1 00:03:15,870 --> 00:03:14,100 good evening welcome to the second of 2 00:03:17,730 --> 00:03:15,880 our briefings tonight at the Space 3 00:03:20,790 --> 00:03:17,740 Telescope Science Institute in Baltimore 4 00:03:23,580 --> 00:03:20,800 we have tonight with this dr. Heidi 5 00:03:25,020 --> 00:03:23,590 Hammel who will be discussing in just a 6 00:03:27,090 --> 00:03:25,030 moment the first image from the Hubble 7 00:03:37,920 --> 00:03:27,100 Space Telescope that we receive just a 8 00:03:42,190 --> 00:03:40,330 what you're seeing is a full disc of 9 00:03:45,039 --> 00:03:42,200 Jupiter taken with the with the wide 10 00:03:49,300 --> 00:03:45,049 field camera in a blue filter the 11 00:03:53,039 --> 00:03:49,310 wavelength is 410 nanometers and you see 12 00:03:55,990 --> 00:03:53,049 on the left a blow-up of the impact site 13 00:04:00,759 --> 00:03:56,000 it's expanded and enhanced so you can 14 00:04:05,860 --> 00:04:00,769 see it it's very dark we have 15 00:04:11,440 --> 00:04:05,870 wavelengths ranging from 3036 nanometers 16 00:04:13,000 --> 00:04:11,450 out to 9000 5956 nanometers we don't 17 00:04:14,470 --> 00:04:13,010 have those already to show you now 18 00:04:16,990 --> 00:04:14,480 because we obviously haven't had enough 19 00:04:20,199 --> 00:04:17,000 time to do that but I'd like to describe 20 00:04:23,710 --> 00:04:20,209 for you what it looks like at all 21 00:04:26,620 --> 00:04:23,720 wavelengths except a methane band it 22 00:04:30,279 --> 00:04:26,630 looks like this it's dark and it has 23 00:04:33,580 --> 00:04:30,289 this dark material to the south in the 24 00:04:36,129 --> 00:04:33,590 methane band image the wavelength is 889 25 00:04:39,850 --> 00:04:36,139 nanometers everything that you see is 26 00:04:44,620 --> 00:04:39,860 dark there is bright it's completely 27 00:04:46,270 --> 00:04:44,630 inverted looks like a negative image we 28 00:04:50,100 --> 00:04:46,280 don't fully understand what we're seeing 29 00:04:52,300 --> 00:04:50,110 here yet we don't have ready for you yet 30 00:04:56,409 --> 00:04:52,310 images that were taken in the previous 31 00:05:00,129 --> 00:04:56,419 orbit in that orbit what we could see at 32 00:05:03,339 --> 00:05:00,139 all wavelengths was what looked like a 33 00:05:06,399 --> 00:05:03,349 plume on the limb of the planet and then 34 00:05:10,839 --> 00:05:06,409 we saw the plume flatten as if it was 35 00:05:12,460 --> 00:05:10,849 spreading out and that was always saw we 36 00:05:15,939 --> 00:05:12,470 detected it at all those wavelengths 37 00:05:18,129 --> 00:05:15,949 though and so will be working throughout 38 00:05:22,810 --> 00:05:18,139 the night to get these data ready to 39 00:05:24,640 --> 00:05:22,820 show to you tomorrow morning I would now 40 00:05:26,469 --> 00:05:24,650 like to show you a video if any of you 41 00:05:29,140 --> 00:05:26,479 are not convinced that this is from this 42 00:05:30,460 --> 00:05:29,150 comment I i would like to show you a 43 00:05:32,980 --> 00:05:30,470 video of what jupiter looked like 44 00:05:35,800 --> 00:05:32,990 yesterday and this is brand-new 45 00:05:38,890 --> 00:05:35,810 preliminary data and it's a fairly RAW 46 00:05:42,040 --> 00:05:38,900 format so you'll see seams and colors 47 00:05:43,750 --> 00:05:42,050 that if we had had more than 18 hours we 48 00:05:46,480 --> 00:05:43,760 would have done a prettier job but I 49 00:05:47,709 --> 00:05:46,490 wanted you to see the quality of imaging 50 00:05:49,090 --> 00:05:47,719 that we're getting from the Hubble Space 51 00:05:52,030 --> 00:05:49,100 Telescope so 52 00:05:54,190 --> 00:05:52,040 we could run that video please it was 53 00:05:58,390 --> 00:05:54,200 created by Eric to young based on six 54 00:06:02,110 --> 00:05:58,400 orbits of data yesterday afternoon and I 55 00:06:07,630 --> 00:06:02,120 hope we have the video can you roll the 56 00:06:13,290 --> 00:06:07,640 video please okay it it's going out on 57 00:06:20,710 --> 00:06:16,600 this will basically take five different 58 00:06:22,720 --> 00:06:20,720 images of Hubble and what we have done 59 00:06:26,230 --> 00:06:22,730 is Matt project them and then recombine 60 00:06:31,930 --> 00:06:26,240 them to make basically a sphere I hope 61 00:06:34,240 --> 00:06:31,940 we do get to see it well while they're 62 00:06:36,100 --> 00:06:34,250 working on that let me just show you the 63 00:06:37,540 --> 00:06:36,110 geometry of this impact in case some of 64 00:06:41,230 --> 00:06:37,550 you are a little bit confused because 65 00:06:43,660 --> 00:06:41,240 that's a very confusing image if this is 66 00:06:47,470 --> 00:06:43,670 Jupiter and you're all on the earth 67 00:06:50,620 --> 00:06:47,480 you're looking this way okay Jupiter's 68 00:06:53,260 --> 00:06:50,630 spinning like this okay these impacts 69 00:06:56,200 --> 00:06:53,270 this train of comets nuclei are coming 70 00:06:58,600 --> 00:06:56,210 in from the bottom at about an angle 71 00:07:03,010 --> 00:06:58,610 something like this and you can't see 72 00:07:06,460 --> 00:07:03,020 them happen all right there we go let's 73 00:07:08,950 --> 00:07:06,470 take a quick look at the video this is a 74 00:07:11,710 --> 00:07:08,960 very rough reconstruction but you can 75 00:07:15,130 --> 00:07:11,720 see the amazing quality of the images 76 00:07:17,770 --> 00:07:15,140 from the wide field camera and there is 77 00:07:20,860 --> 00:07:17,780 the site it's going to stop on the right 78 00:07:23,260 --> 00:07:20,870 longitude so you can see the pre impact 79 00:07:26,530 --> 00:07:23,270 view there's the Great Red Spot and a 80 00:07:28,540 --> 00:07:26,540 white oval this is the wide field camera 81 00:07:32,200 --> 00:07:28,550 with the planetary camera we're going to 82 00:07:33,820 --> 00:07:32,210 get even better resolution and we'll of 83 00:07:35,140 --> 00:07:33,830 course we'll have a little bit of time 84 00:07:39,460 --> 00:07:35,150 to clean this up and it'll be a really 85 00:07:41,830 --> 00:07:39,470 nice video when we get that chance okay 86 00:07:43,270 --> 00:07:41,840 that's the view very similar not quite 87 00:07:44,710 --> 00:07:43,280 exactly the same is similar to the 88 00:07:47,530 --> 00:07:44,720 impact site you see the Great Red Spot 89 00:07:50,380 --> 00:07:47,540 and you see that little white plume off 90 00:07:54,490 --> 00:07:50,390 to the side that just below and to the 91 00:07:55,840 --> 00:07:54,500 left and if we could go back to the 92 00:07:59,980 --> 00:07:55,850 other one I don't know if that's 93 00:08:02,270 --> 00:07:59,990 possible or not yes we can 94 00:08:04,370 --> 00:08:02,280 we'll look again for the great red spot 95 00:08:06,440 --> 00:08:04,380 in that white spot and you'll see where 96 00:08:12,460 --> 00:08:06,450 the little black thing is next to it the 97 00:08:16,580 --> 00:08:15,470 little bit of dead time okay in the 98 00:08:18,980 --> 00:08:16,590 meantime while they're working on that 99 00:08:20,690 --> 00:08:18,990 continue my story here all right you 100 00:08:22,790 --> 00:08:20,700 could not see the impacts