00:00:02,240 --> 00:00:05,320
Speaker 1: Welcome listeners to Astronomy Daily, your go to podcast for

2
00:00:05,360 --> 00:00:08,800
the latest updates and fascinating facts about space and astronomy.

3
00:00:09,279 --> 00:00:13,160
I'm Ana your friendly host. Today, we've got an exciting

4
00:00:13,199 --> 00:00:17,039
lineup of news topics to discuss. First, we'll delve into

5
00:00:17,120 --> 00:00:21,000
NASA's remarkable achievement of streaming four K video footage from

6
00:00:21,000 --> 00:00:25,679
an aircraft to the International Space Station. Next, we'll uncover

7
00:00:25,719 --> 00:00:29,160
the astonishing discovery of a diamond mantle beneath Mercury's crust.

8
00:00:30,000 --> 00:00:34,560
Then we'll explore the groundbreaking ionospheric insights from NASA's recently

9
00:00:34,560 --> 00:00:38,679
concluded Icon mission, and finally we'll marvel at the James

10
00:00:38,679 --> 00:00:41,479
Webb Space Telescopes imaging of a super Jupiter in the

11
00:00:41,479 --> 00:00:44,719
Epsilon Indie system. So buckle up and get ready for

12
00:00:44,759 --> 00:00:50,560
a journey through the Cosmos. Recently, a team at NASA's

13
00:00:50,560 --> 00:00:54,399
Glenn Research Center in Cleveland achieved something extraordinary. They streamed

14
00:00:54,439 --> 00:00:57,280
four K video footage from an aircraft to the International

15
00:00:57,280 --> 00:01:00,320
Space Station and back marking, the first time this has

16
00:01:00,359 --> 00:01:04,760
been done using optical laser communications. This groundbreaking technology can

17
00:01:04,799 --> 00:01:08,079
transmit data ten to one hundred times faster than traditional

18
00:01:08,159 --> 00:01:12,200
radio frequency systems. Imagine the possibilities this opens up for

19
00:01:12,239 --> 00:01:16,799
future lunar missions. Historically, NASA has relied on radio waves

20
00:01:16,840 --> 00:01:20,519
to send information to and from space, but laser communications

21
00:01:20,599 --> 00:01:23,760
utilize infrared light, which can carry much more data at

22
00:01:23,840 --> 00:01:27,439
higher speeds. For these tests, the engineers installed a portable

23
00:01:27,519 --> 00:01:30,439
laser terminal on the belly of a Polattis PC twelve

24
00:01:30,519 --> 00:01:34,439
aircraft flying over Lake Erie. They streamed video data to

25
00:01:34,480 --> 00:01:37,959
an optical ground station in Cleveland. From there, the data

26
00:01:37,959 --> 00:01:41,400
traveled over an Earth based network to NASA's White Sands

27
00:01:41,439 --> 00:01:46,359
test facility in New Mexico using infrared light signals. The

28
00:01:46,439 --> 00:01:49,359
data was then sent twenty two thousand miles to NASA's

29
00:01:49,439 --> 00:01:53,359
laser communications relay demonstration in orbit, which relate it to

30
00:01:53,400 --> 00:01:57,920
the ISS and back. According to doctor Daniel Rabel, principal

31
00:01:57,920 --> 00:02:02,120
investigator for the project, this achievement is a tremendous milestone.

32
00:02:02,480 --> 00:02:06,239
The success of these laser communication tests lays the groundwork

33
00:02:06,319 --> 00:02:09,879
for much anticipated features like high definition video conferencing for

34
00:02:10,000 --> 00:02:14,919
astronauts on the Moon during the Artemis missions. Continuous improvement

35
00:02:14,960 --> 00:02:17,960
of this technology during each test flight has shown that

36
00:02:18,039 --> 00:02:21,919
aeronautics testing can be more effective and cost efficient than

37
00:02:22,000 --> 00:02:26,240
ground or space testing alone. James Demmer's chief of aircraft

38
00:02:26,240 --> 00:02:29,680
Operations at Glenn, emphasize that the goal is to ensure

39
00:02:29,759 --> 00:02:32,599
new technologies don't just stay in the lab, but are

40
00:02:32,639 --> 00:02:36,479
tested and matured in real world conditions. These initiatives are

41
00:02:36,520 --> 00:02:39,280
part of a broader goal to enable high bandwidth data

42
00:02:39,280 --> 00:02:42,159
streaming from deep space, which will be crucial for future

43
00:02:42,240 --> 00:02:46,960
human missions beyond Low Earth orbit. While the current hardware

44
00:02:46,960 --> 00:02:50,759
setup may conclude its tests soon, the successful trials of

45
00:02:50,840 --> 00:02:54,719
four K video streaming from aircraft indicate a promising future

46
00:02:54,759 --> 00:02:58,000
where high definition video brings us closer to experiencing space

47
00:02:58,039 --> 00:03:01,599
missions in real time. As NASA develops advanced instruments to

48
00:03:01,639 --> 00:03:04,800
capture high definition data on the Moon and beyond, the

49
00:03:04,840 --> 00:03:08,199
capabilities of laser communications will continue to play a pivotal

