00:03:00,570 year of hubble hubble and across the 76 00:03:05,630 --> 00:03:03,840 universe and i will be my story for 77 00:03:08,210 --> 00:03:05,640 today and i apologize there isn't more 78 00:03:10,760 --> 00:03:08,220 than one story j but we got lots of cool 79 00:03:13,850 --> 00:03:10,770 stuff here about this great revisiting a 80 00:03:16,580 --> 00:03:13,860 legend ok we have certain legendary 81 00:03:18,860 --> 00:03:16,590 images we think of Hubble there are 82 00:03:21,950 --> 00:03:18,870 certain images that you say wow that's 83 00:03:24,260 --> 00:03:21,960 something that just is so cool that will 84 00:03:26,810 --> 00:03:24,270 live forever in your memory of Hubble I 85 00:03:29,470 --> 00:03:26,820 think perhaps the most famous image 86 00:03:31,900 --> 00:03:29,480 shuttle has ever released is this one 87 00:03:34,160 --> 00:03:31,910 the pillars in the Eagle Nebula 88 00:03:38,270 --> 00:03:34,170 poetically named the pillars of creation 89 00:03:41,990 --> 00:03:38,280 and the first come out this one was 90 00:03:44,000 --> 00:03:42,000 first released in November 1995 okay 91 00:03:46,790 --> 00:03:44,010 that is I fact definitely an iconic 92 00:03:50,030 --> 00:03:46,800 picture yeah and matter of fact you know 93 00:03:52,100 --> 00:03:50,040 November 1995 was an amazing month for 94 00:03:54,050 --> 00:03:52,110 us because not only did we release this 95 00:03:56,210 --> 00:03:54,060 image but we also released that 96 00:03:59,449 --> 00:03:56,220 beautiful image of the trapezium cluster 97 00:04:02,120 --> 00:03:59,459 in the Orion Nebula that first of Bob 98 00:04:03,770 --> 00:04:02,130 odell image of the Orion Nebula getting 99 00:04:05,660 --> 00:04:03,780 into the trapezium it was like five 100 00:04:08,600 --> 00:04:05,670 thousand pixels across up by five 101 00:04:10,130 --> 00:04:08,610 dollars because amazing so that all came 102 00:04:13,970 --> 00:04:10,140 out within one month so that was a good 103 00:04:16,880 --> 00:04:13,980 month for us but this one this one is 104 00:04:19,580 --> 00:04:16,890 one that people always remember and it's 105 00:04:22,340 --> 00:04:19,590 nicknamed the pillars of creation simply 106 00:04:25,550 --> 00:04:22,350 because these are places where stars are 107 00:04:27,650 --> 00:04:25,560 forming all right so you have the these 108 00:04:29,960 --> 00:04:27,660 long tall pillars 109 00:04:31,880 --> 00:04:29,970 they're being blown back by gas from hot 110 00:04:34,940 --> 00:04:31,890 stars they're forming in this cluster 111 00:04:36,110 --> 00:04:34,950 and in the very tops of these pillars 112 00:04:38,360 --> 00:04:36,120 and I'll show you some of the details 113 00:04:40,430 --> 00:04:38,370 admit our places where stars are 114 00:04:42,230 --> 00:04:40,440 actually forming and so hence that's 115 00:04:44,930 --> 00:04:42,240 where the nickname colors of creation 116 00:04:46,880 --> 00:04:44,940 comes from but let's give you a let's 117 00:04:48,410 --> 00:04:46,890 back up a little bit let's actually give 118 00:04:49,880 --> 00:04:48,420 you a little more context for this 119 00:04:54,230 --> 00:04:49,890 little green explore this in great 120 00:04:56,920 --> 00:04:54,240 detail well this is an image of the 121 00:05:01,280 --> 00:04:56,930 Milky Way center of the Milky Way galaxy 122 00:05:03,170 --> 00:05:01,290 from a cure for GE here is wonderful and 123 00:05:07,460 --> 00:05:03,180 lets us use a lot of his images here at 124 00:05:09,490 --> 00:05:07,470 hubbell and what has been drawn out here 125 00:05:12,610 --> 00:05:09,500 is the locations a lot of different 126 00:05:18,110 --> 00:05:12,620 messy objects near the galactic center 127 00:05:20,960 --> 00:05:18,120 you can see em 16 m 18 and 25 and 23 and 128 00:05:23,390 --> 00:05:20,970 28 cetera but the one that's been boxed 129 00:05:26,780 --> 00:05:23,400 in there is m16 and that is the Eagle 130 00:05:28,070 --> 00:05:26,790 Nebula now some of you may not know when 131 00:05:29,600 --> 00:05:28,080 you're looking towards the galactic 132 00:05:33,230 --> 00:05:29,610 center you're not going to have this 133 00:05:35,090 --> 00:05:33,240 good seeing just to show some of you the 134 00:05:37,340 --> 00:05:35,100 constellation Sagittarius is drawn in 135 00:05:40,190 --> 00:05:37,350 the lower right and I'm going to put in 136 00:05:42,560 --> 00:05:40,200 the constellation lines for for you the 137 00:05:44,780 --> 00:05:42,570 constellation alarms yes that teapot 138 00:05:47,510 --> 00:05:44,790 this isn't the entire constellation 139 00:05:48,890 --> 00:05:47,520 Sagittarius but it's the only part of 140 00:05:52,100 --> 00:05:48,900 the constellation stare said shares that 141 00:05:53,960 --> 00:05:52,110 I know okay that's a point everybody 142 00:05:56,360 --> 00:05:53,970 recognizes that's what I all learned on 143 00:05:58,159 --> 00:05:56,370 as well as how to find a teapot exactly 144 00:06:00,200 --> 00:05:58,169 you gotta find the teapot and then 145 00:06:03,020 --> 00:06:00,210 you're actually looking towards the 146 00:06:05,659 --> 00:06:03,030 center of the Milky Way for those of us 147 00:06:06,860 --> 00:06:05,669 in the northern hemisphere you're only 148 00:06:09,770 --> 00:06:06,870 going to be able to see this in the 149 00:06:12,020 --> 00:06:09,780 summertime July and August and it's 150 00:06:14,659 --> 00:06:12,030 going to be low on the horizon and so 151 00:06:16,820 --> 00:06:14,669 the the center of the galaxy is not 152 00:06:18,380 --> 00:06:16,830 going to be visible in winter it's only 153 00:06:20,630 --> 00:06:18,390 visible in summertime and it only gets 154 00:06:22,730 --> 00:06:20,640 you know tens of trees 30 degrees or so 155 00:06:25,340 --> 00:06:22,740 40 degrees above the above the horizon 156 00:06:29,240 --> 00:06:25,350 and summertime and that's when you can 157 00:06:32,480 --> 00:06:29,250 see the teapot okay and for those of you 158 00:06:34,280 --> 00:06:32,490 who think of astrology and think of that 159 00:06:36,980 --> 00:06:34,290 you are such you're born under the sign 160 00:06:39,650 --> 00:06:36,990

called clear starry nights calm I 172 00:07:16,910 --> 00:07:13,680 couldn't find the name of the person who 173 00:07:18,980 --> 00:07:16,920 does these images he didn't put a lot of 174 00:07:20,450 --> 00:07:18,990 these which I puts their put their their 175 00:07:23,420 --> 00:07:20,460 names and credits all over the place 176 00:07:25,820 --> 00:07:23,430 with this shows you perhaps why it's 177 00:07:27,830 --> 00:07:25,830 called the Eagle Nebula I wanted a wider 178 00:07:32,240 --> 00:07:27,840 base view so you can see sort of a wing 179 00:07:35,090 --> 00:07:32,250 extending to the lower left and the the 180 00:07:36,980 --> 00:07:35,100 head up at the top of the top left and 181 00:07:38,360 --> 00:07:36,990 the spread of the wings of the evil 182 00:07:39,950 --> 00:07:38,370 sitting in front of you right you can 183 00:07:41,750 --> 00:07:39,960 sort of do you see that Tony yeah yeah 184 00:07:43,220 --> 00:07:41,760 can you do you have the ability to use 185 00:07:45,620 --> 00:07:43,230 your cursor at all to kind of circle 186 00:07:48,350 --> 00:07:45,630 what you're talking about or i do but 187 00:07:50,060 --> 00:07:48,360 it's that this screen is such high 188 00:07:51,680 --> 00:07:50,070 resolution all the ice I don't see it 189 00:07:53,360 --> 00:07:51,690 though go ahead and say ok alright 190 00:07:55,790 --> 00:07:53,370 settlement will you bring

the wing all right ok and then 194 00:08:05,240 --> 00:08:03,570 then back up to the other wing the other 195 00:08:08,000 --> 00:08:05,250 wing is not so sharp maybe he's got the 196 00:08:10,940 --> 00:08:08,010 the other wing folded in right ok so 197 00:08:13,100 --> 00:08:10,950 this is a needle I see the eagle this is 198 00:08:14,930 --> 00:08:13,110 a is it a red wavelengths image do you 199 00:08:18,140 --> 00:08:14,940 know what would fill out this wilderness 200 00:08:20,630 --> 00:08:18,150 well most of the nebula in the universe 201 00:08:23,420 --> 00:08:20,640 glow in the light of hydrogen alpha 202 00:08:26,420 --> 00:08:23,430 right because most of the the gas in the 203 00:08:28,460 --> 00:08:26,430 universe is hydrogen and the excitation 204 00:08:29,780 --> 00:08:28,470 line of hydrogen that gets excited is is 205 00:08:32,330 --> 00:08:29,790 hydrogen alpha which is a red 206 00:08:35,060 --> 00:08:32,340 wavelengths right 65-62 angstroms I 207 00:08:37,850 --> 00:08:35,070 believe there you go so the point is is 208 00:08:39,260 --> 00:08:37,860 that most nebula appear red which is one 209 00:08:41,300 --> 00:08:39,270 of reasons why I went out to search for 210 00:08:42,830 --> 00:08:41,310 this image want to show you the eagle 211 00:08:45,080 --> 00:08:42,840 but to to show you what it really looks 212 00:08:47,300 --> 00:08:45,090 like it isn't the green of the Hubble 213 00:08:49,420 --> 00:08:47,310 image right the Greeners the Hubble 214 00:08:54,170 --> 00:08:49,430 image is actually the oxygen line 215 00:08:55,100 --> 00:08:54,180 colored green uh with in so that it's 216 00:08:57,019 --> 00:08:55,110 not 217 00:08:58,490 --> 00:08:57,029 hubble images use very specific filters 218 00:09:00,560 --> 00:08:58,500 and doesn't show you what the human eye 219 00:09:02,500 --> 00:09:00,570 would see this is a closer approximation 220 00:09:05,630 --> 00:09:02,510 to what the human eye might see okay 221 00:09:07,250 --> 00:09:05,640 okay so where are those Hubble images 222 00:09:10,400 --> 00:09:07,260 well you look in the center of at the 223 00:09:11,990 --> 00:09:10,410 heart of the eagle and you can see these 224 00:09:14,870 --> 00:09:12,000 the pillars and they're kind of fuzzy 225 00:09:16,910 --> 00:09:14,880 here I'm going to switch to oops where 226 00:09:19,579 --> 00:09:16,920 am I