occurring 101 00:08:25,820 --> 00:08:22,800 although the Galileo spacecraft you'll 102 00:08:27,770 --> 00:08:25,830 all remember is in a perfect view to get 103 00:08:29,810 --> 00:08:27,780 some good pictures of that and so that 104 00:08:32,360 --> 00:08:29,820 will be fascinating to see here we go 105 00:08:34,700 --> 00:08:32,370 see the Great Red Spot see the little 106 00:08:37,159 --> 00:08:34,710 white oval and now further on you see 107 00:08:40,670 --> 00:08:37,169 that black splotch it was not there the 108 00:08:43,870 --> 00:08:40,680 day before it's a new feature on Jupiter 109 00:08:47,030 --> 00:08:43,880 and we're going to have 20 more of them 110 00:08:51,200 --> 00:08:47,040 even brighter it's going to be a great 111 00:08:53,090 --> 00:08:51,210 week so I think I'll stop there and let 112 00:08:55,100 --> 00:08:53,100 the rest of my team have some time to 113 00:08:56,660 --> 00:08:55,110 talk ok I'd like to go ahead and 114 00:08:58,850 --> 00:08:56,670 introduce the other members of science 115 00:09:01,430 --> 00:08:58,860 team thank you dr. Hamill to her left 116 00:09:03,350 --> 00:09:01,440 dr.

128 00:09:41,060 --> 00:09:39,410 at the end hi down there Melissa dr. 129 00:09:42,620 --> 00:09:41,070 Melissa McGrath the Space Telescope 130 00:09:45,110 --> 00:09:42,630 Science Institute a member of the faint 131 00:09:48,800 --> 00:09:45,120 object spectrograph and high resolution 132 00:09:52,730 --> 00:09:50,810 and what I'd like to do at this point is 133 00:09:55,100 --> 00:09:52,740 turn it over to hell and just for a few 134 00:09:56,570 --> 00:09:55,110 brief comments and the discussion 135 00:09:59,930 --> 00:09:56,580 members of the team and we'll open it to 136 00:10:01,519 --> 00:09:59,940 Q&A first of all I just like to say it 137 00:10:03,490 --> 00:10:01,529 looks like this comment was not a done 138 00:10:06,440 --> 00:10:03,500 let it ring out to the rest of the world 139 00:10:08,420 --> 00:10:06,450 we've had a wonderful time observing 140 00:10:10,970 --> 00:10:08,430 this fascinating object up until now but 141 00:10:14,840 --> 00:10:10,980 of course it's been highly uncertain as 142 00:10:16,760 --> 00:10:14,850 to how big these pieces are our last we 143 00:10:19,460 --> 00:10:16,770 took to some images of the comment on 144 00:10:21,440 --> 00:10:19,470 Thursday and there were some reports 145 00:10:22,940 --> 00:10:21,450 that the comment was fragmenting but in 146 00:10:24,620 --> 00:10:22,950 fact when you look at the Hubble images 147 00:10:27,700 --> 00:10:24,630 there was no evidence that you know the 148 00:10:31,910 --> 00:10:27,710 kind of the pieces were fragmenting and 149 00:10:34,640 --> 00:10:31,920 the fact that we see a plume coming out 150 00:10:37,040 --> 00:10:34,650 of this explosion it's very strong 151 00:10:39,200 --> 00:10:37,050 evidence that these nuclei are traveling 152 00:10:40,850 --> 00:10:39,210 very deep into Jupiter's atmosphere it's 153 00:10:42,230 --> 00:10:40,860 hard to understand how you have 154 00:10:44,440 --> 00:10:42,240 something's going to shoot out above the 155 00:10:47,240 --> 00:10:44,450 limb by a thousand kilometers or more 156 00:10:48,769 --> 00:10:47,250 unless you had a plume formed an 157 00:10:51,200 --> 00:10:48,779 explosion deep down in the atmosphere 158 00:10:56,240 --> 00:10:51,210 that would be my preliminary guess at 159 00:10:57,950 --> 00:10:56,250 what's going on all right now just for a 160 00:11:00,680 --> 00:10:57,960 couple of moments I know everyone is 161 00:11:02,510 --> 00:11:00,690 prepared here for a lot of questions and 162 00:11:04,340 --> 00:11:02,520 we would like to go ahead and open it up 163 00:11:07,370 --> 00:11:04,350 in just a moment but we do have right 164 00:11:10,160 --> 00:11:07,380 now to show you a video that was taken 165 00:11:12,680 --> 00:11:10,170 just a few minutes actually a few hours 166 00:11:14,960 --> 00:11:12,690 ago during the initial receipt of the 167 00:11:17,300 --> 00:11:14,970 data here at the Hubble Institute so go 168 00:11:23,520 --> 00:11:17,310 ahead and roll the video and we'll see 169 00:11:30,940 --> 00:11:29,710 we're looking for something yeah the 170 00:11:44,760 --> 00:11:30,950 latitude that we're looking for 171 00:11:44,770 --> 00:12:21,970 okay 172 00:12:29,030 --> 00:12:24,710 for the benefit of members in the 173 00:12:31,280 --> 00:12:29,040 gallery here we will have a rerun of the 174 00:12:33,380 --> 00:12:31,290 state later we apologize we had some 175 00:12:35,840 --> 00:12:33,390 tape sync problems the signal went out 176 00:12:38,450 --> 00:12:35,850 on the satellite ok however I understand 177 00:12:40,970 --> 00:12:38,460 so we will replay it and we have some 178 00:12:44,660 --> 00:12:40,980 dubs available for the media that need 179 00:12:48,530 --> 00:12:44,670 that after after the briefing apologize 180 00:12:51,310 --> 00:12:48,540 for that but the or we're all working in 181 00:12:53,000 --> 00:12:51,320 real time here and we do have a few of 182 00:12:54,170 --> 00:12:53,010 difficulties with some technical 183 00:12:55,880 --> 00:12:54,180 equipment as we're trying to work 184 00:12:58,370 --> 00:12:55,890 through but I'd like to open it up to 185 00:13:00,800 --> 00:12:58,380 questions and answers if we're all ready 186 00:13:02,840 --> 00:13:00,810 for that here and the Institute in 187 00:13:04,910 --> 00:13:02,850 Baltimore and please wait for the 188 00:13:08,860 --> 00:13:04,920 microphone and state your name and 189 00:13:13,940 --> 00:13:08,870 affiliation any questions in front row 190 00:13:15,740 --> 00:13:13,950 wait for the microphone Linda Howe 191 00:13:20,000 --> 00:13:15,750 chancellor communications Philadelphia 192 00:13:22,370 --> 00:13:20,010 in one of the email releases out here it 193 00:13:24,830 --> 00:13:22,380 said that the Nordic optical telescope 194 00:13:27,800 --> 00:13:24,840 in la palma in the Canary Islands had 195 00:13:31,310 --> 00:13:27,810 reported that two hours after the first 196 00:13:34,580 --> 00:13:31,320 bright image was seen that there a black 197 00:13:37,340 --> 00:13:34,590 dot became visible in the video image of 198 00:13:40,280 --> 00:13:37,350 Jupiter at exactly the same position of 199 00:13:43,550 --> 00:13:40,290 this bright impact what could make this 200 00:13:49,580 --> 00:13:43,560 black dot be seen two hours after this 201 00:13:55,950 --> 00:13:52,560 pretty simple part of the part of the 202 00:13:58,940 --> 00:13:55,960 answer to that is pretty simple the 203 00:14:01,650 --> 00:13:58,950 impact occurred at a certain time we saw 204 00:14:06,360 --> 00:14:01,660 apparently a plume on the on the limb of 205 00:14:10,110 --> 00:14:06,370 Jupiter at that time and then as Jupiter 206 00:14:13,230 --> 00:14:10,120 rotated into our rotated around as it 207 00:14:15,990 --> 00:14:13,240 does the impact site came into our view 208 00:14:18,390 --> 00:14:16,000 and that impact site is a place where we 209 00:14:20,700 --> 00:14:18,400 now see dark material and so is Jupiter 210 00:14:22,020 --> 00:14:20,710 continues to rotate