00:00:01.860 --> 00:00:04.860
laughs

3
00:00:05.339 --> 00:00:08.160
constellations

4
00:00:08.160 --> 00:00:11.820
there are more than 300 billion stars in

5
00:00:11.820 --> 00:00:13.740
the Milky Way galaxy

6
00:00:13.740 --> 00:00:16.260
the Milky Way is the Galaxy where our

7
00:00:16.260 --> 00:00:18.239
solar system is located

8
00:00:18.239 --> 00:00:21.000
our solar system is made up of space

9
00:00:21.000 --> 00:00:23.100
rocks planets

10
00:00:23.100 --> 00:00:28.080
the Sun the moon and of course Earth

11
00:00:28.080 --> 00:00:30.900
but did you know that the Milky Way is

12
00:00:30.900 --> 00:00:33.120
only one of about a hundred billion

13
00:00:33.120 --> 00:00:34.500
galaxies

14
00:00:34.500 --> 00:00:36.840
and if we put all of those billions of

15
00:00:36.840 --> 00:00:38.940
galaxies together there would be

16
00:00:38.940 --> 00:00:41.040
trillions and trillions of stars

17
00:00:41.040 --> 00:00:43.680
throughout the universe that's a lot of

18
00:00:43.680 --> 00:00:44.840
stars

19
00:00:44.840 --> 00:00:47.879
amazingly out of all those trillions of

20
00:00:47.879 --> 00:00:50.820
stars when you look up at the sky you

21
00:00:50.820 --> 00:00:54.180
can only see about 4 500 of them you

22
00:00:54.180 --> 00:00:56.820
were only seeing a tiny fraction of how

23
00:00:56.820 --> 00:00:59.579
many stars are really out there

24
00:00:59.579 --> 00:01:02.160
what's remarkable is that out of the

25
00:01:02.160 --> 00:01:05.339
trillions of stars each one is different

26
00:01:05.339 --> 00:01:07.680
some Stars may have their own system of

27
00:01:07.680 --> 00:01:11.220
planets some stars are older than others

28
00:01:11.220 --> 00:01:14.819
and some Stars May no longer exist but

29
00:01:14.819 --> 00:01:17.819
their light still travels toward Earth

30
00:01:17.819 --> 00:01:20.400
that may seem odd that a star's light

31
00:01:20.400 --> 00:01:22.860
can still be seen after it's gone

32
00:01:22.860 --> 00:01:26.400
but Stars Are Born they live and after

33
00:01:26.400 --> 00:01:29.938
some time they die just like us

34
00:01:29.938 --> 00:01:33.000
after they die their light continues to

35
00:01:33.000 --> 00:01:35.700
travel throughout the Universe by the

36
00:01:35.700 --> 00:01:38.340
time its Light reaches us a star might

37
00:01:38.340 --> 00:01:40.140
have been dead for thousands of years

38
00:01:40.140 --> 00:01:41.520
already

39
00:01:41.520 --> 00:01:44.578
there are people who study space

40
00:01:44.578 --> 00:01:47.579
Mars and the universe for their job

41
00:01:47.579 --> 00:01:50.820
these people are called astronomers

42
00:01:50.820 --> 00:01:53.579
the earliest astronomers noticed that

43
00:01:53.579 --> 00:01:55.680
many of the brightest stars in our

44
00:01:55.680 --> 00:01:58.799
galaxy formed pictures in the sky

45
00:01:58.799 --> 00:02:02.100
they call these pictures constellations

46
00:02:02.100 --> 00:02:05.579
similar to connect the dots pictures

47
00:02:05.579 --> 00:02:07.979
when the twinkling stars are connected

48
00:02:07.979 --> 00:02:10.679
they form a constellation the

49
00:02:10.679 --> 00:02:13.580
constellations make up shapes of people

50
00:02:13.580 --> 00:02:17.280
animals and mythological beings

51
00:02:17.280 --> 00:02:19.800
the word mythological comes from the

52
00:02:19.800 --> 00:02:20.940
word myth

53
00:02:20.940 --> 00:02:24.540
a myth is a made-up Story the Greeks and

54
00:02:24.540 --> 00:02:28.319
Romans made up stories about Gods Heroes

55
00:02:28.319 --> 00:02:31.739
and creatures such as serpents dragons

56
00:02:31.739 --> 00:02:34.200
or flying horses

57
00:02:34.200 --> 00:02:36.480
they then named various constellations

58
00:02:36.480 --> 00:02:37.860
after them

59
00:02:37.860 --> 00:02:40.379
let's take a closer look at a few

60
00:02:40.379 --> 00:02:42.780