I'm hitting the wrong I got two 227 00:09:21,380 --> 00:09:19,589 three laptops laptop and a desktop in 228 00:09:25,550 --> 00:09:21,390 front of me I keep hitting the wrong 229 00:09:28,009 --> 00:09:25,560 keyboard so here this is a zoomed in 230 00:09:30,829 --> 00:09:28,019 toward the center and you can see 231 00:09:34,519 --> 00:09:30,839 outlined in yellow the three pillars 232 00:09:37,519 --> 00:09:34,529 from the 1995 Hubble image taken with 233 00:09:40,220 --> 00:09:37,529 with pick two so it has that interesting 234 00:09:42,920 --> 00:09:40,230 Chevron shape to it yeah wide field 235 00:09:47,569 --> 00:09:42,930 planetary camera 2 there you go with 236 00:09:50,000 --> 00:09:47,579 thick too near well in 2005 we had a new 237 00:09:53,480 --> 00:09:50,010 camera on Hubble the advanced camera for 238 00:09:56,480 --> 00:09:53,490 surveys and we took a two pointing image 239 00:09:58,460 --> 00:09:56,490 of another pillar what we call the spire 240 00:10:01,610 --> 00:09:58,470 in the eagle nebula you can see that 241 00:10:05,780 --> 00:10:01,620 also outlined here so for Hubble's 15th 242 00:10:09,079 --> 00:10:05,790 anniversary we did this image of the 243 00:10:12,889 --> 00:10:09,089 spire in the eagle nebula and you can 244 00:10:14,780 --> 00:10:12,899 see actually is very inspiring it's nice 245 00:10:16,250 --> 00:10:14,790 here but to give it more resolution on 246 00:10:18,980 --> 00:10:16,260 the small screen I'm going to turn it 247 00:10:20,540 --> 00:10:18,990 sideways so you can actually see some a 248 00:10:22,370 --> 00:10:20,550 little bit more our viewers can see a 249 00:10:25,550 --> 00:10:22,380 little bit more of the detail okay ah 250 00:10:28,699 --> 00:10:25,560 and what I like about this is that you 251 00:10:30,290 --> 00:10:28,709 see all of us stuff all of the material 252 00:10:33,259 --> 00:10:30,300 up here that's flowing off of the pillar 253 00:10:36,769 --> 00:10:33,269 you've got the bright head to the pillar 254 00:10:38,960 --> 00:10:36,779 okay where the ionizing radiation is 255 00:10:40,850 --> 00:10:38,970 smashing into this dark gasp the 256 00:10:43,939 --> 00:10:40,860 high-energy radiation is taking that 257 00:10:45,980 --> 00:10:43,949 dark molecular gas heating it ionizing 258 00:10:48,110 --> 00:10:45,990 it turning it into ionized gas that's 259 00:10:52,130 --> 00:10:48,120 flowing off the top you've also got this 260 00:10:54,590 --> 00:10:52,140 jet coming up the top here okay which is 261 00:10:58,430 --> 00:10:54,600 probably from actually I don't think 262 00:11:00,680 --> 00:10:58,440 that's a bet that that's the no I think 263 00:11:02,240 --> 00:11:00,690 that back that's not a jet I'm sorry I'm 264 00:11:05,449 --> 00:11:02,250 used to seeing jet jets it's a little 265 00:11:06,680 --> 00:11:05,459 small smaller I want to go to the right 266 00:11:09,030 --> 00:11:06,690 of the image right now just in case 267 00:11:10,740 --> 00:11:09,040 people on the right of this image so 268 00:11:13,050 --> 00:11:10,750 you've got this really bright region up 269 00:11:16,230 --> 00:11:13,060 here and you've got this really long 270 00:11:18,769 --> 00:11:16,240 tail of material hanging in behind it on 271 00:11:21,420 --> 00:11:18,779 and it's not very beautiful and poetic 272 00:11:28,499 --> 00:11:21,430 image and that's what we released for 273 00:11:31,170 --> 00:11:28,509 our 20 15th anniversary okay so if so if 274 00:11:34,980 --> 00:11:31,180 we go back to our 1995 invention we put 275 00:11:37,699 --> 00:11:34,990 it up here we visited this using our 276 00:11:40,860 --> 00:11:37,709 brand new camera wide field camera 3 277 00:11:42,360 --> 00:11:40,870 right so first first image I showed you 278 00:11:44,430 --> 00:11:42,370 is with pick two with one image i'm 279 00:11:46,139 --> 00:11:44,440 showing you now the second one was a CS 280 00:11:49,230 --> 00:11:46,149 and so we've gone back to the Eagle 281 00:11:52,139 --> 00:11:49,240 Olivia wide field camera 3 and we've 282 00:11:54,569 --> 00:11:52,149 done a mosaic of four pointings across 283 00:12:00,059 --> 00:11:54,579 it and so at the exact same scale as the 284 00:12:01,889 --> 00:12:00,069 1995 image here is our 2015 image of the 285 00:12:03,120 --> 00:12:01,899 e pillars in the Eagle Nebula I never 286 00:12:05,730 --> 00:12:03,130 get tired of seeing that it's really 287 00:12:07,680 --> 00:12:05,740 nice that's amazing you know you but 288 00:12:10,800 --> 00:12:07,690 I've been staring at this all month oh I 289 00:12:14,490 --> 00:12:10,810 know yeah and it still doesn't lose its 290 00:12:16,559 --> 00:12:14,500 beauty to it it's just amazing just how 291 00:12:18,449 --> 00:12:16,569 much there is here so go back to the 292 00:12:20,309 --> 00:12:18,459 2005 and then just kind of go back are 293 00:12:22,379 --> 00:12:20,319 you are you gonna actually how about if 294 00:12:25,110 --> 00:12:22,389 I go to the next day there you go that's 295 00:12:27,150 --> 00:12:25,120 where I do an overland okay I should 296 00:12:29,250 --> 00:12:27,160 have done had it so to prep for this 297 00:12:30,689 --> 00:12:29,260 this presentation I actually went 298 00:12:33,569 --> 00:12:30,699 through and got the highest resolution 299 00:12:34,980 --> 00:12:33,579 images and i overlaid them and and work 300 00:12:38,490 --> 00:12:34,990 them because i'm going to show you all 301 00:12:40,230 --> 00:12:38,500 sorts of details about this and show 302 00:12:42,660 --> 00:12:40,240 them how they look in one image and how 303 00:12:44,100 --> 00:12:42,670 they look in the other image so you're 304 00:12:47,670 --> 00:12:44,110 the green in the width pick two of gaga 305 00:12:50,129 --> 00:12:47,680 image you said was due to oxygen right 306 00:12:53,280 --> 00:12:50,139 okay so the reason why these aren't red 307 00:12:59,890 --> 00:12:53,290 is they aren't red green blue filters 308 00:13:06,340 --> 00:13:03,580 hello line okay so that there are three 309 00:13:09,490 --> 00:13:06,350 specific filters designed to get the 310 00:13:12,970 --> 00:13:09,500 emission from three specific elements 311 00:13:15,190 --> 00:13:12,980 and different elements will be excited 312 00:13:17,620 --> 00:13:15,200 at different temperatures so in a way 313 00:13:19,870 --> 00:13:17,630 you're here each of the the filters 314 00:13:24,430 --> 00:13:19,880 probes a different temperature structure 315 00:13:28,630 --> 00:13:24,440 within the nebula and so the color is 316 00:13:32,530 --> 00:13:28,640 chosen in 1995 put the oxygen in green 317 00:13:35,830 --> 00:13:32,540 the colors chosen in 2015 put the oxygen 318 00:13:37,660 --> 00:13:35,840 in blue so that's why the colors the 319 00:13:41,640 --> 00:13:37,670 color palette chosen here was different 320 00:13:44,200 --> 00:13:41,650 okay just to keep things clear huh 321 00:13:46,900 --> 00:13:44,210 good-o artistic I mean we were very 322 00:13:49,660 --> 00:13:46,910 inexperienced at creating these gorgeous 323 00:13:52,210 --> 00:13:49,670 Hubble images back in 1995 we've got 324 00:13:55,090 --> 00:13:52,220 another what is it another 20 years of 325 00:13:57,970 --> 00:13:55,100 experience in doing this and the 326 00:14:01,450 --> 00:13:57,980 artistic choice of the colors this time 327 00:14:03,120 --> 00:14:01,460 came out like this very quiet so let's 328 00:14:09,280 --> 00:14:03,130 compare a first thing what you see is 329 00:14:11,920 --> 00:14:09,290 that the the with pick to the whiskey 3 330 00:14:14,860 --> 00:14:11,930 image the new 2015 image covers a lot 331 00:14:16,900 --> 00:14:14,870 more area shows you a lot larger field 332 00:14:20,350 --> 00:14:16,910 of view more pixels whereas the original 333 00:14:24,010 --> 00:14:20,360 image was 2.6 million pixels our new 334 00:14:27,610 --> 00:14:24,020 image is 60 million pixels so we've got 335 00:14:30,040 --> 00:14:27,620 30 times the number of pixels to look at 336 00:14:32,680 --> 00:14:30,050 the resolution is actually about a 337 00:14:34,540 --> 00:14:32,690 factor of 2 better across the entire 338 00:14:36,190 --> 00:14:34,550 image but there's so much more in the 339 00:14:40,360 --> 00:14:36,200 image and let's explore a little bit of 340 00:14:43,690 --> 00:14:40,370 that ok ok so if we zoom in to the 341 00:14:48,160 --> 00:14:43,700 center of the leftmost pillar on the 342 00:14:51,850 --> 00:14:48,170 left you see the with picked the 1995 343 00:14:55,440 --> 00:14:51,860 image and on the right you see the 2015 344 00:14:57,520 --> 00:14:55,450 image and there are twice as the 345 00:15:00,430 --> 00:14:57,530 resolution is a factor of two in each 346 00:15:03,490 --> 00:15:00,440 direction so correspondingly there is a 347 00:15:06,850 --> 00:15:03,500 factor of four times more pixels per 348 00:15:10,780 --> 00:15:06,860 unit area in what you're seeing so you 349 00:15:13,810 --> 00:15:10,790 can see that the for example if you take 350 00:15:16,360 --> 00:15:13,820 a look at the ridge along he 351 00:15:19,090 --> 00:15:16,370 okay see that Ridge along here this this 352 00:15:20,710 --> 00:15:19,100 ionization argue on the right image or 353 00:15:22,810 --> 00:15:20,720 pointer yes I'm pointing on the writing 354 00:15:25,930 --> 00:15:22,820 yeah if you look at that's this the same 355 00:15:29,020 --> 00:15:25,940 Ridge on the left image you can see how 356 00:15:31,270 --> 00:15:29,030 it's just fuzzed-out yeah right you see 357 00:15:35,170 --> 00:15:31,280 a lot more structure if you look at this 358 00:15:38,230 --> 00:15:35,180 I don't know smoke stack this very long 359 00:15:40,390 --> 00:15:38,240 dark black a black tube and at the top 360 00:15:42,670 --> 00:15:40,400 of that in the detail that you can see 361 00:15:46,360 --> 00:15:42,680 there you can see just a bit more detail 362 00:15:48,880 --> 00:15:46,370 in the 2015 image and then