that's coming more 211 00:14:23,370 --> 00:14:22,030 and more into our field of view and I 212 00:14:25,440 --> 00:14:23,380 think the fact that they're reporting 213 00:14:28,290 --> 00:14:25,450 seeing about two hours after the initial 214 00:14:30,780 --> 00:14:28,300 plume is that initially it was it was 215 00:14:32,460 --> 00:14:30,790 close to the the edge of where the 216 00:14:34,680 --> 00:14:32,470 sunlight is and very difficult to see on 217 00:14:37,470 --> 00:14:34,690 the edge of Jupiter and I think their 218 00:14:39,240 --> 00:14:37,480 camera system was probably not good 219 00:14:42,210 --> 00:14:39,250 enough had didn't have enough resolution 220 00:14:44,130 --> 00:14:42,220 to see that until it rotated far enough 221 00:14:47,130 --> 00:14:44,140 into interview that they could pick it 222 00:14:48,570 --> 00:14:47,140 up whereas we saw it essentially 223 00:14:50,640 --> 00:14:48,580 immediately or at least in the next 224 00:14:52,950 --> 00:14:50,650 orbit and there's also the question that 225 00:14:55,860 --> 00:14:52,960 may be part of your question is why are 226 00:14:57,930 --> 00:14:55,870 we seeing black material and that's the 227 00:15:00,420 --> 00:14:57,940 more interesting question I don't think 228 00:15:03,300 --> 00:15:00,430 anybody expected us to see black 229 00:15:06,150 --> 00:15:03,310 material I certainly didn't I expected 230 00:15:07,800 --> 00:15:06,160 that we would see perhaps bright 231 00:15:11,340 --> 00:15:07,810 material in the methane image which we 232 00:15:14,040 --> 00:15:11,350 do see but in other images I thought we 233 00:15:15,990 --> 00:15:14,050 might not see anything the reit I'm 234 00:15:19,230 --> 00:15:16,000 going to speculate now about why we 235 00:15:21,240 --> 00:15:19,240 might be seeing black material there's a 236 00:15:24,150 --> 00:15:21,250 couple of possibilities and I think what 237 00:15:26,610 --> 00:15:24,160 we're seeing here our particles either 238 00:15:28,830 --> 00:15:26,620 from the comet itself or particles that 239 00:15:31,560 --> 00:15:28,840 may have been dredged up from deeper and 240 00:15:34,800 --> 00:15:31,570 Jupiter's atmosphere if the particles 241 00:15:36,780 --> 00:15:34,810 are from the comet they could be partly 242 00:15:40,580 --> 00:15:36,790 silicate particles and maybe a little 243 00:15:43,230 --> 00:15:40,590 bit of iron in there they could also be 244 00:15:45,330 --> 00:15:43,240 carbonaceous material which normally is 245 00:15:48,870 --> 00:15:45,340 black the trouble with that explanation 246 00:15:51,090 --> 00:15:48,880 though is that we expect that material 247 00:15:54,300 --> 00:15:51,100 to have undergone very high temperatures 248 00:15:56,700 --> 00:15:54,310 something like 40,000 degrees Kelvin at 249 00:15:58,920 --> 00:15:56,710 those temperatures any particles would 250 00:16:00,060 --> 00:15:58,930 vaporize the carbon would probably go 251 00:16:02,790 --> 00:16:00,070 into 252 00:16:06,200 --> 00:16:02,800 carbon monoxide gas and we wouldn't see 253 00:16:09,480 --> 00:16:06,210 it that's one reason it's very puzzling 254 00:16:12,510 --> 00:16:09,490 as the fireball would rise out of the 255 00:16:15,000 --> 00:16:12,520 atmosphere the plume arises everything 256 00:16:17,340 --> 00:16:15,010 cools very quickly and out of that 257 00:16:20,130 --> 00:16:17,350 cooling cloud you expect things to 258 00:16:21,960 --> 00:16:20,140 condense like silicates and maybe even 259 00:16:23,880 --> 00:16:21,970 some of these carbonaceous particles if 260 00:16:26,460 --> 00:16:23,890 they're still around and finally Isis 261 00:16:28,800 --> 00:16:26,470 like water or ammonia ice we expect 262 00:16:31,440 --> 00:16:28,810 would condense as a as the thing cools 263 00:16:33,660 --> 00:16:31,450 enough now Isis we expect to be white so 264 00:16:37,440 --> 00:16:33,670 again we're puzzled why are we seeing 265 00:16:41,970 --> 00:16:37,450 dark stuff and going further in 266 00:16:43,440 --> 00:16:41,980 speculation we expect that in Jupiter's 267 00:16:45,330 --> 00:16:43,450 atmosphere there's a lot of sulfur 268 00:16:47,820 --> 00:16:45,340 although we haven't observed it 269 00:16:49,800 --> 00:16:47,830 spectroscopically yet we think there is 270 00:16:52,560 --> 00:16:49,810 we think that if there's material 271 00:16:54,210 --> 00:16:52,570 dredged up from the atmosphere it might 272 00:16:57,960 --> 00:16:54,220 be rich in sulfur as well as other 273 00:17:02,400 --> 00:16:57,970 things water and ammonia sulfur can can 274 00:17:04,500 --> 00:17:02,410 form colored compounds and just what 275 00:17:07,890 --> 00:17:04,510 kind of compounds would form in this 276 00:17:10,500 --> 00:17:07,900 situation I'm not prepared to say and so 277 00:17:12,929 --> 00:17:10,510 I'm guessing that maybe sulfur sulfur 278 00:17:16,140 --> 00:17:12,939 ions in some form are contributing to 279 00:17:18,390 --> 00:17:16,150 this dark stuff just quick follow-up in 280 00:17:21,000 --> 00:17:18,400 addition to the mystery of the color I 281 00:17:23,699 --> 00:17:21,010 also wondered if seeing this two hours 282 00:17:25,980 --> 00:17:23,709 after after perhaps the initial impact 283 00:17:28,530 --> 00:17:25,990 does that mean that we could be seeing 284 00:17:31,530 --> 00:17:28,540 the residue of these impacts for much 285 00:17:32,970 --> 00:17:31,540 longer than anyone ever thought I'm not 286 00:17:37,200 --> 00:17:32,980 sure about longer than anyone ever 287 00:17:38,970 --> 00:17:37,210 thought because in my thinking I expect 288 00:17:40,800 --> 00:17:38,980 that we should be able to see the 289 00:17:43,350 --> 00:17:40,810 residuals these particles in the 290 00:17:45,780 --> 00:17:43,360 stratosphere for possibly a year or 291 00:17:50,190 --> 00:17:45,790 longer and in fact when I proposed to do 292 00:17:52,980 --> 00:17:50,200 this observing it was to look over long 293 00:17:54,840 --> 00:17:52,990 timescales to use these particles as 294 00:17:57,720 --> 00:17:54,850 tracers of the stratospheric motion I 295 00:18:00,300 --> 00:17:57,730 see this I viewed this event is possibly 296 00:18:02,550 --> 00:18:00,310 analogous to on earth when there is a 297 00:18:05,250 --> 00:18:02,560 large eruption from like el chicano 298 00:18:06,960 --> 00:18:05,260 Pinatubo volcanic eruptions put 299 00:18:08,880 --> 00:18:06,970 particles high in the atmosphere where 300 00:18:11,310 --> 00:18:08,890 there were the stability of the 301 00:18:12,659 --> 00:18:11,320 atmosphere is is the atmosphere is very 302 00:18:15,239 --> 00:18:12,669 stable and there 303 00:18:17,460 --> 00:18:15,249 or particles can reside there for a long 304 00:18:19,919 --> 00:18:17,470 time and in fact on the earth this is 305 00:18:21,419 --> 00:18:19,929 one way we learn about the dynamics and 306 00:18:23,789 --> 00:18:21,429 circulation of the stratosphere is by 307 00:18:26,460 --> 00:18:23,799 watching how these particles spread with 308 00:18:29,009 --> 00:18:26,470 time and so I saw this is the first 309 00:18:31,470 --> 00:18:29,019 opportunity ever of doing this kind of 310 