constellations that might be familiar to

61
00:02:42.780 --> 00:02:43.739
you

62
00:02:43.739 --> 00:02:46.620
as you look at these constellations you

63
00:02:46.620 --> 00:02:48.540
may notice that some of them are easier

64
00:02:48.540 --> 00:02:50.480
to see than others

65
00:02:50.480 --> 00:02:53.459
sometimes the images are just a series

66
00:02:53.459 --> 00:02:55.739
of straight lines in a special pattern

67
00:02:55.739 --> 00:02:57.860
that may not look exactly like a person

68
00:02:57.860 --> 00:03:01.620
animal or mythological being

69
00:03:01.620 --> 00:03:04.620
many of the constellations require you

70
00:03:04.620 --> 00:03:07.620
to use your imagination to see the image

71
00:03:07.620 --> 00:03:09.480
they create

72
00:03:09.480 --> 00:03:12.180
see if you recognize any of these

73
00:03:12.180 --> 00:03:14.540
constellations

said to be very very brave

80
00:03:31.919 --> 00:03:34.379
this constellation is an image of

81
00:03:34.379 --> 00:03:37.260
Hercules who became a God after his

82
00:03:37.260 --> 00:03:39.120
death

83
00:03:39.120 --> 00:03:42.659
Orion mainly consists of supergiant

84
00:03:42.659 --> 00:03:44.940
stars which are the largest and

85
00:03:44.940 --> 00:03:46.500
brightest stars

86
00:03:46.500 --> 00:03:49.319
three of these stars form a line called

87
00:03:49.319 --> 00:03:53.459
Orion's Belt they lead to sirius which

88
00:03:53.459 --> 00:03:56.099
is the brightest star in the sky

and a very good Hunter

Zeus placed him Among the Stars after

94
00:04:10.319 --> 00:04:12.000
Orion's death

95
00:04:12.000 --> 00:04:14.640
Orion looks like he is defending himself

96
00:04:14.640 --> 00:04:17.238
from a nearby constellation called

97
00:04:17.238 --> 00:04:19.500
Taurus the Bull

hand and a lion pelt in the other

00:04:26.279 --> 00:04:29.460
this constellation is visible throughout

101
00:04:29.460 --> 00:04:31.800
the world

102
00:04:31.800 --> 00:04:34.620

that his Hooves dug out a spring and

107
00:04:46.500 --> 00:04:49.020
anyone who drank the water was given the

153
00:06:47.160 --> 00:06:49.500
the Big Dipper is not actually a

154
00:06:49.500 --> 00:06:52.380
constellation as some people think it is

155
00:06:52.380 --> 00:06:55.319
called an asterism which is a group of

156
00:06:55.319 --> 00:06:57.720
stars that are smaller than a

157
00:06:57.720 --> 00:07:00.419

158
00:07:00.419 --> 00:07:01.740

Aquarius and Pisces

195
00:08:29.699 --> 00:08:33.000
constellations can be very useful they

196
00:08:33.000 --> 00:08:35.458
have helped ancient Farmers know when to

197
00:08:35.458 --> 00:08:38.039
plant and harvest crops and they were

198
00:08:38.039 --> 00:08:40.979
used as a type of calendar in the sky

199
00:08:40.979 --> 00:08:44.159
many Travelers relied on different stars

200
00:08:44.159 --> 00:08:48.120
like Polaris or the North Star as well

201
00:08:48.120 --> 00:08:51.420
as various constellations to guide them

00:08:51.420 --> 00:08:53.399
through their Journeys

203
00:08:53.399 --> 00:08:57.059
today modern astronomers and stargazers

204
00:08:57.059 --> 00:09:00.179
use constellations to help keep track of

205
00:09:00.179 --> 00:09:03.300
specific stars in the sky they are also

206
00:09:03.300 --> 00:09:06.000
used to locate other objects in the sky

207
00:09:06.000 --> 00:09:08.100
such as galaxies

208
00:09:08.100 --> 00:09:12.720
in 1922 the sky was divided into 88

209
00:09:12.720 --> 00:09:15.480
different constellations but not all of

210
00:09:15.480 --> 00:09:17.880
them are as well known as others

211
00:09:17.880 --> 00:09:21.059
many of the constellations may be seen

212
00:09:21.059 --> 00:09:23.640
in the northern hemisphere but may not

213
00:09:23.640 --> 00:09:26.220
be visible in the southern hemisphere

214
00:09:26.220 --> 00:09:29.279
and some may be easier to locate

215
00:09:29.279 --> 00:09:32.220
