Telescopes able to observe several solar features concurrently, such as Sun spots

appearing as relatively cool dark areas
on the Sun's disc. their magnetic intensity

magnetic field and structural features in large
parts of the coronas. Thus from Skylab the light of the  is dim.

itself Skylab scientists created the
equivalent of thousands of brief

20
00:01:50,649 --> 00:01:56,509
Earth observations or a solar eclipse to study
the Sun's corona. Before, it was assumed

21
00:01:56,509 --> 00:02:01,670
this outer atmosphere was fairly stable
that changes occur only slowly over long

22
00:02:01,670 --> 00:02:06,920
periods of time but Skylab revealed a much more dynamic corona with many

23
00:02:06,920 --> 00:02:11,980
more changes occurring at faster rates
than was thought possible. Including this huge bubble

00:02:11,980 --> 00:02:16,880
righted by a magnetic field extending
into the outer atmosphere rapidly

25
00:02:16,880 --> 00:02:23,870
growing almost the size of Sun
itself. another telescope scanned selected

26
00:02:23,870 --> 00:02:28,459
portions of the Sun recording extreme
ultraviolet light from several layers of

27
00:02:28,459 --> 00:02:33,260
atmosphere these layers lying above the
visible surface of the Sun the

28
00:02:33,260 --> 00:02:36,350
chromosphere
the chromosphere Corona transition zone

29
00:02:36,350 --> 00:02:40,300
and the corona
were scanned simultaneously

30
00:02:40,300 --> 00:02:45,160
and a display here using various
computer generated color. In this sequence of

31
00:02:45,160 --> 00:02:50,970
ultraviolet photographs, a third is shot 
out of the chromosphere and into the corona

32
00:02:50,970 --> 00:02:56,350
by means image timed sequences, the flow of energy upward into the corona can

33
00:02:56,350 --> 00:03:01,450
be measured and balanced against the downward
flow allowing for the first time an

34
00:03:01,450 --> 00:03:07,810
accurate assessment of a dynamics of the solar
atmosphere. For the first time, Skylab

35
00:03:07,810 --> 00:03:12,160
astronauts were able to take the detailed
data of a whole Sun and the ultraviolet

36
00:03:12,160 --> 00:03:17,470
region of the spectrum. this picture shows the
areas of the sun's atmosphere which are

37
00:03:17,470 --> 00:03:22,960
between 50,000 and 100,000 degrees
Kelvin at the time of an eruption that lifted

38
00:03:22,960 --> 00:03:27,730
this twisted sheet of flame off its surface. The eruption is one of the

39
00:03:27,730 --> 00:03:32,410
largest ever recorded and it grown to
40 times the size of the earth when the

40
00:03:32,410 --> 00:03:38,290
photograph was taken. the x-ray telescopes were
designed to study the evolution of a hot

41
00:03:38,290 --> 00:03:44,550
atmosphere of the Sun. Here is an example of a rapid change in pressure

42
00:03:51,000 --> 00:03:55,830
this picture was taken at the time when
the major reconfiguration took place. at

43
00:03:55,830 --> 00:04:01,200
this time the brightest area with the
biggest emitter electric in temperature

44
00:04:01,200 --> 00:04:09,150
was in excess of four million degrees and perhaps
10 million degrees or more. Skylab studies

45
00:04:09,150 --> 00:04:14,190
of corona holes, dark areas on the area on the Sun show that they may be the source of the

46
00:04:14,190 --> 00:04:19,380
solar wind which extends beyond the planet
Jupiter coronal holes may also have

47
00:04:19,380 --> 00:04:24,660
strong magnetic boundaries as the Sun
rotates, these huge magnetic specters

48
00:04:24,660 --> 00:04:29,370
sleep on earth disturbing the upper
atmosphere there are indications that

49
00:04:29,370 --> 00:04:34,130
these disturbances correlate with the
formation of low pressure weather centers

50
00:04:34,130 --> 00:04:39,510
Additional astronomy has shown us that the Sun is far more active even violent

51
00:04:39,510 --> 00:04:44,400
than we thought. In the next few years
Skylab solar astronomy will tell us even

52
00:04:44,400 --> 00:04:49,680
more about the Sun, but also about our
planet Earth a cool island within the
