1 00:00:08,780 --> 00:00:06,260 ever wonder how astronomers get those 2 00:00:11,299 --> 00:00:08,790 amazing pictures from space telescopes 3 00:00:15,340 --> 00:00:11,309 it's not quite as simple as pulling out 4 00:00:18,380 --> 00:00:15,350 a camera and snapping a Kodak moment as 5 00:00:20,599 --> 00:00:18,390 the visualization scientist for NASA's 6 00:00:23,269 --> 00:00:20,609 Spitzer Space Telescope and Galaxy 7 00:00:25,099 --> 00:00:23,279 Evolution Explorer dr. Robert hurt 8 00:00:28,099 --> 00:00:25,109 translates the information from 9 00:00:31,250 --> 00:00:28,109 spacecraft into extraordinary images 10 00:00:33,830 --> 00:00:31,260 that help us understand the cosmos well 11 00:00:35,840 --> 00:00:33,840 what we generally do is we'll start with 12 00:00:37,069 --> 00:00:35,850 the core of the sciences that look at 13 00:00:39,410 --> 00:00:37,079 the data will look at the published 14 00:00:41,450 --> 00:00:39,420 paper that tells what the astronomers 15 00:00:43,639 --> 00:00:41,460 discover and then what we want to do is 16 00:00:45,580 --> 00:00:43,649 get into that negative result that thing 17 00:00:48,619 --> 00:00:45,590 that we're trying to teach the public 18 00:00:50,900 --> 00:00:48,629 NASA Spitzer Space Telescope observes 19 00:00:54,979 --> 00:00:50,910 infrared light the Galaxy Evolution 20 00:00:56,660 --> 00:00:54,989 Explorer studies ultraviolet light when 21 00:00:58,639 --> 00:00:56,670 the spacecraft sends us an image it's 22 00:01:01,069 --> 00:00:58,649 actually just a bunch of numbers it's 23 00:01:03,650 --> 00:01:01,079 it's numbers that capture how bright 24 00:01:05,539 --> 00:01:03,660 each part of the sky is at a particular 25 00:01:08,750 --> 00:01:05,549 wavelength of light one that we can't 26 00:01:11,570 --> 00:01:08,760 see hurt is an astronomer and an artist 27 00:01:14,660 --> 00:01:11,580 he uses his computer to ship things that 28 00:01:17,030 --> 00:01:14,670 are invisible to our eyes and makes them 29 00:01:20,300 --> 00:01:17,040 visible so what I have to do is take 30 00:01:22,580 --> 00:01:20,310 this data which effectively counts as as 31 00:01:24,800 --> 00:01:22,590 black-and-white images that come through 32 00:01:26,870 --> 00:01:24,810 colored filters on the tall scope and 33 00:01:29,749 --> 00:01:26,880 what we have to do this take these these 34 00:01:31,700 --> 00:01:29,759 colors at the I can't see and assign 35 00:01:33,920 --> 00:01:31,710 them in two colors that the eye can see 36 00:01:36,890 --> 00:01:33,930 and when we do that we can build up what 37 00:01:40,399 --> 00:01:36,900 we call a representative color image red 38 00:01:43,160 --> 00:01:40,409 shows heat from hot dust blue show star 39 00:01:46,539 --> 00:01:43,170 light which is even hotter and green the 40 00:01:48,710 --> 00:01:46,549 fluorescent light of organic molecules 41 00:01:52,190 --> 00:01:48,720 suddenly we see things around the 42 00:01:54,350 --> 00:01:52,200 universe that we'd never seen before but 43 00:01:56,270 --> 00:01:54,360 what if the story doesn't have a picture 44 00:01:58,760 --> 00:01:56,280 that was the case with a galaxy 45 00:02:01,940 --> 00:01:58,770 discovery that showed black holes stifle 46 00:02:04,249 --> 00:02:01,950 the formation of new stars sometimes we 47 00:02:06,740 --> 00:02:04,259 end up with with science stories they're 48 00:02:09,050 --> 00:02:06,750 actually extremely difficult to tell 49 00:02:11,300 --> 00:02:09,060 just from the data what's a 50 00:02:13,790 --> 00:02:11,310 visualization artists to do 51 00:02:16,490 --> 00:02:13,800 literally have to go back to the drawing 52 00:02:19,400 --> 00:02:16,500 board to tell the story hurts colleague 53 00:02:21,770 --> 00:02:19,410 Tim pile created this artist concept of 54 00:02:23,300 --> 00:02:21,780 a black hole we wouldn't claim that 55 00:02:25,820 --> 00:02:23,310 these things that we have visualized in 56 00:02:27,680 --> 00:02:25,830 our artists conceptions are exactly what 57 00:02:30,140 --> 00:02:27,690 these things look like because literally 58 00:02:32,690 --> 00:02:30,150 we don't know but what we can do is get 59 00:02:35,059 --> 00:02:32,700 as close as we understand today a 60 00:02:37,850 --> 00:02:35,069 spitzer study uncovered evidence of 61 00:02:39,740 --> 00:02:37,860 planet Earth around a dead star though 62 00:02:43,400 --> 00:02:39,750 you'd hardly know it by looking at a 63 00:02:47,120 --> 00:02:43,410 graph so hurt creating an animation of a 64 00:02:49,820 --> 00:02:47,130 star that dies in a fiery blast and the 65 00:02:52,820 --> 00:02:49,830 aftermath it has to tell the story in an 66 00:02:54,920 --> 00:02:52,830 exciting way but also has to be true to 67 00:02:58,059 --> 00:02:54,930 the science has to be realistic armed 68 00:03:00,559 --> 00:02:58,069 with science creativity and inspiration 69 00:03:03,289 --> 00:03:00,569 visualization scientists and artists are 70 00:03:06,470 --> 00:03:03,299 taking us to distant reaches of the 71 00:03:08,900 --> 00:03:06,480 universe we've done visualizations to 72 00:03:11,539 --> 00:03:08,910 show planets around other stars you've 73 00:03:14,059 --> 00:03:11,549 shown but sunsets would look like in 74 00:03:15,440 --> 00:03:14,069 exotic systems astronomers today are 75 00:03:17,990 --> 00:03:15,450 solving some the most interesting 76 00:03:22,069 --> 00:03:18,000 mysteries in the history of mankind and 77 00:03:24,500 --> 00:03:22,079 if we can visually make that exciting to
