WEBVTT FILE 1 00:00:00.000 --> 00:00:08.876 The Hubble Space Telescope celebrated its 30th birthday on April 24, 2020. 2 00:00:08.876 --> 00:00:23.912 To mark the occasion, it premiered this image of a giant red nebula (NGC 2014) and its smaller blue neighbor (NGC 2020). 3 00:00:23.912 --> 00:00:33.282 Both are part of a star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, located 163,000 light-years away. 4 00:00:33.282 --> 00:00:42.687 Hubble continues to reveal the mysteries of the cosmos. 5 00:00:42.687 --> 00:00:51.758 Here are some achievements from Hubble’s latest year in orbit. 6 00:00:51.758 --> 00:00:56.194 SOLAR SYSTEM 7 00:00:56.194 --> 00:01:07.232 Hubble captured detailed images of Jupiter, Uranus, Neptune, and Saturn. 8 00:01:07.232 --> 00:01:21.536 Hubble also captured images of the first confirmed interstellar comet to visit our solar system: Comet 2I/Borisov. 9 00:01:21.536 --> 00:01:30.305 Hubble identified regular table salt hiding in plain sight on the surface of Jupiter’s moon Europa. 10 00:01:30.305 --> 00:01:40.875 The salt could come from a subsurface ocean, which might be more like Earth’s oceans than once thought. 11 00:01:40.875 --> 00:01:46.478 EXOPLANETS 12 00:01:46.478 --> 00:01:58.449 Hubble detected water vapor in the atmosphere of an exoplanet in its star’s “habitable zone.” 13 00:01:58.449 --> 00:02:05.886 K2-18b is the only exoplanet known to have water in its atmosphere... 14 00:02:05.886 --> 00:02:11.588 ...and temperatures that could sustain liquid water if it is rocky. 15 00:02:11.588 --> 00:02:23.293 Hubble helped to uncover clues about the atmosphere and origins of exoplanet GJ 3470 b. 16 00:02:23.293 --> 00:02:28.297 Bigger than Earth but smaller than Neptune, this planet is unlike anything in our solar system... 17 00:02:28.297 --> 00:02:36.668 ...but planets like it are common elsewhere in the galaxy. 18 00:02:36.668 --> 00:02:43.306 EXTRAGALACTIC 19 00:02:43.306 --> 00:02:54.377 The Hubble Legacy Field combines 16 years of observations to trace the history of the universe. 20 00:02:54.377 --> 00:03:04.481 This vast portrait of the cosmos contains roughly 265,000 galaxies… 21 00:03:04.481 --> 00:03:17.286 ...stretching back 13.3 billion years through time. 22 00:03:17.286 --> 00:03:28.622 Astronomers used the telescope to refine the Hubble constant, tracking the universe’s growth. 23 00:03:28.622 --> 00:03:40.828 After 30 years, Hubble continues its mission of discovery, further uncovering the mysteries of the universe. 24 00:03:40.828 --> 00:04:12.165 [ INTENSE MUSIC ]
