6
00:00:35.039 --> 00:00:43.479
depths with a fiery tale slashing across
the night sky. Commet twelve Pea Pons

7
00:00:43.560 --> 00:00:49.960
Brooks, also known as the Devil
Comet, has captivated skywatchers for centuries,

8
00:00:51.320 --> 00:00:57.880
earning its nickname due to its occasional, unpredictable outbursts of brightness. This icy

9
00:00:58.039 --> 00:01:03.439
wanderer from the outer reaches of our
Solar system is set to grace our skies

10
00:01:03.520 --> 00:01:10.359
once again in April twenty twenty four
as it approaches Earth. Let's embark on

11
00:01:10.439 --> 00:01:17.519
an exploration of the Devil Comet,
unraveling its secrets, history and significance in

12
00:01:17.560 --> 00:01:26.879
the Grand Cosmic Dance. A tale
of two discoveries, unveiling the comets legacy.

13
00:01:27.799 --> 00:01:34.480
The Devil comet boasts a rich history
marked by multiple discoveries and a name

14
00:01:34.640 --> 00:01:42.000
reflecting the independent efforts of two astronomers. In eighteen twelve, French astronomer Jean

15
00:01:42.079 --> 00:01:49.400
Louis Pon's first spot of the comet
during a routine observation. Ponds, a

16
00:01:49.480 --> 00:01:57.599
meticulous observer known for discovering numerous comets, wasn't initially aware of the significance of

17
00:01:57.640 --> 00:02:05.640
his find The comet's return after its
elliptical orbit brought it back into view in

18
00:02:05.719 --> 00:02:14.479
eighteen eighty three. This time,
American astronomer William Robert Brooks independently rediscovered the

19
00:02:14.560 --> 00:02:21.680
comet, unaware of Pond's earlier observation. Due to this dual discovery, the

20
00:02:21.800 --> 00:02:27.360
comet now bears the combined name twelve
p Pond's Brooks, a testament to the

21
00:02:27.400 --> 00:02:35.680
collaborative spirit of astronomy. The story
also highlights the importance of meticulous record keeping

22
00:02:35.800 --> 00:02:43.520
in astronomy, as Ponn's initial observations, though not immediately recognized, proved crucial

23
00:02:43.639 --> 00:02:53.759
in identifying the comet's return a Holly
type comet, understanding the Devil's orbit.

24
00:02:55.360 --> 00:03:00.919
Comets are classified based on their orbital
periods, the time it takes for them

25
00:03:01.000 --> 00:03:08.280
to complete one revolution around the Sun. Unlike planets with nearly circular orbits,

26
00:03:08.800 --> 00:03:15.280
comets follow elliptical paths that bring them
closer to the Sun at one point and

27
00:03:15.439 --> 00:03:22.000
much farther away at another. The
Devil Comet belongs to the Halle type comet

28
00:03:22.080 --> 00:03:29.960
family, characterized by orbital periods ranging
from twenty to two hundred years. These

29
00:03:30.000 --> 00:03:36.560
are considered short period comets compared to
some long period comets that venture far beyond

30
00:03:36.599 --> 00:03:42.000
the grasp of the Sun's gravity,
taking thousands of years to complete a single

31
00:03:42.120 --> 00:03:49.319
orbit. Twelve p Ponds Brooks follows
a relatively short elliptical orbit, bringing it

32
00:03:49.400 --> 00:03:55.520
back to the Inner Solar System every
seventy one years. This frequent return allows

33
00:03:55.560 --> 00:04:03.080
astronomers to study the comet in greater
detail during each apparition, providing valuable insights

34
00:04:03.159 --> 00:04:12.159
into its physical characteristics and changes over
time. The Devil comets orbit doesn't just

35
00:04:12.280 --> 00:04:16.279
bring it close to the Sun,
it also brings it into close proximity to

36
00:04:16.399 --> 00:04:23.879
Earth. In fact, during its
twenty twenty four return, the comet is

37
00:04:24.000 --> 00:04:30.240
expected to make its closest approach to
our planet in June, offering skywatchers a

38
00:04:30.319 --> 00:04:38.720
spectacular opportunity to witness this celestial visitor. Unlike some comets that remain faint and

39
00:04:38.800 --> 00:04:45.240
require telescopes for observation, twelve p
Ponds Brooks has the potential to be visible

40
00:04:45.319 --> 00:04:49.240
to the naked eye under dark skies, making it a prime target for both

41
00:04:49.319 --> 00:05:01.000
season astronomers and curious stargezers. A
cryo volcanic heart unveiling the devil's outbursts.

