1
00:00:05,829 --> 00:00:08,897
The Milky Way galaxy...
2
00:00:08,932 --> 00:00:13,735
a vast cosmic city
of 200 billion stars.
3
00:00:15,572 --> 00:00:17,940
We live in a quiet neighborhood,
4
00:00:17,974 --> 00:00:22,911
tucked away in a safe neck
of the woods.
5
00:00:22,946 --> 00:00:27,916
But what if we could take our planet
on a journey across the galaxy?
6
00:00:29,886 --> 00:00:34,223
From the violent graveyards
where stars, billions of years old,
7
00:00:34,257 --> 00:00:36,625
go to die...
8
00:00:41,998 --> 00:00:46,902
to the cosmic cradles
where new stars burst to life.
9
00:00:49,239 --> 00:00:54,209
Dare to travel through
billions of years of space and time
10
00:00:54,244 --> 00:00:58,147
to find out how our galaxy
came to be...
11
00:00:59,315 --> 00:01:02,818
and the dark fate that awaits us.
12
00:01:02,852 --> 00:01:06,922
It's the ultimate journey
to uncover the secrets that lie...
13
00:01:06,956 --> 00:01:09,925
inside the Milky Way.
14
00:01:23,473 --> 00:01:25,507
Modern cities are a testament
15
00:01:25,542 --> 00:01:30,379
to some of the greatest accomplishments
of human civilization-
16
00:01:30,413 --> 00:01:35,851
feats of engineering that dazzle
with millions of lights.
17
00:01:35,885 --> 00:01:40,355
But the bright lights conceal
something even more amazing.
18
00:01:43,159 --> 00:01:49,097
Turn them off and behold...
a great city in the sky.
19
00:01:52,335 --> 00:01:56,872
What is this?
Well, this is the Milky Way.
20
00:01:56,906 --> 00:01:59,274
This is our galaxy.
21
00:01:59,309 --> 00:02:03,545
Well, if you'd like, you could think
of the galaxy as a city of stars.
22
00:02:08,184 --> 00:02:12,020
Our sun is just one
of the 200 billion stars
23
00:02:12,055 --> 00:02:15,657
that make up a vast cosmic city.
24
00:02:21,097 --> 00:02:25,734
A city we're just beginning to know.
25
00:02:25,768 --> 00:02:28,704
It's really a wonderful time
to be an astronomer,
26
00:02:28,738 --> 00:02:30,706
especially in studies
of the Milky Way.
27
00:02:30,740 --> 00:02:32,975
We're undergoing something
of a revolution.
28
00:02:33,009 --> 00:02:37,980
In fact we can take you places
that are really quite remarkable.
29
00:02:38,014 --> 00:02:41,350
We're about
to make a major move.
30
00:02:43,720 --> 00:02:45,287
We're picking up the earth
31
00:02:45,321 --> 00:02:48,257
and traveling across
thousands of light years-
32
00:02:48,291 --> 00:02:52,227
relocating to distant neighborhoods
of the galaxy.
33
00:02:54,130 --> 00:02:57,332
From our new address
the sky looks different...
34
00:02:57,367 --> 00:02:59,635
full of wonder and beauty...
35
00:02:59,669 --> 00:03:03,538
lit by a multitude of brilliant suns...
36
00:03:15,018 --> 00:03:20,255
...revealing the power of stars
that lived billions of years ago.
37
00:03:22,859 --> 00:03:29,865
Out here we'll get a glimpse of the future,
when our sun exists no more.
38
00:03:32,535 --> 00:03:38,006
It's a journey to unravel some
of the greatest mysteries of the universe:
39
00:03:39,609 --> 00:03:42,344
how the Milky Way was born,
40
00:03:42,378 --> 00:03:45,213
how it survived for so long
41
00:03:45,248 --> 00:03:48,150
and how it will eventually die.
42
00:04:00,963 --> 00:04:04,032
But before our trip can begin,
43
00:04:04,067 --> 00:04:06,968
we need a map
of where we're headed.
44
00:04:09,005 --> 00:04:11,406
And making one is the job
of astronomers
45
00:04:11,441 --> 00:04:15,510
like Robert Kirshner
and James Bullock.
46
00:04:21,551 --> 00:04:27,723
The first obstacle is simply figuring out
what kind of galaxy the Milky Way is.
47
00:04:29,192 --> 00:04:31,093
The Hubble Space Telescope
48
00:04:31,127 --> 00:04:36,798
gives astronomers the capability
to see billions of other galaxies.
49
00:04:36,833 --> 00:04:38,934
Each one is different.
50
00:04:38,968 --> 00:04:43,105
But it turns out there is a pattern.
51
00:04:43,139 --> 00:04:46,408
When we look out to study
other galaxies in the universe,
52
00:04:46,442 --> 00:04:50,946
We see that there are basically
two types of galaxies.
