What's Up for October?

3
00:00:04,454 --> 00:00:07,490
Some great Moon
and planet pairings,

4
00:00:07,490 --> 00:00:10,076
a mission to a metal rich world,

5
00:00:10,076 --> 00:00:12,812
and a partial
eclipse of the Sun.

6
00:00:12,896 --> 00:00:16,700
On October 2nd, the Moon rises
a couple of hours after sunset,

7
00:00:16,700 --> 00:00:20,403
appearing super close
to the Pleiades star cluster.

8
00:00:20,487 --> 00:00:24,491
Look for them low in the east
after around 10 p.m..

9
00:00:24,574 --> 00:00:27,160
They travel across the sky
together that night, leaving

10
00:00:27,160 --> 00:00:30,146
another opportunity to see them
the following morning.

11
00:00:30,397 --> 00:00:32,365
In the predawn
sky on October 3rd,

12
00:00:32,365 --> 00:00:34,401
the Moon appears
a couple of finger-widths

13
00:00:34,401 --> 00:00:35,802
apart from the Pleiades,

14
00:00:35,802 --> 00:00:38,805
having moved a bit in its orbit
around Earth during the night.

15
00:00:38,988 --> 00:00:42,008
Look for them high in the
southwest, flanked by Jupiter

16
00:00:42,008 --> 00:00:46,196
and the bright, red giant star
Aldebaran in Taurus.

17
00:00:46,279 --> 00:00:48,932
On October 10th,
look for Venus in the east

18
00:00:48,932 --> 00:00:53,119
before sunrise, accompanied
by a slim crescent Moon.

19
00:00:53,203 --> 00:00:55,071
And in between them,
the bright heart of Leo

20
00:00:55,071 --> 00:00:58,408
the lion, bluish-white
star Regulus.

21
00:00:58,491 --> 00:01:01,061
On October 23rd,
look toward the south, an hour

22
00:01:01,061 --> 00:01:04,330
or two after sunset
to find the Moon, about 70%

23
00:01:04,330 --> 00:01:07,934
illuminated, hanging
just beneath the planet Saturn.

24
00:01:08,017 --> 00:01:10,670
Their close proximity in the sky
will make for some easy

25
00:01:10,670 --> 00:01:14,157
telescope viewing of these
two skywatching favorites.

26
00:01:14,240 --> 00:01:16,543
The following evening,
the Moon will still be nearby,

27
00:01:16,543 --> 00:01:19,028
having moved
to the east of Saturn.

28
00:01:19,028 --> 00:01:20,146
The full moon on

29
00:01:20,146 --> 00:01:23,900
October 28th rises
together with planet Jupiter.

30
00:01:23,983 --> 00:01:25,018
These are two of the brightest

31
00:01:25,018 --> 00:01:27,320
objects in the sky,
and seeing them so close

32
00:01:27,320 --> 00:01:30,623
should make
for quite an impressive sight.

33
00:01:30,707 --> 00:01:32,408
When you gaze up at Venus

34
00:01:32,408 --> 00:01:33,860
or Mars, Mercury

35
00:01:33,860 --> 00:01:35,945
(or even an Earth
beneath your feet),

36
00:01:35,945 --> 00:01:39,999
do you ever wonder how these
planets formed out of stardust?

37
00:01:40,083 --> 00:01:42,268
That's how planetary
scientists think, too.

38
00:01:42,268 --> 00:01:43,436
And this month, NASA's

39
00:01:43,436 --> 00:01:45,722
launching a spacecraft
to seek insights into

40
00:01:45,722 --> 00:01:48,308
how the “terrestrial”
planets developed.

41
00:01:48,308 --> 00:01:51,494
NASA's Psyche spacecraft
is planned to launch in October

42
00:01:51,494 --> 00:01:55,048
on its multi-year journey
to an asteroid of the same name.

