 00:19:41,510 on these outer planets that i'm aware of tend to be white and bright and so 1092 00:19:41,510 --> 00:19:41,520 tend to be white and bright and so 1093 00:19:41,520 --> 00:19:43,029 tend to be white and bright and so that's why i expected them to be that 1094 00:19:43,029 --> 00:19:43,039 that's why i expected them to be that 1095 00:19:43,039 --> 00:19:47,510 that's why i expected them to be that color and i was very surprised 1096 00:19:47,510 --> 00:19:47,520 1097 00:19:47,520 --> 00:19:49,270 in the plume picture that you showed 1098 00:19:49,270 --> 00:19:49,280 in the plume picture that you showed 1099 00:19:49,280 --> 00:19:50,870 in the plume picture that you showed today and as well as on the earlier 1100 00:19:50,870 --> 00:19:50,880 today and as well as on the earlier 1101 00:19:50,880 --> 00:19:53,270 today and as well as on the earlier plume pictures you see a bright plume 1102 00:19:53,270 --> 00:19:53,280 plume pictures you see a bright plume 1103 00:19:53,280 --> 00:19:55,750 plume pictures you see a bright plume and then there's a dark region before 1104 00:19:55,750 --> 00:19:55,760 and then there's a dark region before 1105 00:19:55,760 --> 00:19:57,590 and then there's a dark region before the limb of the planet 1106 00:19:57,590 --> 00:19:57,600 the limb of the planet 1107 00:19:57,600 --> 00:20:00,630 the limb of the planet why why is there that dark region great 1108 00:20:00,630 --> 00:20:00,640 why why is there that dark region great 1109 00:20:00,640 --> 00:20:02,630 why why is there that dark region great question there's two reasons there's 1110 00:20:02,630 --> 00:20:02,640 question there's two reasons there's 1111 00:20:02,640 --> 00:20:04,390 question there's two reasons there's there's a dark region there the first is 1112 00:20:04,390 --> 00:20:04,400 there's a dark region there the first is 1113 00:20:04,400 --> 00:20:08,150 there's a dark region there the first is that we're seeing the crescent 1114 00:20:08,150 --> 00:20:08,160 that we're seeing the crescent 1115 00:20:08,160 --> 00:20:10,950 that we're seeing the crescent of the shadow of jupiter jupiter is not 1116 00:20:10,950 --> 00:20:10,960 of the shadow of jupiter jupiter is not 1117 00:20:10,960 --> 00:20:14,230 of the shadow of jupiter jupiter is not fully illuminated okay the sun is a 1118 00:20:14,230 --> 00:20:14,240 fully illuminated okay the sun is a 1119 00:20:14,240 --> 00:20:16,230 fully illuminated okay the sun is a little bit off to an angle about 10 1120 00:20:16,230 --> 00:20:16,240 little bit off to an angle about 10 1121 00:20:16,240 --> 00:20:18,549 little bit off to an angle about 10 degrees so there's a little tiny sliver 1122 00:20:18,549 --> 00:20:18,559 degrees so there's a little tiny sliver 1123 00:20:18,559 --> 00:20:20,630 degrees so there's a little tiny sliver that's unilluminated just like we see 1124 00:20:20,630 --> 00:20:20,640 that's unilluminated just like we see 1125 00:20:20,640 --> 00:20:22,950 that's unilluminated just like we see the moon in the sky has pieces that 1126 00:20:22,950 --> 00:20:22,960 the moon in the sky has pieces that 1127 00:20:22,960 --> 00:20:25,190 the moon in the sky has pieces that aren't always illuminated that's part of 1128 00:20:25,190 --> 00:20:25,200 aren't always illuminated that's part of 1129 00:20:25,200 --> 00:20:26,150 aren't always illuminated that's part of it 1130 00:20:26,150 --> 00:20:26,160 it 1131 00:20:26,160 --> 00:20:28,149 it but the other part is that these plumes 1132 00:20:28,149 --> 00:20:28,159 but the other part is that these plumes 1133 00:20:28,159 --> 00:20:29,990 but the other part is that these plumes are so high 1134 00:20:29,990 --> 00:20:30,000 are so high 1135 00:20:30,000 --> 00:20:32,950 are so high that the shadow of jupiter 1136 00:20:32,950 --> 00:20:32,960 that the shadow of jupiter 1137 00:20:32,960 --> 00:20:34,470 that the shadow of jupiter just a little sliver of the shadow of 1138 00:20:34,470 --> 00:20:34,480 just a little sliver of the shadow of 1139 00:20:34,480 --> 00:20:36,549 just a little sliver of the shadow of jupiter itself 1140 00:20:36,549 --> 00:20:36,559 jupiter itself 1141 00:20:36,559 --> 00:20:40,070 jupiter itself is is illuminating is is preventing the 1142 00:20:40,070 --> 00:20:40,080 is is illuminating is is preventing the 1143 00:20:40,080 --> 00:20:42,310 is is illuminating is is preventing the sunlight from reaching that 1144 00:20:42,310 --> 00:20:42,320 sunlight from reaching that 1145 00:20:42,320 --> 00:20:43,909 sunlight from reaching that and we're doing some calculations right 1146 00:20:43,909 --> 00:20:43,919 and we're doing some calculations right 1147 00:20:43,919 --> 00:20:47,029 and we're doing some calculations right now to tell you very precise heights of 1148 00:20:47,029 --> 00:20:47,039 now to tell you very precise heights of 1149 00:20:47,039 --> 00:20:49,510 now to tell you very precise heights of these things we're working on it right 1150 00:20:49,510 --> 00:20:49,520 these things we're working on it right 1151 00:20:49,520 --> 00:20:52,470 these things we're working on it right now but most of that is the 1152 00:20:52,470 --> 00:20:52,480 now but most of that is the 1153 00:20:52,480 --> 00:20:55,110 now but most of that is the limb of the planet a good way to look is 1154 00:20:55,110 --> 00:20:55,120 limb of the planet a good way to look is 1155 00:20:55,120 --> 00:20:57,350 limb of the planet a good way to look is the bottom image if you could put the 1156 00:20:57,350 --> 00:20:57,360 the bottom image if you could put the 1157 00:20:57,360 --> 00:21:00,870 the bottom image if you could put the graphic up the bottom image you see the 1158 00:21:00,870 --> 00:21:00,880 graphic up the bottom image you see the 1159 00:21:00,880 --> 00:21:03,430 graphic up the bottom image you see the edge of jupiter and then you see that 1160 00:21:03,430 --> 00:21:03,440 edge of jupiter and then you see that 1161 00:21:03,440 --> 00:21:06,230 edge of jupiter and then you see that smear the pancake that pancake is 1162 00:21:06,230 --> 00:21:06,240 smear the pancake that pancake is 1163 00:21:06,240 --> 00:21:08,549 smear the pancake that pancake is sitting on the planet okay that 1164 00:21:08,549 --> 00:21:08,559 sitting on the planet okay that 1165 00:21:08,559 --> 00:21:10,710 sitting on the planet okay that pancake's not floating in outer space 1166 00:21:10,710 --> 00:21:10,720 pancake's not floating in outer space 1167 00:21:10,720 --> 00:21:12,789 pancake's not floating in outer space the pancake is in the atmosphere and 1168 00:21:12,789 --> 00:21:12,799 the pancake is in the atmosphere and 1169 00:21:12,799 --> 00:21:15,110 the pancake is in the atmosphere and that thin little strip there 1170 00:21:15,110 --> 00:21:15,120 that thin little strip there 1171 00:21:15,120 --> 00:21:17,830 that thin little strip there that is the that's the 1172 00:21:17,830 --> 00:21:17,840 that is the that's the 1173 00:21:17,840 --> 00:21:22,870 that is the that's the that's the uniluminated part of jupiter 1174 00:21:22,870 --> 00:21:22,880 1175 00:21:22,880 --> 00:21:24,310 question over here 1176 00:21:24,310 --> 00:21:24,320 question over here 1177 00:21:24,320 --> 00:21:26,710 question over here yes jan smith with fox television in 1178 00:21:26,710 --> 00:21:26,720 yes jan smith with fox television in 1179 00:21:26,720 --> 00:21:28,549 yes jan smith with fox television in revising this morning's estimate of the 1180 00:21:28,549 --> 00:21:28,559 revising this morning's estimate of the 1181 00:21:28,559 --> 00:21:30,789 revising this morning's estimate of the power of the explosion how do you now 1182 00:21:30,789 --> 00:21:30,799 power of the explosion how do you now 1183 00:21:30,799 --> 00:21:32,789 power of the explosion how do you now compare it to the size of the world's 1184 00:21:32,789 --> 00:21:32,799 compare it to the size of the world's 1185 00:21:32,799 --> 00:21:35,029 compare it to the size of the world's bomb arsenal 1186 00:21:35,029 --> 00:21:35,039 bomb arsenal 1187 00:21:35,039 --> 00:21:37,510 bomb arsenal okay 1188 00:21:37,510 --> 00:21:37,520 1189 00:21:37,520 --> 00:21:39,029 putting it in megadens i didn't really 1190 00:21:39,029 --> 00:21:39,039 putting it in megadens i didn't really 1191 00:21:39,039 --> 00:21:40,630 putting it in megadens i didn't really change my estimate of the energy i just 1192 00:21:40,630 --> 00:21:40,640 change my estimate of the energy i just 1193 00:21:40,640 --> 00:21:41,510 change my estimate of the energy i just made it 1194 00:21:41,510 --> 00:21:41,520 made it 1195 00:21:41,520 --> 00:21:44,390 made it error in converting it to megatons and i 1196 00:21:44,390 --> 00:21:44,400 error in converting it to megatons and i 1197 00:21:44,400 --> 00:21:45,990 error in converting it to megatons and i guess we have a little disagreement the 1198 00:21:45,990 --> 00:21:46,000 guess we have a little disagreement the 1199 00:21:46,000 --> 00:21:48,390 guess we have a little disagreement the number i've always used as the world's 1200 00:21:48,390 --> 00:21:48,400 number i've always used as the world's 1201 00:21:48,400 --> 00:21:51,990 number i've always used as the world's arsenals is 10 000 megatons but there 1202 00:21:51,990 --> 00:21:52,000 arsenals is 10 000 megatons but there 1203 00:21:52,000 --> 00:21:53,830 arsenals is 10 000 megatons but there are other numbers floating around and i 1204 00:21:53,830 --> 00:21:53,840 are other numbers floating around and i 1205 00:21:53,840 --> 00:21:56,310 are other numbers floating around and i guess the real number is still a state 1206 00:21:56,310 --> 00:21:56,320 guess the real number is still a state 1207 00:21:56,320 --> 00:21:58,390 guess the real number is still a state secret 1208 00:21:58,390 --> 00:21:58,400 secret 1209 00:21:58,400 --> 00:22:00,950 secret so i've used what's been commonly used 1210 00:22:00,950 --> 00:22:00,960 so i've used what's been commonly used 1211 00:22:00,960 --> 00:22:02,230 so i've used what's been commonly used in some of the literature at ten 1212 00:22:02,230 --> 00:22:02,240 in some of the literature at ten 1213 00:22:02,240 --> 00:22:04,230 in some of the literature at ten thousand megatons so 1214 00:22:04,230 --> 00:22:04,240 thousand megatons so 1215 00:22:04,240 --> 00:22:06,390 thousand megatons so uh if you compare that with the energy 1216 00:22:06,390 --> 00:22:06,400 uh if you compare that with the energy 1217 00:22:06,400 --> 00:22:09,990 uh if you compare that with the energy for new our estimate of nucleus a 1218 00:22:09,990 --> 00:22:10,000 for new our estimate of nucleus a 1219 00:22:10,000 --> 00:22:13,430 for new our estimate of nucleus a nucleus a energy is about 20 times that 1220 00:22:13,430 --> 00:22:13,440 nucleus a energy is about 20 times that 1221 00:22:13,440 --> 00:22:15,830 nucleus a energy is about 20 times that now i've heard bandied about just in 1222 00:22:15,830 --> 00:22:15,840 now i've heard bandied about just in 1223 00:22:15,840 --> 00:22:18,390 now i've heard bandied about just in this room in the last half hour a much 1224 00:22:18,390 --> 00:22:18,400 this room in the last half hour a much 1225 00:22:18,400 --> 00:22:20,149 this room in the last half hour a much higher figure for the nuclear arsenal 1226 00:22:20,149 --> 00:22:20,159 higher figure for the nuclear arsenal 1227 00:22:20,159 --> 00:22:23,270 higher figure for the nuclear arsenal something like about 80 000 megatons so 1228 00:22:23,270 --> 00:22:23,280 something like about 80 000 megatons so 1229 00:22:23,280 --> 00:22:25,029 something like about 80 000 megatons so then it would only be about a factor of 1230 00:22:25,029 --> 00:22:25,039 then it would only be about a factor of 1231 00:22:25,039 --> 00:22:26,789 then it would only be about a factor of three higher 1232 00:22:26,789 --> 00:22:26,799 three higher 1233 00:22:26,799 --> 00:22:29,909 three higher when you get to six million megatons 1234 00:22:29,909 --> 00:22:29,919 when you get to six million megatons 1235 00:22:29,919 --> 00:22:32,310 when you get to six million megatons that's a whole lot higher i mean that's 1236 00:22:32,310 --> 00:22:32,320 that's a whole lot higher i mean that's 1237 00:22:32,320 --> 00:22:35,029 that's a whole lot higher i mean that's getting in the ballpark of 400 or 500 1238 00:22:35,029 --> 00:22:35,039 getting in the ballpark of 400 or 500 1239 00:22:35,039 --> 00:22:36,310 getting in the ballpark of 400 or 500 times the 1240 00:22:36,310 --> 00:22:36,320 times the 1241 00:22:36,320 --> 00:22:38,230 times the what i think is the more conventional 1242 00:22:38,230 --> 00:22:38,240 what i think is the more conventional 1243 00:22:38,240 --> 00:22:39,590 what i think is the more conventional published