1
00:00:00.160 --> 00:00:04.000
Hello, space enthusiasts. Today we have an absolutely packed show

2
00:00:04.040 --> 00:00:07.679
with some incredible developments from across the cosmic frontier, from

3
00:00:07.759 --> 00:00:11.439
groundbreaking solar research during the recent eclipse to fascinating discoveries

4
00:00:11.439 --> 00:00:15.279
about distant worlds. We're covering it all. We'll dive into

5
00:00:15.320 --> 00:00:18.879
how scientists use the spectacular North American solar eclipse to

6
00:00:19.000 --> 00:00:22.120
unlock new secrets about our Son's corona, and we'll look

7
00:00:22.160 --> 00:00:24.879
ahead to an exciting Christmas Eve mission that will take

8
00:00:24.960 --> 00:00:28.199
us closer to our star than ever before. We've also

9
00:00:28.239 --> 00:00:30.800
got some intriguing news about organic compounds found on the

10
00:00:30.879 --> 00:00:33.960
Dwarf Planet series that could have major implications for the

11
00:00:34.000 --> 00:00:37.399
search for life. Plus a concerning incident with a satellite

12
00:00:37.399 --> 00:00:41.679
breakup that's raising important questions about space security. And don't

13
00:00:41.679 --> 00:00:45.640
miss our story about an extraordinary exoplanet that's literally leaving

14
00:00:45.640 --> 00:00:48.679
a trail through space. It's the kind of discovery that

15
00:00:48.719 --> 00:00:51.920
reminds us just how weird and wonderful our universe can be.

16
00:00:52.799 --> 00:00:55.399
We've got a lot to cover, so let's get started.

17
00:00:56.399 --> 00:01:00.439
Scientists have been making remarkable discoveries about our Son thanks

18
00:01:00.479 --> 00:01:03.600
to the recent solar eclipse that swept across North America,

19
00:01:04.239 --> 00:01:07.840
When the Moon perfectly blocked out the Sun's blindingly bright surface,

20
00:01:08.519 --> 00:01:12.359
researchers got a rare opportunity to study the mysterious corona,

21
00:01:13.040 --> 00:01:16.920
the Sun's outer atmosphere that's normally impossible to observe from Earth.

22
00:01:17.439 --> 00:01:21.640
The eclipse sparked multiple citizen science initiatives, including an ambitious

23
00:01:21.640 --> 00:01:25.719
project called Citizen Kate twenty twenty four, which deployed thirty

24
00:01:25.719 --> 00:01:29.319
five telescopes from Texas all the way to Maine. By

25
00:01:29.359 --> 00:01:33.680
combining data from these stations, researchers are creating an unprecedented

26
00:01:33.760 --> 00:01:37.840
sixty minute movie showing how the corona changed throughout the eclipse.

27
00:01:38.439 --> 00:01:41.120
What makes this project even more special is how it

28
00:01:41.159 --> 00:01:44.120
brought together people from all walks of life, from middle

29
00:01:44.120 --> 00:01:48.239
school students to retirees, to conduct cutting edge solar research.

30
00:01:49.239 --> 00:01:54.439
Another fascinating project involved over six thousand amateur radio operators

31
00:01:54.439 --> 00:01:58.400
across the continent. By tracking how radio signals behaved during

32
00:01:58.439 --> 00:02:02.640
the eclipse, they helped map changes in Earth's ionosphere, the

33
00:02:02.719 --> 00:02:06.480
electrically charged layer of our upper atmosphere that's critical for

34
00:02:06.519 --> 00:02:11.240
satellite communications. The sudden absence of sunlight during the eclipse

35
00:02:11.680 --> 00:02:16.080
created unique conditions that helped scientists better understand how solar

36
00:02:16.159 --> 00:02:21.599
radiation affects our planet's atmospheric layers. Weather balloons launched during

37
00:02:21.599 --> 00:02:26.080
the eclipse revealed something equally intriguing. The Moon's shadow actually

38
00:02:26.120 --> 00:02:29.800
generates waves in our atmosphere, similar to ripples in a pond.