at the very 363 00:15:51,310 --> 00:15:48,890 highest peak that point that tiny little 364 00:15:53,620 --> 00:15:51,320 nib on there you can start to see the 365 00:15:55,930 --> 00:15:53,630 structure is that as a sign to them 366 00:15:57,970 --> 00:15:55,940 scientific term yes these are technical 367 00:16:01,210 --> 00:15:57,980 terms the other prizes supplement that's 368 00:16:02,740 --> 00:16:01,220 what the nib you can start to see that 369 00:16:04,360 --> 00:16:02,750 structure and so this is to show you 370 00:16:07,420 --> 00:16:04,370 that you know we aren't getting ten 371 00:16:10,000 --> 00:16:07,430 times at a resolution but we are getting 372 00:16:12,220 --> 00:16:10,010 a factor of two resolution and one of 373 00:16:15,670 --> 00:16:12,230 the science results that they came up 374 00:16:17,980 --> 00:16:15,680 with was that you know in 1995 they 375 00:16:20,610 --> 00:16:17,990 tried to measure the thickness of these 376 00:16:23,260 --> 00:16:20,620 yellow that yellow edge to the dark ass 377 00:16:24,730 --> 00:16:23,270 it's called the ionization front the 378 00:16:27,450 --> 00:16:24,740 thickness to the ionization front they 379 00:16:30,610 --> 00:16:27,460 determined was below Hubble's resolution 380 00:16:32,440 --> 00:16:30,620 well they did it again in 2015 and you 381 00:16:36,840 --> 00:16:32,450 look at that and you know what it's 382 00:16:40,780 --> 00:16:36,850 still below Hubble's resolution Wow the 383 00:16:43,900 --> 00:16:40,790 crossover from this hot ionized gas to 384 00:16:47,680 --> 00:16:43,910 this thick dense molecular gas is really 385 00:16:49,960 --> 00:16:47,690 really thin it's it's you know hundreds 386 00:16:52,090 --> 00:16:49,970 of parsecs it's less than hundreds of 387 00:16:54,490 --> 00:16:52,100 parsecs at the distance of Eagle Nebula 388 00:16:57,300 --> 00:16:54,500 showing you that you know that the 389 00:17:00,610 --> 00:16:57,310 transition region is really really sharp 390 00:17:02,980 --> 00:17:00,620 something that we had I guess you sort 391 00:17:04,780 --> 00:17:02,990 of learn that in graduate school that is 392 00:17:07,179 --> 00:17:04,790 supposed to be a very thick very very 393 00:17:09,510 --> 00:17:07,189 sharp transition but to see it in this 394 00:17:12,670 --> 00:17:09,520 amazing detail it's really kind of cool 395 00:17:14,560 --> 00:17:12,680 so while you're on this topic let me get 396 00:17:17,170 --> 00:17:14,570 Nicholas's question in here Nicholas 397 00:17:20,770 --> 00:17:17,180 greater from the Q&A app the red line on 398 00:17:23,470 --> 00:17:20,780 the end the old image yes cosmic ray 399 00:17:27,730 --> 00:17:23,480 hitting the red line on the old image is 400 00:17:30,160 --> 00:17:27,740 actually a diffraction spike from a star 401 00:17:32,320 --> 00:17:30,170 our that's off-screen above if you look 402 00:17:34,810 --> 00:17:32,330 in the the new image you can see a 403 00:17:36,880 --> 00:17:34,820 diagonal line in the upper left off yep 404 00:17:40,600 --> 00:17:36,890 yeah that's the diffraction fight bike 405 00:17:43,030 --> 00:17:40,610 from the same bright star yeah so I look 406 00:17:45,340 --> 00:17:43,040 so it looks so regular though in the the 407 00:17:47,919 --> 00:17:45,350 older image it's like it's just like a 408 00:17:49,210 --> 00:17:47,929 straight line that's weird yeah okay 409 00:17:51,460 --> 00:17:49,220 yeah so that's what that is Nicholas 410 00:17:54,490 --> 00:17:51,470 okay go ahead so now we're going to move 411 00:17:59,110 --> 00:17:54,500 to the top of a set of the middle pillar 412 00:18:01,870 --> 00:17:59,120 okay and this is where the in the white 413 00:18:04,870 --> 00:18:01,880 coat planetary camera 2 we had the pc 414 00:18:06,790 --> 00:18:04,880 chip the planetary camera chip the 415 00:18:08,919 --> 00:18:06,800 reason with pic to have that you know 416 00:18:12,220 --> 00:18:08,929 chevron shape is you've got three chips 417 00:18:14,410 --> 00:18:12,230 that are the same and then you've got 418 00:18:17,230 --> 00:18:14,420 one ship that's twice the resolution so 419 00:18:19,030 --> 00:18:17,240 this would be the chip this will be the 420 00:18:21,610 --> 00:18:19,040 spot in the Eagle Nebula where you'd 421 00:18:23,530 --> 00:18:21,620 have higher resolution in the nineteen 422 00:18:25,900 --> 00:18:23,540 ninety-five image just this one small 423 00:18:27,580 --> 00:18:25,910 region in the nineteen ninety five min 424 00:18:28,960 --> 00:18:27,590 which has high resolution and so I 425 00:18:31,450 --> 00:18:28,970 wanted to show you this to show you that 426 00:18:34,360 --> 00:18:31,460 the resolution from the 1995 image is 427 00:18:37,960 --> 00:18:34,370 roughly comparable to the resolution in 428 00:18:40,450 --> 00:18:37,970 the 2015 image in this one region now 429 00:18:42,820 --> 00:18:40,460 it's still not as good it's here in the 430 00:18:46,299 --> 00:18:42,830 older camera it looks more anyway it's 431 00:18:50,530 --> 00:18:46,309 definitely noisier the improvement in 432 00:18:52,210 --> 00:18:50,540 the in the detectors it is apparent but 433 00:18:54,880 --> 00:18:52,220 the improvement in resolution is not 434 00:18:58,870 --> 00:18:54,890 quite as a parrot in this region as it 435 00:19:01,480 --> 00:18:58,880 was in the other regions just a one 436 00:19:03,310 --> 00:19:01,490 little thing that I like to I like to 437 00:19:05,830 --> 00:19:03,320 point out is d I'm looking at the right 438 00:19:09,299 --> 00:19:05,840 hand image ya see that little thing 439 00:19:13,450 --> 00:19:09,309 their looks like a jellyfish a jellyfish 440 00:19:16,090 --> 00:19:13,460 I think all these small little details 441 00:19:18,430 --> 00:19:16,100 start to pop out when you look at that 442 00:19:20,919 --> 00:19:18,440 this new image of just all these small 443 00:19:22,780 --> 00:19:20,929 was more than that to you could see all 444 00:19:24,640 --> 00:19:22,790 the structure and the clouds to I mean 445 00:19:26,560 --> 00:19:24,650 like there's that that big central 446 00:19:29,500 --> 00:19:26,570 feature there is just all of it looks so 447 00:19:31,870 --> 00:19:29,510 much more defined in the newer image 448 00:19:34,480 --> 00:19:31,880 right so let's go to their really the 449 00:19:37,060 --> 00:19:34,490 real highlight proportion of them the 450 00:19:40,120 --> 00:19:37,070 top of the leftmost pillar okay yeah 451 00:19:41,539 --> 00:19:40,130 this is where you can see the 1995 image 452 00:19:43,729 --> 00:19:41,549 to the 2050 453 00:19:46,609 --> 00:19:43,739 which we get a significant resolution 454 00:19:50,149 --> 00:19:46,619 all sorts of cool things going on in 455 00:19:52,729 --> 00:19:50,159 here the structure in detail and as you 456 00:19:56,779 --> 00:19:52,739 said the structure of the gas is really 457 00:20:00,109 --> 00:19:56,789 apparent here just the when the ionizing 458 00:20:02,930 --> 00:20:00,119 radiation hits this cold dense gas that 459 00:20:04,970 --> 00:20:02,940 gas ionizes and then sort of evaporates 460 00:20:08,359 --> 00:20:04,980 up you should talk about what ionizing 461 00:20:10,279 --> 00:20:08,369 is they don't think ok yeah ok yeah I 462 00:20:14,599 --> 00:20:10,289 would you tend to try that around with 463 00:20:18,889 --> 00:20:14,609 abandon so ionization is when an high 464 00:20:21,619 --> 00:20:18,899 energy photon hits a atom and liberate 465 00:20:23,960 --> 00:20:21,629 some electron ok it puts energy into the 466 00:20:28,489 --> 00:20:23,970 atom and the electron goes free from the 467 00:20:32,930 --> 00:20:28,499 nucleus and so one or more electrons can 468 00:20:35,479 --> 00:20:32,940 be can be liberated and then your 469 00:20:39,950 --> 00:20:35,489 molecules or your atoms become ionized 470 00:20:41,269 --> 00:20:39,960 gas ok and you when you think of it we 471 00:20:43,519 --> 00:20:41,279 can sort of think of the ionized gas 472 00:20:46,099 --> 00:20:43,529 being set free from this dense molecular 473 00:20:48,109 --> 00:20:46,109 State a little bit like it's a little 474 00:20:51,859 --> 00:20:48,119 bit like the steam you see coming off 475 00:20:55,039 --> 00:20:51,869 water all right going from you know this 476 00:20:57,169 --> 00:20:55,049 dense state to this gaseous state and 477 00:20:59,479 --> 00:20:57,179 you you think of it as flows and you 478 00:21:02,930 --> 00:20:59,489 really can see you can feel the flows of 479 00:21:07,099 --> 00:21:02,940 that material the ionized gas coming off 480 00:21:12,799 --> 00:21:07,109 of this dead stuff now if you look down 481 00:21:15,590 --> 00:21:12,809 in the bottom ok you can see this jet 482 00:21:18,080 --> 00:21:15,600 down here alright I'm going to zoom in 483 00:21:22,039 --> 00:21:18,090 on the jet at the bottom and show it to 484 00:21:24,499 --> 00:21:22,049 you 1995 on the left again 2051 right 485 00:21:26,289 --> 00:21:24,509 and here's where you can truly see the 486 00:21:30,889 --> 00:21:26,299 resolution difference right and right 487 00:21:35,779 --> 00:21:30,899 now this is this one is a jet so this is 488 00:21:40,430 --> 00:21:35,789 a jet from a newborn star inside this 489 00:21:43,849 --> 00:21:40,440 nodule here just above center a new star 490 00:21:46,190 --> 00:21:43,859 has formed all right and so a brand new 491 00:21:48,109 --> 00:21:46,200 star is formed and when stars formed 492 00:21:50,090 --> 00:21:48,119 you've got all this material swirling 493 00:21:52,190 --> 00:21:50,100 around and crashing on to this new 494 00:21:54,440 --> 00:21:52,200 forming star some of the material 495 00:21:55,460 --> 00:21:54,450 actually gets thrown off into these 496 00:21:58,279 --> 00:21:55,470 bipolar 497 00:22:00,770 --> 00:21:58,289 it's material streaming off in opposite 498 00:22:03,890 --> 00:22:00,780 directions and so you can see the jet 499 00:22:07,120 --> 00:22:03,900 