estimate of the world's 1244 00:22:39,590 --> 00:22:39,600 published estimate of the world's 1245 00:22:39,600 --> 00:22:42,630 published estimate of the world's nuclear arsenal 1246 00:22:42,630 --> 00:22:42,640 nuclear arsenal 1247 00:22:42,640 --> 00:22:47,029 nuclear arsenal okay we've got a question right here 1248 00:22:47,029 --> 00:22:47,039 1249 00:22:47,039 --> 00:22:48,710 chris leach nhk 1250 00:22:48,710 --> 00:22:48,720 chris leach nhk 1251 00:22:48,720 --> 00:22:50,710 chris leach nhk what was the the actual size of the 1252 00:22:50,710 --> 00:22:50,720 what was the the actual size of the 1253 00:22:50,720 --> 00:22:53,110 what was the the actual size of the fragment and also what was the the time 1254 00:22:53,110 --> 00:22:53,120 fragment and also what was the the time 1255 00:22:53,120 --> 00:22:55,190 fragment and also what was the the time that the fragment actually impacted into 1256 00:22:55,190 --> 00:22:55,200 that the fragment actually impacted into 1257 00:22:55,200 --> 00:22:56,789 that the fragment actually impacted into jupiter 1258 00:22:56,789 --> 00:22:56,799 jupiter 1259 00:22:56,799 --> 00:22:58,789 jupiter those are two questions for which we 1260 00:22:58,789 --> 00:22:58,799 those are two questions for which we 1261 00:22:58,799 --> 00:23:01,270 those are two questions for which we would very much like to have the answers 1262 00:23:01,270 --> 00:23:01,280 would very much like to have the answers 1263 00:23:01,280 --> 00:23:02,470 would very much like to have the answers to 1264 00:23:02,470 --> 00:23:02,480 to 1265 00:23:02,480 --> 00:23:03,830 to um 1266 00:23:03,830 --> 00:23:03,840 um 1267 00:23:03,840 --> 00:23:06,950 um the time betw between uh well the time 1268 00:23:06,950 --> 00:23:06,960 the time betw between uh well the time 1269 00:23:06,960 --> 00:23:08,630 the time betw between uh well the time of that first image that i showed you 1270 00:23:08,630 --> 00:23:08,640 of that first image that i showed you 1271 00:23:08,640 --> 00:23:10,390 of that first image that i showed you with the tiny tip of the plume was 1272 00:23:10,390 --> 00:23:10,400 with the tiny tip of the plume was 1273 00:23:10,400 --> 00:23:13,590 with the tiny tip of the plume was sticking over that was 7 33 1274 00:23:13,590 --> 00:23:13,600 sticking over that was 7 33 1275 00:23:13,600 --> 00:23:15,909 sticking over that was 7 33 that probably happened that image 1276 00:23:15,909 --> 00:23:15,919 that probably happened that image 1277 00:23:15,919 --> 00:23:18,310 that probably happened that image probably occurred within say five 1278 00:23:18,310 --> 00:23:18,320 probably occurred within say five 1279 00:23:18,320 --> 00:23:20,630 probably occurred within say five minutes of the impact itself i would 1280 00:23:20,630 --> 00:23:20,640 minutes of the impact itself i would 1281 00:23:20,640 --> 00:23:22,390 minutes of the impact itself i would guess there's probably only a delay of a 1282 00:23:22,390 --> 00:23:22,400 guess there's probably only a delay of a 1283 00:23:22,400 --> 00:23:25,990 guess there's probably only a delay of a couple of minutes right so so 7 33 1284 00:23:25,990 --> 00:23:26,000 couple of minutes right so so 7 33 1285 00:23:26,000 --> 00:23:28,149 couple of minutes right so so 7 33 minus five minutes somewhere in that 1286 00:23:28,149 --> 00:23:28,159 minus five minutes somewhere in that 1287 00:23:28,159 --> 00:23:30,549 minus five minutes somewhere in that time period is when the impact occurred 1288 00:23:30,549 --> 00:23:30,559 time period is when the impact occurred 1289 00:23:30,559 --> 00:23:31,590 time period is when the impact occurred and 1290 00:23:31,590 --> 00:23:31,600 and 1291 00:23:31,600 --> 00:23:32,710 and i can't remember the other question 1292 00:23:32,710 --> 00:23:32,720 i can't remember the other question 1293 00:23:32,720 --> 00:23:35,029 i can't remember the other question again 1294 00:23:35,029 --> 00:23:35,039 1295 00:23:35,039 --> 00:23:36,950 we still don't know the sizes of these 1296 00:23:36,950 --> 00:23:36,960 we still don't know the sizes of these 1297 00:23:36,960 --> 00:23:38,710 we still don't know the sizes of these fragments i think if hal were here he'd 1298 00:23:38,710 --> 00:23:38,720 fragments i think if hal were here he'd 1299 00:23:38,720 --> 00:23:40,789 fragments i think if hal were here he'd probably say that this was three three 1300 00:23:40,789 --> 00:23:40,799 probably say that this was three three 1301 00:23:40,799 --> 00:23:42,310 probably say that this was three three kilometer body 1302 00:23:42,310 --> 00:23:42,320 kilometer body 1303 00:23:42,320 --> 00:23:44,789 kilometer body i i would say the height of the plume 1304 00:23:44,789 --> 00:23:44,799 i i would say the height of the plume 1305 00:23:44,799 --> 00:23:45,750 i i would say the height of the plume now 1306 00:23:45,750 --> 00:23:45,760 now 1307 00:23:45,760 --> 00:23:47,669 now based on the modeling that we've done 1308 00:23:47,669 --> 00:23:47,679 based on the modeling that we've done 1309 00:23:47,679 --> 00:23:50,149 based on the modeling that we've done for a one kilometer impactor is 1310 00:23:50,149 --> 00:23:50,159 for a one kilometer impactor is 1311 00:23:50,159 --> 00:23:52,710 for a one kilometer impactor is consistent with that in other words 1312 00:23:52,710 --> 00:23:52,720 consistent with that in other words 1313 00:23:52,720 --> 00:23:54,950 consistent with that in other words you know that that that estimate by hal 1314 00:23:54,950 --> 00:23:54,960 you know that that that estimate by hal 1315 00:23:54,960 --> 00:23:56,950 you know that that that estimate by hal weaver for of three kilometers looks 1316 00:23:56,950 --> 00:23:56,960 weaver for of three kilometers looks 1317 00:23:56,960 --> 00:24:00,070 weaver for of three kilometers looks looks pretty golden to me 1318 00:24:00,070 --> 00:24:00,080 looks pretty golden to me 1319 00:24:00,080 --> 00:24:02,549 looks pretty golden to me uh universal time right eastern daylight 1320 00:24:02,549 --> 00:24:02,559 uh universal time right eastern daylight 1321 00:24:02,559 --> 00:24:06,710 uh universal time right eastern daylight time that was uh subtract four hours 1322 00:24:06,710 --> 00:24:06,720 time that was uh subtract four hours 1323 00:24:06,720 --> 00:24:11,029 time that was uh subtract four hours early in the morning very early 1324 00:24:11,029 --> 00:24:11,039 1325 00:24:11,039 --> 00:24:12,789 okay can we take a question in the far 1326 00:24:12,789 --> 00:24:12,799 okay can we take a question in the far 1327 00:24:12,799 --> 00:24:18,310 okay can we take a question in the far corner and the back there please 1328 00:24:18,310 --> 00:24:18,320 1329 00:24:18,320 --> 00:24:20,950 jim reston for esquire i have two 1330 00:24:20,950 --> 00:24:20,960 jim reston for esquire i have two 1331 00:24:20,960 --> 00:24:23,590 jim reston for esquire i have two questions if you could see the full 1332 00:24:23,590 --> 00:24:23,600 questions if you could see the full 1333 00:24:23,600 --> 00:24:26,470 questions if you could see the full plume without the shadow 1334 00:24:26,470 --> 00:24:26,480 plume without the shadow 1335 00:24:26,480 --> 00:24:27,830 plume without the shadow would it mimic 1336 00:24:27,830 --> 00:24:27,840 would it mimic 1337 00:24:27,840 --> 00:24:28,789 would it mimic the 1338 00:24:28,789 --> 00:24:28,799 the 1339 00:24:28,799 --> 00:24:33,750 the fireball of hiroshima 1340 00:24:33,750 --> 00:24:33,760 1341 00:24:33,760 --> 00:24:35,190 we don't think so 1342 00:24:35,190 --> 00:24:35,200 we don't think so 1343 00:24:35,200 --> 00:24:38,470 we don't think so no what happens in this case is that 1344 00:24:38,470 --> 00:24:38,480 no what happens in this case is that 1345 00:24:38,480 --> 00:24:40,950 no what happens in this case is that the plume is erupting from substantial 1346 00:24:40,950 --> 00:24:40,960 the plume is erupting from substantial 1347 00:24:40,960 --> 00:24:42,310 the plume is erupting from substantial depth 1348 00:24:42,310 --> 00:24:42,320 depth 1349 00:24:42,320 --> 00:24:44,630 depth uh and so there is a column that goes 1350 00:24:44,630 --> 00:24:44,640 uh and so there is a column that goes 1351 00:24:44,640 --> 00:24:46,470 uh and so there is a column that goes down below the cloud tops that you don't 1352 00:24:46,470 --> 00:24:46,480 down below the cloud tops that you don't 1353 00:24:46,480 --> 00:24:48,870 down below the cloud tops that you don't see but what we see at the surface is 1354 00:24:48,870 --> 00:24:48,880 see but what we see at the surface is 1355 00:24:48,880 --> 00:24:51,029 see but what we see at the surface is just this big bump that comes up 1356 00:24:51,029 --> 00:24:51,039 just this big bump that comes up 1357 00:24:51,039 --> 00:24:53,909 just this big bump that comes up initially now as it flattens out it will 1358 00:24:53,909 --> 00:24:53,919 initially now as it flattens out it will 1359 00:24:53,919 --> 00:24:56,310 initially now as it flattens out it will kind of get kind of mushroom mushroomy 1360 00:24:56,310 --> 00:24:56,320 kind of get kind of mushroom mushroomy 1361 00:24:56,320 --> 00:24:59,110 kind of get kind of mushroom mushroomy out at the edges so that there is a gap 1362 00:24:59,110 --> 00:24:59,120 out at the edges so that there is a gap 1363 00:24:59,120 --> 00:25:01,669 out at the edges so that there is a gap between the bottom of that 1364 00:25:01,669 --> 00:25:01,679 between the bottom of that 1365 00:25:01,679 --> 00:25:04,789 between the bottom of that and the and the ammonia cloud deck 1366 00:25:04,789 --> 00:25:04,799 and the and the ammonia cloud deck 1367 00:25:04,799 --> 00:25:06,630 and the and the ammonia cloud deck and you can really in fact you could i 1368 00:25:06,630 --> 00:25:06,640 and you can really in fact you could i 1369 00:25:06,640 --> 00:25:08,390 and you can really in fact you could i think you could actually see that it's 1370 00:25:08,390 --> 00:25:08,400 think you could actually see that it's 1371 00:25:08,400 --> 00:25:11,029 think you could actually see that it's very high that pancake's very high up as 1372 00:25:11,029 --> 00:25:11,039 very high that pancake's very high up as 1373 00:25:11,039 --> 00:25:13,750 very high that pancake's very high up as you saw in that last frame and if also 1374 00:25:13,750 --> 00:25:13,760 you saw in that last frame and if also 1375 00:25:13,760 --> 00:25:15,590 you saw in that last frame and if also we noticed that the plume was somewhat 1376 00:25:15,590 --> 00:25:15,600 we noticed that the plume was somewhat 1377 00:25:15,600 --> 00:25:18,070 we noticed that the plume was somewhat asymmetric and i think that's because 1378 00:25:18,070 --> 00:25:18,080 asymmetric and i think that's because 1379 00:25:18,080 --> 00:25:20,149 asymmetric and i think that's because this is a directional 1380 00:25:20,149 --> 00:25:20,159 this is a directional 1381 00:25:20,159 --> 00:25:22,630 this is a directional thing this this this thing the comet 1382 00:25:22,630 --> 00:25:22,640 thing this this this thing the comet 1383 00:25:22,640 --> 00:25:25,029 thing this this this thing the comet pieces are not coming straight down onto 1384 00:25:25,029 --> 00:25:25,039 pieces are not coming straight down onto 1385 00:25:25,039 --> 00:25:27,110 pieces are not coming straight down onto the atmosphere they're coming in at some 1386 00:25:27,110 --> 00:25:27,120 the atmosphere they're coming in at some 1387 00:25:27,120 --> 00:25:29,269 the atmosphere they're coming in at some angle and 1388 00:25:29,269 --> 00:25:29,279 angle and 1389 00:25:29,279 --> 00:25:31,029 angle and so in that sense it's a very different 1390 00:25:31,029 --> 00:25:31,039 so in that sense it's a very different 1391 00:25:31,039 --> 00:25:33,669 so in that sense it's a very different kind of morphology different shape and 1392 00:25:33,669 --> 00:25:33,679 kind of morphology different shape and 1393 00:25:33,679 --> 00:25:35,669 kind of morphology different shape and also in the little scenario i sketched 1394 00:25:35,669 --> 00:25:35,679 also in the little scenario i sketched 1395 00:25:35,679 --> 00:25:37,750 also in the little scenario i sketched for you earlier um the plume doesn't 1396 00:25:37,750 --> 00:25:37,760 for you earlier um the plume doesn't 1397 00:25:37,760 --> 00:25:39,909 for you earlier um the plume doesn't really necessarily rise straight up it 1398 00:25:39,909 --> 00:25:39,919 really necessarily rise straight up it 1399 00:25:39,919 --> 00:25:42,549 really necessarily rise straight up it might come out that too blows outside it 1400 00:25:42,549 --> 00:25:42,559 might come out that too blows outside it 1401 00:25:42,559 --> 00:25:44,710 might come out that too blows outside it blows out sideways 1402 