<v Speaker 1>with our soothing Bedtime Astronomy podcast. Each episode offers a

3
00:00:12.359 --> 00:00:16.320
<v Speaker 1>gentle journey through the stars, planets, and beyond, perfect for

4
00:00:16.399 --> 00:00:20.239
<v Speaker 1>unwinding after a long day. Let's travel through the mysteries

5
00:00:20.239 --> 00:00:22.440
<v Speaker 1>of the universe as you drift off into a peaceful

6
00:00:22.480 --> 00:00:29.120
<v Speaker 1>slumber under the night sky. This week in Astronomy, AI

7
00:00:29.320 --> 00:00:34.799
<v Speaker 1>Exoplanet Analysis, Outer Solar System, Hidden Objects, and black Hole Dance.

8
00:00:37.799 --> 00:00:47.000
<v Speaker 1>AI revolutionizes exoplanet atmosphere analysis. Researchers from LMU Munich, the

9
00:00:47.159 --> 00:00:53.679
<v Speaker 1>Origin's Excellence Cluster, the Max Planck Institute for Extraterrestrial Physics MPE,

10
00:00:54.280 --> 00:00:58.560
<v Speaker 1>and the Origins Data Science Lab ODSL have made a

11
00:00:58.640 --> 00:01:05.920
<v Speaker 1>significant breakthrough in exoplanet research. By leveraging physics informed neural

12
00:01:06.000 --> 00:01:10.480
<v Speaker 1>networks PINS. The team has developed a more precise method

13
00:01:10.640 --> 00:01:16.760
<v Speaker 1>for modeling the complex light scattering in exoplanet atmospheres. This

14
00:01:17.040 --> 00:01:21.439
<v Speaker 1>advancement promises to enhance our understanding of these distant worlds,

15
00:01:21.879 --> 00:01:27.319
<v Speaker 1>particularly with respect to the influence of clouds. But an

16
00:01:27.359 --> 00:01:31.200
<v Speaker 1>exoplanet passes in front of its star, a small portion

17
00:01:31.319 --> 00:01:36.040
<v Speaker 1>of the starlight is blocked. A tiny fraction of this

18
00:01:36.200 --> 00:01:41.120
<v Speaker 1>light penetrates the planet's atmosphere, interacting with its constituents and

19
00:01:41.200 --> 00:01:48.159
<v Speaker 1>leaving a unique spectral signature. Analyzing these spectral variations provides

20
00:01:48.280 --> 00:01:55.239
<v Speaker 1>clues about the atmosphere's composition, temperature, and cloud cover. To

21
00:01:55.400 --> 00:02:01.120
<v Speaker 1>interpret these spectral signatures accurately, scientists need more capable of

22
00:02:01.239 --> 00:02:08.159
<v Speaker 1>generating millions of synthetic spectra quickly. Traditional methods have struggled

23
00:02:08.240 --> 00:02:12.759
<v Speaker 1>to capture the intricacies of light scattering, particularly when clouds

24
00:02:12.800 --> 00:02:21.479
<v Speaker 1>are involved. Pins, however, offer a more efficient solution. These

25
00:02:21.560 --> 00:02:26.120
<v Speaker 1>AI powered models can solve complex equations with greater precision,

26
00:02:26.680 --> 00:02:34.680
<v Speaker 1>enabling researchers to simulate light scattering more realistically. The team's research,

27
00:02:35.159 --> 00:02:39.319
<v Speaker 1>published in the Monthly Notices of the Royal Astronomical Society,

28
00:02:39.759 --> 00:02:46.039
<v Speaker 1>represents a significant step forward in exoplanet studies. It opens

29
00:02:46.120 --> 00:02:51.439
<v Speaker 1>up new possibilities for analyzing exoplanet atmospheres, especially as we

30
00:02:51.520 --> 00:02:58.319
<v Speaker 1>receive increasingly detailed observations from the James Web Space Telescope JWST.

