1 00:00:00,000 --> 00:00:04,471 We are now in a new era of computing technology. 2 00:00:04,471 --> 00:00:09,142 We see artificial intelligence in nearly all aspects of our lives, 3 00:00:09,142 --> 00:00:11,911 from helping doctors and diagnosing diseases, 4 00:00:11,911 --> 00:00:15,348 to creating recipes based on what's in your pantry. 5 00:00:15,348 --> 00:00:18,752 AI is quickly changing the way we live. 6 00:00:18,752 --> 00:00:23,723 Artificial intelligence is also changing the way astronomers analyze data. 7 00:00:23,723 --> 00:00:27,961 Such advances have been used to increase the discoveries made by NASA's 8 00:00:27,961 --> 00:00:31,297 Hubble Space Telescope and in turn, Hubble's 9 00:00:31,297 --> 00:00:36,002 data has been used to advance and test artificial intelligence systems. 10 00:00:36,002 --> 00:00:40,240 Such systems were critical in discovering asteroids in Hubble data. 11 00:00:40,240 --> 00:00:44,377 To date, astronomers have found over a million asteroids in the main 12 00:00:44,377 --> 00:00:48,815 asteroid belt, an area between the orbits of Mars and Jupiter. 13 00:00:48,815 --> 00:00:54,087 But many smaller asteroids may not have been discovered because they are so faint. 14 00:00:54,087 --> 00:00:57,757 They are about 1/40,000,000 the brightness of the faintest 15 00:00:57,757 --> 00:01:00,560 star a human eye can see. 16 00:01:00,560 --> 00:01:03,563 This is where Hubble and AI come in. 17 00:01:03,563 --> 00:01:07,634 Hubble's archive contains over 1 million observations. 18 00:01:07,634 --> 00:01:11,471 Many of these smaller asteroids may be found in the images 19 00:01:11,471 --> 00:01:13,573 because they are moving across the skies 20 00:01:13,573 --> 00:01:16,776 as Hubble's view holds steady on an astronomical object. 21 00:01:16,776 --> 00:01:20,480 They appear as curved streaks of light in Hubble's cameras, 22 00:01:20,480 --> 00:01:23,383 essentially photobombing the image. 23 00:01:23,383 --> 00:01:26,619 Astronomers applied machine learning algorithms, 24 00:01:26,619 --> 00:01:32,792 a form of artificial intelligence, to hunt for these trails in over 37,000 images. 25 00:01:32,792 --> 00:01:36,062 That exercise was conducted with the help of 11,000 26 00:01:36,062 --> 00:01:41,101 citizen scientists, who discovered 1701 asteroids, 27 00:01:41,101 --> 00:01:46,573 1031 of these were small bodied asteroids not formerly known to exist. 28 00:01:46,573 --> 00:01:48,475 The results help provide insight 29 00:01:48,475 --> 00:01:52,479 into both the origin and evolution of the asteroid belt. 30 00:01:52,479 --> 00:01:57,517 AI can also revolutionize the way astronomers classify galaxies. 31 00:01:57,517 --> 00:02:01,254 Traditionally, astronomers would classify them by hand 32 00:02:01,254 --> 00:02:03,790 spirals, ellipticals, irregulars, 33 00:02:03,790 --> 00:02:07,460 and so on, a time consuming process. 34 00:02:07,460 --> 00:02:11,331 To test AI concepts, Hubble data has been used in studies 35 00:02:11,331 --> 00:02:15,168 on deep learning techniques, which use artificial neural network 36 00:02:15,168 --> 00:02:21,407 technologies to learn complex patterns and features from large data sets. 37 00:02:21,407 --> 00:02:26,012 In this case, the Hubble Candels data set that contains over 10,000 38 00:02:26,012 --> 00:02:30,950 classified galaxies and required dozens of astronomers time to classify, 39 00:02:30,950 --> 00:02:36,422 was used to teach a deep learning system about galaxy structure and forms. 40 00:02:36,422 --> 00:02:39,125 They then applied it to the Hubble Legacy field, 41 00:02:39,125 --> 00:02:43,596 a combination of nearly 7500 separate Hubble exposures, 42 00:02:43,863 --> 00:02:46,733 representing 16 years of observations 43 00:02:46,733 --> 00:02:51,171 that contained over 265,000 galaxies. 44 00:02:51,171 --> 00:02:56,209 With deep learning, AI can sort such a field at an incredible speed. 45 00:02:56,209 --> 00:02:59,179 This ability becomes even more important when NASA's 46 00:02:59,179 --> 00:03:03,049 Nancy Grace Roman Space Telescope images become available. 47 00:03:03,049 --> 00:03:07,987 Each of those images has over 100 times the field of view as Hubble. 48 00:03:07,987 --> 00:03:11,191 Similarly, Hubble data has been used to help test 49 00:03:11,191 --> 00:03:14,460 machine learning concepts to accommodate noisy data. 50 00:03:15,528 --> 00:03:17,530 Telescope imperfections or dust 51 00:03:17,530 --> 00:03:22,168 clouds can create flaws in images from even the best observatories. 52 00:03:22,168 --> 00:03:23,603 The machine learning systems 53 00:03:23,603 --> 00:03:27,774 can identify the noise and reconstruct the image accordingly. 54 00:03:27,774 --> 00:03:32,545 Noisy Hubble Galaxy images were used to test these concepts. 55 00:03:32,545 --> 00:03:35,548 Future telescopes like the Roman Space Telescope, 56 00:03:35,548 --> 00:03:38,251 will collect more data than ever before. 57 00:03:38,251 --> 00:03:44,357 Roman itself will likely amass 20,000TB of data over its five year mission. 58 00:03:44,357 --> 00:03:49,262 AI will be critical in processing such vast streams of information. 59 00:03:49,262 --> 00:03:54,734 From finding exoplanets to uncovering new clues about dark matter and dark energy. 60 00:03:54,734 --> 00:03:57,203 The next frontier of space exploration 61 00:03:57,203 --> 00:04:01,140 will not only depend on our instruments, but also on powerful software. 62 00:04:01,140 --> 00:04:02,609 Here on Earth. 63 00:04:02,609 --> 00:04:06,913 And Hubble data is helping with this new revolution. 64 00:04:06,913 --> 00:04:09,649 The fusion of Hubble's vast archive of data 65 00:04:09,649 --> 00:04:14,254 with cutting edge AI marks a new era in space exploration. 66 00:04:14,254 --> 00:04:19,158 The vast potential of machine learning can process unimaginable amounts of data, 67 00:04:19,158 --> 00:04:21,794 unlocking discoveries faster than before 68 00:04:21,794 --> 00:04:25,164 and recovering details we would otherwise have missed. 69 00:04:25,164 --> 00:04:29,569 The future of astronomy isn't just up in the stars, it's in the code. 70