00:25:44,710 --> 00:25:44,720 blows out sideways 1403 00:25:44,720 --> 00:25:46,070 blows out sideways maybe 1404 00:25:46,070 --> 00:25:46,080 maybe 1405 00:25:46,080 --> 00:25:49,029 maybe the second question is 1406 00:25:49,029 --> 00:25:49,039 the second question is 1407 00:25:49,039 --> 00:25:51,190 the second question is when these three 1408 00:25:51,190 --> 00:25:51,200 when these three 1409 00:25:51,200 --> 00:25:53,669 when these three fragments hit in the same location q r 1410 00:25:53,669 --> 00:25:53,679 fragments hit in the same location q r 1411 00:25:53,679 --> 00:25:56,230 fragments hit in the same location q r and s does that increase the chances of 1412 00:25:56,230 --> 00:25:56,240 and s does that increase the chances of 1413 00:25:56,240 --> 00:25:57,830 and s does that increase the chances of a cyclone effect 1414 00:25:57,830 --> 00:25:57,840 a cyclone effect 1415 00:25:57,840 --> 00:25:59,669 a cyclone effect or an anticyclone that could be 1416 00:25:59,669 --> 00:25:59,679 or an anticyclone that could be 1417 00:25:59,679 --> 00:26:01,750 or an anticyclone that could be permanent i'll tell you the answer to 1418 00:26:01,750 --> 00:26:01,760 permanent i'll tell you the answer to 1419 00:26:01,760 --> 00:26:04,710 permanent i'll tell you the answer to that in about two or three days 1420 00:26:04,710 --> 00:26:04,720 that in about two or three days 1421 00:26:04,720 --> 00:26:06,630 that in about two or three days after it happens 1422 00:26:06,630 --> 00:26:06,640 after it happens 1423 00:26:06,640 --> 00:26:10,070 after it happens it does increase it or it has no effect 1424 00:26:10,070 --> 00:26:10,080 it does increase it or it has no effect 1425 00:26:10,080 --> 00:26:12,230 it does increase it or it has no effect i really can't even speculate at this 1426 00:26:12,230 --> 00:26:12,240 i really can't even speculate at this 1427 00:26:12,240 --> 00:26:13,990 i really can't even speculate at this point none of this stuff is something 1428 00:26:13,990 --> 00:26:14,000 point none of this stuff is something 1429 00:26:14,000 --> 00:26:16,230 point none of this stuff is something that that we had expected to really see 1430 00:26:16,230 --> 00:26:16,240 that that we had expected to really see 1431 00:26:16,240 --> 00:26:16,950 that that we had expected to really see so 1432 00:26:16,950 --> 00:26:16,960 so 1433 00:26:16,960 --> 00:26:19,350 so um we're we're moving well into the 1434 00:26:19,350 --> 00:26:19,360 um we're we're moving well into the 1435 00:26:19,360 --> 00:26:21,350 um we're we're moving well into the realm of speculation certainly it's 1436 00:26:21,350 --> 00:26:21,360 realm of speculation certainly it's 1437 00:26:21,360 --> 00:26:23,269 realm of speculation certainly it's going to disturb the atmosphere a lot 1438 00:26:23,269 --> 00:26:23,279 going to disturb the atmosphere a lot 1439 00:26:23,279 --> 00:26:25,990 going to disturb the atmosphere a lot more than a single impact on one site 1440 00:26:25,990 --> 00:26:26,000 more than a single impact on one site 1441 00:26:26,000 --> 00:26:27,029 more than a single impact on one site would 1442 00:26:27,029 --> 00:26:27,039 would 1443 00:26:27,039 --> 00:26:29,750 would i won't go much further than that though 1444 00:26:29,750 --> 00:26:29,760 i won't go much further than that though 1445 00:26:29,760 --> 00:26:31,830 i won't go much further than that though okay we've got uh we've got time for one 1446 00:26:31,830 --> 00:26:31,840 okay we've got uh we've got time for one 1447 00:26:31,840 --> 00:26:33,269 okay we've got uh we've got time for one more question before we go to the jet 1448 00:26:33,269 --> 00:26:33,279 more question before we go to the jet 1449 00:26:33,279 --> 00:26:35,669 more question before we go to the jet propulsion laboratory 1450 00:26:35,669 --> 00:26:35,679 propulsion laboratory 1451 00:26:35,679 --> 00:26:40,789 propulsion laboratory we'll take a question from right here 1452 00:26:40,789 --> 00:26:40,799 1453 00:26:40,799 --> 00:26:43,590 an automotive kyodo news service uh i 1454 00:26:43,590 --> 00:26:43,600 an automotive kyodo news service uh i 1455 00:26:43,600 --> 00:26:46,630 an automotive kyodo news service uh i heard that japanese radio astronomers 1456 00:26:46,630 --> 00:26:46,640 heard that japanese radio astronomers 1457 00:26:46,640 --> 00:26:48,230 heard that japanese radio astronomers reported that 1458 00:26:48,230 --> 00:26:48,240 reported that 1459 00:26:48,240 --> 00:26:49,430 reported that they 1460 00:26:49,430 --> 00:26:49,440 they 1461 00:26:49,440 --> 00:26:50,310 they had 1462 00:26:50,310 --> 00:26:50,320 had 1463 00:26:50,320 --> 00:26:51,269 had seen 1464 00:26:51,269 --> 00:26:51,279 seen 1465 00:26:51,279 --> 00:26:55,110 seen some something which indicates that 1466 00:26:55,110 --> 00:26:55,120 some something which indicates that 1467 00:26:55,120 --> 00:26:58,789 some something which indicates that the fragment broke into two pieces uh 1468 00:26:58,789 --> 00:26:58,799 the fragment broke into two pieces uh 1469 00:26:58,799 --> 00:27:01,510 the fragment broke into two pieces uh before impact and i'm wondering whether 1470 00:27:01,510 --> 00:27:01,520 before impact and i'm wondering whether 1471 00:27:01,520 --> 00:27:03,590 before impact and i'm wondering whether the irregular shape 1472 00:27:03,590 --> 00:27:03,600 the irregular shape 1473 00:27:03,600 --> 00:27:05,510 the irregular shape has something to do with that would you 1474 00:27:05,510 --> 00:27:05,520 has something to do with that would you 1475 00:27:05,520 --> 00:27:06,870 has something to do with that would you comment on that 1476 00:27:06,870 --> 00:27:06,880 comment on that 1477 00:27:06,880 --> 00:27:09,110 comment on that i saw a report on the internet about 1478 00:27:09,110 --> 00:27:09,120 i saw a report on the internet about 1479 00:27:09,120 --> 00:27:13,190 i saw a report on the internet about some unusual radio signals and 1480 00:27:13,190 --> 00:27:13,200 some unusual radio signals and 1481 00:27:13,200 --> 00:27:15,350 some unusual radio signals and all i can say to that is that the 1482 00:27:15,350 --> 00:27:15,360 all i can say to that is that the 1483 00:27:15,360 --> 00:27:18,230 all i can say to that is that the signature of this impact the g 1484 00:27:18,230 --> 00:27:18,240 signature of this impact the g 1485 00:27:18,240 --> 00:27:22,070 signature of this impact the g is very very similar to that scene for a 1486 00:27:22,070 --> 00:27:22,080 is very very similar to that scene for a 1487 00:27:22,080 --> 00:27:24,470 is very very similar to that scene for a c and e the ones that we have good 1488 00:27:24,470 --> 00:27:24,480 c and e the ones that we have good 1489 00:27:24,480 --> 00:27:27,430 c and e the ones that we have good images of so far does not appear to be 1490 00:27:27,430 --> 00:27:27,440 images of so far does not appear to be 1491 00:27:27,440 --> 00:27:30,390 images of so far does not appear to be anything other than a solid single 1492 00:27:30,390 --> 00:27:30,400 anything other than a solid single 1493 00:27:30,400 --> 00:27:33,750 anything other than a solid single main body or explosion or rubber rubble 1494 00:27:33,750 --> 00:27:33,760 main body or explosion or rubber rubble 1495 00:27:33,760 --> 00:27:36,870 main body or explosion or rubber rubble pile it seems to be only one that i i 1496 00:27:36,870 --> 00:27:36,880 pile it seems to be only one that i i 1497 00:27:36,880 --> 00:27:38,070 pile it seems to be only one that i i wanted to make sure to mention that 1498 00:27:38,070 --> 00:27:38,080 wanted to make sure to mention that 1499 00:27:38,080 --> 00:27:40,230 wanted to make sure to mention that other site nearby to make sure that you 1500 00:27:40,230 --> 00:27:40,240 other site nearby to make sure that you 1501 00:27:40,240 --> 00:27:41,990 other site nearby to make sure that you understood that that was an old impact 1502 00:27:41,990 --> 00:27:42,000 understood that that was an old impact 1503 00:27:42,000 --> 00:27:44,470 understood that that was an old impact site that it was not related to g 1504 00:27:44,470 --> 00:27:44,480 site that it was not related to g 1505 00:27:44,480 --> 00:27:46,789 site that it was not related to g so it doesn't look like a double one 1506 00:27:46,789 --> 00:27:46,799 so it doesn't look like a double one 1507 00:27:46,799 --> 00:27:48,390 so it doesn't look like a double one from these images 1508 00:27:48,390 --> 00:27:48,400 from these images 1509 00:27:48,400 --> 00:27:49,510 from these images okay we're going to go to the jet 1510 00:27:49,510 --> 00:27:49,520 okay we're going to go to the jet 1511 00:27:49,520 --> 00:27:51,909 okay we're going to go to the jet propulsion laboratory now 1512 00:27:51,909 -->

host of the los angeles times 1532 00:28:19,110 --> 00:28:19,120 robert lee host of the los angeles times 1533 00:28:19,120 --> 00:28:20,630 robert lee host of the los angeles times uh you mentioned a moment ago that you 1534 00:28:20,630 --> 00:28:20,640 uh you mentioned a moment ago that you 1535 00:28:20,640 --> 00:28:22,549 uh you mentioned a moment ago that you had some actual numbers 1536 00:28:22,549 --> 00:28:22,559 had some actual numbers 1537 00:28:22,559 --> 00:28:25,190 had some actual numbers on the uh estimated sizes of the spot 1538 00:28:25,190 --> 00:28:25,200 on the uh estimated sizes of the spot 1539 00:28:25,200 --> 00:28:27,029 on the uh estimated sizes of the spot and the ring and the smudge 1540 00:28:27,029 --> 00:28:27,039 and the ring and the smudge 1541 00:28:27,039 --> 00:28:28,710 and the ring and the smudge uh i wonder if we could hear those 1542 00:28:28,710 --> 00:28:28,720 uh i wonder if we could hear those 1543 00:28:28,720 --> 00:28:30,070 uh i wonder if we could hear those numbers and then i have two quick 1544 00:28:30,070 --> 00:28:30,080 numbers and then i have two quick 1545 00:28:30,080 --> 00:28:31,909 numbers and then i have two quick follow-ups 1546 00:28:31,909 --> 00:28:31,919 follow-ups 1547 00:28:31,919 --> 00:28:33,430 follow-ups all right these are very very 1548 00:28:33,430 --> 00:28:33,440 all right these are very very 1549 00:28:33,440 --> 00:28:35,750 all right these are very very preliminary preliminary we haven't had 1550 00:28:35,750 --> 00:28:35,760 preliminary preliminary we haven't had 1551 00:28:35,760 --> 00:28:38,870 preliminary preliminary we haven't had much time to do detailed analysis 1552 00:28:38,870 --> 00:28:38,880 much time to do detailed analysis 1553 00:28:38,880 --> 00:28:42,230 much time to do detailed analysis for our first cut analysis the diameter 1554 00:28:42,230 --> 00:28:42,240 for our first cut analysis the diameter 1555 00:28:42,240 --> 00:28:44,470 for our first cut analysis the diameter of the black ring and if you show the 1556 00:28:44,470 --> 00:28:44,480 of the black ring and if you show the 1557 00:28:44,480 --> 00:28:46,310 of the black ring and if you show the blow up version they'll have a better 1558 00:28:46,310 --> 00:28:46,320 blow up version they'll have a better 1559 00:28:46,320 --> 00:28:48,310 blow up version they'll have a better idea of what i'm talking about 1560 00:28:48,310 --> 00:28:48,320 idea of what i'm talking about 1561 00:28:48,320 --> 00:28:50,070 idea of what i'm talking about or the white ring if you have a methane 1562 00:28:50,070 --> 00:28:50,080 or the white ring if you have a methane 1563 00:28:50,080 --> 00:28:52,070 or the white ring if you have a methane image available 1564 00:28:52,070 --> 00:28:52,080 image available 1565 00:28:52,080 --> 00:28:55,830 image available the diameter of that sharp thin ring is 1566 00:28:55,830 --> 00:28:55,840 the diameter of that sharp thin ring is 1567 00:28:55,840 --> 00:28:59,190 the diameter of that sharp thin ring is about 7 500 kilometers 1568 00:28:59,190 --> 00:28:59,200 about 7 500 kilometers 1569 00:28:59,200 --> 00:28:59,990 about 7 500 kilometers and 1570 00:28:59,990 --> 00:29:00,000 and 1571 00:29:00,000 --> 00:29:02,389 and the diameter of the 1572 00:29:02,389 --> 00:29:02,399 the diameter of the 1573 00:29:02,399 --> 00:29:03,350 the diameter of the white 1574 00:29:03,350 --> 00:29:03,360 white 1575 00:29:03,360 --> 00:29:07,350 white ring surrounding that the inside of the 1576 00:29:07,350 --> 00:29:07,360 ring surrounding that the inside of the 1577 00:29:07,360 --> 00:29:10,470 ring surrounding that the inside of the black eye as it were that's about 1578 00:29:10,470 --> 00:29:10,480 black eye as it were that's about 1579 00:29:10,480 --> 00:29:12,789 black eye as it were that's about 15 thousand four hundred and fifty 1580 00:29:12,789 --> 00:29:12,799 15 thousand four hundred and fifty 1581 00:29:12,799 --> 00:29:17,110 15 thousand four hundred and fifty kilometers 