50
00:03:08,280 --> 00:03:15,039
role in bringing space exploration right to our screens. New

51
00:03:15,080 --> 00:03:19,000
research using data from NASA's Messenger spacecraft has uncovered a

52
00:03:19,039 --> 00:03:23,960
surprising diamond mantle beneath Mercury's crust. Scientists have long been

53
00:03:24,000 --> 00:03:28,080
puzzled by Mercury's unique characteristics, like its very dark surface

54
00:03:28,199 --> 00:03:32,439
and dense core. By analyzing patches of graphite on its surface,

55
00:03:32,960 --> 00:03:36,599
they speculated that Mercury once had a carbon rich magma ocean,

56
00:03:37,120 --> 00:03:40,520
leading to the formation of this diamond mantle. The data

57
00:03:40,560 --> 00:03:44,599
suggests that heavy pressures and high temperatures inside Mercury caused

58
00:03:44,639 --> 00:03:47,960
carbon in the mantle to crystallize into diamonds over billions

59
00:03:48,000 --> 00:03:50,680
of years. This diamond layer could be up to ten

60
00:03:50,719 --> 00:03:54,759
miles thick, providing a completely new understanding of the planet's composition.

61
00:03:55,719 --> 00:03:59,199
This discovery not only changes our understanding of Mercury, but

62
00:03:59,319 --> 00:04:03,000
also sheds light on its rapid cooling and shortened volcanic era,

63
00:04:03,439 --> 00:04:06,479
making it starkly different from other rocky planets like Earth

64
00:04:06,560 --> 00:04:10,520
or Mars. Researchers believe that the diamond mantle might have

65
00:04:10,520 --> 00:04:14,560
played a role in the planet's fast cooling process, effectively

66
00:04:14,680 --> 00:04:19,000
ending its volcanic period much earlier than other planets. This

67
00:04:19,079 --> 00:04:23,560
finding exemplifies how unique Mercury is compared to its solar siblings,

68
00:04:23,920 --> 00:04:27,439
and opens up new pathways for understanding planetary formation and

69
00:04:27,480 --> 00:04:32,480
evolution in highly carbon rich conditions. As scientists eagerly await

70
00:04:32,560 --> 00:04:36,240
more data from future missions, including ESA's BEPY Columbo, set

71
00:04:36,240 --> 00:04:39,160
to arrive at Mercury in twenty twenty six, this diamond

72
00:04:39,240 --> 00:04:46,199
revelation continues to intrigue and inspire. NASA's ICON mission has concluded,

73
00:04:46,360 --> 00:04:49,360
but what a journey it has been. Launched in October

74
00:04:49,399 --> 00:04:55,120
twenty nineteen, ICON, or Ionospheric Connection Explorer, has provided unprecedented

75
00:04:55,160 --> 00:04:59,079
insights into the ionosphere, the outermost layer of Earth's atmosphere.

76
00:05:00,040 --> 00:05:03,319
Region nestled between fifty five miles to three hundred and

77
00:05:03,319 --> 00:05:06,800
sixty miles above our planet, is a bustling zone teeming

78
00:05:06,839 --> 00:05:10,800
with charged particles. Studying this frontier has been crucial as

79
00:05:10,839 --> 00:05:15,600
it impacts everything from satellite operations to GPS signals. One

80
00:05:15,600 --> 00:05:18,759
of the most stunning achievements of the ICON mission was

81
00:05:18,839 --> 00:05:22,839
capturing data that showcased the intricate relationship between space weather

82
00:05:23,240 --> 00:05:27,680
and Earth's weather. A mesmerizing feature called air glow was

83
00:05:27,759 --> 00:05:34,199
extensively observed, helping scientists decode the ionosphere's density, composition, and structure.

84
00:05:34,639 --> 00:05:38,519
Unlike the Aurora borealis, which paints the polar skies, air

85
00:05:38,600 --> 00:05:42,079
glow is a subtle, world spanning phenomenon created by similar processes.

86
00:05:42,560 --> 00:05:45,959
But that's not all. ICON provided the scientific community with

87
00:05:46,000 --> 00:05:50,120
its first ever concrete observations of the long theorized ionospheric dynamo.

88
00:05:50,720 --> 00:05:54,399
This dynamic system of terrestrial winds and space weather interactions

89
00:05:54,839 --> 00:05:59,720
generates complex electric and magnetic fields. Icon's measurements revealed how

90
00:05:59,800 --> 00:06:03,800
unp predictable terrestrial winds move plasma around the ionosphere, causing

91
00:06:03,879 --> 00:06:06,519
charged particles to either shoot out into space or plummet

92
00:06:06,519 --> 00:06:10,079
towards Earth. This discovery has been nothing short of transformational.