00:18:32,909 --> 00:18:31,480 thing on Jupiter and the timescales for 311 00:18:35,639 --> 00:18:32,919 spreading on earth in the stratosphere 312 00:18:38,519 --> 00:18:35,649 are over the order of a year or so and I 313 00:18:42,720 --> 00:18:38,529 expect that we may still be seeing stuff 314 00:18:45,090 --> 00:18:42,730 here from now from these events right 315 00:18:46,379 --> 00:18:45,100 here at second row I wait for the mic 316 00:18:48,960 --> 00:18:46,389 please and also I'd like to ask the 317 00:18:52,049 --> 00:18:48,970 panel members to introduce yourself also 318 00:18:53,789 --> 00:18:52,059 to to help us out here thank you Bob 319 00:18:56,430 --> 00:18:53,799 cook Newsday I understand one of the 320 00:18:58,109 --> 00:18:56,440 really interesting possibilities was the 321 00:18:59,970 --> 00:18:58,119 comments might get deep enough to punch 322 00:19:06,509 --> 00:18:59,980 through the water clouds if they exist 323 00:19:09,840 --> 00:19:06,519 you think that might have happened one 324 00:19:12,779 --> 00:19:09,850 of the sorry Keith know from Space 325 00:19:14,070 --> 00:19:12,789 Telescope Science Institute one of the 326 00:19:15,930 --> 00:19:14,080 key things and all the spectroscopic 327 00:19:18,180 --> 00:19:15,940 observations that will be looking for 328 00:19:21,389 --> 00:19:18,190 both with Hubble Space Telescope and 329 00:19:22,590 --> 00:19:21,399 ground-based telescopes or molecules 330 00:19:26,009 --> 00:19:22,600 that are dredged up from the deep 331 00:19:28,739 --> 00:19:26,019 atmosphere and as you said the water 332 00:19:31,259 --> 00:19:28,749 cloud would be one of the things that 333 00:19:34,320 --> 00:19:31,269 would be looking for very keenly the 334 00:19:36,029 --> 00:19:34,330 reason for that is that if we see a huge 335 00:19:37,379 --> 00:19:36,039 increase in the amount of water more 336 00:19:40,560 --> 00:19:37,389 than could have come from the comet 337 00:19:42,180 --> 00:19:40,570 itself will know something about the 338 00:19:43,889 --> 00:19:42,190 energy of the impactor and how deep it 339 00:19:47,909 --> 00:19:43,899 penetrated into the atmosphere so we'll 340 00:19:49,529 --> 00:19:47,919 be using these molecular clues the 341 00:19:52,080 --> 00:19:49,539 debris from the comet and the stuff 342 00:19:54,960 --> 00:19:52,090 churned up from the atmosphere to tell 343 00:19:56,340 --> 00:19:54,970 us things about size of the comet how 344 00:20:00,710 --> 00:19:56,350 deeply penetrated into the atmosphere 345 00:20:04,739 --> 00:20:00,720 and as Bob alluded to before possibly 346 00:20:06,239 --> 00:20:04,749 allow us to see molecules that until now 347 00:20:15,570 --> 00:20:06,249 have been too deep in Jupiter's 348 00:20:19,480 --> 00:20:17,919 in the past few weeks we've been told 349 00:20:22,210 --> 00:20:19,490 that amateur astronomers have little 350 00:20:23,919 --> 00:20:22,220 chance of seeing this event does what 351 00:20:25,779 --> 00:20:23,929 you've seen so far make you a little 352 00:20:28,090 --> 00:20:25,789 more optimistic about with the unwashed 353 00:20:36,999 --> 00:20:28,100 masses or the semi wash matches washed 354 00:20:37,960 --> 00:20:37,009 message might say I'm Melissa McGrath 355 00:20:40,659 --> 00:20:37,970 from the Space Telescope Science 356 00:20:43,360 --> 00:20:40,669 Institute the most dramatic results 357 00:20:45,909 --> 00:20:43,370 we've seen so far brightness wise have 358 00:20:48,310 --> 00:20:45,919 actually been in the infrared and so 359 00:20:50,259 --> 00:20:48,320 unless they had infrared instruments I 360 00:20:52,509 --> 00:20:50,269 think actually in the visible it's 361 00:20:55,690 --> 00:20:52,519 unlikely that this would have been seen 362 00:20:58,090 --> 00:20:55,700 Hubble saw it because it has such good 363 00:21:01,090 --> 00:20:58,100 resolution and when you see the images 364 00:21:03,730 --> 00:21:01,100 tomorrow of the first plume that we 365 00:21:06,369 --> 00:21:03,740 detected it was very small very small 366 00:21:08,379 --> 00:21:06,379 and very close to the loom and because 367 00:21:10,539 --> 00:21:08,389 Jupiter's so bright that's very 368 00:21:13,570 --> 00:21:10,549 difficult to see with anything but 369 00:21:16,749 --> 00:21:13,580 Hubble so I imagine I mean we know that 370 00:21:18,070 --> 00:21:16,759 the B impact is at ten-thirty and some 371 00:21:20,080 --> 00:21:18,080 of us would actually like to go outside 372 00:21:22,690 --> 00:21:20,090 with our binoculars at ten-thirty and 373 00:21:25,180 --> 00:21:22,700 look because bees a lot bigger than a 374 00:21:27,129 --> 00:21:25,190 and so are a lot brighter than a so we 375 00:21:29,740 --> 00:21:27,139 think that means a lot bigger so you 376 00:21:31,509 --> 00:21:29,750 know it wasn't so bright in a and the 377 00:21:33,790 --> 00:21:31,519 visible but he may be brighter and I 378 00:21:38,600 --> 00:21:33,800 think we should all go work 379 00:21:42,050 --> 00:21:38,610 here at second rope it please state your 380 00:21:44,240 --> 00:21:42,060 name and affiliation Clint achoo San 381 00:21:48,200 --> 00:21:44,250 Jose Mercury News I'm a puzzle about how 382 00:21:49,820 --> 00:21:48,210 to describe this thing to readers what 383 00:21:51,980 --> 00:21:49,830 was it dark was it bright or what 384 00:21:54,020 --> 00:21:51,990 because some of the email messages were 385 00:21:56,270 --> 00:21:54,030 describing something right enough at 386 00:21:58,460 --> 00:21:56,280 certain wavelengths of light that it out 387 00:22:00,710 --> 00:21:58,470 shown anything else on Jupiter from the 388 00:22:03,020 --> 00:22:00,720 the things that look like polar caps in 389 00:22:06,560 --> 00:22:03,030 the methane band to anything else and 390 00:22:08,360 --> 00:22:06,570 even now shown I oh and then then you're 391 00:22:10,730 --> 00:22:08,370 talking about I guess in the visible 392 00:22:12,830 --> 00:22:10,740 wavelengths of thing is dark and so I 393 00:22:14,360 --> 00:22:12,840 don't know if I tell people that this is 394 00:22:15,950 --> 00:22:14,370 a real bright thing and then out shown 395 00:22:17,870 --> 00:22:15,960 everything am I really misleading them 396 00:22:20,360 --> 00:22:17,880 and what is the significance of this 397 00:22:22,220 --> 00:22:20,370 methane band or the implement the 398 00:22:23,750 --> 00:22:22,230 infrared bands that you're observing 399 00:22:24,770 --> 00:22:23,760 what are you seeing that that is 400 00:22:29,030 --> 00:22:24,780 different from what you're seeing in 401 00:22:31,430 --> 00:22:29,040 visible light i'm john clark university 402 00:22:33,470 --> 00:22:31,440 of michigan let me start with the 403 00:22:36,500 --> 00:22:33,480 infrared bands in the infrared you're 404 00:22:38,270 --> 00:22:36,510 looking you can think of it as a heat as 405 00:22:40,070 --> 00:22:38,280 much as it is light as you go farther 406 00:22:42,110 --> 00:22:40,080 into the infrared you sampling lower 407 00:22:43,760 --> 00:22:42,120 temperatures and these were at 408 00:22:46,760 --> 00:22:43,770 temperatures that are much hotter than 409 