1582 00:29:17,110 --> 00:29:17,120 1583 00:29:17,120 --> 00:29:19,510 are there any other questions yes 1584 00:29:19,510 --> 00:29:19,520 are there any other questions yes 1585 00:29:19,520 --> 00:29:22,630 are there any other questions yes just two quick uh follow-ups um 1586 00:29:22,630 --> 00:29:22,640 just two quick uh follow-ups um 1587 00:29:22,640 --> 00:29:24,389 just two quick uh follow-ups um i wonder uh 1588 00:29:24,389 --> 00:29:24,399 i wonder uh 1589 00:29:24,399 --> 00:29:25,909 i wonder uh and perhaps this is for gene shoemaker 1590 00:29:25,909 --> 00:29:25,919 and perhaps this is for gene shoemaker 1591 00:29:25,919 --> 00:29:27,510 and perhaps this is for gene shoemaker if you could compare 1592 00:29:27,510 --> 00:29:27,520 if you could compare 1593 00:29:27,520 --> 00:29:31,110 if you could compare uh in your mind the uh size and energy 1594 00:29:31,110 --> 00:29:31,120 uh in your mind the uh size and energy 1595 00:29:31,120 --> 00:29:32,070 uh in your mind the uh size and energy of this 1596 00:29:32,070 --> 00:29:32,080 of this 1597 00:29:32,080 --> 00:29:34,389 of this fragment to the object that is believed 1598 00:29:34,389 --> 00:29:34,399 fragment to the object that is believed 1599 00:29:34,399 --> 00:29:37,430 fragment to the object that is believed to have caused the chixel upgrader 1600 00:29:37,430 --> 00:29:37,440 to have caused the chixel upgrader 1601 00:29:37,440 --> 00:29:40,230 to have caused the chixel upgrader okay the minimum size of the chigzelub 1602 00:29:40,230 --> 00:29:40,240 okay the minimum size of the chigzelub 1603 00:29:40,240 --> 00:29:41,909 okay the minimum size of the chigzelub crater and it's still a matter of 1604 00:29:41,909 --> 00:29:41,919 crater and it's still a matter of 1605 00:29:41,919 --> 00:29:44,789 crater and it's still a matter of controversy the full crater i prefer the 1606 00:29:44,789 --> 00:29:44,799 controversy the full crater i prefer the 1607 00:29:44,799 --> 00:29:47,269 controversy the full crater i prefer the to use the minimum value which is about 1608 00:29:47,269 --> 00:29:47,279 to use the minimum value which is about 1609 00:29:47,279 --> 00:29:50,470 to use the minimum value which is about 180 kilometers in diameter 1610 00:29:50,470 --> 00:29:50,480 180 kilometers in diameter 1611 00:29:50,480 --> 00:29:53,110 180 kilometers in diameter so we're talking about something that's 1612 00:29:53,110 --> 00:29:53,120 so we're talking about something that's 1613 00:29:53,120 --> 00:29:56,149 so we're talking about something that's uh three times smaller 1614 00:29:56,149 --> 00:29:56,159 uh three times smaller 1615 00:29:56,159 --> 00:29:58,230 uh three times smaller and the energy 1616 00:29:58,230 --> 00:29:58,240 and the energy 1617 00:29:58,240 --> 00:30:03,110 and the energy here then is 27 roughly about 27 times 1618 00:30:03,110 --> 00:30:03,120 here then is 27 roughly about 27 times 1619 00:30:03,120 --> 00:30:04,630 here then is 27 roughly about 27 times less 1620 00:30:04,630 --> 00:30:04,640 less 1621 00:30:04,640 --> 00:30:05,990 less so this is uh 1622 00:30:05,990 --> 00:30:06,000 so this is uh 1623 00:30:06,000 --> 00:30:08,789 so this is uh this is a big event uh but it still 1624 00:30:08,789 --> 00:30:08,799 this is a big event uh but it still 1625 00:30:08,799 --> 00:30:12,310 this is a big event uh but it still isn't the dinosaur killer 1626 00:30:12,310 --> 00:30:12,320 1627 00:30:12,320 --> 00:30:14,870 do we have any more questions from jpl 1628 00:30:14,870 --> 00:30:14,880 do we have any more questions from jpl 1629 00:30:14,880 --> 00:30:17,190 do we have any more questions from jpl for us the level of uh internet email 1630 00:30:17,190 --> 00:30:17,200 for us the level of uh internet email 1631 00:30:17,200 --> 00:30:19,110 for us the level of uh internet email traffic that you're seeing how crowded 1632 00:30:19,110 --> 00:30:19,120 traffic that you're seeing how crowded 1633 00:30:19,120 --> 00:30:23,350 traffic that you're seeing how crowded is the electronic huddle 1634 00:30:23,350 --> 00:30:23,360 1635 00:30:23,360 --> 00:30:24,470 well 1636 00:30:24,470 --> 00:30:24,480 well 1637 00:30:24,480 --> 00:30:27,430 well we have a a an email distribution 1638 00:30:27,430 --> 00:30:27,440 we have a a an email distribution 1639 00:30:27,440 --> 00:30:29,350 we have a a an email distribution network set up for the professional 1640 00:30:29,350 --> 00:30:29,360 network set up for the professional 1641 00:30:29,360 --> 00:30:31,430 network set up for the professional astronomy community and that is actually 1642 00:30:31,430 --> 00:30:31,440 astronomy community and that is actually 1643 00:30:31,440 --> 00:30:33,990 astronomy community and that is actually working extraordinarily well people are 1644 00:30:33,990 --> 00:30:34,000 working extraordinarily well people are 1645 00:30:34,000 --> 00:30:36,549 working extraordinarily well people are being very concise about reporting their 1646 00:30:36,549 --> 00:30:36,559 being very concise about reporting their 1647 00:30:36,559 --> 00:30:39,430 being very concise about reporting their observations and therefore we are we 1648 00:30:39,430 --> 00:30:39,440 observations and therefore we are we 1649 00:30:39,440 --> 00:30:42,630 observations and therefore we are we have in our parlance very high signal to 1650 00:30:42,630 --> 00:30:42,640 have in our parlance very high signal to 1651 00:30:42,640 --> 00:30:44,070 have in our parlance very high signal to noise 1652 00:30:44,070 --> 00:30:44,080 noise 1653 00:30:44,080 --> 00:30:45,590 noise a very good amount of information is 1654 00:30:45,590 --> 00:30:45,600 a very good amount of information is 1655 00:30:45,600 --> 00:30:47,269 a very good amount of information is coming through 1656 00:30:47,269 --> 00:30:47,279 coming through 1657 00:30:47,279 --> 00:30:49,590 coming through i when i saw there this morning that 1658 00:30:49,590 --> 00:30:49,600 i when i saw there this morning that 1659 00:30:49,600 --> 00:30:51,350 i when i saw there this morning that that one of the um 1660 00:30:51,350 --> 00:30:51,360 that one of the um 1661 00:30:51,360 --> 00:30:53,830 that one of the um images from the irtf showing the g 1662 00:30:53,830 --> 00:30:53,840 images from the irtf showing the g 1663 00:30:53,840 --> 00:30:56,630 images from the irtf showing the g impact plume was posted on one of the 1664 00:30:56,630 --> 00:30:56,640 impact plume was posted on one of the 1665 00:30:56,640 --> 00:30:59,190 impact plume was posted on one of the mosaic bulletin boards i tried to 1666 00:30:59,190 --> 00:30:59,200 mosaic bulletin boards i tried to 1667 00:30:59,200 --> 00:31:01,909 mosaic bulletin boards i tried to connect and i could not get through and 1668 00:31:01,909 --> 00:31:01,919 connect and i could not get through and 1669 00:31:01,919 --> 00:31:03,750 connect and i could not get through and they said that there was so much traffic 1670 00:31:03,750 --> 00:31:03,760 they said that there was so much traffic 1671 00:31:03,760 --> 00:31:05,909 they said that there was so much traffic um on the networks trying to reach some 1672 00:31:05,909 --> 00:31:05,919 um on the networks trying to reach some 1673 00:31:05,919 --> 00:31:08,470 um on the networks trying to reach some of these very popular sites that that uh 1674 00:31:08,470 --> 00:31:08,480 of these very popular sites that that uh 1675 00:31:08,480 --> 00:31:09,990 of these very popular sites that that uh you know things are getting there 1676 00:31:09,990 --> 00:31:10,000 you know things are getting there 1677 00:31:10,000 --> 00:31:12,070 you know things are getting there there's a big traffic jam on the 1678 00:31:12,070 --> 00:31:12,080 there's a big traffic jam on the 1679 00:31:12,080 --> 00:31:14,070 there's a big traffic jam on the information super highway right now but 1680 00:31:14,070 --> 00:31:14,080 information super highway right now but 1681 00:31:14,080 --> 00:31:15,669 information super highway right now but this is an extraordinary event i think 1682 00:31:15,669 --> 00:31:15,679 this is an extraordinary event i think 1683 00:31:15,679 --> 00:31:17,269 this is an extraordinary event i think that's why normally we don't have that 1684 00:31:17,269 --> 00:31:17,279 that's why normally we don't have that 1685 00:31:17,279 --> 00:31:21,590 that's why normally we don't have that kind of difficulty 1686 00:31:21,590 --> 00:31:21,600 1687 00:31:21,600 --> 00:31:23,510 are there any more questions from jpm 1688 00:31:23,510 --> 00:31:23,520 are there any more questions from jpm 1689 00:31:23,520 --> 00:31:26,389 are there any more questions from jpm blackburn kcop tv in los angeles are you 1690 00:31:26,389 --> 00:31:26,399 blackburn kcop tv in los angeles are you 1691 00:31:26,399 --> 00:31:27,590 blackburn kcop tv in los angeles are you getting any 1692 00:31:27,590 --> 00:31:27,600 getting any 1693 00:31:27,600 --> 00:31:29,590 getting any readings yet to tell you the depth to 1694 00:31:29,590 --> 00:31:29,600 readings yet to tell you the depth to 1695 00:31:29,600 --> 00:31:31,430 readings yet to tell you the depth to which these 1696 00:31:31,430 --> 00:31:31,440 which these 1697 00:31:31,440 --> 00:31:33,750 which these impacts are going and or does it look 1698 00:31:33,750 --> 00:31:33,760 impacts are going and or does it look 1699 00:31:33,760 --> 00:31:35,110 impacts are going and or does it look pretty much as though it's staying very 1700 00:31:35,110 --> 00:31:35,120 pretty much as though it's staying very 1701 00:31:35,120 --> 00:31:38,070 pretty much as though it's staying very high in the atmosphere of jupiter 1702 00:31:38,070 --> 00:31:38,080 high in the atmosphere of jupiter 1703 00:31:38,080 --> 00:31:39,509 high in the atmosphere of jupiter i don't think we have a good answer for 1704 00:31:39,509 --> 00:31:39,519 i don't think we have a good answer for 1705 00:31:39,519 --> 00:31:41,509 i don't think we have a good answer for that question yet we're working on that 1706 00:31:41,509 --> 00:31:41,519 that question yet we're working on that 1707 00:31:41,519 --> 00:31:43,669 that question yet we're working on that that kind of a question 1708 00:31:43,669 --> 00:31:43,679 that kind of a question 1709 00:31:43,679 --> 00:31:45,110 that kind of a question you know we know something more about 1710 00:31:45,110 --> 00:31:45,120 you know we know something more about 1711 00:31:45,120 --> 00:31:46,549 you know we know something more about the heights because we can see them 1712 00:31:46,549 --> 00:31:46,559 the heights because we can see them 1713 00:31:46,559 --> 00:31:48,310 the heights because we can see them sticking away from jupiter it's awfully 1714 00:31:48,310 --> 00:31:48,320 sticking away from jupiter it's awfully 1715 00:31:48,320 --> 00:31:50,470 sticking away from jupiter it's awfully hard to know about probing deep 1716 00:31:50,470 --> 00:31:50,480 hard to know about probing deep 1717 00:31:50,480 --> 00:31:53,750 hard to know about probing deep one thing that will tell us for sure 1718 00:31:53,750 --> 00:31:53,760 one thing that will tell us for sure 1719 00:31:53,760 --> 00:31:55,590 one thing that will tell us for sure is some spectroscopy that's being 1720 00:31:55,590 --> 00:31:55,600 is some spectroscopy that's being 1721 00:31:55,600 --> 00:31:57,269 is some spectroscopy that's being planned by many telescopes around the 1722 00:31:57,269 --> 00:31:57,279 planned by many telescopes around the 1723 00:31:57,279 --> 00:31:59,990 planned by many telescopes around the world including the irtf including the 1724 00:31:59,990 --> 00:32:00,000 world including the irtf including the 1725 00:32:00,000 --> 00:32:02,310 world including the irtf including the kuiper airborne observatory and many 1726 00:32:02,310 --> 00:32:02,320 kuiper airborne observatory and many 1727 00:32:02,320 --> 00:32:04,950 kuiper airborne observatory and many others looking for water the signature 1728 00:32:04,950 --> 00:32:04,960 others looking for water the signature 1729 00:32:04,960 --> 00:32:07,350 others looking for water the signature of water if we see that 1730 00:32:07,350 --> 00:32:07,360 of water if we see that 1731 00:32:07,360 --> 00:32:09,029 of water if we see that then we will know 1732 00:32:09,029 --> 00:32:09,039 then we will know 1733 00:32:09,039 --> 00:32:10,149 then we will know how far 1734 00:32:10,149 --> 00:32:10,159 how far 1735 00:32:10,159 --> 00:32:12,070 how far at least that particular 1736 00:32:12,070 --> 00:32:12,080 at least that particular 1737 00:32:12,080 --> 00:32:14,070 at least that particular explosion went how far deep that 1738 00:32:14,070 --> 00:32:14,080 explosion went how far deep that 1739 00:32:14,080 --> 00:32:15,909 explosion went how far deep