Calorogus shark media. In the outer
reaches of our Solar System lies Neptune,

2
00:00:13.199 --> 00:00:17.239
the eighth and farthest known planet from
the Sun. A world of mystery and

3
00:00:17.280 --> 00:00:22.199
beauty, Neptune is a giant planet. Its striking blue coloration a result of

4
00:00:22.280 --> 00:00:29.800
methane in its atmosphere, absorbing red
light and reflecting the enchanting blue. This

5
00:00:29.920 --> 00:00:34.280
distant planet, named after the Roman
god of the sea, mirrors the deep,

6
00:00:34.600 --> 00:00:39.799
enigmatic ocean blues of Earth. Neptune's
atmosphere is dynamic and ever changing.

7
00:00:40.439 --> 00:00:45.679
High thin clouds drift in its upper
atmosphere, and the planet experiences violent weather

8
00:00:45.759 --> 00:00:49.799
patterns, with the strongest winds in
the Solar System, reaching up to thirteen

9
00:00:49.880 --> 00:00:55.679
hundred miles per hour. These supersonic
winds sculpt and twist the clouds, creating

10
00:00:55.719 --> 00:01:00.719
a mesmerizing dance in the planet's atmosphere. One of Neptune's most notable features is

11
00:01:00.759 --> 00:01:06.400
the Great Dark Spot, a massive
storm similar to Jupiter's Great Red Spot.

12
00:01:07.159 --> 00:01:11.120
This storm, however, is not
permanent. When the Voyager two spacecraft flew

13
00:01:11.120 --> 00:01:15.799
by in nineteen eighty nine, it
captured images of this giant storm, but

14
00:01:15.959 --> 00:01:21.920
later observations by the Hubble Space Telescope
found that it had disappeared, only for

15
00:01:22.040 --> 00:01:30.640
new storms to form elsewhere on the
planet. Neptune is a frozen world,

16
00:01:30.680 --> 00:01:34.359
with temperatures plunging to minus three point
fifty three degrees fahrenheit. Despite being a

17
00:01:34.400 --> 00:01:40.400
gas giant, Neptune has a surprisingly
rapid rotation, completing one turn on its

18
00:01:40.439 --> 00:01:46.359
axis in about sixteen hours. This
rapid rotation causes strong storms and an interesting

19
00:01:46.400 --> 00:01:51.959
phenomenon in its magnetic field. Unlike
Earth, where the magnetic field is aligned

20
00:01:51.959 --> 00:01:57.760
closely with the rotation axis, Neptune's
magnetic field is tipped over by a staggering

21
00:01:57.879 --> 00:02:00.959
forty seven degrees and is off said
at least eighty five hundred miles from the

22
00:02:01.000 --> 00:02:10.439
planet's physical center. The atmosphere of
Neptune is one of its most fascinating features,

23
00:02:10.960 --> 00:02:16.080
composed primarily of hydrogen and helium with
traces of methane. This mixture gives

24
00:02:16.120 --> 00:02:22.680
Neptune its signature blue color. The
high altitude clouds cast shadows on the opaque

25
00:02:22.680 --> 00:02:27.639
cloud deck below. These clouds are
made of frozen methane drifting across the sky

26
00:02:27.759 --> 00:02:31.199
at high speeds due to the planet's
extreme winds. The weather on Neptune is

27
00:02:31.240 --> 00:02:36.759
intense and violent. The strongest winds
across the Solar System are found here,

28
00:02:37.120 --> 00:02:42.000
reaching speeds of more than thirteen hundred
miles per hour. These winds whip around

29
00:02:42.039 --> 00:02:46.080
the planet faster than the speed of
sound in some regions. This extreme weather

30
00:02:46.159 --> 00:02:50.800
is believed to be driven by the
flow of internal heat from the planet's core,

31
00:02:51.120 --> 00:02:54.080
which is about one point five to
two point five times the solar energy

32
00:02:54.120 --> 00:03:00.080
Neptune receives. Despite being a gas
giant, Neptune has a distinct internal structure.

33
00:03:00.479 --> 00:03:05.719
At its core, Neptune harbours a
solid center roughly the size of Earth,

34
00:03:06.039 --> 00:03:09.319
composed of rock and ice. This
core is enveloped by a mantle of

35
00:03:09.360 --> 00:03:15.159
water, ammonia, and methane ices, over which lies the outer gaseous atmosphere.

36
00:03:15.800 --> 00:03:20.840
This structure is quite different from the
gas giants Jupiter and Saturn, with

37
00:03:20.919 --> 00:03:30.639
their larger metallic hydrogen layers. The
magnetic field of Neptune is about twenty seven

38
00:03:30.639 --> 00:03:36.199
times more powerful than Earth's. Intriguingly, this magnetic field is highly tilted and

39
00:03:36.280 --> 00:03:40.800
offset from the planet's rotation axis.
The fields strange orientation may be due to

40
00:03:40.840 --> 00:03:46.039
the field being generated by conductive materials
like water, ammonia and methane in the

41
00:03:46.080 --> 00:03:54.039
planet's mantle rather than its core.
Neptune's ring system is less famous than Saturn's,

42
00:03:54.199 --> 00:03:59.560
but no less intriguing. The rings
are made up of fine dust particles