extending up and the jet is standing 500 00:22:09,649 --> 00:22:07,130 down spewing away from this newborn star 501 00:22:11,810 --> 00:22:09,659 so there's a star hidden in there and in 502 00:22:13,370 --> 00:22:11,820 fact there's their star birth going on 503 00:22:16,250 --> 00:22:13,380 throughout this whole region as you've 504 00:22:18,980 --> 00:22:16,260 already pointed out but are there any 505 00:22:20,360 --> 00:22:18,990 the if you look at this more diffuse 506 00:22:21,919 --> 00:22:20,370 clouds in there I don't know if you want 507 00:22:23,690 --> 00:22:21,929 to go back to that one right before that 508 00:22:26,630 --> 00:22:23,700 you were just showing but there's lots 509 00:22:28,669 --> 00:22:26,640 of structure in the wispy area of the 510 00:22:29,930 --> 00:22:28,679 clouds yeah this one so on the right on 511 00:22:32,899 --> 00:22:29,940 the right here you can see all these 512 00:22:35,600 --> 00:22:32,909 sort of wispy clouds structures that 513 00:22:38,080 --> 00:22:35,610 look like almost like a magnetic field 514 00:22:41,659 --> 00:22:38,090 and the corona or something of the Sun 515 00:22:43,279 --> 00:22:41,669 is that structure being are there any 516 00:22:46,549 --> 00:22:43,289 magnetic fields in there or is it all 517 00:22:49,970 --> 00:22:46,559 just being sculpted by stars being born 518 00:22:53,230 --> 00:22:49,980 and and the winds from all these the 519 00:22:55,779 --> 00:22:53,240 star creation well i would say that 520 00:22:58,549 --> 00:22:55,789 there are magnetic fields first of all 521 00:23:00,169 --> 00:22:58,559 they're magnetic fields are very but the 522 00:23:03,409 --> 00:23:00,179 magnetic fields are very small and very 523 00:23:06,830 --> 00:23:03,419 dense so when you collapse material down 524 00:23:08,299 --> 00:23:06,840 to create a star generally you're going 525 00:23:09,440 --> 00:23:08,309 to bring the magnetic fields along with 526 00:23:11,779 --> 00:23:09,450 it you're going to concentrate the 527 00:23:13,789 --> 00:23:11,789 magnetic field around the formation of 528 00:23:15,710 --> 00:23:13,799 the star a matter of fact one of the 529 00:23:19,399 --> 00:23:15,720 things we believe that creates these 530 00:23:22,310 --> 00:23:19,409 Jets is the magnetic field fleeing 531 00:23:24,289 --> 00:23:22,320 material off in these opposite bipolar 532 00:23:26,060 --> 00:23:24,299 magnetic field of that particular star 533 00:23:29,419 --> 00:23:26,070 though of that particular collapsed are 534 00:23:31,279 --> 00:23:29,429 okay on the sonic is there a nebula wide 535 00:23:33,289 --> 00:23:31,289 magnetic field or is it just the sum of 536 00:23:35,419 --> 00:23:33,299 all the interview nebula wide magnetic 537 00:23:38,570 --> 00:23:35,429 field would generally be very low okay 538 00:23:41,720 --> 00:23:38,580 okay so i would i'm not an expert in 539 00:23:45,049 --> 00:23:41,730 nebula but it would be my opinion that 540 00:23:47,000 --> 00:23:45,059 the magnetic field would not be strong 541 00:23:49,630 --> 00:23:47,010 enough to create the structure that you 542 00:23:52,130 --> 00:23:49,640 see in this gas here okay all right okay 543 00:23:55,669 --> 00:23:52,140 thanks all right no good question 544 00:23:57,140 --> 00:23:55,679 because i actually have have another 545 00:23:58,760 --> 00:23:57,150 point about magnetic fields in just a 546 00:24:01,899 --> 00:23:58,770 minute that's great all right play off 547 00:24:04,370 --> 00:24:01,909 of that okay so you can see the 548 00:24:07,639 --> 00:24:04,380 resolution difference here and you can 549 00:24:09,049 --> 00:24:07,649 see this jet but this jet is moving 550 00:24:12,350 --> 00:24:09,059 right this star 551 00:24:14,629 --> 00:24:12,360 is emitting this debt constantly and if 552 00:24:17,480 --> 00:24:14,639 you go back to look at it you can 553 00:24:20,899 --> 00:24:17,490 actually see the end of the jet moving 554 00:24:22,940 --> 00:24:20,909 between the 1995 image and the two 555 00:24:28,070 --> 00:24:22,950 thousand while I was taken in 2014 556 00:24:30,230 --> 00:24:28,080 released in 2015 so on the left is the 557 00:24:33,759 --> 00:24:30,240 2014 images showing you the region that 558 00:24:37,730 --> 00:24:33,769 were looking at and in the center is the 559 00:24:40,070 --> 00:24:37,740 1995 image with the arrows and then on 560 00:24:41,720 --> 00:24:40,080 the right is the 2014 image with the 561 00:24:43,669 --> 00:24:41,730 same arrows in the exact same place in 562 00:24:45,560 --> 00:24:43,679 the image so over 20 years it's moved a 563 00:24:47,749 --> 00:24:45,570 few pixels how do you have a idea what 564 00:24:50,119 --> 00:24:47,759 the distances on that are you gonna tell 565 00:24:52,100 --> 00:24:50,129 that later I don't remember I should 566 00:24:55,669 --> 00:24:52,110 have that I've ever met I when we were 567 00:24:59,299 --> 00:24:55,679 Double A s I knew that here we are two 568 00:25:00,739 --> 00:24:59,309 or three weeks out that okay yeah but 569 00:25:02,210 --> 00:25:00,749 but it can be figured out one of the 570 00:25:03,590 --> 00:25:02,220 ways you can figure it out is we know 571 00:25:05,359 --> 00:25:03,600 the what's something called the pixel 572 00:25:07,460 --> 00:25:05,369 scale of the camera in other words how 573 00:25:09,169 --> 00:25:07,470 much area each pixel on the camera 574 00:25:10,549 --> 00:25:09,179 covers and you just count the number of 575 00:25:12,379 --> 00:25:10,559 pixels and that'll tell you number of 576 00:25:14,060 --> 00:25:12,389 pixels and you need to know the distance 577 00:25:18,950 --> 00:25:14,070 to the eagle nebula which is something 578 00:25:24,919 --> 00:25:18,960 like 70 7,500 light-years by remember it 579 00:25:28,009 --> 00:25:24,929 can't be a very long the entire a pillar 580 00:25:30,440 --> 00:25:28,019 of the long pillar from the old image is 581 00:25:35,539 --> 00:25:30,450 about three light years in length so 582 00:25:38,060 --> 00:25:35,549 this is this is you know sub very very 583 00:25:41,060 --> 00:25:38,070 very small fraction of a Lightyear on 584 00:25:43,609 --> 00:25:41,070 this right so this is you know not this 585 00:25:45,499 --> 00:25:43,619 solar system scale stuff okay probably 586 00:25:48,139 --> 00:25:45,509 hundreds of a use it of astronomical 587 00:25:49,340 --> 00:25:48,149 units at best okay okay all right it's 588 00:25:50,930 --> 00:25:49,350 good we guys want to give people a sense 589 00:25:52,759 --> 00:25:50,940 of that you know how far this is moving 590 00:25:55,879 --> 00:25:52,769 and when you know how far and you have 591 00:25:58,369 --> 00:25:55,889 the time period you can get the speed 592 00:26:00,549 --> 00:25:58,379 that it's going to exactly okay so 593 00:26:04,249 --> 00:26:00,559 that's the kind of cool stuff that the 594 00:26:06,289 --> 00:26:04,259 changes from the 1995 to the 2014 or 595 00:26:08,330 --> 00:26:06,299 2015 however you want to call it an 596 00:26:11,090 --> 00:26:08,340 image but there are a lot of cool things 597 00:26:14,570 --> 00:26:11,100 that are new right so let's go back to 598 00:26:16,580 --> 00:26:14,580 this whole overview image of m6 of the 599 00:26:18,289 --> 00:26:16,590 new image and one of the things that you 600 00:26:21,470 --> 00:26:18,299 see of course that you couldn't see 601 00:26:22,640 --> 00:26:21,480 before is all this material down bottom 602 00:26:24,650 --> 00:26:22,650 right 603 00:26:27,590 --> 00:26:24,660 and what I really like about it is that 604 00:26:30,350 --> 00:26:27,600 you see the material streaming off of it 605 00:26:33,230 --> 00:26:30,360 when we looked at the old image right 606 00:26:35,390 --> 00:26:33,240 you it sort of had a sharp bottom to it 607 00:26:37,520 --> 00:26:35,400 right and you ridin really and we talked 608 00:26:40,520 --> 00:26:37,530 about the ionizing radiation the wind's 609 00:26:42,620 --> 00:26:40,530 coming down past these these pillars and 610 00:26:44,960 --> 00:26:42,630 strew pulling the material back and 611 00:26:47,030 --> 00:26:44,970 streaming material back now you get to 612 00:26:49,340 --> 00:26:47,040 see that material streaming down off of 613 00:26:52,490 --> 00:26:49,350 it and you can really tell that it is 614 00:26:54,440 --> 00:26:52,500 being pulled away by these wins and wins 615 00:26:56,420 --> 00:26:54,450 and radiation and of course you have 616 00:26:59,240 --> 00:26:56,430 this other structure down below which 617 00:27:02,930 --> 00:26:59,250 iron sort of looks like a stump to me so 618 00:27:06,350 --> 00:27:02,940 I refer to that as stub but General 619 00:27:09,890 --> 00:27:06,360 Robert hurt at JPL I don't personally 620 00:27:11,420 --> 00:27:09,900 know okay uh he looked at this image and 621 00:27:14,720 --> 00:27:11,430 he said well hey you know what let's 622 00:27:17,330 --> 00:27:14,730 single out just the center pillar right 623 00:27:19,640 --> 00:27:17,340 and you can see the pillar coming down 624 00:27:21,950 --> 00:27:19,650 and you can see the material streaming 625 00:27:23,750 --> 00:27:21,960 off of it and you already said all right 626 00:27:27,410 --> 00:27:23,760 that's a de mentor from the Harry Potter 627 00:27:30,440 --> 00:27:27,420 movies I guess oh yeah I guess it does 628 00:27:32,330 --> 00:27:30,450 not gonna look like that ever since he 629 00:27:36,110 --> 00:27:32,340 and I checked about this is like okay 630 00:27:37,850 --> 00:27:36,120 right no that's all I can see ya he's 631 00:27:40,190 --> 00:27:37,860 isolated like this and you see the 632 00:27:42,830 --> 00:27:40,200 material that's that's the visual effect 633 00:27:44,720 --> 00:27:42,840 that they did for the Harry Potter 634 00:27:47,990 --> 00:27:44,730 movies of the Dementors flying across 635 00:27:51,290 --> 00:27:48,000 the sky so we would like to call this 636 00:27:53,510 --> 