39
00:02:30.479 --> 00:02:34.080
These atmospheric waves could help improve our weather forecasting models

40
00:02:34.400 --> 00:02:37.560
by showing us how different layers of our atmosphere interact.

41
00:02:38.520 --> 00:02:41.159
All of this research is about to get even more exciting.

42
00:02:42.280 --> 00:02:45.360
On Christmas Eve, NASA's Parker Solar Probe will make its

43
00:02:45.400 --> 00:02:48.800
closest approach yet to the Sun, diving to within just

44
00:02:48.840 --> 00:02:52.000
six point two one million kilometers of our star's surface.

45
00:02:52.719 --> 00:02:54.080
This will put it right in the middle of the

46
00:02:54.120 --> 00:02:58.599
corona regions that scientists observe during the eclipse. By combining

47
00:02:58.599 --> 00:03:02.639
these different perspectives from Earth based eclipse observations to direct

48
00:03:02.639 --> 00:03:06.520
measurements from Parker, researchers are building a more complete picture

49
00:03:06.520 --> 00:03:08.879
of how our Sun works and how it influences life

50
00:03:08.919 --> 00:03:12.319
here on Earth. As one NASA scientists put it, it's

51
00:03:12.360 --> 00:03:14.879
like different people trying to describe an elephant by touching

52
00:03:14.879 --> 00:03:18.599
different parts. The eclipse gives us one view of the corona,

53
00:03:19.039 --> 00:03:23.759
while Parker provides another perspective. By flying right through it together,

54
00:03:24.319 --> 00:03:27.240
they're helping us solve the complex puzzle of solar physics

55
00:03:27.599 --> 00:03:32.639
and its effects on our planet. Next up, exciting discoveries

56
00:03:32.680 --> 00:03:36.360
are emerging from NASA's Dawn mission to Series, the largest

57
00:03:36.400 --> 00:03:40.319
object in the asteroid belt. Scientists have identified eleven new

58
00:03:40.319 --> 00:03:45.120
regions containing organic compounds on this fascinating dwarf planet, suggesting

59
00:03:45.159 --> 00:03:49.719
the presence of vast internal reservoirs of organic materials. This

60
00:03:49.919 --> 00:03:54.280
finding builds upon the initial twenty seventeen discovery of organic

61
00:03:54.360 --> 00:03:59.759
compounds near ceres Ernutete Crater. What makes this discovery p

62
00:03:59.840 --> 00:04:03.719
ticularly intriguing is that these organic materials appear to be

63
00:04:03.800 --> 00:04:07.919
native to Series, rather than delivered by comets or asteroids

64
00:04:08.240 --> 00:04:13.280
as previously thought. This indicates that Series possesses internal energy

65
00:04:13.319 --> 00:04:18.040
sources potentially capable of supporting biological processes, making it an

66
00:04:18.079 --> 00:04:22.839
even more significant target for astrobiological studies. At over nine

67
00:04:22.959 --> 00:04:26.759
hundred and thirty kilometers in diameter, Series stands out as

68
00:04:26.800 --> 00:04:29.399
the most water rich body in the Inner Solar System

69
00:04:29.439 --> 00:04:32.920
after Earth. The presence of both water ice, and possibly

70
00:04:32.959 --> 00:04:36.199
liquid water beneath its surface places it among the ocean

71
00:04:36.240 --> 00:04:40.199
worlds that could harbour conditions suitable for life. This combination

72
00:04:40.279 --> 00:04:43.879
of water and organic compounds makes Series an increasingly compelling

73
00:04:43.920 --> 00:04:48.720
destination for future space exploration. The research team employed sophisticated

74
00:04:48.720 --> 00:04:52.480
analysis techniques to make these discoveries. They first characterize the

75
00:04:52.519 --> 00:04:57.480
compounds in the Airnutet crater, then systematically scanned Series' entire

76
00:04:57.519 --> 00:05:03.000
surface using high resolution images from the Dawn spacecraft. Most intriguingly,

