1
00:00:00,083 --> 00:00:02,635
[Chelsea Gohd] Jupiter is
at its biggest and brightest,

2
00:00:03,069 --> 00:00:05,488
the Moon and Saturn
share the sky,

3
00:00:05,638 --> 00:00:08,058
and the Beehive Cluster
makes an appearance.

4
00:00:08,575 --> 00:00:11,177
That's What's Up, this January.

5
00:00:11,177 --> 00:00:12,379
January 10th,

6
00:00:12,379 --> 00:00:15,982
Jupiter will be at its most
brilliant of the entire year!

7
00:00:16,549 --> 00:00:20,153
This night, Jupiter will be at
what's called "opposition,"

8
00:00:20,336 --> 00:00:23,440
meaning that Earth
will be directly between

9
00:00:23,440 --> 00:00:25,041
Jupiter and the Sun.

10
00:00:25,041 --> 00:00:27,777
In this alignment,
Jupiter will appear bigger

11
00:00:27,777 --> 00:00:31,581
and brighter in the night sky
than it will all year.

12
00:00:31,798 --> 00:00:34,317
Talk about starting off
the new year bright!

13
00:00:34,317 --> 00:00:36,686
To see Jupiter at
its best this year,

14
00:00:36,686 --> 00:00:39,689
look to the east
and all evening long,

15
00:00:39,689 --> 00:00:42,842
you'll be able to see the planet
in the constellation Gemini.

16
00:00:43,143 --> 00:00:46,129
It will be one of the brightest
objects in the night sky.

17
00:00:46,312 --> 00:00:48,832
(only the Moon
and Venus will be brighter)

18
00:00:50,366 --> 00:00:51,718
Saturn and the Moon will

19
00:00:51,718 --> 00:00:55,705
share the sky on January 23rd
as part of a conjunction!

20
00:00:56,039 --> 00:00:59,042
A conjunction happens
when objects in the night sky

21
00:00:59,042 --> 00:01:02,779
look close together even though
they're actually far apart.

22
00:01:03,379 --> 00:01:06,382
To spot the pair,
look to the west and you'll see

23
00:01:06,382 --> 00:01:10,470
Saturn just below the Moon,
sparkling in the night sky.

24
00:01:11,571 --> 00:01:13,556
The Beehive Cluster
will be visible

25
00:01:13,556 --> 00:01:16,559
in the night sky
throughout January!

26
00:01:16,559 --> 00:01:17,844
The Beehive Cluster,

27
00:01:17,844 --> 00:01:20,480
more formally known
as Messier 44,

28
00:01:20,480 --> 00:01:21,931
or M44,

29
00:01:21,931 --> 00:01:24,601
is made of at least 1,000 stars.

30
00:01:24,834 --> 00:01:26,853
It's an open star cluster,

31
00:01:26,853 --> 00:01:29,906
meaning it's a
loosely-bound group of stars.

32
00:01:30,657 --> 00:01:33,143
There are thousands
of open star clusters

33
00:01:33,143 --> 00:01:35,662
like the Beehive
in the Milky Way Galaxy!

34
00:01:36,112 --> 00:01:39,299
To see the Beehive Cluster,
look to the eastern night sky

35
00:01:39,332 --> 00:01:43,019
just after sunset and before
midnight throughout the month.

36
00:01:43,586 --> 00:01:46,473
Especially great nights to spot
the cluster are around

37
00:01:46,473 --> 00:01:47,907
the middle of January

38
00:01:47,907 --> 00:01:51,711
when the cluster isn't too high
or too low in the sky to see.

39
00:01:51,961 --> 00:01:53,163
With dark skies

40
00:01:53,163 --> 00:01:55,949
you might be able to spot
the Beehive with just your eyes,

41
00:01:55,949 --> 00:01:59,252
but binoculars
or a small telescope will help.

42
00:02:00,653 --> 00:02:03,289
Here are the phases
of the Moon for January.

43
00:02:03,773 --> 00:02:06,259
You can stay up to date
on all of NASA's missions

44
00:02:06,259 --> 00:02:10,380
exploring the solar system
and beyond at science.nasa.gov.

45
00:02:11,548 --> 00:02:14,634
I'm Chelsea Gohd from NASA's Jet
Propulsion Laboratory,

46
00:02:14,818 --> 00:02:16,870
and that's
What's Up for this month.
