it was so unusual we were a little unsure 140 00:04:44,339 --> 00:04:44,349 was so unusual we were a little unsure 141 00:04:44,349 --> 00:04:46,770 was so unusual we were a little unsure just what we were dealing with so I 142 00:04:46,770 --> 00:04:46,780 just what we were dealing with so I 143 00:04:46,780 --> 00:04:49,999 just what we were dealing with so I started to scan it and Jupiter was a big 144 00:04:49,999 --> 00:04:50,009 started to scan it and Jupiter was a big 145 00:04:50,009 --> 00:04:53,820 started to scan it and Jupiter was a big overexposed looking blob on one side I 146

170 00:05:28,560 --> 00:05:28,570 said I don't know what I've got it looks 171 00:05:28,570 --> 00:05:31,800 said I don't know what I've got it looks like a squashed comet the squashed comet 172 00:05:31,800 --> 00:05:31,810 like a squashed comet the squashed comet 173 00:05:31,810 --> 00:05:34,170 like a squashed comet the squashed comet turned out to be a chain of fragments 174 00:05:34,170

194 00:06:00,809 --> 00:06:00,819 we thought the largest fragments might 195 00:06:00,819 --> 00:06:02,520 we thought the largest fragments might be about three maybe even four 196 00:06:02,520 --> 00:06:02,530 be about three maybe even four 197 00:06:02,530 --> 00:06:06,270 be about three maybe even four kilometers across about two and a up to 198 00:06:06,270 --> 00:06:06,280 kilometers across about two and a up to 199 00:06:06,280 --> 00:06:08,850 kilometers across about two and a up to two and a half miles in diameter if they 200 00:06:08,850 --> 00:06:08,860 two and a half miles in diameter if they 201 00:06:08,860 --> 00:06:12,540 two and a half miles in diameter if they were that large then altogether these 202 00:06:12,540 --> 00:06:12,550 were that large then altogether these 203 00:06:12,550 --> 00:06:15,360 were that large then altogether these comets would deliver about a hundred 204 00:06:15,360 --> 00:06:15,370 comets would deliver about a hundred 205 00:06:15,370 --> 00:06:19,619 comets would deliver about a hundred million megatons of energy but no one is 206 00:06:19,619 --> 00:06:19,629 million megatons of energy but no one is 207 00:06:19,629 --> 00:06:21,749 million megatons of energy but no one is quite sure what effect the impacts will 208 00:06:21,749 --> 00:06:21,759 quite sure what effect the impacts will 209 00:06:21,759 --> 00:06:24,420 quite sure what effect the impacts will have on the planet an immense globe of 210 00:06:24,420 --> 00:06:24,430 have on the planet an immense globe of 211 00:06:24,430 --> 00:06:27,029 have on the planet an immense globe of gas a thousand times larger than the 212 00:06:27,029 --> 00:06:27,039 gas a thousand times larger than the 213 00:06:27,039 --> 00:06:27,709 gas a thousand times larger than the earth 214 00:06:27,709 --> 00:06:27,719 earth 215 00:06:27,719 --> 00:06:30,450 earth Timothy Dowling and Joe Harrington of 216 00:06:30,450 --> 00:06:30,460 Timothy Dowling and

00:06:32,080 --> 00:06:34,350 the Massachusetts Institute of Technology have developed a computer 220 00:06:34,350 --> 00:06:34,360 Technology have developed a computer 221 00:06:34,360 --> 00:06:36,269 Technology have developed a computer model that shows the effect of the 222 00:06:36,269 --> 00:06:36,279 model that shows the effect of the 223 00:06:36,279 --> 00:06:38,929 model that shows the effect of the Comets impact on Jupiter's atmosphere 224 00:06:38,929 --> 00:06:38,939 Comets impact on Jupiter's atmosphere 225 00:06:38,939 --> 00:06:41,670 Comets impact on Jupiter's atmosphere the comet pieces will plunge down 226 00:06:41,670 --> 00:06:41,680 the comet pieces will plunge down 227 00:06:41,680 --> 00:06:43,469 the comet pieces will plunge down underneath the clouds these beautiful 228 00:06:43,469 --> 00:06:43,479 underneath the clouds these beautiful 229 00:06:43,479 --> 00:06:45,300 underneath the clouds these beautiful ammonia clouds that are on the surface 230 00:06:45,300 --> 00:06:45,310 ammonia clouds that are on the surface 231 00:06:45,310 --> 00:06:47,640 ammonia clouds that are on the surface and finally just give up and explode and 232 00:06:47,640 --> 00:06:47,650 and finally just give up and explode and 233 00:06:47,650 --> 00:06:50,070 and finally just give up and explode and all of that hot heated gas will rise up 234 00:06:50,070 --> 00:06:50,080 all of that hot heated gas will rise up 235 00:06:50,080 --> 00:06:51,930 all of that hot heated gas will rise up and then it'll fall back down and you'll 236 00:06:51,930 --> 00:06:51,940 and then it'll fall back down and you'll 237 00:06:51,940 --> 00:06:53,399 and then it'll fall back down and you'll get just like throwing a rock into a 238 00:06:53,399 --> 00:06:53,409 get just like throwing a rock into a 239 00:06:53,409 --> 00:06:55,230 get just like throwing a rock into a pond you won't get this big splash and 240 00:06:55,230 --> 00:06:55,240 pond you won't get this big splash and 241 00:06:55,240 --> 00:06:57,839 pond you won't get this big splash and then the slower ripple during the six 242 00:06:57,839 --> 00:06:57,849 then the slower

