00:00:08,000 --> 00:00:05,539
what's up for march a total solar

2
00:00:11,060 --> 00:00:08,010
eclipse in the north atlantic and tips

3
00:00:13,039 --> 00:00:11,070
to prepare for the next US eclipse hello

4
00:00:14,870 --> 00:00:13,049
and welcome I'm Jane Houston Jones from

5
00:00:17,810 --> 00:00:14,880
NASA's Jet Propulsion Laboratory in

6
00:00:20,330 --> 00:00:17,820
Pasadena California total eclipses of

7
00:00:23,420 --> 00:00:20,340
the Sun have puzzled an amazed observer

8
00:00:25,550 --> 00:00:23,430
since ancient times an eclipse occurs

9
00:00:27,529 --> 00:00:25,560
when one celestial body appears to

10
00:00:30,140 --> 00:00:27,539
partially or totally block the light

11
00:00:33,709 --> 00:00:30,150
from another celestial object as seen

12
00:00:35,959 --> 00:00:33,719
from a specific location solar eclipses

13
00:00:37,490 --> 00:00:35,969
can only occur during the new moon when

14
00:00:40,610 --> 00:00:37,500
the moon is between the Earth and the

15
00:00:43,549 --> 00:00:40,620
Sun and the Earth Moon and Sun form a

16
00:00:47,450 --> 00:00:43,559
straight line there are four kinds of

17
00:00:56,720 --> 00:00:47,460
solar eclipses total partial annular and

18
00:00:58,639 --> 00:00:56,730
hybrid a total solar eclipse like the

19
00:01:02,209 --> 00:00:58,649
one this month and the one visible in

20
00:01:04,340 --> 00:01:02,219
parts of the US and 2017 can only be

21
00:01:06,890 --> 00:01:04,350
seen from within a narrow track called

22
00:01:08,929 --> 00:01:06,900
the path of totality where the moon

23
00:01:13,160 --> 00:01:08,939
completely blocks our view of the sun's

24
00:01:15,530 --> 00:01:13,170
disk the cone-shaped shadow of the moon

25
00:01:18,260 --> 00:01:15,540
becomes narrower as it extends towards

26
00:01:21,350 --> 00:01:18,270
Earth therefore the path of totality is

27
00:01:25,130 --> 00:01:21,360
narrow typically 10,000 miles long but

28
00:01:27,230 --> 00:01:25,140
only about 100 miles wide the only total

29
00:01:30,980 --> 00:01:27,240
solar eclipse is visible in the u.s. in

30
00:01:33,429 --> 00:01:30,990
the last 40 years were in 1979 visible

31
00:01:39,080 --> 00:01:33,439
in the northwest part of the country in

32
00:01:41,420 --> 00:01:39,090
1991 visible in Hawaii the Babylonians

33
00:01:45,980 --> 00:01:41,430
and ancient Chinese were able to predict

34
00:01:48,679 --> 00:01:45,990
solar eclipses as early as 2500 BC but

35
00:01:50,870 --> 00:01:48,689
it wasn't until 1605 that astronomer

36
00:01:52,990 --> 00:01:50,880
Johannes Kepler made a scientific

37
00:01:55,969 --> 00:01:53,000
observation of a total solar eclipse

38
00:01:58,700 --> 00:01:55,979
more than a century later Edmond Halley

39
00:02:00,830 --> 00:01:58,710
predicted the timing and path of a total

40
00:02:03,370 --> 00:02:00,840
solar eclipse that took place on May

41
00:02:06,290 --> 00:02:03,380
third 1715

42
00:02:08,120 --> 00:02:06,300
that's why amateur astronomers like me

43
00:02:11,180 --> 00:02:08,130
are traveling to the March twentieth

44
00:02:12,800 --> 00:02:11,190
eclipse in the Faroe Islands far out in

45
00:02:16,670 --> 00:02:12,810
the North Sea hundreds of miles from

46
00:02:19,070 --> 00:02:16,680
Iceland Norway in the UK the best place

47
00:02:22,760 --> 00:02:19,080
to find out about all eclipses and where

48
00:02:26,810 --> 00:02:22,770
they are visible is that eclipse gsfc