that impacting body went because we 1740 00:32:15,909 --> 00:32:15,919 impacting body went because we 1741 00:32:15,919 --> 00:32:18,230 impacting body went because we hypothesized the level at which the 1742 00:32:18,230 --> 00:32:18,240 hypothesized the level at which the 1743 00:32:18,240 --> 00:32:21,190 hypothesized the level at which the water clouds reside we can't see it it's 1744 00:32:21,190 --> 00:32:21,200 water clouds reside we can't see it it's 1745 00:32:21,200 --> 00:32:23,110 water clouds reside we can't see it it's below the visible cloud deck so that'll 1746 00:32:23,110 --> 00:32:23,120 below the visible cloud deck so that'll 1747 00:32:23,120 --> 00:32:26,070 below the visible cloud deck so that'll be a clue as to the depth it could be 1748 00:32:26,070 --> 00:32:26,080 be a clue as to the depth it could be 1749 00:32:26,080 --> 00:32:27,909 be a clue as to the depth it could be too that from these images we might be 1750 00:32:27,909 --> 00:32:27,919 too that from these images we might be 1751 00:32:27,919 --> 00:32:28,950 too that from these images we might be able to pull out some of this 1752 00:32:28,950 --> 00:32:28,960 able to pull out some of this 1753 00:32:28,960 --> 00:32:30,870 able to pull out some of this information that's going to take some 1754 00:32:30,870 --> 00:32:30,880 information that's going to take some 1755 00:32:30,880 --> 00:32:33,509 information that's going to take some very clever thinking on our part and on 1756 00:32:33,509 --> 00:32:33,519 very clever thinking on our part and on 1757 00:32:33,519 --> 00:32:36,230 very clever thinking on our part and on the part of the modelers to pull this 1758 00:32:36,230 --> 00:32:36,240 the part of the modelers to pull this 1759 00:32:36,240 --> 00:32:38,630 the part of the modelers to pull this all together and and make a coherent 1760 00:32:38,630 --> 00:32:38,640 all together and and make a coherent 1761 00:32:38,640 --> 00:32:41,509 all together and and make a coherent story i think we're still 1762 00:32:41,509 --> 00:32:41,519 story i think we're still 1763 00:32:41,519 --> 00:32:44,149 story i think we're still far too premature to be able to answer 1764 00:32:44,149 --> 00:32:44,159 far too premature to be able to answer 1765 00:32:44,159 --> 00:32:47,830 far too premature to be able to answer it with any certainty 1766 00:32:47,830 --> 00:32:47,840 1767 00:32:47,840 --> 00:32:50,470 walter richards of ktla los angeles i 1768 00:32:50,470 --> 00:32:50,480 walter richards of ktla los angeles i 1769 00:32:50,480 --> 00:32:52,470 walter richards of ktla los angeles i have two questions would anything be 1770 00:32:52,470 --> 00:32:52,480 have two questions would anything be 1771 00:32:52,480 --> 00:32:55,350 have two questions would anything be left of jupiter once this is all over 1772 00:32:55,350 --> 00:32:55,360 left of jupiter once this is all over 1773 00:32:55,360 --> 00:32:57,830 left of jupiter once this is all over and uh what impact 1774 00:32:57,830 --> 00:32:57,840 and uh what impact 1775 00:32:57,840 --> 00:32:59,909 and uh what impact would be what would the impact be on los 1776 00:32:59,909 --> 00:32:59,919 would be what would the impact be on los 1777 00:32:59,919 --> 00:33:03,990 would be what would the impact be on los angeles if it were hit 1778 00:33:03,990 --> 00:33:04,000 1779 00:33:04,000 --> 00:33:05,509 i i think jupiter is going to hang in 1780 00:33:05,509 --> 00:33:05,519 i i think jupiter is going to hang in 1781 00:33:05,519 --> 00:33:06,710 i i think jupiter is going to hang in there 1782 00:33:06,710 --> 00:33:06,720 there 1783 00:33:06,720 --> 00:33:08,789 there it's pretty big planet and we're seeing 1784 00:33:08,789 --> 00:33:08,799 it's pretty big planet and we're seeing 1785 00:33:08,799 --> 00:33:11,269 it's pretty big planet and we're seeing these these big splotches and black eyes 1786 00:33:11,269 --> 00:33:11,279 these these big splotches and black eyes 1787 00:33:11,279 --> 00:33:13,110 these these big splotches and black eyes and bruises i feel sorry for jupiter 1788 00:33:13,110 --> 00:33:13,120 and bruises i feel sorry for jupiter 1789 00:33:13,120 --> 00:33:15,269 and bruises i feel sorry for jupiter it's really getting pummeled but but i i 1790 00:33:15,269 --> 00:33:15,279 it's really getting pummeled but but i i 1791 00:33:15,279 --> 00:33:16,470 it's really getting pummeled but but i i think it's going to hang in there and 1792 00:33:16,470 --> 00:33:16,480 think it's going to hang in there and 1793 00:33:16,480 --> 00:33:19,029 think it's going to hang in there and the bruises will fade after some period 1794 00:33:19,029 --> 00:33:19,039 the bruises will fade after some period 1795 00:33:19,039 --> 00:33:21,830 the bruises will fade after some period of time which which we don't know yet 1796 00:33:21,830 --> 00:33:21,840 of time which which we don't know yet 1797 00:33:21,840 --> 00:33:23,509 of time which which we don't know yet i'll turn the los angeles question over 1798 00:33:23,509 --> 00:33:23,519 i'll turn the los angeles question over 1799 00:33:23,519 --> 00:33:28,549 i'll turn the los angeles question over to gene that being my native hometown 1800 00:33:28,549 --> 00:33:28,559 1801 00:33:28,559 --> 00:33:30,630 well if this 60 kilometer crater is the 1802 00:33:30,630 --> 00:33:30,640 well if this 60 kilometer crater is the 1803 00:33:30,640 --> 00:33:32,710 well if this 60 kilometer crater is the right estimate i think it's pretty good 1804 00:33:32,710 --> 00:33:32,720 right estimate i think it's pretty good 1805 00:33:32,720 --> 00:33:35,110 right estimate i think it's pretty good and you put a bullseye over 1806 00:33:35,110 --> 00:33:35,120 and you put a bullseye over 1807 00:33:35,120 --> 00:33:37,590 and you put a bullseye over city hall in los angeles that's going to 1808 00:33:37,590 --> 00:33:37,600 city hall in los angeles that's going to 1809 00:33:37,600 --> 00:33:40,549 city hall in los angeles that's going to take out everything in the crater 1810 00:33:40,549 --> 00:33:40,559 take out everything in the crater 1811 00:33:40,559 --> 00:33:43,350 take out everything in the crater it'll it'll take out all of la county 1812 00:33:43,350 --> 00:33:43,360 it'll it'll take out all of la county 1813 00:33:43,360 --> 00:33:45,190 it'll it'll take out all of la county and in fact i just wouldn't want to be 1814 00:33:45,190 --> 00:33:45,200 and in fact i just wouldn't want to be 1815 00:33:45,200 --> 00:33:51,350 and in fact i just wouldn't want to be in southern california period 1816 00:33:51,350 --> 00:33:51,360 1817 00:33:51,360 --> 00:33:52,950 okay if there are no more questions from

newspaper 1830 00:34:06,870 --> 00:34:06,880 science writer for japanese newspaper 1831 00:34:06,880 --> 00:34:08,950 science writer for japanese newspaper the yo miri shimbun i have questions 1832 00:34:08,950 --> 00:34:08,960 the yo miri shimbun i have questions 1833 00:34:08,960 --> 00:34:12,790 the yo miri shimbun i have questions about the impact energy of fragments 1834 00:34:12,790 --> 00:34:12,800 about the impact energy of fragments 1835 00:34:12,800 --> 00:34:17,109 about the impact energy of fragments as far as and i understand that 1836 00:34:17,109 --> 00:34:17,119 1837 00:34:17,119 --> 00:34:17,909 the 1838 00:34:17,909 --> 00:34:17,919 the 1839 00:34:17,919 --> 00:34:20,950 the impact energy is proportional to the 1840 00:34:20,950 --> 00:34:20,960 impact energy is proportional to the 1841 00:34:20,960 --> 00:34:22,790 impact energy is proportional to the cubit radius of 1842 00:34:22,790 --> 00:34:22,800 cubit radius of 1843 00:34:22,800 --> 00:34:25,750 cubit radius of a fragment when the impact velocity is 1844 00:34:25,750 --> 00:34:25,760 a fragment when the impact velocity is 1845 00:34:25,760 --> 00:34:28,629 a fragment when the impact velocity is the same is it all right 1846 00:34:28,629 --> 00:34:28,639 the same is it all right 1847 00:34:28,639 --> 00:34:30,470 the same is it all right yes that's right the impact energy is 1848 00:34:30,470 --> 00:34:30,480 yes that's right the impact energy is 1849 00:34:30,480 --> 00:34:32,550 yes that's right the impact energy is proportional the cube of the radius and 1850 00:34:32,550 --> 00:34:32,560 proportional the cube of the radius and 1851 00:34:32,560 --> 00:34:36,869 proportional the cube of the radius and to the square of the velocity 1852 00:34:36,869 --> 00:34:36,879 1853 00:34:36,879 --> 00:34:39,829 do you have the estimated 1854 00:34:39,829 --> 00:34:39,839 do you have the estimated 1855 00:34:39,839 --> 00:34:43,109 do you have the estimated figure of energy in terms of tnt 1856 00:34:43,109 --> 00:34:43,119 figure of energy in terms of tnt 1857 00:34:43,119 --> 00:34:45,750 figure of energy in terms of tnt which is caused by the 1858 00:34:45,750 --> 00:34:45,760 which is caused by the 1859 00:34:45,760 --> 00:34:47,510 which is caused by the impacts of all the 1860 00:34:47,510 --> 00:34:47,520 impacts of all the 1861 00:34:47,520 --> 00:34:50,069 impacts of all the all the fragments of the 1862 00:34:50,069 --> 00:34:50,079 all the fragments of the 1863 00:34:50,079 --> 00:34:52,950 all the fragments of the sl9 1864 00:34:52,950 --> 00:34:52,960 1865 00:34:52,960 --> 00:34:56,310 well you can start to add them up 1866 00:34:56,310 --> 00:34:56,320 well you can start to add them up 1867 00:34:56,320 --> 00:34:59,990 well you can start to add them up we've seen perhaps the biggest 1868 00:34:59,990 --> 00:35:00,000 we've seen perhaps the biggest 1869 00:35:00,000 --> 00:35:03,430 we've seen perhaps the biggest i'd multiply that by 1870 00:35:03,430 --> 00:35:03,440 i'd multiply that by 1871 00:35:03,440 --> 00:35:07,670 i'd multiply that by a factor of uh maybe six to eight 1872 00:35:07,670 --> 00:35:07,680 a factor of uh maybe six to eight 1873 00:35:07,680 --> 00:35:09,430 a factor of uh maybe six to eight might give us the total some somewhere 1874 00:35:09,430 --> 00:35:09,440 might give us the total some somewhere 1875 00:35:09,440 --> 00:35:10,950 might give us the total some somewhere in that ballpark 1876 00:35:10,950 --> 00:35:10,960 in that ballpark 1877 00:35:10,960 --> 00:35:13,670 in that ballpark so we're we're talking about something 1878 00:35:13,670 --> 00:35:13,680 so we're we're talking about something 1879 00:35:13,680 --> 00:35:15,109 so we're we're talking about something of the order 1880 00:35:15,109 --> 00:35:15,119 of the order 1881 00:35:15,119 --> 00:35:17,750 of the order of 40 million 1882 00:35:17,750 --> 00:35:17,760 of 40 million 1883 00:35:17,760 --> 00:35:19,510 of 40 million megatons perhaps 1884 00:35:19,510 --> 00:35:19,520 megatons perhaps 1885 00:35:19,520 --> 00:35:20,790 megatons perhaps of energy 1886 00:35:20,790 --> 00:35:20,800 of energy 1887 00:35:20,800 --> 00:35:22,470 of energy very rough ballpark 1888 00:35:22,470 --> 00:35:22,480 very rough ballpark 1889 00:35:22,480 --> 00:35:24,950 very rough ballpark give that a slosh of at least a factor 1890 00:35:24,950 --> 00:35:24,960 give that a slosh of at least a factor 1891 00:35:24,960 --> 00:35:28,069 give that a slosh of at least a factor of 10 million megatons either way or 1892 00:35:28,069 --> 00:35:28,079 of 10 million megatons either way or 1893 00:35:28,079 --> 00:35:29,990 of 10 million megatons either way or more because we you know we're just 1894 00:35:29,990 --> 00:35:30,000 more because we you know we're just 1895 00:35:30,000 --> 00:35:33,190 more because we you know we're just going on what we've seen so far 1896 00:35:33,190 --> 00:35:33,200 going on what we've seen so far 1897 00:35:33,200 --> 00:35:34,550 going on what we've seen so far okay we're going to leave marshall and 1898 00:35:34,550 --> 00:35:34,560 okay we're going to leave marshall and 1899 00:35:34,560 --> 00:35:36,310 okay we're going to leave marshall and come back here to goddard to take any 1900 00:35:36,310 --> 00:35:36,320 come back here to goddard to take any 1901 00:35:36,320 --> 00:35:43,589 come back here to goddard to take any more questions over here 1902 00:35:43,589 --> 00:35:43,599 1903 00:35:43,599 --> 00:35:45,510 um it's kind of an elementary school 1904 00:35:45,510 --> 00:35:45,520 um it's kind of an elementary school 1905 00:35:45,520 --> 00:35:46,630 um it's kind of an elementary school question but 1906 00:35:46,630 --> 00:35:46,640 question but 1907 00:35:46,640 --> 00:35:47,430 question but since 1908 00:35:47,430 --> 00:35:47,440 since 1909 00:35:47,440 --> 00:35:49,589 since um jupiter is so much more massive than 1910 00:35:49,589 --> 00:35:49,599 um jupiter is so much more massive than 1911 00:35:49,599 --> 00:35:50,550 um jupiter is so much more massive than earth 1912 00:35:50,550 --> 00:35:50,560 earth 1913 00:35:50,560 --> 