53
00:04:50,980 --> 00:04:54,049
The first type,
elliptical galaxies,
54
00:04:54,083 --> 00:04:58,787
appear as large balls of stars,
55
00:04:58,821 --> 00:05:01,523
and no matter what angle
they're viewed from,
56
00:05:01,557 --> 00:05:04,760
they always look rounded.
57
00:05:06,963 --> 00:05:13,135
The other main class is
the so-called "spiral galaxies,"
58
00:05:13,169 --> 00:05:19,741
because their stars are contained in arms
that spiral out from their centers.
59
00:05:22,645 --> 00:05:28,116
From a distance, a spiral galaxy
looks something like a Frisbee.
60
00:05:30,620 --> 00:05:34,022
The key to correctly
identifying the Milky Way
61
00:05:34,056 --> 00:05:37,359
is written across our night sky.
62
00:05:43,299 --> 00:05:48,103
The Milky Way,
we believe, is a spiral galaxy.
63
00:05:48,137 --> 00:05:49,304
So what we're really seeing,
64
00:05:49,338 --> 00:05:51,473
when we look up at night at this band,
65
00:05:51,507 --> 00:05:53,475
is we're seeing our place
in the universe.
66
00:05:53,509 --> 00:05:57,512
We're part of a giant disc of stars.
67
00:05:57,547 --> 00:06:01,416
But that's just
an insider's view.
68
00:06:05,655 --> 00:06:09,558
Now, of course I can't show you
a picture of the galaxy in all its glory.
69
00:06:09,592 --> 00:06:13,995
We can't fly above the galaxy
and take a picture of it and show you.
70
00:06:14,030 --> 00:06:16,164
We're stuck in the disc of the galaxy,
71
00:06:16,199 --> 00:06:18,300
but we can still image it
from the ground.
72
00:06:18,334 --> 00:06:22,304
In fact, this image is a picture
of our galaxy, the Milky Way,
73
00:06:22,338 --> 00:06:23,839
taken from Earth.
74
00:06:26,476 --> 00:06:28,810
This is one
of the most detailed images
75
00:06:28,845 --> 00:06:31,713
of our galaxy ever created.
76
00:06:33,583 --> 00:06:36,651
It's made from 800 million pixels
77
00:06:36,686 --> 00:06:40,789
contained in over a thousand
individual photographs,
78
00:06:40,823 --> 00:06:44,426
taken from the darkest
places on Earth.
79
00:06:47,630 --> 00:06:50,499
The photos have been painstakingly
stitched together
80
00:06:50,533 --> 00:06:54,536
to create this breathtaking view.
81
00:07:01,477 --> 00:07:06,815
But impressive as it is,
it's only part of the picture.
82
00:07:08,150 --> 00:07:09,417
It's something like a pizza.
83
00:07:09,452 --> 00:07:11,953
And if you were in the pizza,
if you were a pepperoni,
84
00:07:11,988 --> 00:07:16,491
your view would not be a very clear one
of what the whole story was.
85
00:07:16,526 --> 00:07:21,096
In the same way, we don't see
the whole reach of the Milky Way.
86
00:07:21,130 --> 00:07:26,535
What astronomers
really need is a bird's eye view.
87
00:07:26,569 --> 00:07:27,936
You would need
to get out of the Milky Way
88
00:07:27,970 --> 00:07:30,338
to really see what it looks like.
89
00:07:30,373 --> 00:07:32,140
We don't have a way to do that,
90
00:07:32,174 --> 00:07:36,444
but we can look at other galaxies
and see what they look like.
91
00:07:40,182 --> 00:07:44,953
Hubble's cameras capture
nearby galaxies in amazing detail-
92
00:07:44,987 --> 00:07:48,290
like Messier 74.
93
00:07:48,324 --> 00:07:51,626
Although it's over 30 million
light years away,
94
00:07:51,661 --> 00:07:54,863
it's one of our closest neighbors.
95
00:07:58,568 --> 00:08:04,306
Messier 74 is
a beautiful spiral galaxy.
96
00:08:04,340 --> 00:08:09,311
Its large, starry arms sweep out
from a bright core.
97
00:08:13,382 --> 00:08:15,250
This is an example
of a galaxy
98
00:08:15,284 --> 00:08:18,787
that astronomers think looks
a lot like our galaxy, the Milky Way.
99
00:08:18,821 --> 00:08:23,291
This is a great representation
of our own star city.
100
00:08:23,326 --> 00:08:26,227
In the central region
we have the downtown.

away,9400:07:51,661 --> 00:07:54,863it's one of our closest neighbors.9500:07:58,568 --> 00:08:04,306Messier 74 isa beautiful spiral galaxy.9600:08:04,340 --> 00:08:09,311Its large, starry arms sweep
