00:00:00,334 --> 00:00:04,004
Here's what you need to know
about ocean worlds.

2
00:00:06,640 --> 00:00:10,244
Earth is not the only world
in our solar system with an ocean.

3
00:00:10,677 --> 00:00:14,047
Oceans worlds exist in diverse forms

4
00:00:14,081 --> 00:00:15,148
on planets,

5
00:00:15,182 --> 00:00:16,416
dwarf planets,

6
00:00:16,450 --> 00:00:18,719
and even moons.

7
00:00:18,752 --> 00:00:21,021
Let's dive in and take a deeper look.

8
00:00:22,189 --> 00:00:24,725
Jupiter's moon, Europa,

9
00:00:25,459 --> 00:00:31,732
has a vast subsurface ocean
hidden beneath its icy crust.

10
00:00:31,765 --> 00:00:34,501
Saturn's moon, Enceladus,

11
00:00:34,535 --> 00:00:36,937
has a buried global ocean

12
00:00:36,970 --> 00:00:38,605
with geysers that spew its contents out

13
00:00:38,639 --> 00:00:41,441
hundreds of miles into space.

14
00:00:41,475 --> 00:00:44,678
Dwarf planet Ceres

15
00:00:44,711 --> 00:00:47,915
is believed to consist of about 25% water,

16
00:00:47,948 --> 00:00:51,151
some of which could be liquid.

17
00:00:51,185 --> 00:00:54,721
Jupiter's moon, Ganymede,

18
00:00:55,856 --> 00:01:00,561
could have several layers of ice and water
sandwiched between its crust and core.

19
00:01:00,594 --> 00:01:03,730
Dwarf planet Pluto

20
00:01:03,764 --> 00:01:07,100
could be home to buried oceans

21
00:01:07,134 --> 00:01:09,770
that slosh around far beneath
its frozen surface.

22
00:01:09,803 --> 00:01:11,338
Saturn's moon, Titan,

23
00:01:11,371 --> 00:01:13,974
is home to bizarre methane lakes
scattered across its exterior.

24
00:01:14,007 --> 00:01:16,143
But below the surface you'll find

25
00:01:16,176 --> 00:01:18,779
this mammoth moon
contains a liquid water ocean

26
00:01:18,812 --> 00:01:23,150
as salty as the Dead Sea on Earth.

27
00:01:23,183 --> 00:01:26,553
Neptune's far away moon, Triton,

28
00:01:26,587 --> 00:01:30,057
is predicted to hide an ocean deep beneath
its cantaloupe-like terrain.

29
00:01:30,090 --> 00:01:33,260
So why are ocean worlds so fascinating?

30
00:01:34,661 --> 00:01:38,098
They offer clues in the quest to discover
life beyond our home planet.

31
00:01:38,765 --> 00:01:41,335
Because where there is water,

32
00:01:41,368 --> 00:01:44,004
there is the potential for life.

33
00:01:44,037 --> 00:01:49,109
And that's what you need to know
about ocean worlds.