00:27:51,300 the the Dementor pillar um you can admit 637 00:27:55,460 --> 00:27:53,520 but let's take a look at some of the 638 00:27:56,990 --> 00:27:55,470 other things okay so oops actually I 639 00:28:00,200 --> 00:27:57,000 didn't mean to go that quickly let me go 640 00:28:02,180 --> 00:28:00,210 back to that image right at the bottom 641 00:28:06,470 --> 00:28:02,190 of the of this pillar you can see this 642 00:28:09,020 --> 00:28:06,480 bright yellow region here right down 643 00:28:12,290 --> 00:28:09,030 here I'm going to zoom into that on my 644 00:28:16,130 --> 00:28:12,300 next slide okay so generally the bright 645 00:28:18,680 --> 00:28:16,140 yellow has been these ionization edges 646 00:28:20,840 --> 00:28:18,690 edges of dark clouds that are lit up 647 00:28:22,220 --> 00:28:20,850 yellow you can see on the left-hand side 648 00:28:26,030 --> 00:28:22,230 and Simmons you can see an ionization 649 00:28:29,540 --> 00:28:26,040 front on here right so it's dark ass on 650 00:28:33,320 --> 00:28:29,550 one side and ionized gas on yet this one 651 00:28:36,290 --> 00:28:33,330 here this big yellow spray in the center 652 00:28:38,870 --> 00:28:36,300 of this image I'm not sure what this 653 00:28:43,190 --> 00:28:38,880 and I didn't get a chance to ask the p.i 654 00:28:44,990 --> 00:28:43,200 about this this is a bright yellow what 655 00:28:49,670 --> 00:28:45,000 looks like an ionization front but it's 656 00:28:52,040 --> 00:28:49,680 not on the edge of a dark cloud this is 657 00:28:54,380 --> 00:28:52,050 what looks like you know to my untrained 658 00:28:56,930 --> 00:28:54,390 eye when I first look at it go that's a 659 00:28:59,890 --> 00:28:56,940 jet no no it's not a jet it does doesn't 660 00:29:03,230 --> 00:28:59,900 really have a star form a star 661 00:29:05,450 --> 00:29:03,240 associated with it and then you look at 662 00:29:08,060 --> 00:29:05,460 you saying well that could be ionization 663 00:29:10,430 --> 00:29:08,070 along the magnetic field we see this a 664 00:29:13,070 --> 00:29:10,440 lot in the galactic center Oh bright 665 00:29:16,370 --> 00:29:13,080 lines of strong magnetic lines going 666 00:29:18,890 --> 00:29:16,380 across there so I am not afraid to admit 667 00:29:22,990 --> 00:29:18,900 my ignorance about this it's a really 668 00:29:26,950 --> 00:29:23,000 cool feature about this image that 669 00:29:30,380 --> 00:29:26,960 smacks of you know almost either 670 00:29:31,490 --> 00:29:30,390 magnetic fields or you know it looks a 671 00:29:34,460 --> 00:29:31,500 little bit like the tendrils that we 672 00:29:37,370 --> 00:29:34,470 sometimes see in supernova remnants 673 00:29:39,620 --> 00:29:37,380 right hmm and I don't know did you ever 674 00:29:40,850 --> 00:29:39,630 get a discussion of anybody that they 675 00:29:42,650 --> 00:29:40,860 told you what this is don't know I 676 00:29:44,300 --> 00:29:42,660 haven't I haven't I haven't heard 677 00:29:47,330 --> 00:29:44,310 anybody be able to tell us what that is 678 00:29:50,450 --> 00:29:47,340 yet yeah so I mean this is a really cool 679 00:29:52,250 --> 00:29:50,460 thing and you know I like to say that 680 00:29:54,140 --> 00:29:52,260 you know some of the best days for an 681 00:29:55,420 --> 00:29:54,150 astronomer or when they realize they 682 00:29:57,980 --> 00:29:55,430 don't know what they're talking about 683 00:30:00,200 --> 00:29:57,990 when you recognize your ignorance then 684 00:30:01,460 --> 00:30:00,210 there's something new to discover and 685 00:30:04,160 --> 00:30:01,470 this would be something new for me to 686 00:30:06,230 --> 00:30:04,170 discover in terms of this cool stuff 687 00:30:07,580 --> 00:30:06,240 here and this is a big this is something 688 00:30:09,320 --> 00:30:07,590 we would not have gotten with the older 689 00:30:12,710 --> 00:30:09,330 camera anyway so the new what the new 690 00:30:13,820 --> 00:30:12,720 field of view was something made putted 691 00:30:16,070 --> 00:30:13,830 you know seeing this was made possible 692 00:30:17,240 --> 00:30:16,080 what a new field of you exactly this is 693 00:30:19,520 --> 00:30:17,250 outside the field of view of the old 694 00:30:21,530 --> 00:30:19,530 camera right also outside the field of 695 00:30:25,840 --> 00:30:21,540 view of the old camera is this 696 00:30:33,190 --> 00:30:31,280 these are smaller versions of the 697 00:30:35,170 --> 00:30:33,200 pillars writ large in the big image 698 00:30:38,210 --> 00:30:35,180 matter of fact the one on the right 699 00:30:41,720 --> 00:30:38,220 Zoltan Levay the image processor refers 700 00:30:46,670 --> 00:30:41,730 to that as mini me you know reference to 701 00:30:48,560 --> 00:30:46,680 what were those movies like my herb like 702 00:30:49,850 --> 00:30:48,570 Austin Powers Austin Powers yes the 703 00:30:52,700 --> 00:30:49,860 Austin Powers movies k 704 00:30:55,610 --> 00:30:52,710 so that many me and that uh well here we 705 00:30:58,100 --> 00:30:55,620 have a Hubble mini me in the Eagle 706 00:31:00,620 --> 00:30:58,110 Nebula these pillars and really when you 707 00:31:04,310 --> 00:31:00,630 look around the the nebula you see a 708 00:31:07,190 --> 00:31:04,320 bunch of these small agglomerations of 709 00:31:09,650 --> 00:31:07,200 dense gas that are being eaten away now 710 00:31:12,260 --> 00:31:09,660 these i would expect are going to be 711 00:31:14,060 --> 00:31:12,270 eaten away before they would have any 712 00:31:16,310 --> 00:31:14,070 chance to form stars you might look at 713 00:31:19,310 --> 00:31:16,320 them and say okay there's a dense not of 714 00:31:21,680 --> 00:31:19,320 gas here maybe perhaps at Michaelmas 715 00:31:25,700 --> 00:31:21,690 star but at this scale it's not enough 716 00:31:28,970 --> 00:31:25,710 probably to resist the the erosion 717 00:31:31,450 --> 00:31:28,980 before it forms a star so one of the 718 00:31:33,770 --> 00:31:31,460 things you can learn about is that the 719 00:31:37,070 --> 00:31:33,780 process of star formation after other 720 00:31:39,440 --> 00:31:37,080 stars have formed and are then create 721 00:31:42,080 --> 00:31:39,450 these winds and ionizing radiation that 722 00:31:46,280 --> 00:31:42,090 eats away the gas it actually will 723 00:31:49,310 --> 00:31:46,290 inhibit other stars from forming next 724 00:31:54,230 --> 00:31:49,320 all right so that's it for the visible 725 00:31:56,919 --> 00:31:54,240 light image but there's more because the 726 00:32:01,640 --> 00:31:56,929 wide field camera 3 doesn't have just 727 00:32:04,240 --> 00:32:01,650 visible light it also can do infrared so 728 00:32:07,360 --> 00:32:04,250 here is the new visible light image and 729 00:32:10,789 --> 00:32:07,370 using the infrared portion of it we got 730 00:32:14,480 --> 00:32:10,799 this image in infrared yeah that's my 731 00:32:16,820 --> 00:32:14,490 favorite part and just to have fun I'm 732 00:32:19,970 --> 00:32:16,830 going to I'm going to blink back go go 733 00:32:22,490 --> 00:32:19,980 back to the visible light image and then 734 00:32:24,020 --> 00:32:22,500 go forward to the infrared right and 735 00:32:26,060 --> 00:32:24,030 first thing that stands out or all the 736 00:32:29,330 --> 00:32:26,070 stars that you can see right amazing 737 00:32:32,690 --> 00:32:29,340 number of stars yes with the infrared 738 00:32:35,630 --> 00:32:32,700 you have longer wavelengths you will see 739 00:32:38,120 --> 00:32:35,640 through some of the gas that you cannot 740 00:32:39,620 --> 00:32:38,130 see through in optical light and so 741 00:32:41,870 --> 00:32:39,630 you'll see through and you see all the 742 00:32:44,000 --> 00:32:41,880 stars in the field so all the dark stuff 743 00:32:46,700 --> 00:32:44,010 that you see now is the stuff that's 744 00:32:49,220 --> 00:32:46,710 even too thick for infrared radiation to 745 00:32:50,930 --> 00:32:49,230 get exactly right right so the longer 746 00:32:53,030 --> 00:32:50,940 wavelengths can pass through low-density 747 00:32:55,159 --> 00:32:53,040 gas can't pass through the really high 748 00:32:58,310 --> 00:32:55,169 density guess so with left is the really 749 00:33:01,370 --> 00:32:58,320 high density gas and also the fact that 750 00:33:03,650 --> 00:33:01,380 stars glow appear different in the 751 00:33:04,910 --> 00:33:03,660 infrared right with the 752 00:33:07,940 --> 00:33:04,920 you're going to pick out the cooler 753 00:33:10,340 --> 00:33:07,950 stars and there are more cool stars in 754 00:33:12,550 --> 00:33:10,350 universe then there are hot stars in the 755 00:33:16,820 --> 00:33:12,560 universe so you're also going to get 756 00:33:18,950 --> 00:33:16,830 extra an extra complement of started 757 00:33:20,780 --> 00:33:18,960 simply because you're bringing up the 758 00:33:24,470 --> 00:33:20,790 cool stars that you otherwise wouldn't 759 00:33:27,770 --> 00:33:24,480 okay yep so let's put the two of them 760 00:33:29,900 --> 00:33:27,780 side-by-side and again we were talking 761 00:33:32,660 --> 00:33:29,910 about the the number of stars that you 762 00:33:35,840 --> 00:33:32,670 can see here and you can get a feeling 763 00:33:37,700 --> 00:33:35,850 that the structure is similar but that 764 00:33:40,190 --> 00:33:37,710 they're slightly different and one of 765 00:33:40,940 --> 00:33:40,200 things i like to think about because you 766 00:33:45,050 --> 00:33:40,950 know we do three-dimensional 767 00:33:46,670 --> 00:33:45,060 visualizations right and so when we're 768 00:33:49,850 --> 00:33:46,680 looking at the visible surface of a 769 00:33:52,220 --> 00:33:49,860 nebula whether it's this nebula or other 770 00:33:54,650 --> 00:33:52,230 nebula oh because the infrared 771 00:33:56,000 --> 00:33:54,660 penetrates deeper you're actually 772 00:33:58,150 --> 00:33:56,010 looking at sort of a three-dimensional 773 00:34:00,920 --> 