00:22:48,110 --> 00:22:46,770 what we have here in this room there 410 00:22:49,700 --> 00:22:48,120 were two wavelengths of about two 411 00:22:51,920 --> 00:22:49,710 microns where it appeared very bright 412 00:22:53,960 --> 00:22:51,930 and there it appeared bright because 413 00:22:56,060 --> 00:22:53,970 that one localized region was much 414 00:22:58,250 --> 00:22:56,070 hotter than the tops of Jupiter's clouds 415 00:23:00,740 --> 00:22:58,260 overall so it appeared to have a high 416 00:23:02,480 --> 00:23:00,750 contrast when we look at these visible 417 00:23:04,400 --> 00:23:02,490 wavelengths we're looking at sun light 418 00:23:06,890 --> 00:23:04,410 that's reflected from the cloud tops and 419 00:23:09,260 --> 00:23:06,900 they're there as much there's relatively 420 00:23:11,600 --> 00:23:09,270 less contrast here than you see infra 421 00:23:13,880 --> 00:23:11,610 red but there's more information about 422 00:23:16,400 --> 00:23:13,890 the disturbance because we have the 423 00:23:18,710 --> 00:23:16,410 better resolution in the methane band 424 00:23:21,140 --> 00:23:18,720 filter in particular we're looking at a 425 00:23:23,540 --> 00:23:21,150 particular wavelength of light of Sun 426 00:23:26,090 --> 00:23:23,550 light that is absorbed by gas methane 427 00:23:28,340 --> 00:23:26,100 gas in Jupiter's atmosphere and their 428 00:23:30,710 --> 00:23:28,350 Jupiter overall the pier is much darker 429 00:23:32,330 --> 00:23:30,720 because the the sunlight is being 430 00:23:34,820 --> 00:23:32,340 absorbed by the gas that's normally in 431 00:23:36,770 --> 00:23:34,830 the atmosphere and there the the comet 432 00:23:38,990 --> 00:23:36,780 fragment appears relatively bright just 433 00:23:41,930 --> 00:23:39,000 as a matter of contrast so it's a 434 00:23:43,490 --> 00:23:41,940 relative brightness thing there we also 435 00:23:46,860 --> 00:23:43,500 will be getting images in the 436 00:23:49,360 --> 00:23:46,870 ultraviolet wavelengths the first 437 00:23:51,520 --> 00:23:49,370 well about eight or ten hours will be 438 00:23:53,530 --> 00:23:51,530 taken and I'll come down tomorrow and in 439 00:23:55,210 --> 00:23:53,540 the ultraviolet which is my main 440 00:23:56,680 --> 00:23:55,220 interest will be observing the very 441 00:23:59,440 --> 00:23:56,690 highest parts of Jupiter's atmosphere 442 00:24:01,600 --> 00:23:59,450 and from what we've seen already in the 443 00:24:04,510 --> 00:24:01,610 lower parts I'm looking forward to 444 00:24:12,040 --> 00:24:04,520 seeing images and we'll get those 445 00:24:13,510 --> 00:24:12,050 tomorrow about noon in the front bill 446 00:24:14,980 --> 00:24:13,520 Hartwick CBS and I might have missed 447 00:24:17,500 --> 00:24:14,990 this earlier if I did I apologize can 448 00:24:22,300 --> 00:24:17,510 anyone give us a scale for the structure 449 00:24:25,410 --> 00:24:22,310 that we're seeing here how long have to 450 00:24:29,500 --> 00:24:25,420 be in fact this was and how big this is 451 00:24:33,540 --> 00:24:29,510 and I have a follow the box that you see 452 00:24:36,490 --> 00:24:33,550 the zoom box is about to earth diameters 453 00:24:39,070 --> 00:24:36,500 so that that structure that you're 454 00:24:43,600 --> 00:24:39,080 seeing that circular pattern is about 455 00:24:46,180 --> 00:24:43,610 the size of the earth Jupiter's a big 456 00:24:52,270 --> 00:24:46,190 planet remember that this is the a 457 00:24:55,720 --> 00:24:52,280 impact G is much brighter my next 458 00:24:56,740 --> 00:24:55,730 question actually a whole bunch of 459 00:24:59,410 --> 00:24:56,750 questions but I don't suppose that 460 00:25:01,330 --> 00:24:59,420 looking at this raw data that we know 461 00:25:04,930 --> 00:25:01,340 any have any better guest a minister how 462 00:25:06,370 --> 00:25:04,940 deep is this thing plunge don't you well 463 00:25:09,220 --> 00:25:06,380 as i said the fact that you see the 464 00:25:11,530 --> 00:25:09,230 plume means that you know you probably 465 00:25:12,970 --> 00:25:11,540 went very deep and produced a fireball 466 00:25:16,150 --> 00:25:12,980 like the theorists have been describing 467 00:25:17,860 --> 00:25:16,160 and you know we have a we have a plume 468 00:25:20,320 --> 00:25:17,870 that extends out more than thousand 469 00:25:24,070 --> 00:25:20,330 kilometers above the normal limb of the 470 00:25:25,360 --> 00:25:24,080 planet so i think that's that's pretty 471 00:25:28,720 --> 00:25:25,370 good evidence that you know these 472 00:25:30,940 --> 00:25:28,730 impacts really are 200,000 megatons of 473 00:25:33,519 --> 00:25:30,950 tnt or more 474 00:25:35,919 --> 00:25:33,529 did it does this match what you would 475 00:25:37,269 --> 00:25:35,929 expect from the model how deep you you 476 00:25:40,149 --> 00:25:37,279 thought you would get to get this kind 477 00:25:43,930 --> 00:25:40,159 of effect there were so many models you 478 00:25:45,430 --> 00:25:43,940 can imagine anything by the shoemaker's 479 00:25:46,990 --> 00:25:45,440 earlier tonight I mean is this matching 480 00:25:48,610 --> 00:25:47,000 pretty much with those that we missed 481 00:25:50,649 --> 00:25:48,620 the priest combo we were watching the 482 00:25:52,539 --> 00:25:50,659 integers gonna we can't tell you that 483 00:25:54,279 --> 00:25:52,549 when the shoemaker's saw the images jean 484 00:25:56,409 --> 00:25:54,289 shoemaker was extremely happy so 485 00:25:57,940 --> 00:25:56,419 apparently that's pretty good and the 486 00:25:59,740 --> 00:25:57,950 last question for me is how surprised 487 00:26:01,960 --> 00:25:59,750 were you people are really well you 488 00:26:05,980 --> 00:26:01,970 couldn't see that video we were pretty 489 00:26:08,830 --> 00:26:05,990 darn surprised this this is in my dreams 490 00:26:11,250 --> 00:26:08,840 the kind of stuff we saw we we couldn't 491 00:26:19,930 --> 00:26:11,260 have gotten any better no this is 492 00:26:23,259 --> 00:26:19,940 incredible next question second row Ron 493 00:26:25,690 --> 00:26:23,269 Cowan science news is it an agreement 494 00:26:29,950 --> 00:26:25,700 now about when this it when they 495 00:26:32,919 --> 00:26:29,960 actually hit Jupiter or we're working on 496 00:26:35,740 --> 00:26:32,929 that right now and would you mean would 497 00:26:38,440 --> 00:26:35,750 you say Hubble's saw this a minute after 498 00:26:46,299 --> 00:26:38,450 a few minutes after 30 minutes after you 499 00:26:48,430 --> 00:26:46,309 need our own a nap well that is but we 500 00:26:52,570 --> 00:26:48,440 saw the image on the limb and that was 501 00:26:55,389 --> 00:26:52,580 probably within 10 minutes 5 minutes 5 502 00:26:57,159 --> 00:26:55,399 to 10 minutes yeah we've we've and some 503 00:26:59,610 --> 00:26:57,169 of the ones later on in the week are 504 00:27:01,810 --> 00:26:59,620 actually impacting closer to the limb 505 00:27:04,799 --> 00:27:01,820 summit and they are brighter than this 506 00:27:07,240 --> 00:27:04,809 you know I would say one thing that G 507 00:27:12,580 --> 00:27:07,250 probably has an energy that's about 25 508 00:27:15,909 --> 00:27:12,590 times as high as a I'm just checking in 509 00:27:17,799 --> 00:27:15,919 that black spot there is the diameter of 510 00:27:21,220 --> 00:27:17,809 Earth is that what you're saying well 511 00:27:24,070 --> 00:27:21,230 the box you can fit to earth diameters 512 00:27:25,899 --> 00:27:24,080 in that box what about the black spot 513 00:27:27,789 --> 00:27:25,909 which is the that would be half the 514 00:27:30,049 --> 00:27:27,799 earth diannemurray but that's what 515 00:27:34,110 --> 00:27:30,059 everybody within yes 516 00:27:36,150 --> 00:27:34,120 third to a half and lastly what's again 517 00:27:40,110 --> 00:27:36,160 at the moment what's the best estimate 518 00:27:49,180 --> 00:27:40,120 for the diameter of fragment a between 519 00:27:55,490 --> 00:27:52,730 hi I'm nolol McCormick with space x is 520 00:27:57,740 --> 00:27:55,500 there they took the image off the with 521 00:28:02,529 --> 00:27:57,750 acoustic energy be visible from these 522 00:28:06,289 --> 00:28:02,539 strikes well mark Marley would think so 523 00:28:08,810 --> 00:28:06,299 we have a lot of debate about that the 524 00:28:11,480 --> 00:28:08,820 dark area of way from the you know that 525 00:28:13,880 --> 00:28:11,490 surrounds this the darkest area could 526 00:28:17,450 --> 00:28:13,890 that be that type of energy we've been 527 00:28:19,610 --> 00:28:17,460 debating it my preference is to say no I 528 00:28:22,340 --> 00:28:19,620 think it's very difficult to make 529 00:28:24,289 --> 00:28:22,350 something dark on Jupiter from a 530 00:28:27,140 --> 00:28:24,299 pressure wave of something like that I 531 00:28:29,210 --> 00:28:27,150 think I think the likelihood is that 532 00:28:31,760 --> 00:28:29,220 anything thats dark on Jupiter is caused 533 00:28:34,610 --> 00:28:31,770 by particles in the atmosphere they're 534 00:28:36,590 --> 00:28:34,620 absorbing light but as I say this is far 535 00:28:39,230 --> 00:28:36,600 from being settled and I think time will 536 00:28:41,659 --> 00:28:39,240 tell we also have the better data set 537 00:28:43,610 --> 00:28:41,669 that this to look for those kind of 538 00:28:45,890 --> 00:28:43,620 phenomena and furthermore those 539 00:28:48,950 --> 00:28:45,900 phenomena are most likely to be detected 540 00:28:52,190 --> 00:28:48,960 in infrared imaging because those waves 541 00:28:54,470 --> 00:28:52,200 are temperature changes and so those 542 00:28:57,169 --> 00:28:54,480 that's the primary way to detect them 543 00:29:00,350 --> 00:28:57,179 we're here seeing sort of a secondary 544 00:29:01,940 --> 00:29:00,360 effect from the temperature change so it 545 00:29:04,310 --> 00:29:01,950 will be very interesting to see what the 546 00:29:09,160 --> 00:29:04,320 infrared telescopes around the world see 547 00:29:16,100 --> 00:29:09,170 from those brighter impacts nice 548 00:29:19,040 --> 00:29:16,110 out here Jim Reston for Esquire does 549 00:29:21,049 --> 00:29:19,050 this first image give us any insight 550 00:29:27,500 --> 00:29:21,059 into the question of whether there will 551 00:29:30,650 --> 00:29:27,510 be a permanent cyclone on Jupiter it's 552 00:29:32,810 --> 00:29:30,660 too soon to tell you and when I when 553 00:29:39,560 --> 00:29:32,820 will we start to get some fix on that 554 00:29:45,130 --> 00:29:39,570 question months no days days and he said 555 00:29:52,940 --> 00:29:49,580 okay we're going to go to a center right 556 00:29:58,409 --> 00:29:52,950 now for a question not sure which one 557 00:30:02,159 --> 00:30:00,210 perhaps are not on the line right at the 558 00:30:09,910 --> 00:30:02,169 moment we'll take another one here in 559 00:30:15,950 --> 00:30:13,280 will be my name is senior bandage guy I 560 00:30:17,660 --> 00:30:15,960 think this question with dr. McGrath and 561 00:30:20,450 --> 00:30:17,670 do you see some change at the plasma 562 00:30:22,850 --> 00:30:20,460 torus or the oral at Jupiter in this 563 00:30:24,440 --> 00:30:22,860 stage actually um we don't do 564 00:30:26,930 --> 00:30:24,450 observations with the Hubble Space 565 00:30:29,420 --> 00:30:26,940 Telescope of the torus until the end of 566 00:30:33,290 --> 00:30:29,430 the week we will do some observations 567 00:30:36,020 --> 00:30:33,300 with the iue satellite on tuesday i 568 00:30:37,960 --> 00:30:36,030 believe it is of the eye of horus one 569 00:30:41,030 --> 00:30:37,970 interesting thing that was reported 570 00:30:43,780 --> 00:30:41,040 closely related to that is that some 571 00:30:47,330 --> 00:30:43,790 japanese observers radio observers 572 00:30:49,910 --> 00:30:47,340 apparently saw a tenfold increase in the 573 00:30:52,220 --> 00:30:49,920 DECA metric radio emission from Jupiter 574 00:30:53,690 --> 00:30:52,230 well before the impact so there is some 575 00:30:55,730 --> 00:30:53,700 evidence that there was a large 576 00:30:57,290 --> 00:30:55,740 disturbance in the magnetosphere so I 577 00:30:59,000 --> 00:30:57,300 think we have high hopes that there may 578 00:31:02,150 --> 00:30:59,010 also be disturbance to the Eye of Horus 579 00:31:04,970 --> 00:31:02,160 there haven't been any for oral images 580 00:31:06,560 --> 00:31:04,980 with HST since the impact but there will 581 00:31:09,500 --> 00:31:06,570 be and we should be able to answer that 582 00:31:13,160 --> 00:31:09,510 question soon those first of all images 583 00:31:14,900 --> 00:31:13,170 will come down tomorrow we're going to 584 00:31:17,210 --> 00:31:14,910 go to Kennedy Space Center now for a 585 00:31:19,610 --> 00:31:17,220 question there and we'll come back after 586 00:31:22,910 --> 00:31:19,620 that go ahead state your name and 587 00:31:25,730 --> 00:31:22,920 affiliation please visit filter on earth 588 00:31:29,030 --> 00:31:25,740 news can you establish a minimum meth 589 00:31:31,250 --> 00:31:29,040 now for the piece and assuming the rough 590 00:31:33,050 --> 00:31:31,260 density that you've been assuming just 591 00:31:34,550 --> 00:31:33,060 how much kinetic energy was involved in 592 00:31:36,230 --> 00:31:34,560 it she can't you establish any lower 593 00:31:39,200 --> 00:31:36,240 limit now that would have been apart for 594 00:31:41,930 --> 00:31:39,210 just the fact that you thought I think 595 00:31:45,020 --> 00:31:41,940 the fact that we see the plume and 596 00:31:47,540 --> 00:31:45,030 apparently some very hot stuff which 597 00:31:50,270 --> 00:31:47,550 seems to you know back up some of the 598 00:31:54,470 --> 00:31:50,280 models or some of the models predicted 599 00:31:58,550 --> 00:31:54,480 this kind of phenomena if the impactor 600 00:32:00,020 --> 00:31:58,560 was about a kilometer in size in fact 601 00:32:01,760 --> 00:32:00,030 that we see something you know close to 602 00:32:03,260 --> 00:32:01,770 that indicates to me that we're talking 603 00:32:06,500 --> 00:32:03,270 about something roughly a kilometer in 604 00:32:11,390 --> 00:32:06,510 size which means roughly 200,000 605 00:32:13,760 --> 00:32:11,400 megatons of equivalent TNT but whether 606 00:32:16,760 --> 00:32:13,770 or not it's you know