1 00:00:06,950 --> 00:00:02,010 foreign 2 00:00:11,629 --> 00:00:09,290 this is an image of ADA Carino taken 3 00:00:14,209 --> 00:00:11,639 with the Hubble Space Telescope and 4 00:00:16,369 --> 00:00:14,219 there's a lot going on in this image if 5 00:00:18,529 --> 00:00:16,379 you go down into the very center of this 6 00:00:20,929 --> 00:00:18,539 image you can see this bright spot here 7 00:00:23,450 --> 00:00:20,939 that's actually two stars much much more 8 00:00:25,670 --> 00:00:23,460 massive than the Sun that are in orbit 9 00:00:29,570 --> 00:00:25,680 around one another so what you see here 10 00:00:33,350 --> 00:00:29,580 are these two lobes of material and they 11 00:00:36,770 --> 00:00:33,360 are from a giant eruption that this star 12 00:00:38,510 --> 00:00:36,780 had about 200 years ago and when these 13 00:00:40,970 --> 00:00:38,520 massive stars are near the ends of their 14 00:00:43,670 --> 00:00:40,980 life they become quite unstable and 15 00:00:46,310 --> 00:00:43,680 there was this a tremendous eruption 16 00:00:48,470 --> 00:00:46,320 that blew up about 20 times the mass of 17 00:00:50,330 --> 00:00:48,480 the Sun and there was a massive 18 00:00:52,430 --> 00:00:50,340 brightening of the star became one of 19 00:00:55,970 --> 00:00:52,440 the brightest stars in the sky in the 20 00:00:58,369 --> 00:00:55,980 1840s and what we see here is the result 21 00:01:01,430 --> 00:00:58,379 of that massive eruption and these lobes 22 00:01:04,009 --> 00:01:01,440 of material that are slowly making their 23 00:01:06,469 --> 00:01:04,019 way out into Interstellar space Mariners 24 00:01:08,690 --> 00:01:06,479 at the time used it as a navigation Aid 25 00:01:12,350 --> 00:01:08,700 this frightening only lasted a number of 26 00:01:14,149 --> 00:01:12,360 years and then it since faded but the 27 00:01:15,410 --> 00:01:14,159 adacrine is still a relatively bright 28 00:01:19,250 --> 00:01:15,420 star 29 00:01:21,230 --> 00:01:19,260 the dust in this homunculus nebula which 30 00:01:24,230 --> 00:01:21,240 is what it's called is going to continue 31 00:01:28,070 --> 00:01:24,240 to expand it's being illuminated by the 32 00:01:31,730 --> 00:01:30,109 here's another image of ADA Carina taken 33 00:01:34,010 --> 00:01:31,740 with Hubble it looks a little different 34 00:01:36,530 --> 00:01:34,020 Hubble Is outfitted with very 35 00:01:39,410 --> 00:01:36,540 specialized filters that can see the 36 00:01:41,870 --> 00:01:39,420 light emitted from specific atoms at 37 00:01:44,690 --> 00:01:41,880 specific wavelengths the blue shows you 38 00:01:47,810 --> 00:01:44,700 where the Magnesium is emitting light 39 00:01:49,969 --> 00:01:47,820 the red shows regions where nitrogen is 40 00:01:52,550 --> 00:01:49,979 emitting light they have different 41 00:01:55,370 --> 00:01:52,560 ionization States they respond to this 42 00:01:56,810 --> 00:01:55,380 ultraviolet light in different ways one 43 00:01:59,030 --> 00:01:56,820 of the things that happens in these 44 00:02:01,730 --> 00:01:59,040 massive stars is they're factories for 45 00:02:03,230 --> 00:02:01,740 heavier elements and that's where the 46 00:02:05,149 --> 00:02:03,240 heavy elements in our bodies and the 47 00:02:07,730 --> 00:02:05,159 Earth all come from stars like this 48 00:02:09,770 --> 00:02:07,740 supernovae and massive stars that 49 00:02:11,869 --> 00:02:09,780 process them and eject the material back 50 00:02:13,850 --> 00:02:11,879 out into space and that's sort of the 51 00:02:15,410 --> 00:02:13,860 hard work that astronomers want to do 52 00:02:17,990 --> 00:02:15,420 because we want to understand all the 53 00:02:20,570 --> 00:02:18,000 details of what's happening in this 54 00:02:24,770 --> 00:02:20,580 nebula that's what these extraordinary 55 00:02:27,170 --> 00:02:24,780 eyes that Hubble has allow us to do 56 00:02:29,330 --> 00:02:27,180 this is a very complex and volatile 57 00:02:32,449 --> 00:02:29,340 object and in fact one of the reasons 58 00:02:34,670 --> 00:02:32,459 for being interested is that on the list 59 00:02:37,729 --> 00:02:34,680 of stars that we know about in the Milky 60 00:02:40,070 --> 00:02:37,739 Way that may soon become supernovae this 61 00:02:42,470 --> 00:02:40,080 is one of them it takes about 8 000 62 00:02:45,050 --> 00:02:42,480 years for the light from Ada Karina to 63 00:02:47,630 --> 00:02:45,060 reach us and so it could already have