31
00:03:00.439 --> 00:03:05.159
<v Speaker 1>By combining physics and AI, the researchers have demonstrated the

32
00:03:05.159 --> 00:03:13.080
<v Speaker 1>power of interdisciplinary collaboration. This approach not only advances exoplanet research,

33
00:03:13.240 --> 00:03:16.240
<v Speaker 1>but also sets a precedent for the development of AI

34
00:03:16.360 --> 00:03:21.560
<v Speaker 1>based methods in other fields of physics. As the team

35
00:03:21.759 --> 00:03:26.080
<v Speaker 1>continues to refine their models and explore new applications, we

36
00:03:26.159 --> 00:03:30.280
<v Speaker 1>can expect even more exciting discoveries about the atmospheres of

37
00:03:30.360 --> 00:03:39.759
<v Speaker 1>distant worlds. A revised version the Outer Solar System a

38
00:03:39.840 --> 00:03:47.800
<v Speaker 1>hidden population. Recent observations with the Subaru Telescope have unveiled

39
00:03:47.800 --> 00:03:52.319
<v Speaker 1>the previously unseen population of celestial bodies in the Outer

40
00:03:52.479 --> 00:03:59.919
<v Speaker 1>Solar System. These findings, far from being isolated incidents, suggests

41
00:04:00.120 --> 00:04:06.439
<v Speaker 1>a much larger undiscovered community of objects beyond Neptune. This

42
00:04:06.680 --> 00:04:10.960
<v Speaker 1>discovery has profound implications for our understanding of the Solar

43
00:04:11.039 --> 00:04:16.199
<v Speaker 1>System's formation structure in its place within the broader context

44
00:04:16.240 --> 00:04:23.439
<v Speaker 1>of planetary systems. The Subaru Telescope, a powerful instrument located

45
00:04:23.480 --> 00:04:30.959
<v Speaker 1>atop Mounakia in Hawaii, has been instrumental in these groundbreaking observations.

46
00:04:32.199 --> 00:04:36.399
<v Speaker 1>Its primary goal has been to support NASA's New Horizons mission,

47
00:04:36.839 --> 00:04:40.759
<v Speaker 1>the first spacecraft to explore the Kuiper Belt, a region

48
00:04:40.879 --> 00:04:49.120
<v Speaker 1>beyond Neptune. By identifying intriguing Kuiper Belt objects KBOs, Subaru

49
00:04:49.160 --> 00:04:55.399
<v Speaker 1>has been helping New Horizons plant its exploration route while

50
00:04:55.519 --> 00:04:59.279
<v Speaker 1>previous studies have hinted at the existence of objects beyond

51
00:04:59.279 --> 00:05:04.519
<v Speaker 1>the known Kype Belt. Subaru's recent findings are particularly significant

52
00:05:04.600 --> 00:05:07.600
<v Speaker 1>due to the sheer number of objects discovered in a

53
00:05:07.680 --> 00:05:14.319
<v Speaker 1>relatively small search area. These eleven newly identified objects appear

54
00:05:14.399 --> 00:05:18.040
<v Speaker 1>to form a distinct ring, separated from the main Kuiper

55
00:05:18.120 --> 00:05:22.720
<v Speaker 1>Belt by a relatively empty gap. This ring and gap

56
00:05:22.759 --> 00:05:26.319
<v Speaker 1>structure is reminiscent of the outer regions of many young

57
00:05:26.399 --> 00:05:33.160
<v Speaker 1>planetary systems observed by the Alma radio telescope array. Doctor

58
00:05:35.199 --> 00:05:42.160
<v Speaker 1>Fumi Yoshida and doctor West Fraser, leading researchers involved in

59
00:05:42.199 --> 00:05:46.519
<v Speaker 1>the study, have emphasized the groundbreaking nature of this discovery.

60
00:05:48.439 --> 00:05:52.240
<v Speaker 1>The existence of a second ring of KBOs suggests that

61
00:05:52.279 --> 00:05:56.120
<v Speaker 1>the primordial solar nebula, the cloud of gas and dust

62
00:05:56.199 --> 00:05:59.759
<v Speaker 1>from which the Solar System formed, was much larger than

63
00:05:59.759 --> 00:06:06.160
<v Speaker 1>pre previously thought. This has significant implications for understanding the

64
00:06:06.199 --> 00:06:12.600
<v Speaker 1>planet formation process within our own cosmic neighborhood. The findings

65
00:06:12.720 --> 00:06:15.800
<v Speaker 1>challenge the long held notion that the Kuiper Belt is

66
00:06:15.839 --> 00:06:21.560
<v Speaker 1>a relatively small and insignificant feature of the Solar System.