00:33:58,160 surface underneath the visible surface 774 00:34:03,230 --> 00:34:00,930 so you can think of the infrared of 775 00:34:05,510 --> 00:34:03,240 seeing you know below if if the 776 00:34:07,910 --> 00:34:05,520 invisible light is the skin skin deep 777 00:34:09,380 --> 00:34:07,920 the infrared you know those goes a 778 00:34:11,450 --> 00:34:09,390 little bit deeper and you'll see that 779 00:34:12,950 --> 00:34:11,460 the organs and other things the details 780 00:34:15,590 --> 00:34:12,960 under some of the some of the details 781 00:34:18,169 --> 00:34:15,600 underneath the skin of the nebula and 782 00:34:20,270 --> 00:34:18,179 you can see a lot of structure so let's 783 00:34:22,490 --> 00:34:20,280 go and let's do the same thing we did 784 00:34:25,100 --> 00:34:22,500 with the visible light image during 1995 785 00:34:28,120 --> 00:34:25,110 2015 but now we're going to do both of 786 00:34:32,419 --> 00:34:28,130 the 2015 images visible versus infrared 787 00:34:34,460 --> 00:34:32,429 so we start with that pillar that the 788 00:34:37,490 --> 00:34:34,470 central central region where we had that 789 00:34:39,260 --> 00:34:37,500 smokestack you can see here on the left 790 00:34:43,010 --> 00:34:39,270 hand side there is the smoke stack it 791 00:34:45,409 --> 00:34:43,020 with visible light and then over on the 792 00:34:47,900 --> 00:34:45,419 right hand side you can see the infrared 793 00:34:50,000 --> 00:34:47,910 version of it and you can see an 794 00:34:53,390 --> 00:34:50,010 amazingly bright star are at the top 795 00:34:55,640 --> 00:34:53,400 there right I'm not sure that that's the 796 00:34:58,670 --> 00:34:55,650 star that is for our that formed at the 797 00:35:00,500 --> 00:34:58,680 top there okay I tried looking at it in 798 00:35:02,390 --> 00:35:00,510 great detail and I couldn't convince 799 00:35:04,250 --> 00:35:02,400 myself that it absolutely had to be that 800 00:35:06,260 --> 00:35:04,260 a star that reformed you to top the 801 00:35:07,340 --> 00:35:06,270 smokestack but it's certain sir it looks 802 00:35:08,630 --> 00:35:07,350 like it doesn't it yeah and if you look 803 00:35:11,480 --> 00:35:08,640 at the top of the other one you can see 804 00:35:13,460 --> 00:35:11,490 a star there as well then there's like 805 00:35:14,990 --> 00:35:13,470 on the right on the left image it looks 806 00:35:17,550 --> 00:35:15,000 like there's something right behind that 807 00:35:18,960 --> 00:35:17,560 gas cloud that is 808 00:35:20,670 --> 00:35:18,970 raining pretty brightly and it looks 809 00:35:22,590 --> 00:35:20,680 like it's coming through in the infrared 810 00:35:26,640 --> 00:35:22,600 image but maybe you're right maybe it's 811 00:35:29,280 --> 00:35:26,650 just a it could just get a coincidental 812 00:35:31,590 --> 00:35:29,290 placement and so I wouldn't want to tell 813 00:35:34,950 --> 00:35:31,600 our viewers that it absolutely is unless 814 00:35:36,420 --> 00:35:34,960 I knew I knew for sure but it you can 815 00:35:38,490 --> 00:35:36,430 you can see but the other thing that you 816 00:35:40,710 --> 00:35:38,500 can see is that if you look in the left 817 00:35:43,620 --> 00:35:40,720 hand image you can see these two stars 818 00:35:44,820 --> 00:35:43,630 in the lower right okay yeah those stars 819 00:35:46,890 --> 00:35:44,830 and lower right you find the 820 00:35:50,310 --> 00:35:46,900 corresponding stars in the right hand 821 00:35:53,310 --> 00:35:50,320 image and they're honking bright yeah 822 00:35:56,430 --> 00:35:53,320 now so a faint star in the visible light 823 00:36:00,030 --> 00:35:56,440 image might become a very bright star in 824 00:36:02,150 --> 00:36:00,040 the infrared age okay let's go to the 825 00:36:05,010 --> 00:36:02,160 top of the center pit central pillar 826 00:36:08,370 --> 00:36:05,020 again visible light on the left infrared 827 00:36:10,020 --> 00:36:08,380 on the right this is one of the times it 828 00:36:12,570 --> 00:36:10,030 you know remember the Horsehead Nebula 829 00:36:14,370 --> 00:36:12,580 Tony mm-hmm oh yeah when we went from 830 00:36:16,890 --> 00:36:14,380 the visible light image you saw almost 831 00:36:19,170 --> 00:36:16,900 nothing visible like the horse head and 832 00:36:21,570 --> 00:36:19,180 then went into the infrared you saw an 833 00:36:24,510 --> 00:36:21,580 amount of landscape that sort of 834 00:36:26,550 --> 00:36:24,520 appeared by looking at it this is sort 835 00:36:28,920 --> 00:36:26,560 of the opposite I actually feel like we 836 00:36:32,900 --> 00:36:28,930 lose a little bit of detail in going to 837 00:36:35,790 --> 00:36:32,910 the infrared here we don't get as much 838 00:36:37,950 --> 00:36:35,800 there's a awful lot of dense gas here 839 00:36:39,480 --> 00:36:37,960 right yeah but it seems to me like yes 840 00:36:41,790 --> 00:36:39,490 that's what it tells me is it just how 841 00:36:44,130 --> 00:36:41,800 thick and dense that material is but 842 00:36:47,490 --> 00:36:44,140 also that the stuff the structure that 843 00:36:49,410 --> 00:36:47,500 you see on the left is actually a pretty 844 00:36:51,660 --> 00:36:49,420 superficial it's not and it's not doing 845 00:36:54,030 --> 00:36:51,670 much in the way of infrared emissions at 846 00:36:56,490 --> 00:36:54,040 all because it goes away it's dark in 847 00:36:58,320 --> 00:36:56,500 the infrared so right so I mean this is 848 00:37:01,410 --> 00:36:58,330 it this is a seriously thick mountain 849 00:37:03,780 --> 00:37:01,420 top yeah this is a you know this is a 850 00:37:05,730 --> 00:37:03,790 dense Club of gas that's really there's 851 00:37:08,460 --> 00:37:05,740 a lot of stuff there all right you can 852 00:37:11,310 --> 00:37:08,470 see how that that tiny star and the 853 00:37:14,100 --> 00:37:11,320 lowest in the center down bottom becomes 854 00:37:15,750 --> 00:37:14,110 a nice bright star in the infrared the 855 00:37:18,480 --> 00:37:15,760 other thing that you see is you do see 856 00:37:20,280 --> 00:37:18,490 some star formation I do see some star 857 00:37:23,570 --> 00:37:20,290 formation up here at the top of the 858 00:37:27,150 --> 00:37:23,580 pillar you see these two bright stars 859 00:37:30,570 --> 00:37:27,160 okay these look to me like newborn stars 860 00:37:31,350 --> 00:37:30,580 you can see the red red region on the 861 00:37:33,090 --> 00:37:31,360 left 862 00:37:35,490 --> 00:37:33,100 where you can see one of those stars 863 00:37:38,370 --> 00:37:35,500 look like it is just formed in the top 864 00:37:41,370 --> 00:37:38,380 of the pillar and then you bet you see 865 00:37:45,060 --> 00:37:41,380 through a bit and see another one here 866 00:37:47,850 --> 00:37:45,070 in the infrared so again looking in and 867 00:37:50,430 --> 00:37:47,860 seeing details of the star creation 868 00:37:53,580 --> 00:37:50,440 that's probably going on inside of these 869 00:37:56,370 --> 00:37:53,590 pillars and the jellyfish's is really 870 00:37:59,370 --> 00:37:56,380 faded out mm-hmm you know you could 871 00:38:01,710 --> 00:37:59,380 barely see it now in the infrared that 872 00:38:04,590 --> 00:38:01,720 star formation is shown also in detail 873 00:38:07,410 --> 00:38:04,600 at the top of the tall pillar so if we 874 00:38:08,910 --> 00:38:07,420 go to the top of a left pillar again we 875 00:38:10,590 --> 00:38:08,920 see you can see how all of these tall 876 00:38:15,120 --> 00:38:10,600 little fingers these small little 877 00:38:17,340 --> 00:38:15,130 fingers are actually now in the infrared 878 00:38:22,950 --> 00:38:17,350 aren't quite as detail but they're also 879 00:38:25,680 --> 00:38:22,960 Spade in all of this evaporating gas so 880 00:38:28,230 --> 00:38:25,690 all of this bluish grayish light in the 881 00:38:31,560 --> 00:38:28,240 infrared image is that evaporating gas 882 00:38:34,350 --> 00:38:31,570 that sort of colors that the gift gives 883 00:38:36,150 --> 00:38:34,360 us some color in front of the gas so 884 00:38:38,760 --> 00:38:36,160 sometimes I'm not sure we can see just 885 00:38:41,250 --> 00:38:38,770 how much detail how much a dense gas 886 00:38:45,000 --> 00:38:41,260 there is because there's all of this 887 00:38:47,300 --> 00:38:45,010 evaporating gas on top of it and you can 888 00:38:50,850 --> 00:38:47,310 really see the detail of star formation 889 00:38:53,280 --> 00:38:50,860 if you look in this sent this region 890 00:38:55,560 --> 00:38:53,290 here so i put these arrows at the same 891 00:38:57,330 --> 00:38:55,570 spot in each image and you can see on 892 00:39:00,360 --> 00:38:57,340 the visible light image there's that 893 00:39:01,710 --> 00:39:00,370 little red glow all right look at that 894 00:39:04,410 --> 00:39:01,720 and yeah you can still see it but it's 895 00:39:06,210 --> 00:39:04,420 brighter and the provide yeah and the 896 00:39:08,370 --> 00:39:06,220 infrared you can see that there's star 897 00:39:10,620 --> 00:39:08,380 formation going on in there that little 898 00:39:14,940 --> 00:39:10,630 red glow a place where air star looks 899 00:39:16,770 --> 00:39:14,950 like it's for me has become eaten away 900 00:39:19,230 --> 00:39:16,780 you can start to see the physic and 901 00:39:20,970 --> 00:39:19,240 there's a cavity in there and that's 902 00:39:22,320 --> 00:39:20,980 where the stars won't you this is how 903 00:39:26,040 --> 00:39:22,330 what I mean about you have to look 904 00:39:27,780 --> 00:39:26,050 deeper inside to see what's going on and 905 00:39:30,210 --> 00:39:27,790 when you've got these stars somewhat 906 00:39:32,880 --> 00:39:30,220 near the surface that around them 907 00:39:36,000 --> 00:39:32,890 is forming you can actually infrared see 908 00:39:37,850 --> 00:39:36,010 them on Sienna now this of course is 909 00:39:40,170 --> 00:39:37,860 just what we call the near-infrared 910 00:39:42,090 --> 00:39:40,180 bubble doesn't go very far into the 911 00:39:43,350 --> 00:39:42,100 infrared we need something like Spitzer 912 00:39:45,100 --> 00:39:43,360 or the upcoming james webb space 913 00:39:47,590 --> 00:39:45,110 telescope to see 914 00:39:50,410 --> 00:39:47,600 deeper into this and then you can see 915 00:39:52,450 --> 00:39:50,420 all sorts of interesting and more detail 916 00:39:54,190 --> 00:39:52,460 structures inside matter of fact 917 00:39:57,310 --> 00:39:54,200 sometimes when I'm comparing Hubble and 918 00:40:00,040 --> 00:39:57,320 Spitzer images it's really hard because 919 00:40:01,780 --> 00:40:00,050 you're looking so deep into it that the 920 00:40:05,950 --> 00:40:01,790 structures don't don't really match 921 00:40:09,420 --> 00:40:05,960 sometimes the structures don't match so 922 00:40:11,800 --> 00:40:09,430 oh alright one more thing all right 923 00:40:16,270 --> 00:40:11,810 actually two two more things to more 924 00:40:17,860 --> 00:40:16,280 things of this the real difference when 925 00:40:19,690 --> 00:40:17,870 I look at the visible light versus the 926 00:40:22,090 --> 00:40:19,700 infrared light is actually from a much 927 00:40:24,670 --> 00:40:22,100 larger perspective so here we have that 928 00:40:26,650 --> 00:40:24,680 leftmost pillar on the top and when you 929 00:40:29,680 --> 00:40:26,660 look at the visible light image over 930 00:40:32,800 --> 00:40:29,690 here it feels like it's a solid pillar 931 00:40:35,800 --> 00:40:32,810 up and down right that you know but we 932 00:40:38,470 --> 00:40:35,810 know that it's only required that the 933 00:40:42,280 --> 00:40:38,480 top part be dense and that the part down 934 00:40:45,460 --> 00:40:42,290 here could be in shadow well when you go 935 00:40:48,070 --> 00:40:45,470 to the infrared what do we see well 936 00:40:51,700 --> 00:40:48,080 actually we see a whole lot of emptiness 937 00:40:55,120 --> 00:40:51,710 yeah okay there is a really dense cloud 938 00:40:57,310 --> 00:40:55,130 up at the top but all of them you're 939 00:41:01,480 --> 00:40:57,320 seeing so many stars through here and 940 00:41:04,960 --> 00:41:01,490 not much gas that this is shadow we are 941 00:41:07,150 --> 00:41:04,970 seeing emptiness and the infrared that 942 00:41:09,460 --> 00:41:07,160 we otherwise couldn't see using the 943 00:41:11,350 --> 00:41:09,470 visible light and this is one of the 944 00:41:13,810 --> 00:41:11,360 most important things that infrared 945 00:41:17,050 --> 00:41:13,820 allows us to do in looking through the 946 00:41:19,210 --> 00:41:17,060 low-density gas we get to see her I I 947 00:41:21,850 --> 00:41:19,220 hate to say it's like an x-ray because 948 00:41:26,200 --> 00:41:21,860 that mixes a lot of flight metaphors 949 00:41:28,660 --> 00:41:26,210 yeah yeah but you get to look through 950 00:41:30,760 --> 00:41:28,670 the the visible surface and see what's 951 00:41:34,060 --> 00:41:30,770 truly underneath where it is the real 952 00:41:36,550 --> 00:41:34,070 against gas underneath this and you can 953 00:41:38,950 --> 00:41:36,560 see that that pillar isn't a pillar and 954 00:41:40,480 --> 00:41:38,960 if you study the apes' image you 955 00:41:44,950 --> 00:41:40,490 actually can see that the pillar is 956 00:41:47,710 --> 00:41:44,960 composed of a segment of several clumps 957 00:41:49,150 --> 00:41:47,720 with their shadows behind them to create 958 00:41:54,880 --> 00:41:49,160 that big long through like your own 959 00:41:57,850 --> 00:41:54,890 killer well that's kind of cool and the 960 00:41:58,599 --> 00:41:57,860 other thing is that if you look you will 961 00:42:01,599 --> 00:41:58,609 find some 962 00:42:05,289 --> 00:42:01,609 bright stars and the infrared that do 963 00:42:06,670 --> 00:42:05,299 not show up in the visible so I know 964 00:42:08,950 --> 00:42:06,680 you're looking at this gone well what's 965 00:42:12,759 --> 00:42:08,960 he comparing here okay this is a fact 966 00:42:14,079 --> 00:42:12,769 same region from both images well you'd 967 00:42:16,509 --> 00:42:14,089 never know that that looks like that 968 00:42:18,279 --> 00:42:16,519 it's completely different did you look 969 00:42:20,920 --> 00:42:18,289 at this and go what's he doing okay so 970 00:42:22,690 --> 00:42:20,930 let me guide your eye here okay on the 971 00:42:26,140 --> 00:42:22,700 left-hand image you see these four stars 972 00:42:28,779 --> 00:42:26,150 here bing bang yup lingo and bongo right 973 00:42:32,339 --> 00:42:28,789 come over to the right-hand image and 974 00:42:35,829 --> 00:42:32,349 you see the same four stars bing bang 975 00:42:38,620 --> 00:42:35,839 lingo and bongo those are technical term 976 00:42:44,799 --> 00:42:38,630 you say yeah I years do not try this at 977 00:42:47,380 --> 00:42:44,809 all you has a name that too where did 978 00:42:50,349 --> 00:42:47,390 these four honking big infrared stars 979 00:42:52,329 --> 00:42:50,359 come I know they are really bright yeah 980 00:42:54,190 --> 00:42:52,339 and I remember you and I were at the 981 00:42:56,229 --> 00:42:54,200 double-a s and we were looking at this 982 00:42:58,210 --> 00:42:56,239 on the touchscreen and we said oh those 983 00:43:00,039 --> 00:42:58,220 four stars have to be these four smaller 984 00:43:01,900 --> 00:43:00,049 stars and because we were just sliding 985 00:43:04,509 --> 00:43:01,910 back and forth we weren't able to to 986 00:43:06,759 --> 00:43:04,519 crossfade back and forth and so when I 987 00:43:08,410 --> 00:43:06,769 brought this into the image processing 988 00:43:09,609 --> 00:43:08,420 program and I aligned them and 989 00:43:16,920 --> 00:43:09,619 everything and I went down here is like 990 00:43:22,180 --> 00:43:16,930 oh yeah those aren't oh are you there 991 00:43:24,220 --> 00:43:22,190 must be behind Wow the green gas of a 992 00:43:25,930 --> 00:43:24,230 blue gas the oxygen emitting part of the 993 00:43:28,200 --> 00:43:25,940 nebula and that only with the infrared 994 00:43:31,499 --> 00:43:28,210 do you see through it in order to see 995 00:43:35,799 --> 00:43:31,509 these really really really bright stars 996 00:43:39,609 --> 00:43:35,809 cool all right so that takes us to our 997 00:43:42,339 --> 00:43:39,619 final slide of today's presentation on 998 00:43:45,460 --> 00:43:42,349 the left is the 1995 image the center is 999 00:43:49,210 --> 00:43:45,470 the 2015 visible light and on the right 1000 00:43:52,120 --> 00:43:49,220 is the 2015 infrared we have we visited 1001 00:43:54,690 --> 00:43:52,130 a legend there are so much cool stuff to 1002 00:43:57,640 --> 00:43:54,700 looking here I gotta say that the 1003 00:43:59,920 --> 00:43:57,650 visible light image and all 60 million 1004 00:44:02,620 --> 00:43:59,930 pixel glory is available for everybody 1005 00:44:04,690 --> 00:44:02,630 not just astrophysicist the public can 1006 00:44:07,960 --> 00:44:04,700 download it and look at all these cool 1007 00:44:10,029 --> 00:44:07,970 cool details yourself the infrared image 1008 00:44:12,339 --> 00:44:10,039 is something like what I think that's 1009 00:44:15,910 --> 00:44:12,349 around 16 million pixels 1010 00:44:17,620 --> 00:44:15,920 as well so there's lots of all the data 1011 00:44:20,829 --> 00:44:17,630 one of the best things about Hubble is 1012 00:44:22,900 --> 00:44:20,839 it's not just the astronomers on the 1013 00:44:25,359 --> 00:44:22,910 mountaintops telescope it is the 1014 00:44:27,309 --> 00:44:25,369 people's telescope and all of our data 1015 00:44:29,259 --> 00:44:27,319 all of our work is paid for by the 1016 00:44:31,239 --> 00:44:29,269 public so all of our data is made 1017 00:44:33,219 --> 00:44:31,249 available to the plant so if you've got 1018 00:44:35,620 --> 00:44:33,229 a whole site and you want to study these 1019 00:44:37,719 --> 00:44:35,630 the images and details have at it and 1020 00:44:40,989 --> 00:44:37,729 enjoy nobody knows that better than the 1021 00:44:44,499 --> 00:44:40,999 person who's question I want to get to 1022 00:44:48,009 --> 00:44:44,509 right away Judy Schmidt she is hot hi 1023 00:44:50,229 --> 00:44:48,019 Judy she's always a good person to talk 1024 00:44:52,420 --> 00:44:50,239 to about Hubble images and using the 1025 00:44:55,269 --> 00:44:52,430 data things like that but she's asking a 1026 00:44:57,069 --> 00:44:55,279 question she says I like to call that 1027 00:45:00,489 --> 00:44:57,079 reddish protrusion from the center 1028 00:45:02,680 --> 00:45:00,499 pillar a kabuki mask I wonder I wonder 1029 00:45:04,690 --> 00:45:02,690 though I'm gonna put it up here I wonder 1030 00:45:06,039 --> 00:45:04,700 why its composition is a little 1031 00:45:08,700 --> 00:45:06,049 different from the rest of the pillar 1032 00:45:11,620 --> 00:45:08,710 getting you got any response to that um 1033 00:45:14,440 --> 00:45:11,630 you know she calls it a kabuki mask I 1034 00:45:21,099 --> 00:45:14,450 actually looked at it as an ear for guys 1035 00:45:23,049 --> 00:45:21,109 in a pair the red color there I don't 1036 00:45:27,789 --> 00:45:23,059 have a good guess for it to be honest 1037 00:45:29,650 --> 00:45:27,799 with you I know that I mean the red in 1038 00:45:36,489 --> 00:45:29,660 that image has got to be got to be 1039 00:45:38,109 --> 00:45:36,499 nitrogen and you know let me go back to 1040 00:45:41,049 --> 00:45:38,119 that let me see if I if I and I can 1041 00:45:44,559 --> 00:45:41,059 quickly go back to that image I'm going 1042 00:45:48,279 --> 00:45:44,569 to scan through real quick there we go 1043 00:45:50,709 --> 00:45:48,289 what's right spot okay so on the left 1044 00:45:55,989 --> 00:45:50,719 you know that I believe this is what 1045 00:45:58,509 --> 00:45:55,999 Judy's calling kabuki mask it's not so 1046 00:46:01,779 --> 00:45:58,519 much the red dot on the