42
00:05:03.600 --> 00:05:11.120
One of the most captivating characteristics of
twelve pe Ponds Brooks is its dramatic outbursts.

43
00:05:12.560 --> 00:05:17.360
Unlike most comets that gradually brighten as
they approach the sun, Bedevil Comet

44
00:05:17.439 --> 00:05:26.040
exhibits sudden and unpredictable increases in brightness. These outbursts can occur within a few

45
00:05:26.120 --> 00:05:30.720
days, causing the comet to become
tens or even hundreds of times brighter.

46
00:05:32.199 --> 00:05:40.319
Scientists believe these outbursts are a result
of cryovolcanism, a process similar to volcanism

47
00:05:40.399 --> 00:05:45.959
on Earth, but involving the eruption
of ices and gases instead of molten rock.

48
00:05:46.360 --> 00:05:53.959
Bedevil comets icy nucleus likely harbors pockets
of frozen gases like water, vapor,

49
00:05:54.480 --> 00:06:00.439
methane, in ammonia trapped beneath its
surface crust as the comet approaches the

50
00:06:00.480 --> 00:06:08.279
Sun, the increasing heat triggers the
sublimation of these ices, transforming them directly

51
00:06:08.360 --> 00:06:14.600
from a solid to a gas.
This rapid phase change creates a pressure build

52
00:06:14.680 --> 00:06:19.879
up within the comet, eventually leading
to eruptions that expel dust and gas into

53
00:06:19.920 --> 00:06:27.639
space. These eruptions cause the sudden
increase in the comet's brightness, burning it

54
00:06:27.720 --> 00:06:35.680
the Devil Comet moniker, a dusty
legacy the Devil Comet and meteor showers.

55
00:06:40.680 --> 00:06:46.240
The Devil Comet's outbursts have a lasting
impact on our solar system. As the

56
00:06:46.279 --> 00:06:53.360
comet ejects dust and gas during its
outbursts, these particles spread out along its

57
00:06:53.480 --> 00:06:59.959
orbital path. When Earth intersects this
path, we experience a meteor shower,

58
00:07:00.720 --> 00:07:08.240
a dazzling celestial display where numerous meteors
streak across the night sky. The most

59
00:07:08.360 --> 00:07:14.959
prominent meteor shower associated with twelve p
Ponds Brooks is the Ponds Brookshare Shower,

60
00:07:15.360 --> 00:07:21.720
which typically peaks in late July.
During this shower, skywatchers can expect to

61
00:07:21.800 --> 00:07:29.639
see a few meteors per hour under
ideal observing conditions. While not as intense

62
00:07:29.680 --> 00:07:34.879
as some other meteor showers, the
Ponds Brookshire Shower holds a special significance.

63
00:07:36.279 --> 00:07:44.000
By observing these meteors, scientists can
analyze the composition of the dust particles and

64
00:07:44.120 --> 00:07:49.480
gain valuable insights into the materials that
make up the Devil Comet and potentially the

65
00:07:49.519 --> 00:08:01.720
early Solar system. A compositional mystery
peering into the Devil's icy heart, The

66
00:08:01.720 --> 00:08:09.160
Devil Comet's icy nucleus remains shrouded in
some mystery. While scientists have a good

67
00:08:09.279 --> 00:08:16.480
understanding of the comet's overall composition based
on analyzes of dust ejected during outbursts,

68
00:08:16.920 --> 00:08:24.319
directly studying the nucleus is a challenge. However, advancements in astronomical techniques and

69
00:08:24.480 --> 00:08:35.080
future space missions could shed more light
on the comet's internal makeup. Ground based

70
00:08:35.120 --> 00:08:41.639
telescopes and spacecraft observations have provided clues
about the presence of various molecules in the

71
00:08:41.679 --> 00:08:48.559
comet, including water, vapor,
carbon monoxide, and simple organic molecules.

72
00:08:50.919 --> 00:08:56.159
These findings suggest that the Devil comet
contains the basic building blocks for life as

73
00:08:56.200 --> 00:09:03.840
we know it. However, further
investigation is needed to determine the specific composition

74
00:09:05.120 --> 00:09:11.919
and abundance of these molecules within the
comet's nucleus. Future space missions designed to

75
00:09:13.080 --> 00:09:18.399
rendezvous with comets or send probes to
their surface could provide the opportunity to directly

76
00:09:18.519 --> 00:09:26.559
sample and analyze the comet's icy material, offering a more comprehensive understanding of its

77
00:09:26.559 --> 00:09:35.159
composition and potential role in the early
history of the Solar System. A celestial