67
00:06:22.120 --> 00:06:25.480
<v Speaker 1>It suggests that our understanding of this region may have

68
00:06:25.560 --> 00:06:31.439
<v Speaker 1>been limited by observational biases. The discovery of a hidden

69
00:06:31.519 --> 00:06:35.240
<v Speaker 1>population of objects in the Outer Solar System opens up

70
00:06:35.279 --> 00:06:40.680
<v Speaker 1>new avenues for exploration and research. One of the most

71
00:06:40.720 --> 00:06:44.519
<v Speaker 1>profound implications of this discovery lies in the search for

72
00:06:44.639 --> 00:06:51.279
<v Speaker 1>extraterrestrial life. The existence of a larger solar nebula suggests

73
00:06:51.360 --> 00:06:54.959
<v Speaker 1>that the formation of our Solar system was less unusual

74
00:06:55.040 --> 00:07:00.839
<v Speaker 1>than previously thought. This increases the likelihood of finding other

75
00:07:00.959 --> 00:07:06.519
<v Speaker 1>planetary systems with similar characteristics, potentially raising the odds of

76
00:07:06.600 --> 00:07:14.279
<v Speaker 1>discovering habitable worlds. The Subaru Telescope's observations have revealed a

77
00:07:14.360 --> 00:07:19.000
<v Speaker 1>hidden population of objects in the Outer Solar System, challenging

78
00:07:19.040 --> 00:07:25.160
<v Speaker 1>our existing understanding of this region. These findings have significant

79
00:07:25.160 --> 00:07:30.120
<v Speaker 1>implications for planetary science and the search for extraterrestrial life.

80
00:07:32.079 --> 00:07:36.399
<v Speaker 1>As future studies delve deeper into this newly discovered population,

81
00:07:36.920 --> 00:07:40.560
<v Speaker 1>we can expect to gain valuable insights into the formation

82
00:07:40.800 --> 00:07:49.600
<v Speaker 1>and evolution of our Solar system. A cosmic dance two

83
00:07:49.800 --> 00:07:57.240
<v Speaker 1>supermassive black holes in close proximity. Astronomers have made a

84
00:07:57.319 --> 00:08:01.519
<v Speaker 1>groundbreaking discovery a pair of suits super massive black holes

85
00:08:01.560 --> 00:08:06.720
<v Speaker 1>in extraordinarily close proximity within a gas rich galaxy MCG

86
00:08:06.920 --> 00:08:13.480
<v Speaker 1>zero three, three, four six four. Located approximately three hundred

87
00:08:13.600 --> 00:08:17.920
<v Speaker 1>light years apart, these cosmic behemoths are actively feeding on

88
00:08:18.000 --> 00:08:23.040
<v Speaker 1>infalling gas and dust, shining brightly as active galactic nuclei.

89
00:08:23.439 --> 00:08:30.839
<v Speaker 1>Agn Using NASA's Hubble Space telescope and Chundra X ray observatory,

90
00:08:31.399 --> 00:08:35.480
<v Speaker 1>scientists observe these black holes nestled deep within a pair

91
00:08:35.519 --> 00:08:42.039
<v Speaker 1>of colliding galaxies. Their close proximity and intense activity make

92
00:08:42.120 --> 00:08:45.279
<v Speaker 1>them a prime target for studying the early stages of

93
00:08:45.360 --> 00:08:50.320
<v Speaker 1>galaxy mergers and the eventual coalescence of supermassive black holes.

94
00:08:52.240 --> 00:08:56.600
<v Speaker 1>While several dozen dual black holes have been previously identified,

95
00:08:57.000 --> 00:09:01.039
<v Speaker 1>their separations are typically much greater than what was discovered

96
00:09:01.080 --> 00:09:06.919
<v Speaker 1>in MCG zero three three four six four. This newly

97
00:09:07.000 --> 00:09:10.799
<v Speaker 1>found pair offers a unique opportunity to observe a nearby

98
00:09:10.879 --> 00:09:14.039
<v Speaker 1>example of a phenomenon that was more common in the

99
00:09:14.080 --> 00:09:21.000
<v Speaker 1>early universe when galaxy mergers were more frequent. The discovery

100
00:09:21.080 --> 00:09:28.559
<v Speaker 1>was serendipitous. Pubble's high resolution imaging revealed distinctive diffraction spikes

101
00:09:28.600 --> 00:09:33.320
<v Speaker 1>within the host galaxy, indicating a concentration of glowing oxygen

102
00:09:33.399 --> 00:09:38.159
<v Speaker 1>gas in a small area. We weren't expecting to see