00:35:52,390 earth and gravity is pulling these guys in 1914 00:35:52,390 --> 00:35:52,400 and gravity is pulling these guys in 1915 00:35:52,400 --> 00:35:53,910 and gravity is pulling these guys in therefore it's got a stronger stronger 1916 00:35:53,910 --> 00:35:53,920 therefore it's got a stronger stronger 1917 00:35:53,920 --> 00:35:55,270 therefore it's got a stronger stronger gravity 1918 00:35:55,270 --> 00:35:55,280 gravity 1919 00:35:55,280 --> 00:35:57,670 gravity wouldn't the comparable mass hit 1920 00:35:57,670 --> 00:35:57,680 wouldn't the comparable mass hit 1921 00:35:57,680 --> 00:35:59,349 wouldn't the comparable mass hit jupiter with greater 1922 00:35:59,349 --> 00:35:59,359 jupiter with greater 1923 00:35:59,359 --> 00:36:02,150 jupiter with greater velocity and therefore energy than than 1924 00:36:02,150 --> 00:36:02,160 velocity and therefore energy than than 1925 00:36:02,160 --> 00:36:05,589 velocity and therefore energy than than it would earth 1926 00:36:05,589 --> 00:36:05,599 1927 00:36:05,599 --> 00:36:07,430 if i understand your question is if you 1928 00:36:07,430 --> 00:36:07,440 if i understand your question is if you 1929 00:36:07,440 --> 00:36:09,510 if i understand your question is if you have the same mass 1930 00:36:09,510 --> 00:36:09,520 have the same mass 1931 00:36:09,520 --> 00:36:11,030 have the same mass one's falling in jupiter and one's 1932 00:36:11,030 --> 00:36:11,040 one's falling in jupiter and one's 1933 00:36:11,040 --> 00:36:12,710 one's falling in jupiter and one's falling on earth would you get would it 1934 00:36:12,710 --> 00:36:12,720 falling on earth would you get would it 1935 00:36:12,720 --> 00:36:14,790 falling on earth would you get would it have more energy is that the question 1936 00:36:14,790 --> 00:36:14,800 have more energy is that the question 1937 00:36:14,800 --> 00:36:16,870 have more energy is that the question we have more energy on jupiter because 1938 00:36:16,870 --> 00:36:16,880 we have more energy on jupiter because 1939 00:36:16,880 --> 00:36:18,790 we have more energy on jupiter because jupiter has a larger mass and therefore 1940 00:36:18,790 --> 00:36:18,800 jupiter has a larger mass and therefore 1941 00:36:18,800 --> 00:36:20,470 jupiter has a larger mass and therefore exactly 1942 00:36:20,470 --> 00:36:20,480 exactly 1943 00:36:20,480 --> 00:36:22,950 exactly uh jupiter is accelerating these objects 1944 00:36:22,950 --> 00:36:22,960 uh jupiter is accelerating these objects 1945 00:36:22,960 --> 00:36:24,470 uh jupiter is accelerating these objects as they come in 1946 00:36:24,470 --> 00:36:24,480 as they come in 1947 00:36:24,480 --> 00:36:26,870 as they come in and in fact the the velocity with which 1948 00:36:26,870 --> 00:36:26,880 and in fact the the velocity with which 1949 00:36:26,880 --> 00:36:28,390 and in fact the the velocity with which these fragments are hitting jupiter 1950 00:36:28,390 --> 00:36:28,400 these fragments are hitting jupiter 1951 00:36:28,400 --> 00:36:30,150 these fragments are hitting jupiter essentially is the escape velocity from 1952 00:36:30,150 --> 00:36:30,160 essentially is the escape velocity from 1953 00:36:30,160 --> 00:36:32,790 essentially is the escape velocity from jupiter's very and that's 60 kilometers 1954 00:36:32,790 --> 00:36:32,800 jupiter's very and that's 60 kilometers 1955 00:36:32,800 --> 00:36:33,910 jupiter's very and that's 60 kilometers per second 1956 00:36:33,910 --> 00:36:33,920 per second 1957 00:36:33,920 --> 00:36:36,310 per second whereas uh if you had an object that 1958 00:36:36,310 --> 00:36:36,320 whereas uh if you had an object that 1959 00:36:36,320 --> 00:36:38,230 whereas uh if you had an object that just fell in at the escape velocity on 1960 00:36:38,230 --> 00:36:38,240 just fell in at the escape velocity on 1961 00:36:38,240 --> 00:36:40,710 just fell in at the escape velocity on the earth that's only 11.2 kilometers 1962 00:36:40,710 --> 00:36:40,720 the earth that's only 11.2 kilometers 1963 00:36:40,720 --> 00:36:42,790 the earth that's only 11.2 kilometers per second and the energy's going is the 1964 00:36:42,790 --> 00:36:42,800 per second and the energy's going is the 1965 00:36:42,800 --> 00:36:45,109 per second and the energy's going is the square of the difference so it's it's a 1966 00:36:45,109 --> 00:36:45,119 square of the difference so it's it's a 1967 00:36:45,119 --> 00:36:46,950 square of the difference so it's it's a factor of five and a half or something 1968 00:36:46,950 --> 00:36:46,960 factor of five and a half or something 1969 00:36:46,960 --> 00:36:50,069 factor of five and a half or something like that square it so it's a factor of 1970 00:36:50,069 --> 00:36:50,079 like that square it so it's a factor of 1971 00:36:50,079 --> 00:36:52,069 like that square it so it's a factor of difference of 30 in the energy that you 1972 00:36:52,069 --> 00:36:52,079 difference of 30 in the energy that you 1973 00:36:52,079 --> 00:36:54,710 difference of 30 in the energy that you would get if so something just falls in 1974 00:36:54,710 --> 00:36:54,720 would get if so something just falls in 1975 00:36:54,720 --> 00:36:57,430 would get if so something just falls in at the escape velocity 1976 00:36:57,430 --> 00:36:57,440 at the escape velocity 1977 00:36:57,440 --> 00:37:00,069 at the escape velocity uh this is mark of houston chronicle i 1978 00:37:00,069 --> 00:37:00,079 uh this is mark of houston chronicle i 1979 00:37:00,079 --> 00:37:02,870 uh this is mark of houston chronicle i think i appreciate how optimally the 1980 00:37:02,870 --> 00:37:02,880 think i appreciate how optimally the 1981 00:37:02,880 --> 00:37:05,109 think i appreciate how optimally the planet was turned to get this picture 1982 00:37:05,109 --> 00:37:05,119 planet was turned to get this picture 1983 00:37:05,119 --> 00:37:06,870 planet was turned to get this picture but i'm just curious 1984 00:37:06,870 --> 00:37:06,880 but i'm just curious 1985 00:37:06,880 --> 00:37:09,829 but i'm just curious if this impact had had happened sooner 1986 00:37:09,829 --> 00:37:09,839 if this impact had had happened sooner 1987 00:37:09,839 --> 00:37:12,310 if this impact had had happened sooner would it have been on the far side and 1988 00:37:12,310 --> 00:37:12,320 would it have been on the far side and 1989 00:37:12,320 --> 00:37:13,910 would it have been on the far side and you would have missed it is there any 1990 00:37:13,910 --> 00:37:13,920 you would have missed it is there any 1991 00:37:13,920 --> 00:37:15,030 you would have missed it is there any kind of a 1992 00:37:15,030 --> 00:37:15,040 kind of a 1993 00:37:15,040 --> 00:37:17,510 kind of a a timing you can give us as to how how 1994 00:37:17,510 --> 00:37:17,520 a timing you can give us as to how how 1995 00:37:17,520 --> 00:37:20,870 a timing you can give us as to how how lucky you were to capture this thing 1996 00:37:20,870 --> 00:37:20,880 lucky you were to capture this thing 1997 00:37:20,880 --> 00:37:22,870 lucky you were to capture this thing well there the impacts are always 1998 00:37:22,870 --> 00:37:22,880 well there the impacts are always 1999 00:37:22,880 --> 00:37:25,670 well there the impacts are always occurring on the far side timing is 2000 00:37:25,670 --> 00:37:25,680 occurring on the far side timing is 2001 00:37:25,680 --> 00:37:27,829 occurring on the far side timing is irrelevant because they're coming in on 2002 00:37:27,829 --> 00:37:27,839 irrelevant because they're coming in on 2003 00:37:27,839 --> 00:37:29,910 irrelevant because they're coming in on a line that always is the same 2004 00:37:29,910 --> 00:37:29,920 a line that always is the same 2005 00:37:29,920 --> 00:37:33,109 a line that always is the same orientation relative for us and jupiter 2006 00:37:33,109 --> 00:37:33,119 orientation relative for us and jupiter 2007 00:37:33,119 --> 00:37:33,829 orientation relative for us and jupiter so 2008 00:37:33,829 --> 00:37:33,839 so 2009 00:37:33,839 --> 00:37:35,510 so it wouldn't matter if it came in earlier 2010 00:37:35,510 --> 00:37:35,520 it wouldn't matter if it came in earlier 2011 00:37:35,520 --> 00:37:38,630 it wouldn't matter if it came in earlier late we would never be able to see it 2012 00:37:38,630 --> 00:37:38,640 late we would never be able to see it 2013 00:37:38,640 --> 00:37:41,109 late we would never be able to see it in terms of the timing of the imaging 2014 00:37:41,109 --> 00:37:41,119 in terms of the timing of the imaging 2015 00:37:41,119 --> 00:37:42,630 in terms of the timing of the imaging that we took 2016 00:37:42,630 --> 00:37:42,640 that we took 2017 00:37:42,640 --> 00:37:46,150 that we took that for for our program was really 2018 00:37:46,150 --> 00:37:46,160 that for for our program was really 2019 00:37:46,160 --> 00:37:48,870 that for for our program was really limited by the rotation of the hubble 2020 00:37:48,870 --> 00:37:48,880 limited by the rotation of the hubble 2021 00:37:48,880 --> 00:37:51,270 limited by the rotation of the hubble the um the hubble space telescopes orbit 2022 00:37:51,270 --> 00:37:51,280 the um the hubble space telescopes orbit 2023 00:37:51,280 --> 00:37:53,910 the um the hubble space telescopes orbit around the earth it orbits every 96 2024 00:37:53,910 --> 00:37:53,920 around the earth it orbits every 96 2025 00:37:53,920 --> 00:37:56,069 around the earth it orbits every 96 minutes and obviously we can only look 2026 00:37:56,069 --> 00:37:56,079 minutes and obviously we can only look 2027 00:37:56,079 --> 00:37:58,069 minutes and obviously we can only look at it at jupiter when the space 2028 00:37:58,069 --> 00:37:58,079 at it at jupiter when the space 2029 00:37:58,079 --> 00:38:00,150 at it at jupiter when the space telescope is on the side of the earth 2030 00:38:00,150 --> 00:38:00,160 telescope is on the side of the earth 2031 00:38:00,160 --> 00:38:02,310 telescope is on the side of the earth that jupiter is visible you can't look 2032 00:38:02,310 --> 00:38:02,320 that jupiter is visible you can't look 2033 00:38:02,320 --> 00:38:04,710 that jupiter is visible you can't look through the earth so 2034 00:38:04,710 --> 00:38:04,720 through the earth so 2035 00:38:04,720 --> 00:38:07,270 through the earth so in some sense we have been extremely 2036 00:38:07,270 --> 00:38:07,280 in some sense we have been extremely 2037 00:38:07,280 --> 00:38:09,910 in some sense we have been extremely lucky to have captured three of these 2038 00:38:09,910 --> 00:38:09,920 lucky to have captured three of these 2039 00:38:09,920 --> 00:38:12,150 lucky to have captured three of these impact events in the middle of one of 2040 00:38:12,150 --> 00:38:12,160 impact events in the middle of one of 2041 00:38:12,160 --> 00:38:14,950 impact events in the middle of one of the hubble's visibility windows 2042 00:38:14,950 --> 00:38:14,960 the hubble's visibility windows 2043 00:38:14,960 --> 00:38:18,550 the hubble's visibility windows and it's almost by definition if if that 2044 00:38:18,550 --> 00:38:18,560 and it's almost by definition if if that 2045 00:38:18,560 --> 00:38:20,790 and it's almost by definition if if that impact plume is visible 2046 00:38:20,790 --> 00:38:20,800 impact plume is visible 2047 00:38:20,800 --> 00:38:23,670 impact plume is visible then one and a half hours later we'll be 2048 00:38:23,670 --> 00:38:23,680 then one and a half hours later we'll be 2049 00:38:23,680 --> 00:38:26,230 then one and a half hours later we'll be able to take a picture of the site on 2050 00:38:26,230 --> 00:38:26,240 able to take a picture of the site on 2051 00:38:26,240 --> 00:38:27,829 able to take a picture of the site on just on the disk of the planet because 2052 00:38:27,829 --> 00:38:27,839 just on the disk of the planet because 2053 00:38:27,839 --> 00:38:30,470 just on the disk of the planet because that's how fast jupiter rotates 2054 00:38:30,470 --> 00:38:30,480 that's how fast jupiter rotates 2055 00:38:30,480 --> 00:38:31,349 that's how fast jupiter rotates so 2056 00:38:31,349 --> 00:38:31,359 so 2057 00:38:31,359 --> 00:38:33,990 so we were fortunate to have the hubble in 2058 00:38:33,990 --> 00:38:34,000 we were fortunate to have the hubble in 2059 00:38:34,000 --> 00:38:35,589 we were fortunate to have the hubble in the right place at the right time to be 2060 00:38:35,589 --> 00:38:35,599 the right place at the right time to be 2061 00:38:35,599 --> 00:38:37,589 the right place at the right time to be able to capture this one we couldn't 2062 00:38:37,589 --> 00:38:37,599 able to capture this one we couldn't 2063 00:38:37,599 --> 00:38:38,950 able to capture this one we couldn't have done anything if the hubble had 2064 00:38:38,950 --> 00:38:38,960 