00:00:00,000 --> 00:00:06,129
The giant planet Jupiter, in all its banded
glory, takes the spotlight in these new images

2
00:00:06,129 --> 00:00:11,800
from NASA's Hubble Space Telescope that capture
both sides of the planet.

3
00:00:11,800 --> 00:00:18,650
Big enough to swallow Earth, the classic Great
Red Spot storm stands out prominently in Jupiter’s

4
00:00:18,650 --> 00:00:19,650
atmosphere.

5
00:00:19,650 --> 00:00:25,590
To its lower right, at a more southerly latitude,
is a feature sometimes dubbed Red Spot Jr.

6
00:00:25,590 --> 00:00:32,110
This giant storm, called an anticyclone, was
the result of other storms merging in 1998

7
00:00:32,110 --> 00:00:36,720
and 2000, and it first appeared red in 2006.

8
00:00:36,720 --> 00:00:42,310
The source of its red color is unknown but
may involve a range of chemical compounds:

9
00:00:42,310 --> 00:00:46,070
sulfur, phosphorus, or organic material.

10
00:00:46,070 --> 00:00:51,320
Staying in their lanes, but moving in opposite
directions, Red Spot Jr. passes the Great

11
00:00:51,320 --> 00:00:54,140
Red Spot about every two years.

12
00:00:54,140 --> 00:00:58,250
Hubble also captured Jupiter's volcanic moon,
Io.

13
00:00:58,250 --> 00:01:03,161
Only slightly larger than Earth's moon, Io
is the most volcanically active body in the

14
00:01:03,161 --> 00:01:04,161
solar system.

15
00:01:04,161 --> 00:01:09,980
Hubble’s sensitivity to blue and violet
wavelengths clearly reveals interesting surface

16
00:01:09,980 --> 00:01:11,330
features.

17
00:01:11,330 --> 00:01:16,010
Hubble monitors Jupiter and the other outer
solar system planets every year under the

18
00:01:16,010 --> 00:01:20,750
Outer Planet Atmospheres Legacy program, or
OPAL.

19
00:01:20,750 --> 00:01:26,619
These large worlds are shrouded in clouds
and hazes stirred up by violent winds, causing

20
00:01:26,619 --> 00:01:31,460
a kaleidoscope of ever-changing weather patterns
for Hubble to investigate.

21
00:01:31,460 --> 00:01:36,290
Studying the planets in our solar system helps
us understand our own weather patterns closer

22
00:01:36,290 --> 00:01:42,600
to home, and allows us to theorize what potential
exoplanet weather is like in other star systems

23
00:01:42,600 --> 00:01:43,580
in our universe.
