[Music]

2
00:00:08,950 --> 00:00:07,759
interstellar space is the space between

3
00:00:11,509 --> 00:00:08,960
the stars

4
00:00:13,749 --> 00:00:11,519
but that doesn't mean that all space is

5
00:00:15,190 --> 00:00:13,759
interstellar it's a bit more complicated

6
00:00:17,830 --> 00:00:15,200
than that

7
00:00:20,870 --> 00:00:17,840
at the center of the solar system is our

8
00:00:22,710 --> 00:00:20,880
very own star the sun

9
00:00:24,630 --> 00:00:22,720
that has eight planets orbiting around

10
00:00:26,870 --> 00:00:24,640
it including our own

11
00:00:29,349 --> 00:00:26,880
and the sun is also constantly spewing

12
00:00:31,750 --> 00:00:29,359
out a stream of high-energy particles

13
00:00:33,910 --> 00:00:31,760
which we call the solar wind

14
00:00:36,630 --> 00:00:33,920
this wind forms a giant bubble around

15
00:00:38,709 --> 00:00:36,640
our entire solar system other stars have

16
00:00:41,510 --> 00:00:38,719
similar shells around them

17
00:00:43,590 --> 00:00:41,520
interstellar space begins at the edge

18
00:00:47,670 --> 00:00:43,600
of those star bubbles

19
00:00:50,069 --> 00:00:47,680
which are much bigger than these bubbles

20
00:00:51,430 --> 00:00:50,079
interstellar space is hot and cold at

21
00:00:54,790 --> 00:00:51,440
the same time

22
00:00:57,189 --> 00:00:54,800
the particles are moving really fast

23
00:00:58,470 --> 00:00:57,199
fast moving particles means high

24
00:00:59,830 --> 00:00:58,480
temperatures

25
00:01:02,229 --> 00:00:59,840
but get this

26
00:01:05,350 --> 00:01:02,239
you can still freeze to death

27
00:01:08,310 --> 00:01:05,360
the particles are so spread out that

28
00:01:10,950 --> 00:01:08,320
they're not very good at transferring

29
00:01:13,750 --> 00:01:10,960
heat to your body

30
00:01:15,190 --> 00:01:13,760
inside the solar system all the wind

31
00:01:17,030 --> 00:01:15,200
comes from the sun

32
00:01:19,030 --> 00:01:17,040
and the sun's bubble actually blocks out

33
00:01:21,030 --> 00:01:19,040
the wind from other stars

34
00:01:22,950 --> 00:01:21,040
but out in interstellar space there's

35
00:01:25,030 --> 00:01:22,960
wind blowing from many different stars

36
00:01:27,350 --> 00:01:25,040
and it all swirls together it's a

37
00:01:30,069 --> 00:01:27,360
glorious mix of particles energy and

38
00:01:33,109 --> 00:01:30,079
magnetic fields totally unlike the kind

39
00:01:36,230 --> 00:01:33,119
of environment we experience on earth

40
00:01:38,390 --> 00:01:36,240
in the 1970s nasa launched two space

41
00:01:41,190 --> 00:01:38,400
probes that are now speeding through

42
00:01:43,030 --> 00:01:41,200
interstellar space beyond the bubble of

43
00:01:45,270 --> 00:01:43,040
our solar system

44
00:01:47,990 --> 00:01:45,280
after a tour of our neighbor planets

45
00:01:50,950 --> 00:01:48,000
voyager 1 and voyager 2

46
00:01:53,270 --> 00:01:50,960
are now the first human-made objects on

47
00:01:55,749 --> 00:01:53,280
an interstellar adventure

48
00:01:57,910 --> 00:01:55,759
another out of this world thing about

49
00:02:00,950 --> 00:01:57,920
interstellar space is that each of the

50
00:02:04,149 --> 00:02:00,960
voyagers is carrying a golden record on

51
00:02:06,709 --> 00:02:04,159
its journey with songs sounds and

52
00:02:09,510 --> 00:02:06,719
greetings from our home on planet earth

53
00:02:12,150 --> 00:02:09,520
so maybe one day they'll tell the story

54
00:02:14,150 --> 00:02:12,160
of our world to extraterrestrial

55
00:02:16,470 --> 00:02:14,160
it's pretty cool that we humans now have

56
00:02:18,630 --> 00:02:16,480
a message in a bottle all the way out

57
00:02:20,470 --> 00:02:18,640
there in interstellar space

58
00:02:23,190 --> 00:02:20,480
thanks for joining us with five things

59
00:02:25,350 --> 00:02:23,200
about interstellar space and tune in to