have done anything if the hubble had 2065 00:38:38,960 --> 00:38:40,870 have done anything if the hubble had been on the other side of the earth 2066 00:38:40,870 --> 00:38:40,880 been on the other side of the earth 2067 00:38:40,880 --> 00:38:42,470 been on the other side of the earth i think part of the answer the question 2068 00:38:42,470 --> 00:38:42,480 i think part of the answer the question 2069 00:38:42,480 --> 00:38:45,270 i think part of the answer the question heidi is that we already had very good 2070 00:38:45,270 --> 00:38:45,280 heidi is that we already had very good 2071 00:38:45,280 --> 00:38:46,790 heidi is that we already had very good predictions 2072 00:38:46,790 --> 00:38:46,800 predictions 2073 00:38:46,800 --> 00:38:48,550 predictions of the impact times they were they were 2074 00:38:48,550 --> 00:38:48,560 of the impact times they were they were 2075 00:38:48,560 --> 00:38:51,670 of the impact times they were they were certainly good to within 15 minutes 2076 00:38:51,670 --> 00:38:51,680 certainly good to within 15 minutes 2077 00:38:51,680 --> 00:38:53,990 certainly good to within 15 minutes and so that that was extraordinarily 2078 00:38:53,990 --> 00:38:54,000 and so that that was extraordinarily 2079 00:38:54,000 --> 00:38:57,349 and so that that was extraordinarily important in the timing and the planning 2080 00:38:57,349 --> 00:38:57,359 important in the timing and the planning 2081 00:38:57,359 --> 00:38:59,910 important in the timing and the planning for uh for these images that was a very 2082 00:38:59,910 --> 00:38:59,920 for uh for these images that was a very 2083 00:38:59,920 --> 00:39:01,190 for uh for these images that was a very essential part 2084 00:39:01,190 --> 00:39:01,200 essential part 2085 00:39:01,200 --> 00:39:02,950 essential part not really gene 2086 00:39:02,950 --> 00:39:02,960 not really gene 2087 00:39:02,960 --> 00:39:04,950 not really gene because we we had to do the planning in 2088 00:39:04,950 --> 00:39:04,960 because we we had to do the planning in 2089 00:39:04,960 --> 00:39:08,069 because we we had to do the planning in the sequences many weeks ago months ago 2090 00:39:08,069 --> 00:39:08,079 the sequences many weeks ago months ago 2091 00:39:08,079 --> 00:39:10,630 the sequences many weeks ago months ago and the impact times were not well known 2092 00:39:10,630 --> 00:39:10,640 and the impact times were not well known 2093 00:39:10,640 --> 00:39:11,910 and the impact times were not well known and the hubble's orbit was not 2094 00:39:11,910 --> 00:39:11,920 and the hubble's orbit was not 2095 00:39:11,920 --> 00:39:13,510 and the hubble's orbit was not particularly well known either because 2096 00:39:13,510 --> 00:39:13,520 particularly well known either because 2097 00:39:13,520 --> 00:39:15,510 particularly well known either because that has to be adjusted fairly 2098 00:39:15,510 --> 00:39:15,520 that has to be adjusted fairly 2099 00:39:15,520 --> 00:39:18,550 that has to be adjusted fairly frequently and so at in some sense it 2100 00:39:18,550 --> 00:39:18,560 frequently and so at in some sense it 2101 00:39:18,560 --> 00:39:21,750 frequently and so at in some sense it was potluck and and as as the predicts 2102 00:39:21,750 --> 00:39:21,760 was potluck and and as as the predicts 2103 00:39:21,760 --> 00:39:24,710 was potluck and and as as the predicts were coming in and changing forward 2104 00:39:24,710 --> 00:39:24,720 were coming in and changing forward 2105 00:39:24,720 --> 00:39:26,950 were coming in and changing forward backwards for they would be hopping in 2106 00:39:26,950 --> 00:39:26,960 backwards for they would be hopping in 2107 00:39:26,960 --> 00:39:28,870 backwards for they would be hopping in and out of orbits and i'd be getting 2108 00:39:28,870 --> 00:39:28,880 and out of orbits and i'd be getting 2109 00:39:28,880 --> 00:39:30,950 and out of orbits and i'd be getting very nervous and then i'd be very happy 2110 00:39:30,950 --> 00:39:30,960 very nervous and then i'd be very happy 2111 00:39:30,960 --> 00:39:33,670 very nervous and then i'd be very happy and i'd be nervous again and and so i 2112 00:39:33,670 --> 00:39:33,680 and i'd be nervous again and and so i 2113 00:39:33,680 --> 00:39:35,750 and i'd be nervous again and and so i ended up being very happy but but you 2114 00:39:35,750 --> 00:39:35,760 ended up being very happy but but you 2115 00:39:35,760 --> 00:39:36,950 ended up being very happy but but you certainly were doing your initial 2116 00:39:36,950 --> 00:39:36,960 certainly were doing your initial 2117 00:39:36,960 --> 00:39:39,030 certainly were doing your initial planning based based on that of course 2118 00:39:39,030 --> 00:39:39,040 planning based based on that of course 2119 00:39:39,040 --> 00:39:40,870 planning based based on that of course from the chodest and yeoman's pre-that's 2120 00:39:40,870 --> 00:39:40,880 from the chodest and yeoman's pre-that's 2121 00:39:40,880 --> 00:39:42,710 from the chodest and yeoman's pre-that's right but there were victims but it was 2122 00:39:42,710 --> 00:39:42,720 right but there were victims but it was 2123 00:39:42,720 --> 00:39:44,230 right but there were victims but it was but there was a lot of luck that it came 2124 00:39:44,230 --> 00:39:44,240 but there was a lot of luck that it came 2125 00:39:44,240 --> 00:39:45,910 but there was a lot of luck that it came out a lot of luck we've been very 2126 00:39:45,910 --> 00:39:45,920 out a lot of luck we've been very 2127 00:39:45,920 --> 00:39:47,670 out a lot of luck we've been very fortunate 2128 00:39:47,670 --> 00:39:47,680 fortunate 2129 00:39:47,680 --> 00:39:54,829 fortunate got a question in the middle right over 2130 00:39:54,829 --> 00:39:54,839 2131 00:39:54,839 --> 00:39:57,510 here tracy watson u.s news and world 2132 00:39:57,510 --> 00:39:57,520 here tracy watson u.s news and world 2133 00:39:57,520 --> 00:39:59,829 here tracy watson u.s news and world report first of all um i'd heard that 2134 00:39:59,829 --> 00:39:59,839 report first of all um i'd heard that 2135 00:39:59,839 --> 00:40:01,510 report first of all um i'd heard that looking at the plume may indicate 2136 00:40:01,510 --> 00:40:01,520 looking at the plume may indicate 2137 00:40:01,520 --> 00:40:04,710 looking at the plume may indicate sometime what the composition of the 2138 00:40:04,710 --> 00:40:04,720 sometime what the composition of the 2139 00:40:04,720 --> 00:40:07,190 sometime what the composition of the impactors was and will eventually tell 2140 00:40:07,190 --> 00:40:07,200 impactors was and will eventually tell 2141 00:40:07,200 --> 00:40:08,470 impactors was and will eventually tell us whether it really was a comet or 2142 00:40:08,470 --> 00:40:08,480 us whether it really was a comet or 2143 00:40:08,480 --> 00:40:10,230 us whether it really was a comet or whether it was an asteroid how long do 2144 00:40:10,230 --> 00:40:10,240 whether it was an asteroid how long do 2145 00:40:10,240 --> 00:40:11,270 whether it was an asteroid how long do you think it'll take you to come out 2146 00:40:11,270 --> 00:40:11,280 you think it'll take you to come out 2147 00:40:11,280 --> 00:40:13,430 you think it'll take you to come out with that kind of information 2148 00:40:13,430 --> 00:40:13,440 with that kind of information 2149 00:40:13,440 --> 00:40:15,510 with that kind of information i'm not sure we'll get that information 2150 00:40:15,510 --> 00:40:15,520 i'm not sure we'll get that information 2151 00:40:15,520 --> 00:40:17,990 i'm not sure we'll get that information from the plume itself although we'll 2152 00:40:17,990 --> 00:40:18,000 from the plume itself although we'll 2153 00:40:18,000 --> 00:40:19,990 from the plume itself although we'll have to think about that for a while i 2154 00:40:19,990 --> 00:40:20,000 have to think about that for a while i 2155 00:40:20,000 --> 00:40:21,910 have to think about that for a while i think it's more likely that kind of 2156 00:40:21,910 --> 00:40:21,920 think it's more likely that kind of 2157 00:40:21,920 --> 00:40:23,430 think it's more likely that kind of information is going to come from 2158 00:40:23,430 --> 00:40:23,440 information is going to come from 2159 00:40:23,440 --> 00:40:25,349 information is going to come from spectroscopy 2160 00:40:25,349 --> 00:40:25,359 spectroscopy 2161 00:40:25,359 --> 00:40:28,150 spectroscopy of the impact sites the fresh impact 2162 00:40:28,150 --> 00:40:28,160 of the impact sites the fresh impact 2163 00:40:28,160 --> 00:40:30,470 of the impact sites the fresh impact sites and that work will be done with a 2164 00:40:30,470 --> 00:40:30,480 sites and that work will be done with a 2165 00:40:30,480 --> 00:40:33,030 sites and that work will be done with a variety of instruments hubble is one of 2166 00:40:33,030 --> 00:40:33,040 variety of instruments hubble is one of 2167 00:40:33,040 --> 00:40:35,030 variety of instruments hubble is one of them in fact we had a very exciting 2168 00:40:35,030 --> 00:40:35,040 them in fact we had a very exciting 2169 00:40:35,040 --> 00:40:37,510 them in fact we had a very exciting exercise this morning where we got that 2170 00:40:37,510 --> 00:40:37,520 exercise this morning where we got that 2171 00:40:37,520 --> 00:40:39,430 exercise this morning where we got that first image that i showed you of the 2172 00:40:39,430 --> 00:40:39,440 first image that i showed you of the 2173 00:40:39,440 --> 00:40:40,710 first image that i showed you of the impact site 2174 00:40:40,710 --> 00:40:40,720 impact site 2175 00:40:40,720 --> 00:40:44,630 impact site on the limb and in real time we measured 2176 00:40:44,630 --> 00:40:44,640 on the limb and in real time we measured 2177 00:40:44,640 --> 00:40:46,950 on the limb and in real time we measured exactly where the space tells telescope 2178 00:40:46,950 --> 00:40:46,960 exactly where the space tells telescope 2179 00:40:46,960 --> 00:40:48,310 exactly where the space tells telescope was pointing 2180 00:40:48,310 --> 00:40:48,320 was pointing 2181 00:40:48,320 --> 00:40:50,310 was pointing and then offset the telescope to be 2182 00:40:50,310 --> 00:40:50,320 and then offset the telescope to be 2183 00:40:50,320 --> 00:40:54,069 and then offset the telescope to be pointing exactly at the impact site and 2184 00:40:54,069 --> 00:40:54,079 pointing exactly at the impact site and 2185 00:40:54,079 --> 00:40:55,670 pointing exactly at the impact site and sent the instructions up to the 2186 00:40:55,670 --> 00:40:55,680 sent the instructions up to the 2187 00:40:55,680 --> 00:40:57,510 sent the instructions up to the spacecraft normally we don't do that we 2188 00:40:57,510 --> 00:40:57,520 spacecraft normally we don't do that we 2189 00:40:57,520 --> 00:40:59,589 spacecraft normally we don't do that we plan weeks and months in advance and 2190 00:40:59,589 --> 00:40:59,599 plan weeks and months in advance and 2191 00:40:59,599 --> 00:41:01,270 plan weeks and months in advance and keith knoll is the principal 2192 00:41:01,270 --> 00:41:01,280 keith knoll is the principal 2193 00:41:01,280 --> 00:41:03,910 keith knoll is the principal investigator of that experiment and at 2194