one kilometer 607 00:32:19,670 --> 00:32:16,770 versus two kilometer versus even 500 608 00:32:20,659 --> 00:32:19,680 meters I think that you know I couldn't 609 00:32:22,489 --> 00:32:20,669 say that right 610 00:32:27,830 --> 00:32:22,499 I couldn't you know tell you which one 611 00:32:30,320 --> 00:32:27,840 versus the other at this point follow up 612 00:32:32,239 --> 00:32:30,330 please so I remember the spectrograph 613 00:32:34,070 --> 00:32:32,249 the teams were you able to do any 614 00:32:36,379 --> 00:32:34,080 quicker special wrath of the area or 615 00:32:39,769 --> 00:32:36,389 that's doing the future and what would 616 00:32:45,499 --> 00:32:39,779 you expect that 889 nanometers at the 617 00:32:47,060 --> 00:32:45,509 methane line the first spectra we've 618 00:32:49,460 --> 00:32:47,070 gotten base line spectra over the last 619 00:32:51,019 --> 00:32:49,470 few days but the first spectra we're 620 00:32:53,539 --> 00:32:51,029 going to get will be of the G impact 621 00:32:55,759 --> 00:32:53,549 site and that's going to be on Monday 622 00:32:58,549 --> 00:32:55,769 morning while I Specter are going to be 623 00:33:00,399 --> 00:32:58,559 ultraviolet spectra visible wavelengths 624 00:33:03,169 --> 00:33:00,409 inspector will be done from ground-based 625 00:33:05,239 --> 00:33:03,179 telescopes and infrared spectra will be 626 00:33:07,489 --> 00:33:05,249 taken also from ground-based telescopes 627 00:33:09,710 --> 00:33:07,499 so we are doing what Hubble can uniquely 628 00:33:14,799 --> 00:33:09,720 do and that is obtained the 629 00:33:18,919 --> 00:33:17,149 what can you tell us that anybody know 630 00:33:20,180 --> 00:33:18,929 about those these other images I realize 631 00:33:21,529 --> 00:33:20,190 that you're just showing us the blue one 632 00:33:23,299 --> 00:33:21,539 where she took several different 633 00:33:27,470 --> 00:33:23,309 snapshots in different ways like that 634 00:33:30,320 --> 00:33:27,480 far as how different do they appear and 635 00:33:32,330 --> 00:33:30,330 where you get a false color or an 636 00:33:35,899 --> 00:33:32,340 imitation full color picture by the 637 00:33:40,999 --> 00:33:35,909 morning well I'd like to get a little 638 00:33:44,029 --> 00:33:41,009 sleep tonight at at most of the 639 00:33:46,759 --> 00:33:44,039 wavelengths that we looked at the the 640 00:33:49,759 --> 00:33:46,769 feature appears to very similar to what 641 00:33:52,330 --> 00:33:49,769 we short were showing in the blue so at 642 00:33:55,879 --> 00:33:52,340 almost all the wavelengths this dark 643 00:33:58,549 --> 00:33:55,889 streak with that circular pattern around 644 00:34:00,950 --> 00:33:58,559 it is what you see the only exception is 645 00:34:02,479 --> 00:34:00,960 the methane band wavelengths and as I 646 00:34:04,820 --> 00:34:02,489 said before that appears to be a 647 00:34:07,070 --> 00:34:04,830 complete negative what you see dark is 648 00:34:09,799 --> 00:34:07,080 bright so you see a little bright streak 649 00:34:13,069 --> 00:34:09,809 with a little bright swirl around the 650 00:34:15,889 --> 00:34:13,079 bottom of it it's too soon to talk about 651 00:34:18,319 --> 00:34:15,899 colors of this thing yet because we just 652 00:34:20,569 --> 00:34:18,329 simply have not had the time to work on 653 00:34:23,690 --> 00:34:20,579 it we will probably be trying to put 654 00:34:25,639 --> 00:34:23,700 together some color reconstructions I 655 00:34:28,200 --> 00:34:25,649 can't guarantee that will be tomorrow 656 00:34:30,990 --> 00:34:28,210 morning we'll do the best we can 657 00:34:32,899 --> 00:34:31,000 like to come back to these the telescope 658 00:34:38,220 --> 00:34:32,909 Institute here for some more questions 659 00:34:40,230 --> 00:34:38,230 in front Tyga I'm irani BBC television 660 00:34:42,000 --> 00:34:40,240 it's quite clear that the science team 661 00:34:43,560 --> 00:34:42,010 is very excited about this and you guys 662 00:34:45,780 --> 00:34:43,570 are going to have a lot of data to go 663 00:34:47,190 --> 00:34:45,790 through for months to come but what's in 664 00:34:49,560 --> 00:34:47,200 it for the guy on the street what does 665 00:35:00,630 --> 00:34:49,570 it mean to him he can be glad he doesn't 666 00:35:04,710 --> 00:35:00,640 live on Jupiter what you mean in terms 667 00:35:06,540 --> 00:35:04,720 of knowledge the well we've never had 668 00:35:08,190 --> 00:35:06,550 the opportunity to know in advance in a 669 00:35:09,690 --> 00:35:08,200 comment or a broken up asteroid or 670 00:35:11,670 --> 00:35:09,700 whatever it is who's going to hit a 671 00:35:13,320 --> 00:35:11,680 planet this is the first time in the 672 00:35:15,870 --> 00:35:13,330 history of humans we've been able to 673 00:35:17,339 --> 00:35:15,880 look at this at study it and we're lucky 674 00:35:20,160 --> 00:35:17,349 now that it's a big ones that we can 675 00:35:21,420 --> 00:35:20,170 really see the effects and we'll be 676 00:35:23,579 --> 00:35:21,430 learning more about how that process 677 00:35:25,530 --> 00:35:23,589 operates and how long how deep these 678 00:35:28,079 --> 00:35:25,540 effects are in the atmosphere of Jupiter 679 00:35:30,300 --> 00:35:28,089 and how long they last this has 680 00:35:32,640 --> 00:35:30,310 relevance to the earth we think more in 681 00:35:34,430 --> 00:35:32,650 terms of the origins of the earth we 682 00:35:36,780 --> 00:35:34,440 believe that the earth was formed by 683 00:35:39,630 --> 00:35:36,790 accretion of material coming in from 684 00:35:41,040 --> 00:35:39,640 space and this gives us an idea that's 685 00:35:42,329 --> 00:35:41,050 been talked about whether this might 686 00:35:45,720 --> 00:35:42,339 have been caused the demise of the 687 00:35:47,400 --> 00:35:45,730 dinosaurs probably proved out but we'll 688 00:35:49,380 --> 00:35:47,410 learn more about the general process and 689 00:35:52,800 --> 00:35:49,390 the history of the earth and maybe the 690 00:35:54,240 --> 00:35:52,810 future so can I just add to that I think 691 00:35:55,829 --> 00:35:54,250 there's a little bit more to it than 692 00:35:57,089 --> 00:35:55,839 just the science and of course we're 693 00:35:59,579 --> 00:35:57,099 interested in the science here because 694 00:36:02,910 --> 00:35:59,589 that's what we do but it's a fascinating 695 00:36:05,130 --> 00:36:02,920 thing I mean there are things whizzing 696 00:36:07,470 --> 00:36:05,140 around the solar system smashing into 697 00:36:09,390 --> 00:36:07,480 other things with huge explosions and 698 00:36:11,520 --> 00:36:09,400 that's just really incredible to think 699 00:36:13,500 --> 00:36:11,530 about I mean you know we don't often 700 00:36:14,880 --> 00:36:13,510 think about the universe out there we 701 00:36:17,040 --> 00:36:14,890 just sort of look at the sky and the 702 00:36:19,230 --> 00:36:17,050 stars are their big deal but if we 703 00:36:21,089 --> 00:36:19,240 really should take a step back and it's 704 00:36:23,670 --> 00:36:21,099 a really dynamic world out there it's a 705 00:36:25,680 --> 00:36:23,680 dynamic