images it will 262 00:07:26,219 --> 00:07:26,229 eventually sending back images it will 263 00:07:26,229 --> 00:07:28,740 eventually sending back images it will be an unprecedented opportunity to learn 264 00:07:28,740 --> 00:07:28,750 be an unprecedented opportunity to learn 265 00:07:28,750 --> 00:07:31,060 be an unprecedented opportunity to learn about the planets weather patterns 266 00:07:31,060 --> 00:07:31,070 about the planets weather patterns 267 00:07:31,070 --> 00:07:33,580 about the planets weather patterns Joe Harrington believes the explosions 268 00:07:33,580 --> 00:07:33,590 Joe Harrington believes the explosions 269 00:07:33,590 --> 00:07:36,190 Joe Harrington believes the explosions could trigger storm systems in normally 270 00:07:36,190 --> 00:07:36,200 could trigger storm systems in normally 271 00:07:36,200 --> 00:07:38,590 could trigger storm systems in normally stable areas if the pieces are big 272 00:07:38,590 --> 00:07:38,600 stable areas if the pieces are big 273 00:07:38,600 --> 00:07:40,900 stable areas if the pieces are big enough to produce any kind of observable 274 00:07:40,900 --> 00:07:40,910 enough to produce any kind of observable 275 00:07:40,910 --> 00:07:42,250 enough to produce any kind of observable effect at all anything that makes the 276 00:07:42,250 --> 00:07:42,260 effect at all anything that makes the 277 00:07:42,260 --> 00:07:43,420 effect at all anything that makes the planet look different from the way it 278 00:07:43,420 --> 00:07:43,430 planet look different from the way it 279 00:07:43,430 --> 00:07:44,170 planet look different from the way it looks today 280 00:07:44,170 --> 00:07:44,180 looks today 281 00:07:44,180 --> 00:07:45,760 looks today will learn something and the more 282 00:07:45,760 --> 00:07:45,770 will learn something and the more 283 00:07:45,770 --> 00:07:47,920 will learn something and the more changes the more we'll learn in fact 284 00:07:47,920 --> 00:07:47,930 changes the more we'll learn in fact 285 00:07:47,930 --> 00:07:50,350 changes the more we'll learn in fact there are valuable lessons in store for 286 00:07:50,350 --> 00:07:50,360 there are valuable lessons in store for 287 00:07:50,360 --> 00:07:52,420 there are valuable lessons in store for our own planet there are a lot of people 288 00:07:52,420 --> 00:07:52,430 our own planet there are a lot of people 289 00:07:52,430 --> 00:07:54,610 our own planet there are a lot of people that believe that an impact about the 290 00:07:54,610 --> 00:07:54,620 that believe that an impact about the 291 00:07:54,620 --> 00:07:57,400 that believe that an impact about the size of the combined comet train is what 292 00:07:57,400 --> 00:07:57,410 size of the combined comet train is what 293 00:07:57,410 --> 00:07:59,800 size of the combined comet train is what killed off the dinosaurs gene shoemaker 294 00:07:59,800 --> 00:07:59,810 killed off the dinosaurs gene shoemaker 295 00:07:59,810 --> 00:08:02,560 killed off the dinosaurs gene shoemaker has long supported the theory that comet 296 00:08:02,560 --> 00:08:02,570 has long supported the theory that comet 297 00:08:02,570 --> 00:08:05,620 has long supported the theory that comet material landed some 4.5 billion years 298 00:08:05,620 --> 00:08:05,630 material landed some 4.5 billion years 299 00:08:05,630 --> 00:08:07,840 material landed some 4.5 billion years ago and delivered life's essential 300 00:08:07,840 --> 00:08:07,850 ago and delivered life's essential 301 00:08:07,850 --> 00:08:10,300 ago and delivered life's essential ingredients to earth in essence I think 302 00:08:10,300 --> 00:08:10,310 ingredients to earth in essence I think 303 00:08:10,310 --> 00:08:13,530 ingredients to earth in essence I think we're the progeny of comet's comets 304 00:08:13,530 --> 00:08:13,540 we're the progeny of comet's comets 305 00:08:13,540 --> 00:08:15,790 we're the progeny of comet's comets arriving early in the history of the 306 00:08:15,790 --> 00:08:15,800 arriving early in the history of the 307 00:08:15,800 --> 00:08:19,120 arriving early in the history of the solar system delivered