| NARRATOR:
Hundreds of billions of stars
in our galaxy. |
00:00:07.040 - 00:00:11.377 |
| And yet we know of only one
that shines |
00:00:11.444 - 00:00:14.213 |
| on a life-filled planet. |
00:00:14.280 - 00:00:18.050 |
| Is Earth unique? |
00:00:18.118 - 00:00:19.918 |
| Or are there other solar systems
and planets like ours... |
00:00:19.986 - 00:00:24.089 |
| out there? |
00:00:24.157 - 00:00:25.457 |
| Now, scientists are finding
the answer. |
00:00:28.428 - 00:00:32.431 |
| Thanks to this: |
00:00:32.499 - 00:00:37.002 |
| The Kepler Space Telescope. |
00:00:37.070 - 00:00:39.405 |
| The most powerful planet hunter
ever built. |
00:00:39.472 - 00:00:41.573 |
| It's making astonishing
discoveries. |
00:00:45.512 - 00:00:48.647 |
| NATALIE BATALHA:
The sheer numbers of planets
out there |
00:00:48.715 - 00:00:50.883 |
| is really quite stupendous. |
00:00:50.950 - 00:00:51.984 |
| NARRATOR:
From enormous gas giants... |
00:00:54.020 - 00:00:58.057 |
| to a land where the sun
never sets... |
00:00:58.124 - 00:01:01.326 |
| to worlds that may be entirely
covered in water. |
00:01:01.394 - 00:01:06.432 |
| Kepler is even finding planets
like our own. |
00:01:06.499 - 00:01:10.936 |
| GEOFF MARCY:
This might be the first
Earth analogue |
00:01:11.004 - 00:01:13.505 |
| around a sun-like star
that's ever been found. |
00:01:13.573 - 00:01:16.408 |
| NARRATOR:
Scientists are beginning
to wonder if those planets |
00:01:19.979 - 00:01:22.748 |
| could be inhabited. |
00:01:22.816 - 00:01:25.784 |