universe and this is just a key 706 00:36:30,559 --> 00:36:25,690 example of some of the energetics that 707 00:36:37,710 --> 00:36:34,200 from the estimate of the of the size of 708 00:36:39,690 --> 00:36:37,720 the poon do we have any fix on whether 709 00:36:43,019 --> 00:36:39,700 whether enough material will be 710 00:36:50,190 --> 00:36:43,029 deposited around to create a new ring 711 00:36:51,779 --> 00:36:50,200 around Jupiter well I think that you 712 00:36:53,160 --> 00:36:51,789 know all of that material is just going 713 00:36:54,480 --> 00:36:53,170 to fall right back down the stuff that 714 00:36:57,059 --> 00:36:54,490 might contribute to the ring is a 715 00:36:58,769 --> 00:36:57,069 something mrs. Jupiter basically you 716 00:37:00,809 --> 00:36:58,779 know the dust when you saw around the 717 00:37:02,249 --> 00:37:00,819 comet you know everything that you know 718 00:37:04,289 --> 00:37:02,259 you saw in that plume is coming right 719 00:37:08,910 --> 00:37:04,299 back down eunos gravitationally bound 720 00:37:10,049 --> 00:37:08,920 Jupiter is not going to escape so we do 721 00:37:13,410 --> 00:37:10,059 have you know we had a fair amount of 722 00:37:19,910 --> 00:37:13,420 dust and maybe there will be people 723 00:37:23,759 --> 00:37:22,829 please wait for the mic and is there 724 00:37:25,890 --> 00:37:23,769 anything about any of your 725 00:37:27,539 --> 00:37:25,900 experimentation that might indicate when 726 00:37:29,940 --> 00:37:27,549 this is all over whether there's any 727 00:37:38,779 --> 00:37:29,950 kind of a more solid core in the center 728 00:37:41,460 --> 00:37:38,789 of this otherwise gaseous planet I guess 729 00:37:44,339 --> 00:37:41,470 we already know a lot about Jupiter and 730 00:37:46,229 --> 00:37:44,349 from Voyager flybys and Pioneer 731 00:37:49,979 --> 00:37:46,239 spacecraft flybys we have a pretty good 732 00:37:53,160 --> 00:37:49,989 idea of its interior structure and we 733 00:37:55,979 --> 00:37:53,170 know that there is a probably a solid 734 00:37:58,950 --> 00:37:55,989 core but that is very much much deeper 735 00:38:02,249 --> 00:37:58,960 down then these comments could possibly 736 00:38:04,349 --> 00:38:02,259 penetrate the only thing that well there 737 00:38:07,559 --> 00:38:04,359 is another piece to this the seismic 738 00:38:09,479 --> 00:38:07,569 wave phenomena may end up telling us 739 00:38:12,450 --> 00:38:09,489 something about something different and 740 00:38:15,599 --> 00:38:12,460 that is the boundary between gaseous 741 00:38:17,160 --> 00:38:15,609 hydrogen and a phase of hydrogen that 742 00:38:19,920 --> 00:38:17,170 comes about only under very high 743 00:38:22,019 --> 00:38:19,930 pressures and in Jupiter we believe that 744 00:38:24,839 --> 00:38:22,029 this occurs although it's not exactly 745 00:38:25,979 --> 00:38:24,849 clear where that transition occurs so 746 00:38:28,570 --> 00:38:25,989 there's some hope that will learn about 747 00:38:30,430 --> 00:38:28,580 that just quick follow-up is it 748 00:38:32,710 --> 00:38:30,440 that any of these pieces could penetrate 749 00:38:35,110 --> 00:38:32,720 deeply enough into wherever this hard 750 00:38:37,150 --> 00:38:35,120 matter is that part of the dark stuff 751 00:38:45,520 --> 00:38:37,160 actually could be substance from the 752 00:38:51,200 --> 00:38:45,530 hard interior of Jupiter no any further 753 00:38:56,390 --> 00:38:53,870 Oh what do you expect from the larger X 754 00:39:01,640 --> 00:38:56,400 from the larger impacts down the line 755 00:39:04,790 --> 00:39:01,650 with the what you know now more slots 756 00:39:06,200 --> 00:39:04,800 yeah this is this is just a preview it 757 00:39:08,359 --> 00:39:06,210 looks like it's gonna be an even bigger 758 00:39:10,760 --> 00:39:08,369 show for the rest of the week the only 759 00:39:13,880 --> 00:39:10,770 thing special about this one was that it 760 00:39:15,829 --> 00:39:13,890 was the first one we've got some 20-odd 761 00:39:19,010 --> 00:39:15,839 more to go including some much brighter 762 00:39:26,290 --> 00:39:19,020 ones so you would expect the bigger ones 763 00:39:28,460 --> 00:39:26,300 to penetrate farther perhaps sure okay 764 00:39:30,380 --> 00:39:28,470 next over here up please name and 765 00:39:32,210 --> 00:39:30,390 affiliation please Chris leads from NHK 766 00:39:33,920 --> 00:39:32,220 is there anything you can tell about 767 00:39:37,940 --> 00:39:33,930 what kinds of chemical reactions were 768 00:39:40,400 --> 00:39:37,950 taking place during the impact not not 769 00:39:42,920 --> 00:39:40,410 what can I should I start not from this 770 00:39:45,079 --> 00:39:42,930 this is just strictly imaging but now 771 00:39:46,760 --> 00:39:45,089 I'll pass it over to keep yeah that's 772 00:39:49,130 --> 00:39:46,770 what we hope to learn about later in the 773 00:39:50,780 --> 00:39:49,140 week when we get the spectroscopic data 774 00:39:56,420 --> 00:39:50,790 back that will tell us about the 775 00:39:58,700 --> 00:39:56,430 composition of the atmosphere ok if 776 00:40:01,520 --> 00:39:58,710 there are no further questions I think 777 00:40:04,400 --> 00:40:01,530 we will go ahead and wrap it up and we 778 00:40:07,490 --> 00:40:04,410 will what we like to do before we close 779 00:40:09,349 --> 00:40:07,500 and lose the satellite is have another 780 00:40:11,780 --> 00:40:09,359 replay of the still image and we'll run 781 00:40:13,790 --> 00:40:11,790 both the videos and for the benefit of 782 00:40:16,579 --> 00:40:13,800 those here we'll we'll have that on the 783 00:40:18,440 --> 00:40:16,589 monitor also I want to remind everyone 784 00:40:21,130 --> 00:40:18,450 that tomorrow morning sunday morning at 785 00:40:24,710 --> 00:40:21,140 ten a.m. eastern time we will have 786 00:40:26,960 --> 00:40:24,720 briefing which will have more images 787 00:40:28,910 --> 00:40:26,970 also some information from other 788 00:40:32,030 --> 00:40:28,920 observatories in the nasa and NSF 789 00:40:35,329 --> 00:40:32,040 observing campaign and at that panel 790 00:40:37,220 --> 00:40:35,339 will have doctors shoemaker and I 791 00:40:40,790 --> 00:40:37,230 Carolyn shoemaker and Dave levy and 792 00:40:42,170 --> 00:40:40,800 member the hubble science team and hope 793 00:40:44,870 --> 00:40:42,180 to see you out there and that will be 794 00:40:47,510 --> 00:40:44,880 also live on NASA select with Q&A from 795 00:40:50,000 --> 00:40:47,520 the Centers at that point we'll go ahead 796 00:40:52,160 --> 00:40:50,010 and close the press conference thank you 797 00:41:00,530 --> 00:40:52,170 for coming and we'll see you tomorrow 798 00:41:00,540 --> 00:42:34,050 these bro 799 00:42:34,060 --> 00:42:43,000 Oh 800 00:42:47,720 --> 00:42:46,250 so it's another step in the water with 801 00:42:52,220 --> 00:42:47,730 movie night we're looking for something 802 00:42:53,780 --> 00:42:52,230 much this is the first time yeah this is 803 00:42:56,510 --> 00:42:53,790 the latitude that we're looking for 804 00:43:01,160 --> 00:42:56,520 something like their contours to tell me