43
00:03:59.719 --> 00:04:04.479
thought to have been made by tiny
meteorites smashing into Neptune's moons. These rings

44
00:04:04.479 --> 00:04:11.319
are named after astronomers who made significant
contributions to the study of neptune atoms,

45
00:04:11.639 --> 00:04:16.399
Arago, Gal, Lassel, and
Leverrier. The rings vary in their composition

46
00:04:16.519 --> 00:04:21.560
and structure. Some are complete rings, while others are incomplete arcs. This

47
00:04:21.759 --> 00:04:26.920
unique arc structure is not well understood, but it's thought to be due to

48
00:04:26.959 --> 00:04:35.240
the gravitational interaction with Neptune's moons.
Neptune holds a special place in Solar System

49
00:04:35.279 --> 00:04:41.720
exploration. It's a window into the
outer Solar System, a region vastly different

50
00:04:41.759 --> 00:04:46.920
from the terrestrial planets or the gas
giants. Understanding Neptune helps astronomers piece together

51
00:04:47.000 --> 00:04:53.000
the formation and evolution of our Solar
System, and gives insights into similar planets

52
00:04:53.040 --> 00:05:13.680
around other stars. Neptune has fourteen
known moons, each with its own story.

53
00:05:14.319 --> 00:05:18.319
Triton, the largest of Neptune's moons, is particularly fascinating. It orbits

54
00:05:18.360 --> 00:05:24.160
Neptune in a direction opposite to the
planet's rotation, a retrograde orbit, which

55
00:05:24.199 --> 00:05:28.399
suggests that Triton may have been captured
by Neptune's gravity and was not formed in

56
00:05:28.480 --> 00:05:33.560
place. Triton is extremely cold,
with surface temperatures around three ninety one degrees

57
00:05:33.680 --> 00:05:40.160
fahrenheit. Despite this, Triton has
active geology. It's one of the few

58
00:05:40.279 --> 00:05:46.000
geologically active moons in the Solar System, with cryovolcanoes that erupt with plumes of

59
00:05:46.079 --> 00:05:54.560
nitrogen. Another intriguing moon is Proteus, the second largest moon of Neptune and

60
00:05:54.680 --> 00:05:58.959
one of the darkest objects in the
Solar System. It's heavily cratered, with

61
00:05:59.079 --> 00:06:05.600
a surface covered in irregular terrain,
deep canyons and scarps. Nearid, the

62
00:06:05.639 --> 00:06:10.759
third largest moon of Neptune, has
one of the most eccentric orbits of any

63
00:06:10.800 --> 00:06:15.680
moon in our Solar system, suggesting
a violent history of collisions and captures.

64
00:06:16.160 --> 00:06:21.040
Larisa, another moon, was discovered
when it occulted a star, revealing its

65
00:06:21.079 --> 00:06:29.879
presence to astronomers. Closer to Neptune, a group of small moons niad Thalassa,

66
00:06:30.040 --> 00:06:34.439
Despina Galatea, and Larisa weave a
complex dance as they orbit within Neptune's

67
00:06:34.480 --> 00:06:39.480
system of rings. These rings are
not as prominent as Saturns, but have

68
00:06:39.519 --> 00:06:44.879
a charm of their own. They're
composed of dark material, likely organic compounds

69
00:06:44.920 --> 00:06:49.160
processed by radiation, similar to the
material found in the rings of Uranus.

70
00:06:50.759 --> 00:06:57.959
Neptune was the first planet located through
mathematical predictions rather than through regular observations of

71
00:06:58.000 --> 00:07:02.519
the sky. Its discovery in eighteen
forty six was a remarkable achievement, marking

72
00:07:02.600 --> 00:07:08.399
a significant moment in the history of
astronomy. Its position was calculated based on

73
00:07:08.480 --> 00:07:13.480
irregularities in the orbit of Uranus,
pointing astronomers to its hidden location in the

74
00:07:13.560 --> 00:07:20.360
night sky. Neptune's orbit is incredibly
long. It completed its first observed orbit

75
00:07:20.439 --> 00:07:26.000
since its discovery only in twenty eleven. This distant planet takes about one hundred

76
00:07:26.040 --> 00:07:29.920
and sixty five Earth years to complete
a single orbit around the Sun. Each

77
00:07:29.959 --> 00:07:36.800
season on Neptune lasts for over forty
earth years. As our journey to the

78
00:07:36.839 --> 00:07:42.439
distant and enchanting world of Neptune comes
to a close, let its deep blue

79
00:07:42.480 --> 00:07:54.199
mystery and the dance of its moons
lull you into a peaceful sleep. Imagine

80
00:07:54.279 --> 00:07:58.800
drifting in the calm, blue expanse
of Neptune, cradled by the cold but

81
00:07:58.879 --> 00:08:03.480
beautiful embrace of the outer Solar System. Thank you for joining us on this

82
00:08:03.600 --> 00:08:11.000
voyage to the edge of our celestial
neighborhood. From sleep, from space,

83
00:08:11.120 --> 00:08:15.800
we wish you a RESTful night dreaming
under the watchful gaze of the distant planets

84
00:08:16.079 --> 00:08:20.839
until our next cosmic exploration. Good
night, and let the mysteries of Neptune

85
00:08:20.959 --> 00:08:22.800
guide you into tranquil dreams.
