HUBBLE CAPTURES
GIANT PLANETS

2
00:00:04.326 --> 00:00:14.632
In 1977, the twin spacecraft Voyager 1 and Voyager 2
left the Earth for their bold mission of discovery.

3
00:00:14.632 --> 00:00:30.000
“The Grand Tour” program gave humanity
its first close-up view of the outer planets...

4
00:00:30.000 --> 00:00:42.294
Jupiter
Its Great Red Spot is a storm
that’s been churning for centuries.

5
00:00:42.294 --> 00:00:52.483
Saturn
Its rings are made of particles as
small as sand to as big as a house.

6
00:00:52.483 --> 00:01:04.347
Uranus
It’s the only planet that
rotates on its side.

7
00:01:04.347 --> 00:01:15.464
Neptune
Its winds blow as fast as
1.300 miles per hour.

8
00:01:15.464 --> 00:01:25.888
Four decades later, the Hubble Space Telescope
is working on a “grand tour” of its own.

9
00:01:25.888 --> 00:01:41.614
Hubble’s Outer Planets Atmospheres
Legacy program is looking closely at
these gas giants every year.

10
00:01:41.614 --> 00:01:55.347
Hubble's yearly observations track subtle changes
in their atmospheres over a regular time period...

11
00:01:55.347 --> 00:02:04.872
...giving us a better understanding of how they evolve.

12
00:02:04.872 --> 00:02:17.276
Even at nearly 3 billion miles from the outer planets,
Hubble captured their images in great detail…

13
00:02:17.276 --> 00:02:25.361
…enough to see variations in their atmospheres.

14
00:02:25.361 --> 00:02:39.094
JUPITER
Hubble’s 2021 images of Jupiter track the
ever-changing landscape of its turbulent atmosphere,
where several new storms are making their mark.

15
00:02:39.094 --> 00:02:50.944
SATURN
This new look at Saturn shows rapid
and extreme color changes in the bands
of the planet’s northern hemisphere.

16
00:02:50.944 --> 00:03:02.019
URANUS
The increase in ultraviolet radiation
absorbed from the Sun seems to be
causing the polar region to brighten.

17
00:03:02.019 --> 00:03:13.980
NEPTUNE
A storm discovered on Neptune in 2018 has reversed
direction and is moving north. This new “dark spot” is visible
in this image, along with a darkened northern hemisphere.

18
00:03:13.980 --> 00:03:27.733
Thanks to Hubble’s watchful eye, these gas giants
will continue to provide us with clues to their evolution.