that he has some good results to 2199 00:41:08,960 --> 00:41:10,390 that he has some good results to to share with you 2200 00:41:10,390 --> 00:41:10,400 to share with you 2201 00:41:10,400 --> 00:41:12,630 to share with you other telescopes like the irtf and 2202 00:41:12,630 --> 00:41:12,640 other telescopes like the irtf and 2203 00:41:12,640 --> 00:41:14,630 other telescopes like the irtf and nasa's kuiper airborne observatory will 2204 00:41:14,630 --> 00:41:14,640 nasa's kuiper airborne observatory will 2205 00:41:14,640 --> 00:41:16,710 nasa's kuiper airborne observatory will be instrumental in doing the kind of 2206 00:41:16,710 --> 00:41:16,720 be instrumental in doing the kind of 2207 00:41:16,720 --> 00:41:19,750 be instrumental in doing the kind of spectroscopy to probe the chemistry of 2208 00:41:19,750 --> 00:41:19,760 spectroscopy to probe the chemistry of 2209 00:41:19,760 --> 00:41:22,790 spectroscopy to probe the chemistry of the atmosphere and of you know any 2210 00:41:22,790 --> 00:41:22,800 the atmosphere and of you know any 2211 00:41:22,800 --> 00:41:24,470 the atmosphere and of you know any mushed up comet that happened to be 2212 00:41:24,470 --> 00:41:24,480 mushed up comet that happened to be 2213 00:41:24,480 --> 00:41:27,430 mushed up comet that happened to be there 2214 00:41:27,430 --> 00:41:27,440 2215 00:41:27,440 --> 00:41:29,910 bill harwood cb cbs again 2216 00:41:29,910 --> 00:41:29,920 bill harwood cb cbs again 2217 00:41:29,920 --> 00:41:31,589 bill harwood cb cbs again i think i know the answer but this this 2218 00:41:31,589 --> 00:41:31,599 i think i know the answer but this this 2219 00:41:31,599 --> 00:41:32,710 i think i know the answer but this this is something that should be clearly 2220 00:41:32,710 --> 00:41:32,720 is something that should be clearly 2221 00:41:32,720 --> 00:41:34,390 is something that should be clearly visible to amateurs is it not i mean 2222 00:41:34,390 --> 00:41:34,400 visible to amateurs is it not i mean 2223 00:41:34,400 --> 00:41:36,710 visible to amateurs is it not i mean given its size or is the wavelength such 2224 00:41:36,710 --> 00:41:36,720 given its size or is the wavelength such 2225 00:41:36,720 --> 00:41:38,069 given its size or is the wavelength such that it's not going to be visible like 2226 00:41:38,069 --> 00:41:38,079 that it's not going to be visible like 2227 00:41:38,079 --> 00:41:39,109 that it's not going to be visible like which 2228 00:41:39,109 --> 00:41:39,119 which 2229 00:41:39,119 --> 00:41:40,950 which well these black spots are starting to 2230 00:41:40,950 --> 00:41:40,960 well these black spots are starting to 2231 00:41:40,960 --> 00:41:43,349 well these black spots are starting to get pretty darn big and 2232 00:41:43,349 --> 00:41:43,359 get pretty darn big and 2233 00:41:43,359 --> 00:41:45,030 get pretty darn big and you know close to the size of the great 2234 00:41:45,030 --> 00:41:45,040 you know close to the size of the great 2235 00:41:45,040 --> 00:41:46,550 you know close to the size of the great red spot 2236 00:41:46,550 --> 00:41:46,560 red spot 2237 00:41:46,560 --> 00:41:48,150 red spot and i believe there have been some 2238 00:41:48,150 --> 00:41:48,160 and i believe there have been some 2239 00:41:48,160 --> 00:41:50,230 and i believe there have been some reports from visual observers who are 2240 00:41:50,230 --> 00:41:50,240 reports from visual observers who are 2241 00:41:50,240 --> 00:41:52,470 reports from visual observers who are starting to see them now remember 2242 00:41:52,470 --> 00:41:52,480 starting to see them now remember 2243 00:41:52,480 --> 00:41:54,790 starting to see them now remember you have a very high resolution image in 2244 00:41:54,790 --> 00:41:54,800 you have a very high resolution image in 2245 00:41:54,800 --> 00:41:56,150 you have a very high resolution image in front of you with the hubble space 2246 00:41:56,150 --> 00:41:56,160 front of you with the hubble space 2247 00:41:56,160 --> 00:41:58,150 front of you with the hubble space telescope and with the ground-based 2248 00:41:58,150 --> 00:41:58,160 telescope and with the ground-based 2249 00:41:58,160 --> 00:42:01,190 telescope and with the ground-based telescope much of this is smeared out 2250 00:42:01,190 --> 00:42:01,200 telescope much of this is smeared out 2251 00:42:01,200 --> 00:42:03,750 telescope much of this is smeared out so it isn't anything like you're seeing 2252 00:42:03,750 --> 00:42:03,760 so it isn't anything like you're seeing 2253 00:42:03,760 --> 00:42:05,670 so it isn't anything like you're seeing here through a ground-based telescope 2254 00:42:05,670 --> 00:42:05,680 here through a ground-based telescope 2255 00:42:05,680 --> 00:42:08,470 here through a ground-based telescope but the short answer is that yes it 2256 00:42:08,470 --> 00:42:08,480 but the short answer is that yes it 2257 00:42:08,480 --> 00:42:10,390 but the short answer is that yes it these are this is starting to get large 2258 00:42:10,390 --> 00:42:10,400 these are this is starting to get large 2259 00:42:10,400 --> 00:42:12,950 these are this is starting to get large enough that that amateurs may be able to 2260 00:42:12,950 --> 00:42:12,960 enough that that amateurs may be able to 2261 00:42:12,960 --> 00:42:14,950 enough that that amateurs may be able to spot these if they're very careful 2262 00:42:14,950 --> 00:42:14,960 spot these if they're very careful 2263 00:42:14,960 --> 00:42:17,190 spot these if they're very careful observers and know what to look for and 2264 00:42:17,190 --> 00:42:17,200 observers and know what to look for and 2265 00:42:17,200 --> 00:42:20,550 observers and know what to look for and that three three impact sequence 2266 00:42:20,550 --> 00:42:20,560 that three three impact sequence 2267 00:42:20,560 --> 00:42:22,470 that three three impact sequence may stir up a real big portion of 2268 00:42:22,470 --> 00:42:22,480 may stir up a real big portion of 2269 00:42:22,480 --> 00:42:25,109 may stir up a real big portion of atmosphere may get very dark it's also 2270 00:42:25,109 --> 00:42:25,119 atmosphere may get very dark it's also 2271 00:42:25,119 --> 00:42:28,390 atmosphere may get very dark it's also possible that with time as the winds on 2272 00:42:28,390 --> 00:42:28,400 possible that with time as the winds on 2273 00:42:28,400 --> 00:42:30,069 possible that with time as the winds on jupiter start to distribute this 2274 00:42:30,069 --> 00:42:30,079 jupiter start to distribute this 2275 00:42:30,079 --> 00:42:31,430 jupiter start to distribute this material 2276 00:42:31,430 --> 00:42:31,440 material 2277 00:42:31,440 --> 00:42:33,670 material it's possible that a slightly darker 2278 00:42:33,670 --> 00:42:33,680 it's possible that a slightly darker 2279 00:42:33,680 --> 00:42:36,390 it's possible that a slightly darker band will will develop in this in this 2280 00:42:36,390 --> 00:42:36,400 band will will develop in this in this 2281 00:42:36,400 --> 00:42:38,150 band will will develop in this in this latitudinal region 2282 00:42:38,150 --> 00:42:38,160 latitudinal region 2283 00:42:38,160 --> 00:42:40,150 latitudinal region we say it's possible because as i 2284 00:42:40,150 --> 00:42:40,160 we say it's possible because as i 2285 00:42:40,160 --> 00:42:42,870 we say it's possible because as i mentioned this material appears to be 2286 00:42:42,870 --> 00:42:42,880 mentioned this material appears to be 2287 00:42:42,880 --> 00:42:46,309 mentioned this material appears to be very thinly deposited over that region 2288 00:42:46,309 --> 00:42:46,319 very thinly deposited over that region 2289 00:42:46,319 --> 00:42:48,390 very thinly deposited over that region and so it's not clear if you start 2290 00:42:48,390 --> 00:42:48,400 and so it's not clear if you start 2291 00:42:48,400 --> 00:42:50,630 and so it's not clear if you start spreading out that thin layer whether or 2292 00:42:50,630 --> 00:42:50,640 spreading out that thin layer whether or 2293 00:42:50,640 --> 00:42:51,990 spreading out that thin layer whether or not there's enough there to make the 2294 00:42:51,990 --> 00:42:52,000 not there's enough there to make the 2295 00:42:52,000 --> 00:42:54,710 not there's enough there to make the band dark we'll see that as it develops 2296 00:42:54,710 --> 00:42:54,720 band dark we'll see that as it develops 2297 00:42:54,720 --> 00:42:56,630 band dark we'll see that as it develops over the next week or two 2298 00:42:56,630 --> 00:42:56,640 over the next week or two 2299 00:42:56,640 --> 00:42:58,950 over the next week or two i think there's a good chance that that 2300 00:42:58,950 --> 00:42:58,960 i think there's a good chance that that 2301 00:42:58,960 --> 00:43:01,270 i think there's a good chance that that amateurs with eight inch diameter 2302 00:43:01,270 --> 00:43:01,280 amateurs with eight inch diameter 2303 00:43:01,280 --> 00:43:03,670 amateurs with eight inch diameter telescopes or bigger 2304 00:43:03,670 --> 00:43:03,680 telescopes or bigger 2305 00:43:03,680 --> 00:43:06,150 telescopes or bigger in good sites where they have very good 2306 00:43:06,150 --> 00:43:06,160 in good sites where they have very good 2307 00:43:06,160 --> 00:43:07,670 in good sites where they have very good seeing 2308 00:43:07,670 --> 00:43:07,680 seeing 2309 00:43:07,680 --> 00:43:10,230 seeing will be able to see these i think and 2310 00:43:10,230 --> 00:43:10,240 will be able to see these i think and 2311 00:43:10,240 --> 00:43:11,990 will be able to see these i think and already there are reports from from 2312 00:43:11,990 --> 00:43:12,000 already there are reports from from 2313 00:43:12,000 --> 00:43:14,630 already there are reports from from quite reliable observers there's a 2314 00:43:14,630 --> 00:43:14,640 quite reliable observers there's a 2315 00:43:14,640 --> 00:43:16,309 quite reliable observers there's a graphic we can show you that was shown 2316 00:43:16,309 --> 00:43:16,319 graphic we can show you that was shown 2317 00:43:16,319 --> 00:43:18,390 graphic we can show you that was shown this morning which is the full disk of 2318 00:43:18,390 --> 00:43:18,400 this morning which is the full disk of 2319 00:43:18,400 --> 00:43:20,550 this morning which is the full disk of jupiter and the three impact sites on 2320 00:43:20,550 --> 00:43:20,560 jupiter and the three impact sites on 2321 00:43:20,560 --> 00:43:22,550 jupiter and the three impact sites on the bottom and i believe they have that 2322 00:43:22,550 --> 00:43:22,560 the bottom and i believe they have that 2323 00:43:22,560 --> 00:43:25,270 the bottom and i believe they have that they can put on there it is you can see 2324 00:43:25,270 --> 00:43:25,280 they can put on there it is you can see 2325 00:43:25,280 --> 00:43:27,190 they can put on there it is you can see the bands on jupiter this is roughly a 2326 00:43:27,190 --> 00:43:27,200 the bands on jupiter this is roughly a 2327 00:43:27,200 --> 00:43:29,349 the bands on jupiter this is roughly a visual image this is a green wavelength 2328 00:43:29,349 --> 00:43:29,359 visual image this is a green wavelength 2329 00:43:29,359 --> 00:43:31,190 visual image this is a green wavelength and that's more or less you know what 2330 00:43:31,190 --> 00:43:31,200 and that's more or less you know what 2331 00:43:31,200 --> 00:43:33,109 and that's more or less you know what you would see with your eye and you can 2332 00:43:33,109 --> 00:43:33,119 you would see with your eye and you can 2333 00:43:33,119 --> 00:43:34,790 you would see with your eye and you can see the bands and you can see the great 2334 00:43:34,790 --> 00:43:34,800 see the bands and you can see the great 2335 00:43:34,800 --> 00:43:36,870 see the bands and you can see the great red spot and you can see the little dark 2336 00:43:36,870 --> 00:43:36,880 red spot and you can see the little dark 2337 00:43:36,880 --> 00:43:39,589 red spot and you can see the little dark splotches following after the great red 2338 00:43:39,589 --> 00:43:39,599 splotches following after the great red 2339 00:43:39,599 --> 00:43:40,390 splotches following after the great red spot 2340 00:43:40,390 --> 00:43:40,400 spot 2341 00:43:40,400 --> 00:43:41,829 spot all right so if you can see the great 2342 00:43:41,829 --> 00:43:41,839 all right so if you can see the great 2343 00:43:41,839 --> 00:43:45,030 all right so if you can see the great red spot moving it would start on on the 2344 00:43:45,030 --> 00:43:45,040 red spot moving it would start on on the 2345 00:43:45,040 --> 00:43:46,950 red spot moving it would start on on the left of this image and move to the right 2346 00:43:46,950 --> 00:43:46,960 left of this image and move to the right 2347 00:43:46,960 --> 00:43:48,710 left of this image and move to the right then look further south for that little 2348 00:43:48,710 --> 00:43:48,720 then look further south for that little 2349 00:43:48,720 --> 00:43:50,790 then look further south for that little train of dark features and 2350 00:43:50,790 --> 00:43:50,800 train of dark features and 2351 00:43:50,800 --> 00:43:54,309 train of dark features and you may see it 2352 00:43:54,309 --> 00:43:54,319 you may see it 2353 00:43:54,319 --> 00:43:56,069 you may see it all right if there are no more questions 2354 00:43:56,069 --> 00:43:56,079 all right if there are no more questions 2355 00:43:56,079 --> 00:43:57,670 all right if there are no more questions we'll wrap it up here we want to thank 2356 00:43:57,670 --> 00:43:57,680 we'll wrap it up here we want to thank 2357 00:43:57,680 --> 00:43:59,510 we'll wrap it up here we want to thank everybody for their interest and we'll 2358 00:43:59,510 --> 00:43:59,520 everybody for their interest and we'll 2359 00:43:59,520 --> 00:44:04,230 everybody for their interest and we'll see you 2360 00:44:04,230 --> 00:44:04,240 2361 00:44:04,240 --> 00:44:06,470 okay if any if people want to stay we're 2362 00:44:06,470 --> 00:44:06,480 okay if any if people want to stay we're 2363 00:44:06,480 --> 00:44:08,710 okay if any if people want to stay we're going to roll some uh some visuals uh up 2364 00:44:08,710 --> 00:44:08,720 going to roll some uh some visuals uh up 2365 00:44:08,720 --> 00:44:12,950 going to roll some uh some visuals uh up on the screen 2366
