Narrator: The sun. It has

3
00:00:22,100 --> 00:00:26,120
shed light on our home for over 4 billion years.

4
00:00:26,140 --> 00:00:30,160
It will continue to do so for another 4.

5
00:00:30,180 --> 00:00:34,180
It is massive almost

6
00:00:34,200 --> 00:00:38,210
beyond comprehension.

7
00:00:38,230 --> 00:00:42,240
Constant, yet ever changing.

8
00:00:42,260 --> 00:00:46,270
Born from a swirling

9
00:00:46,290 --> 00:00:50,310
cloud of dust and gas, it is a giant fusion engine

10
00:00:50,330 --> 00:00:54,350
that drives the solar system.

11
00:00:54,370 --> 00:00:58,400
It seethes and boils like a living thing.

12
00:00:58,420 --> 00:01:02,440
Loops of plasma rise up, so large

13
00:01:02,460 --> 00:01:06,490
they would dwarf Earth.

14
00:01:06,510 --> 00:01:10,510
Explosions flash on its surface.

-Music-

16
00:01:18,560 --> 00:01:22,570
And yet the sun also gives us warmth.

17
00:01:22,590 --> 00:01:26,590
And life.

18
00:01:26,610 --> 00:01:30,620
-Music-

19
00:01:30,640 --> 00:01:34,640
And beauty.