103
00:09:38.200 --> 00:09:42.320
<v Speaker 1>something like this, said anatrendade fo Cow, lead author of

104
00:09:42.360 --> 00:09:48.759
<v Speaker 1>the study published in the Astrophysical Journal. Further analysis using

105
00:09:48.919 --> 00:09:53.159
<v Speaker 1>Chundra's X ray observations confirmed the presence of two separate

106
00:09:53.519 --> 00:09:57.320
<v Speaker 1>powerful sources of high energy emission coinciding with the bright

107
00:09:57.399 --> 00:10:02.799
<v Speaker 1>optical points of light seen by Hubble. Combined with radio

108
00:10:02.960 --> 00:10:08.639
<v Speaker 1>data from the Carl G. Jansky very Large ray, these

109
00:10:08.720 --> 00:10:13.200
<v Speaker 1>observations strongly support the conclusion that the galaxy hosts a

110
00:10:13.240 --> 00:10:19.399
<v Speaker 1>pair of closely spaced supermassive black holes. The third source

111
00:10:19.440 --> 00:10:23.039
<v Speaker 1>of bright light observed by Hubble remains a mystery, but

112
00:10:23.120 --> 00:10:26.000
<v Speaker 1>it could be gas that is being shocked by energy

113
00:10:26.080 --> 00:10:29.320
<v Speaker 1>from a jet of ultra high speed plasma fired from

114
00:10:29.360 --> 00:10:34.720
<v Speaker 1>one of the black holes. As these supermassive black holes

115
00:10:34.879 --> 00:10:39.960
<v Speaker 1>continue to spiral closer together, they will eventually merge, creating

116
00:10:40.000 --> 00:10:46.840
<v Speaker 1>a powerful gravitational wave event. While the Laser Interferometer Gravitational

117
00:10:46.879 --> 00:10:52.320
<v Speaker 1>Wave Observatory LIGO has detected gravitational waves from mergers of

118
00:10:52.440 --> 00:10:57.440
<v Speaker 1>stellar mass black holes, the longer wavelengths produced by supermassive

119
00:10:57.480 --> 00:11:04.039
<v Speaker 1>black hole mergers are beyond its capabilit The upcoming lease emission,

120
00:11:04.440 --> 00:11:07.720
<v Speaker 1>led by the European Space Agency will be able to

121
00:11:07.759 --> 00:11:15.080
<v Speaker 1>detect these elusive gravitational waves from deep space. The discovery

122
00:11:15.120 --> 00:11:19.600
<v Speaker 1>of this close binary supermassive black hole system has significant

123
00:11:19.639 --> 00:11:24.240
<v Speaker 1>implications for our understanding of galaxy evolution and the formation

124
00:11:24.399 --> 00:11:30.320
<v Speaker 1>of supermassive black holes. It provides a unique laboratory for

125
00:11:30.440 --> 00:11:34.759
<v Speaker 1>studying the dynamics of interacting galaxies and the processes that

126
00:11:34.840 --> 00:11:40.279
<v Speaker 1>drive the growth of black holes. Future observations of this

127
00:11:40.399 --> 00:11:43.639
<v Speaker 1>system will help to refine our understanding of the black

128
00:11:43.639 --> 00:11:51.879
<v Speaker 1>hole's masses, spins, and orbital properties. Additionally, studying the surrounding

129
00:11:51.960 --> 00:11:56.039
<v Speaker 1>gas and dust can provide insights into the fueling mechanisms

130
00:11:56.080 --> 00:11:59.759
<v Speaker 1>of active galactic nuclei and the impact of black hole

131
00:11:59.799 --> 00:12:05.879
<v Speaker 1>eye activity on their host galaxies. The detection of gravitational

132
00:12:05.919 --> 00:12:09.360
<v Speaker 1>waves from the eventual merger of these black holes will

133
00:12:09.360 --> 00:12:12.879
<v Speaker 1>provide a direct probe of the strong gravity regime and

134
00:12:13.000 --> 00:12:19.080
<v Speaker 1>test fundamental theories of general relativity. It will also offer

135
00:12:19.120 --> 00:12:22.879
<v Speaker 1>a new window into the cosmic history of galaxy mergers

136
00:12:23.039 --> 00:12:26.639
<v Speaker 1>and the formation of the most massive structures in the universe.

137
00:13:28.559 --> 00:14:02.080
<v Speaker 1>To get to be a m