43
00:01:55,131 --> 00:01:57,684
It's the first mission
to a metal-rich asteroid,

44
00:01:57,684 --> 00:02:00,670
which could be part of
the interior of a planetesimal,

45
00:02:00,804 --> 00:02:03,123
a building
block of a rocky planet.

46
00:02:03,123 --> 00:02:04,941
Asteroid Psyche
could also turn out

47
00:02:04,941 --> 00:02:06,860
to be a different kind
of iron rich object

48
00:02:06,860 --> 00:02:08,678
that's not been seen before.

49
00:02:08,678 --> 00:02:10,713
Whatever its story
turns out to be,

50
00:02:10,713 --> 00:02:12,482
it's hoped
the mission might show us

51
00:02:12,482 --> 00:02:14,467
how Earth's core
and the course of other

52
00:02:14,467 --> 00:02:17,720
terrestrial planets came to be.

53
00:02:17,804 --> 00:02:20,657
On October 14th,
skywatchers in the Americas

54
00:02:20,657 --> 00:02:23,076
will have an opportunity
to see a special type

55
00:02:23,076 --> 00:02:26,396
of solar eclipse
called an annular eclipse.

56
00:02:26,479 --> 00:02:29,549
Along a path about 125
miles wide,

57
00:02:29,566 --> 00:02:31,401
the Sun will appear as a narrow

58
00:02:31,401 --> 00:02:35,071
ring of light, which is often
called a “ring of fire.”

59
00:02:35,155 --> 00:02:38,575
This narrow circle shape
is also known as an annulus,

60
00:02:38,608 --> 00:02:41,494
giving this type of eclipse
its name.

61
00:02:41,494 --> 00:02:44,197
Solar eclipses happen
when the Moon comes between

62
00:02:44,197 --> 00:02:45,698
Earth and the Sun and covers

63
00:02:45,698 --> 00:02:47,967
at least part of
the Sun in the sky.

64
00:02:47,967 --> 00:02:49,652
When the Moon covers
the Sun completely,

65
00:02:49,652 --> 00:02:52,172
we get to observe
a total eclipse.

66
00:02:52,172 --> 00:02:54,941
But sometimes the Moon is a bit
farther away in its orbit

67
00:02:54,941 --> 00:02:56,593
when an eclipse happens,
making it

68
00:02:56,593 --> 00:02:58,294
look a little smaller in the sky

69
00:02:58,294 --> 00:03:01,598
and just a bit too small
to completely cover the Sun.

70
00:03:01,681 --> 00:03:05,435
When that happens, it enables us
to see an annular eclipse.

71
00:03:05,518 --> 00:03:08,721
The path of this partial eclipse
sweeps across the Americas,

72
00:03:08,721 --> 00:03:11,925
beginning in Southern Canada
and crossing the Western U.S.,

73
00:03:11,925 --> 00:03:15,111
before moving across
Central and South America.

74
00:03:15,195 --> 00:03:18,164
Outside the annular eclipse
path, those within the viewing

75
00:03:18,164 --> 00:03:20,617
zone will still see
a partial eclipse.

76
00:03:20,617 --> 00:03:22,569
The maximum amount of the Sun
that will be covered

77
00:03:22,569 --> 00:03:24,921
by the Moon
depends on your location.

78
00:03:24,921 --> 00:03:28,458
Now, eclipse fans won't have to
wait long for more excitement.

79
00:03:28,541 --> 00:03:31,411
Next April, a total
solar eclipse will sweep

80
00:03:31,411 --> 00:03:33,213
across the U.S..

81
00:03:33,213 --> 00:03:35,999
Check out NASA's eclipse
resources online for info

82
00:03:35,999 --> 00:03:38,318
about both eclipses,
where they'll be visible,

83
00:03:38,318 --> 00:03:39,769
and tips for safe viewing.

84
00:03:41,404 --> 00:03:41,888
Here are the

85
00:03:41,888 --> 00:03:43,957
phases of the Moon for October.

86
00:03:45,758 --> 00:03:47,827

and beyond at nasa.gov.

Jet Propulsion Laboratory,