the volatile 308 00:08:19,120 --> 00:08:19,130 solar system delivered the volatile 309 00:08:19,130 --> 00:08:22,900 solar system delivered the volatile material come july 16 damager and 310 00:08:22,900 --> 00:08:22,910 material come july 16 damager and 311 00:08:22,910 --> 00:08:25,030 material come july 16 damager and professional astronomers alike will 312 00:08:25,030 --> 00:08:25,040 professional astronomers alike will 313 00:08:25,040 --> 00:08:27,310 professional astronomers alike will train their telescopes on jupiter 314 00:08:27,310 --> 00:08:27,320 train their telescopes on jupiter 315 00:08:27,320 --> 00:08:29,590 train their telescopes on jupiter whether the event goes off with a bang 316 00:08:29,590 --> 00:08:29,600 whether the event goes off with a bang 317 00:08:29,600 --> 00:08:33,370 whether the event goes off with a bang or a whimper few astronomers will miss 318 00:08:33,370 --> 00:08:33,380 or a whimper few astronomers will miss 319 00:08:33,380 --> 00:13:17,519 or a whimper few astronomers will miss this cosmic event of a lifetime 320 00:13:17,519 --> 00:13:17,529 321 00:13:17,529 --> 00:13:20,220 we knew he had something very unusual it 322 00:13:20,220 --> 00:13:20,230 we knew he had something very unusual it 323 00:13:20,230 --> 00:13:22,500 we knew he had something very unusual it was so unusual we were a little unsure 324 00:13:22,500 --> 00:13:22,510 was so unusual we were a little unsure 325 00:13:22,510 --> 00:13:24,389 was so unusual we were a little unsure just what we were dealing with 326 00:13:24,389 --> 00:13:24,399 just what we were dealing with 327 00:13:24,399 --> 00:13:27,030 just what we were dealing with we were pretty stacked up and when I 328 00:13:27,030 --> 00:13:27,040 we were pretty stacked up and when I 329 00:13:27,040 --> 00:13:29,490 we were pretty stacked up and when I looked at it I realized that what I saw 330 00:13:29,490 --> 00:13:29,500 looked at it I realized that what I saw 331 00:13:29,500 --> 00:13:33,900 looked at it I realized that what I saw was a bar and this bar had coma and 332 00:13:33,900 --> 00:13:33,910 was a bar and this bar had coma and 333 00:13:33,910 --> 00:13:38,879 was a bar and this bar had coma and Tails and I that was um it's unspeakably 334 00:13:38,879 --> 00:13:38,889 Tails and I that was um it's unspeakably 335 00:13:38,889 --> 00:13:41,790 Tails and I that was um it's unspeakably weird you just don't find something like 336 00:13:41,790 --> 00:13:41,800 weird you just don't find something like 337 00:13:41,800 --> 00:13:43,829 weird you just don't find something like that when you're looking for either 338 00:13:43,829 --> 00:13:43,839 that when you're looking for either 339 00:13:43,839 --> 00:13:47,460 that when you're looking for either asteroids or comets and nothing no yes 340 00:13:47,460 --> 00:13:47,470 asteroids or comets and nothing no yes 341 00:13:47,470 --> 00:13:49,980 asteroids or comets and nothing no yes but comet pieces will plunge down 342 00:13:49,980 --> 00:13:49,990 but comet pieces will plunge down 343 00:13:49,990 --> 00:13:51,720 but comet pieces will plunge down underneath the clouds these beautiful 344 00:13:51,720 --> 00:13:51,730 underneath the clouds these beautiful 345 00:13:51,730 --> 00:13:53,400 underneath the clouds these beautiful ammonia clouds that are on the surface 346 00:13:53,400 --> 00:13:53,410 ammonia clouds that are on the surface 347 00:13:53,410 --> 00:13:55,829 ammonia clouds that are on the surface plunge down underneath and finally just 348 00:13:55,829 --> 00:13:55,839 plunge down underneath and finally just 349 00:13:55,839 --> 00:13:58,079 plunge down underneath and finally just give up and explode and all of that hot 350 00:13:58,079 --> 00:13:58,089 give up and explode and all of that hot 351 00:13:58,089 --> 00:14:00,210 give up and explode and all of that hot heated gas will rise up and then it'll 352 00:14:00,210 --> 00:14:00,220 heated gas will rise up and then it'll 353 00:14:00,220 --> 00:14:02,009 heated gas will rise up and then it'll fall back down and you'll get just like 354 00:14:02,009 --> 00:14:02,019 fall back down and you'll get just like 355 00:14:02,019 --> 00:14:03,210 fall back down and you'll get just like throwing a rock into a pond you won't 356 00:14:03,210 --> 00:14:03,220 throwing a rock into a pond you won't 357 00:14:03,220 --> 00:14:05,280 throwing a rock into a pond you won't get this big splash and then the slower 358 00:14:05,280 --> 00:14:05,290 get this big splash and then the slower 359 00:14:05,290 --> 00:14:07,740 get this big splash and then the slower Ripple