left hand side 1047 00:46:04,719 --> 00:46:01,789 of it that that seems reasonable it's 1048 00:46:09,549 --> 00:46:04,729 these sort of scallop shapes around it 1049 00:46:12,789 --> 00:46:09,559 that I don't quite I don't know I don't 1050 00:46:13,900 --> 00:46:12,799 quite know how that I sort of look at 1051 00:46:18,219 --> 00:46:13,910 those things and I started think of 1052 00:46:20,349 --> 00:46:18,229 winds its etc from from from newborn 1053 00:46:24,579 --> 00:46:20,359 stars to blow out because this looks 1054 00:46:26,140 --> 00:46:24,589 like billowing out of a wind you know 1055 00:46:28,720 --> 00:46:26,150 you know as you as you blow out 1056 00:46:30,930 --> 00:46:28,730 bubbles and such but that's going to be 1057 00:46:34,299 --> 00:46:30,940 my best idea for something like that 1058 00:46:36,309 --> 00:46:34,309 okay all right well it's yeah it's it's 1059 00:46:37,750 --> 00:46:36,319 uh it's gonna be a while I guess before 1060 00:46:39,220 --> 00:46:37,760 we can find out everything there is to 1061 00:46:41,609 --> 00:46:39,230 know about all these images but that's a 1062 00:46:44,430 --> 00:46:41,619 good question Judy Nikolas has a comment 1063 00:46:47,440 --> 00:46:44,440 or actually his questions are about the 1064 00:46:49,779 --> 00:46:47,450 differences in resolutions he's asking 1065 00:46:51,849 --> 00:46:49,789 is it really only mrs. between the two 1066 00:46:54,849 --> 00:46:51,859 cameras is it really only the better 1067 00:46:58,990 --> 00:46:54,859 resolution on the newer images or also 1068 00:47:00,789 --> 00:46:59,000 some some more 2015 ish image processing 1069 00:47:02,710 --> 00:47:00,799 so to what extent do you think the 1070 00:47:04,210 --> 00:47:02,720 details that we're seeing or do to image 1071 00:47:09,180 --> 00:47:04,220 prop the better image processing 1072 00:47:14,049 --> 00:47:11,470 there's a little bit of that ok so first 1073 00:47:16,510 --> 00:47:14,059 of all there's the cameras with pick two 1074 00:47:20,319 --> 00:47:16,520 is a tenth of an arcsecond per pixel why 1075 00:47:23,500 --> 00:47:20,329 twisted with c3 is a 2020 a second per 1076 00:47:26,740 --> 00:47:23,510 pixel so that's definitely there to the 1077 00:47:28,779 --> 00:47:26,750 detectors are more efficient and well 1078 00:47:32,620 --> 00:47:28,789 they can do this same image in shorter 1079 00:47:34,690 --> 00:47:32,630 time but they are our understanding of 1080 00:47:39,309 --> 00:47:34,700 how to process the data is of course 1081 00:47:41,200 --> 00:47:39,319 better way we've processed in the with 1082 00:47:43,480 --> 00:47:41,210 pic to image you know we had only two 1083 00:47:45,220 --> 00:47:43,490 years of working with with it too we've 1084 00:47:47,049 --> 00:47:45,230 had five years of working with whiskey 1085 00:47:49,930 --> 00:47:47,059 three computers are much much much 1086 00:47:51,519 --> 00:47:49,940 faster we know how to remove errors 1087 00:47:53,470 --> 00:47:51,529 there are some errors by the way that if 1088 00:47:56,859 --> 00:47:53,480 you compare the two you can go oh that's 1089 00:47:59,950 --> 00:47:56,869 not a star that's a that's a glitch from 1090 00:48:01,930 --> 00:47:59,960 the bright star creating a a a peak in 1091 00:48:04,930 --> 00:48:01,940 the CCD so there's some of those small 1092 00:48:07,000 --> 00:48:04,940 things there so it's improvement in 1093 00:48:09,490 --> 00:48:07,010 resolution improvement in the detectors 1094 00:48:12,279 --> 00:48:09,500 and improvement in our processing that 1095 00:48:16,650 --> 00:48:12,289 do that to help all of our gaining much 1096 00:48:18,849 --> 00:48:16,660 more sensory from these images right and 1097 00:48:24,160 --> 00:48:18,859 one point I'd like to make is that you 1098 00:48:26,200 --> 00:48:24,170 can also with the if when we have the 1099 00:48:27,760 --> 00:48:26,210 data from the original camera there's 1100 00:48:29,109 --> 00:48:27,770 nothing to prevent you from reprocessing 1101 00:48:30,609 --> 00:48:29,119 and using new techniques once you 1102 00:48:32,319 --> 00:48:30,619 understand how to better do things don't 1103 00:48:34,150 --> 00:48:32,329 if he can't really do is maybe take 1104 00:48:35,170 --> 00:48:34,160 different calibration images or things 1105 00:48:36,640 --> 00:48:35,180 like that because the camera is no 1106 00:48:37,690 --> 00:48:36,650 longer there but there's nothing to 1107 00:48:39,430 --> 00:48:37,700 prevent you from using the newer 1108 00:48:43,780 --> 00:48:39,440 techniques right 1109 00:48:45,490 --> 00:48:43,790 so okay so I think I will that's I mean 1110 00:48:47,500 --> 00:48:45,500 maybe look to see if there's any any 1111 00:48:51,400 --> 00:48:47,510 more questions around i'm looking at 1112 00:48:54,099 --> 00:48:51,410 hubbell hangouts I don't see that I 1113 00:48:55,630 --> 00:48:54,109 don't see any tweets or anything so the 1114 00:48:58,599 --> 00:48:55,640 only other question is from zigzagging 1115 00:49:02,710 --> 00:48:58,609 I'm not quite sure how to interpret this 1116 00:49:05,470 --> 00:49:02,720 but we have those Weston's of the rate 1117 00:49:11,849 --> 00:49:05,480 of mass expansion oh it just disappeared 1118 00:49:15,370 --> 00:49:11,859 great a the idea of the rate of mass 1119 00:49:16,630 --> 00:49:15,380 expansion in miles per hour we talked 1120 00:49:18,400 --> 00:49:16,640 about that briefly if you're talking 1121 00:49:20,890 --> 00:49:18,410 about the the increase in the rate of 1122 00:49:23,710 --> 00:49:20,900 the or the movement of some of those 1123 00:49:25,240 --> 00:49:23,720 features you can know we didn't know it 1124 00:49:27,339 --> 00:49:25,250 on top of our heads but you can figure 1125 00:49:30,579 --> 00:49:27,349 it out once you wouldn't by knowing for 1126 00:49:34,300 --> 00:49:30,589 pixel scale which is the the area on a 1127 00:49:35,890 --> 00:49:34,310 side of each pixel and then count the 1128 00:49:38,230 --> 00:49:35,900 number of pixels and since we know the 1129 00:49:40,000 --> 00:49:38,240 time there wasn't like you know 20 years 1130 00:49:42,220 --> 00:49:40,010 have gone by we can kind of get a speed 1131 00:49:44,230 --> 00:49:42,230 from that as well so that's that's the 1132 00:49:46,240 --> 00:49:44,240 way in which you would figure it out the 1133 00:49:50,050 --> 00:49:46,250 scale on this is going to be an order of 1134 00:49:52,000 --> 00:49:50,060 a thousand kilometers a second okay the 1135 00:49:54,700 --> 00:49:52,010 solar wind okay the suns and midlands 1136 00:49:57,160 --> 00:49:54,710 star the solar wind from the Sun blows 1137 00:50:00,069 --> 00:49:57,170 out at 400 kilometers a second regularly 1138 00:50:03,069 --> 00:50:00,079 and 800 kilometers second vertically the 1139 00:50:04,630 --> 00:50:03,079 Jets are going to be proud at faster 1140 00:50:07,059 --> 00:50:04,640 speeds than that so there'll be a few 1141 00:50:09,010 --> 00:50:07,069 thousand kilometers per second maybe as 1142 00:50:14,500 --> 00:50:09,020 high as 10 10 or 20,000 kilometers a 1143 00:50:20,319 --> 00:50:14,510 second now the kilometer per second if 1144 00:50:22,510 --> 00:50:20,329 you do the map ends up being what do we 1145 00:50:24,670 --> 00:50:22,520 get 30 kilometers per second is about a 1146 00:50:28,180 --> 00:50:24,680 hundred eight thousand hundred thousand 1147 00:50:31,210 --> 00:50:28,190 kilometers per hour so you're 1148 00:50:34,210 --> 00:50:31,220 multiplying by a buyout by large novella 1149 00:50:37,000 --> 00:50:34,220 by large numbers 3600 in order to get 1150 00:50:38,530 --> 00:50:37,010 these things up to per hour right rare 1151 00:50:40,300 --> 00:50:38,540 very large numbers in terms of per hour 1152 00:50:41,740 --> 00:50:40,310 but a couple thousand kilometers per 1153 00:50:44,859 --> 00:50:41,750 second which is how astronomers think of 1154 00:50:47,440 --> 00:50:44,869 it right okay well thank you Frank this 1155 00:50:49,089 --> 00:50:47,450 has been awesome I will I'm going to 1156 00:50:52,100 --> 00:50:49,099 stop it there but I want to remind 1157 00:50:54,320 --> 00:50:52,110 everybody that we can you 1158 00:50:57,380 --> 00:50:54,330 we have a new Hubble public lecture next 1159 00:50:59,300 --> 00:50:57,390 week and we will be broadcasting it on 1160 00:51:00,560 --> 00:50:59,310 YouTube I also wanted to point out I 1161 00:51:02,660 --> 00:51:00,570 should have done this at the top of the 1162 00:51:06,020 --> 00:51:02,670 Hangout but I didn't do it next on 1163 00:51:09,740 --> 00:51:06,030 Monday the ISA the European Space Agency 1164 00:51:12,620 --> 00:51:09,750 is launching a video contest called ode 1165 00:51:16,280 --> 00:51:12,630 to Hubble for Hubble's 25th and and I'm 1166 00:51:19,730 --> 00:51:16,290 gonna post it right now on the event 1167 00:51:22,580 --> 00:51:19,740 page i just posted it the link to where 1168 00:51:25,790 --> 00:51:22,590 you can learn more about it so if you 1169 00:51:27,320 --> 00:51:25,800 have a and they're taking all video 1170 00:51:29,660 --> 00:51:27,330 submissions i think under three minutes 1171 00:51:32,420 --> 00:51:29,670 so if you have something about Hubble 1172 00:51:34,520 --> 00:51:32,430 you'd like to say or a message you want 1173 00:51:38,180 --> 00:51:34,530 to send Hubble than they will you can 1174 00:51:39,680 --> 00:51:38,190 enter the contest and felt I think 1175 00:51:41,090 --> 00:51:39,690 they're going to they're going to 1176 00:51:42,620 --> 00:51:41,100 discuss what the prices are going to be 1177 00:51:44,930 --> 00:51:42,630 on my question what they are yet but 1178 00:51:46,580 --> 00:51:44,940 keep an eye out on that web page for it 1179 00:51:48,530 --> 00:51:46,590 and make a video make it into three 1180 00:51:50,330 --> 00:51:48,540 minutes and submitted and who knows what 1181 00:51:52,070 --> 00:51:50,340 will happen and
