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.