93
00:06:11,000 --> 00:06:13,959
The mission also captured how external events such as volcanic

94
00:06:14,079 --> 00:06:18,519
eruptions influenced the ionosphere. The twenty twenty two Hunga Tonga

95
00:06:18,519 --> 00:06:22,000
Hangaha up high eruption, for instance, disrupted electrical currents in

96
00:06:22,040 --> 00:06:26,120
this charged layer. Icon's instruments were able to directly observe

97
00:06:26,160 --> 00:06:29,160
the speed of this volcanic plume and its far reaching

98
00:06:29,199 --> 00:06:33,319
impacts on ionospheric structures. However, as with all great missions,

99
00:06:33,600 --> 00:06:36,600
there came a time to say goodbye. Communication with the

100
00:06:36,879 --> 00:06:40,439
ICON spacecraft was lost in November twenty twenty two, and

101
00:06:40,519 --> 00:06:44,959
despite best efforts, contact could not be re established. While

102
00:06:44,959 --> 00:06:49,000
the mission officially ended, its legacy endures the wealth of

103
00:06:49,079 --> 00:06:52,600
data collected will continue to benefit space and atmospheric science

104
00:06:52,680 --> 00:06:55,839
for years to come. Icon has indeed lived up to

105
00:06:55,879 --> 00:06:59,519
its name, making iconic contributions to our understanding of the

106
00:06:59,519 --> 00:07:05,959
boundary between Earth and space. The James Webb Space Telescope

107
00:07:05,959 --> 00:07:10,439
has achieved another groundbreaking milestone by successfully imaging a super

108
00:07:10,519 --> 00:07:15,480
jupiter in the nearby Epsilon INDIE system. This monumental discovery

109
00:07:15,600 --> 00:07:18,680
is setting the stage for a new era of exoplanet research,

110
00:07:19,160 --> 00:07:22,360
allowing scientists to study colder gas giant planets in much

111
00:07:22,399 --> 00:07:27,319
more detail than ever before. Epsilon INDIPS and D for short,

112
00:07:27,639 --> 00:07:30,319
is a nearby triple star system located just twelve light

113
00:07:30,399 --> 00:07:34,240
years from Earth. The newly imaged planet designated as epsend

114
00:07:34,279 --> 00:07:38,720
ab orbits the primary star of the system. Previous studies

115
00:07:38,720 --> 00:07:41,879
had identified this planet, but with the data from JWST,

116
00:07:42,399 --> 00:07:45,720
scientists were able to correct earlier misconceptions about its mass

117
00:07:45,800 --> 00:07:48,920
and orbital path. It turns out this super jupiter is

118
00:07:48,959 --> 00:07:51,879
about six times the mass of Jupiter and follows an

119
00:07:51,920 --> 00:07:55,639
elliptical orbit ranging from twenty to forty astronomical units from

120
00:07:55,680 --> 00:07:59,120
its star. One of the most exciting aspects of this

121
00:07:59,160 --> 00:08:02,800
discovery is that it's the first time a relatively cold

122
00:08:03,040 --> 00:08:07,519
gas giant planet has been imaged directly, rather than through

123
00:08:07,560 --> 00:08:12,920
indirect methods like transits or radial velocity measurements. By capturing

124
00:08:12,959 --> 00:08:17,439
direct images and analyzing the planet's spectra, researchers can study

125
00:08:17,480 --> 00:08:22,560
its atmosphere and monitor its evolution, comparing it to computational models.

126
00:08:23,160 --> 00:08:27,199
This advances our understanding of planet formation processes and the

127
00:08:27,279 --> 00:08:31,839
late stages of planetary system development. The EP's end AB, planet,

128
00:08:32,000 --> 00:08:35,200
cooler than the gas giants previously studied, showed up in

129
00:08:35,279 --> 00:08:39,480
JWST's mid infrared instrument MIRRY images as a bright dot.

130
00:08:40,000 --> 00:08:43,799
To achieve this, JWST used a coronagraph that blocks out

131
00:08:43,840 --> 00:08:47,120
the blinding light of the host star, making it possible

132
00:08:47,159 --> 00:08:49,919
to see the faint light emitted by the planet itself.

133
00:08:50,720 --> 00:08:53,639
This method opens new doors to studying gas giants that

134
00:08:53,679 --> 00:08:56,279
are otherwise difficult to detect due to their distance from

135
00:08:56,320 --> 00:09:01,080
their parent stars. The data also revealed some intrigue characteristics

136
00:09:01,120 --> 00:09:05,759
about PSI and d AB's atmospheric composition, suggesting substantial amounts

137
00:09:05,759 --> 00:09:10,120
of heavy elements like carbon. However, further research is necessary

138
00:09:10,159 --> 00:09:14,720
to draw definitive conclusions. In future observations, scientists aim to

139
00:09:14,759 --> 00:09:18,440
obtain detailed spectra that will provide in depth information about

140
00:09:18,440 --> 00:09:22,519
the planet's climate and chemical composition. This discovery acts as

141
00:09:22,559 --> 00:09:26,279
a stepping stone for hunting more cold gas giants. Helping

142
00:09:26,320 --> 00:09:28,960
to refine our theories on how such planets form and

143
00:09:29,000 --> 00:09:32,279
evolve in their mature stages. So keep your eyes on

144
00:09:32,320 --> 00:09:34,799
the stars and stay tuned to Astronomy Daily for more

145
00:09:34,799 --> 00:09:38,759
fascinating insights as we continue to explore the ever expanding universe.
