WEBVTT FILE 1 00:00:01.360 --> 00:00:05.780 The Hubble Space Telescope celebrates its 29th birthday in April 2019. 2 00:00:07.020 --> 00:00:12.160 To mark the occasion, it premiered this image of the Southern Crab Nebula. 3 00:00:12.940 --> 00:00:18.180 The space telescope continues to reveal the mysteries of the cosmos. 4 00:00:19.080 --> 00:00:24.200 Here are some achievements from Hubble's latest year in orbit. 5 00:00:25.860 --> 00:00:29.760 SOLAR SYSTEM 6 00:00:31.260 --> 00:00:37.640 Hubble showed the seasonal dynamics in the atmospheres of Uranus and Neptune, 7 00:00:38.840 --> 00:00:44.980 viewed storms on Saturn and Mars during their closest approach to Earth, 8 00:00:46.700 --> 00:00:51.920 and spotted 'Oumuamua, the first known interstellar object to visit our solar system. 9 00:00:52.820 --> 00:00:58.300 Hubble caught the mysterious visitor having an unexpected change in speed. 10 00:00:59.760 --> 00:01:04.120 EXOPLANETS 11 00:01:05.920 --> 00:01:10.220 Hubble made discoveries about planets around other stars, 12 00:01:12.480 --> 00:01:16.720 from studying a gas giant with an atmosphere hot enough to melt silver, 13 00:01:18.540 --> 00:01:23.800 to detecting helium for the first time in an exoplanet's atmosphere, 14 00:01:24.400 --> 00:01:29.860 and helping find the first evidence for a possible moon outside our solar system. 15 00:01:30.920 --> 00:01:36.120 Hubble also found that young red dwarf stars have more intense flares than older red dwarfs. 16 00:01:37.020 --> 00:01:42.040 These superflares could endanger any planets forming around the red dwarfs. 17 00:01:43.840 --> 00:01:50.460 EXTRAGALACTIC 18 00:01:52.000 --> 00:01:57.040 Hubble premiered this ultra-HD view of the Triangulum Galaxy 19 00:01:57.760 --> 00:02:03.560 and found that star formation is 10 times more intense here than in the Andromeda Galaxy. 20 00:02:04.700 --> 00:02:10.400 Hubble finished the larges ultraviolet survey of nearby galaxies. 21 00:02:11.980 --> 00:02:16.340 More than 50 galaxies were surveyed to better understand star formation. 22 00:02:17.320 --> 00:02:23.460 Hubble used light from orphaned stars to trace the distribution of dark matter 23 00:02:24.200 --> 00:02:31.980 and studied merging black holes at the centers of colliding galaxies. 24 00:02:32.540 --> 00:02:39.440 The Hubble and Gaia telescopes refined the Hubble constant, tracking the universe's growth. 25 00:02:41.620 --> 00:02:45.800 To learn more about Hubble's continuing mission of discovery, visit...
