00:00:29,460 --> 00:00:30,050

we're here to help you find your way
 
around the sky tonight because Halloween

8
00:00:34,030 --> 00:00:36,660
greeting cards often depict a witch

9
00:00:36,660 --> 00:00:41,160
riding a broom in front of a full moon
 
many people have the mistaken notion

10
00:00:41,160 --> 00:00:42,420
that there's a full moon

11
00:00:42,420 --> 00:00:46,760
every year at Halloween when in fact we
 
won't have a full moon on Halloween

12
00:00:46,760 --> 00:00:47,309
again

13
00:00:47,309 --> 00:00:51,140
until 2020 this Halloween the gibbous
 
moon

14
00:00:51,140 --> 00:00:55,500
will be trick-or-treating in the sky
 
with mars Jupiter and Mercury

15
00:00:55,500 --> 00:00:58,940
but they're is something you can see in
 
the night sky

16
00:00:58,940 --> 00:01:02,610
every Halloween that is even if tear and
 
definitely spookier

17
00:01:02,610 --> 00:01:05,930
because every Halloween the plea
 
eighties the Seven Sisters

18
00:01:05,930 --> 00:01:09,190
fly high across the sky that night let's
 
show you

19
00:01:09,190 --> 00:01:12,740
okay we're facing East before dawn

20
00:01:12,740 --> 00:01:16,720
and Jupiter and Mercury will be visible
 
Jupiter will be very bright

21
00:01:16,720 --> 00:01:20,539
and you can use the Big Dipper to are
 
tart terrace and then march

22
00:01:20,539 --> 00:01:26,209
onto mercury then look south west about
 
an hour after sunset Monday night the 27

23
00:01:26,209 --> 00:01:28,090
four days before Halloween

24
00:01:28,090 --> 00:01:31,140
first thing you'll notice is a young
 
crescent moon

25
00:01:31,140 --> 00:01:35,369
there's not enough time for the moon to
 
reach the four-phase before Halloween

26
00:01:35,369 --> 00:01:38,950
so no full moon for the which to fly
 
across this year

27
00:01:38,950 --> 00:01:43,050
just Simmons left you'll see the bright
 
reddish orange planet Mars

28
00:01:43,050 --> 00:01:47,470
marceau remain low in the southwest
 
evening sky for the rest of the year

29
00:01:47,470 --> 00:01:51,229
as earth leaves mars farther and farther
 
behind as we both

30
00:01:51,229 --> 00:01:55,380
orbit the Sun let's advance one day and
 
the moonwalk fatten up a bit

31
00:01:55,380 --> 00:02:00,190
and move above Mars on Tuesday evening
 
let's go one more day to wednesday

32
00:02:00,190 --> 00:02:01,050
evening

33
00:02:01,050 --> 00:02:04,130
the moon's a bit fatter and a bit
 
farther from mars

34
00:02:04,130 --> 00:02:08,190
Thursday night the moon is waxing more
 
and has moved farther

35
00:02:08,190 --> 00:02:12,060
East notice how much the moon moves from
 
one night to the next

36
00:02:12,060 --> 00:02:16,379
Friday night Halloween the moon is still
 
a long way from fall

37
00:02:16,379 --> 00:02:19,819
but they're is a hollow weenie object in
 
this evening sky

38
00:02:19,819 --> 00:02:25,480
let's turn and look northeast and a plea
 
eighties are just rising but wire the

39
00:02:25,480 --> 00:02:29,040
plea eighties and Halloween LinkedIn so
 
many people's minds

40
00:02:29,040 --> 00:02:32,220
let's quote Jack Horkheimer on this one

41
00:02:32,220 --> 00:02:37,170
too many people long ago when the please
 
reach their highest point at midnight

42
00:02:37,170 --> 00:02:40,690
it was a signal that this was the time
 
of the year two honor the debt

43
00:02:40,690 --> 00:02:45,050
many people's belief that a great inch
 
in Cataclysm occurred when the pleadings

44
00:02:45,050 --> 00:02:48,320
were overhead at midnight such as the
 
great biblical flood

45
00:02:48,320 --> 00:02:52,840
or the thinking about lantus the belief
 
was so widespread that in mexico

46
00:02:52,840 --> 00:02:57,570
the Pyramid of the Sun tayo t work was
 
built to align with the setting up the

47
00:02:57,570 --> 00:02:58,360
plea eighties

48
00:02:58,360 --> 00:03:02,380
as we're all the city's West running
 
streets an ancient Greece

49
00:03:02,380 --> 00:03:06,540
several temples were lined up with the
 
rising and setting up the Seven Sisters

50
00:03:06,540 --> 00:03:10,600
the Aztec and Mayan not only believe
 
that the world would come to an and on

51
00:03:10,600 --> 00:03:13,810
one of these plea eighties overhead at
 
midnight nights

52
00:03:13,810 --> 00:03:17,329
but we're convinced that the world had
 
already been destroyed

53
00:03:17,329 --> 00:03:20,470
and recreated four times on just such a
 
night

54
00:03:20,470 --> 00:03:23,950
should we rename them the seven sinister
 
sisters

55
00:03:23,950 --> 00:03:28,260
although the plate is no longer reach
 
their highest point

56
00:03:28,260 --> 00:03:31,740
that is calm in a exactly at midnight on
 
Halloween

57
00:03:31,740 --> 00:03:35,030
as they did in 1000 BC nevertheless

58
00:03:35,030 --> 00:03:38,890
they're still very high in the southeast
 
every Halloween at midnight

59
00:03:38,890 --> 00:03:42,690
as a modern reminder that ancestors were
 
deeply moved

60
00:03:42,690 --> 00:03:45,730
and affected by the cosmos and use many

61
00:03:45,730 --> 00:03:49,160
cosmic coincidence is to determine
 
important religious

62
00:03:49,160 --> 00:03:53,560
in ceremonial events in their life and
 
for what we can see this year

63
00:03:53,560 --> 00:03:57,970
get outside and look up after sunset at
 
the young Mounir mars next week

64
00:03:57,970 --> 00:04:01,410
and get outside this Halloween or any
 
Halloween at midnight

65
00:04:01,410 --> 00:04:04,550
look high and East for the beautiful
 
cluster stars

66
00:04:04,550 --> 00:04:08,150
known as the pleats and the Seven
 
Sisters or

67
00:04:08,150 --> 00:04:11,520
as Jack like to call my Halloween the
 
seventh sinister sisters

68
00:04:11,520 --> 00:04:15,660
and as you look at them remind yourself
 
that these same stars

69
00:04:15,660 --> 00:04:19,750
have been seen by thousands and
 
generations we've gone before us

70
00:04:19,750 --> 00:04:23,840
use all them as very important in
 
determining their own special days of

71
00:04:23,840 --> 00:04:24,500
the year

72
00:04:24,500 --> 00:04:28,460
when the honor their day and although it
 
might be a bit creepy

73
00:04:28,460 --> 00:04:32,199
don't you agree that seven sisters at
 
midnight or even better than

74
00:04:32,199 --> 00:04:36,900
performing Halloween I mean seven which
 
is before midnight

75
00:04:36,900 --> 00:04:53,580
keep looking up

76
00:04:53,580 --> 00:04:54,949
way

77
00:04:54,949 --> 00:04:59,949
ok