77
00:05:03.399 --> 00:05:07.279
they found a particularly strong signature of organic materials in

78
00:05:07.360 --> 00:05:10.800
the region between the Orvara and yellow Da basins, where

79
00:05:10.879 --> 00:05:15.639
violent impacts had excavated material from deep within Series. Laboratory

80
00:05:15.680 --> 00:05:19.800
experiments supporting this research have shown that organic compounds degrade

81
00:05:19.800 --> 00:05:24.319
more rapidly under solar radiation than previously thought. Given the

82
00:05:24.399 --> 00:05:29.000
quantities of organic materials detected and their observed degradation levels,

83
00:05:29.120 --> 00:05:33.199
scientists believe there must be substantial reservoirs of organic compounds

84
00:05:33.240 --> 00:05:37.600
beneath Series' surface. These findings have significant implications for our

85
00:05:37.680 --> 00:05:40.680
understanding of the early Solar System and the potential for

86
00:05:40.759 --> 00:05:44.360
life supporting environments beyond Earth. As a remnant from our

87
00:05:44.399 --> 00:05:48.399
Solar system's formation four point six billion years ago, Series

88
00:05:48.439 --> 00:05:52.160
could provide crucial insights into the distribution of organic materials

89
00:05:52.199 --> 00:05:56.600
during planetary formation. Looking to the future, series might even

90
00:05:56.639 --> 00:05:59.800
serve as a strategic stopover point for deep space missions,

91
00:06:00.319 --> 00:06:06.079
offering valuable resources for space exploration beyond Mars. A concerning

92
00:06:06.120 --> 00:06:08.720
development in orbital space has emerged with the breakup of

93
00:06:08.759 --> 00:06:13.519
Intelsat thirty three E in geostationary orbit. Space tracking company

94
00:06:13.600 --> 00:06:17.439
Exoanalytics Solutions has identified more than seven hundred pieces of

95
00:06:17.480 --> 00:06:21.439
debris from this incident, which occurred on October nineteenth. The

96
00:06:21.519 --> 00:06:25.040
fragments ranged dramatically in size, from pieces as small as

97
00:06:25.040 --> 00:06:29.199
softballs to others as large as car doors. This event

98
00:06:29.240 --> 00:06:34.240
has raised significant concerns about space security. Exoanalytics Solutions chief

99
00:06:34.240 --> 00:06:37.920
growth officer warns that such breakups could potentially be exploited

100
00:06:38.000 --> 00:06:42.439
by adversaries, as the resulting debris cloud creates substantial noise

101
00:06:42.519 --> 00:06:46.120
in tracking systems that could mask other activities in geostationary orbit.

102
00:06:47.160 --> 00:06:50.079
The incident marks the second failure in Boeing series of

103
00:06:50.160 --> 00:06:54.199
epic aang high throughput satellites built for Intelsat. The First

104
00:06:54.199 --> 00:06:58.160
satellite in the series, Intelsat twenty nine E, was lost

105
00:06:58.160 --> 00:07:01.800
in twenty nineteen following what investigators determined was either a

106
00:07:01.839 --> 00:07:06.319
meteoroid impact or a wiring flaw. Boeing is currently investigating

107
00:07:06.360 --> 00:07:09.800
the cause of this latest breakup. While the immediate danger

108
00:07:09.800 --> 00:07:13.319
from the debris has significantly decreased over recent months, the

109
00:07:13.360 --> 00:07:17.639
incident highlights growing challenges in the increasingly contested space domain.

110
00:07:18.360 --> 00:07:23.279
Exoanalytics Solutions reports that collision alerts, which initially spiked to

111
00:07:23.360 --> 00:07:27.360
four times normal levels following the breakup, have now stabilized

112
00:07:27.519 --> 00:07:32.519
to typical frequencies. This event coincides with observations of increasing

113
00:07:32.600 --> 00:07:38.279
Chinese activities in geostationary orbit, including routine satellite maneuvers and

114
00:07:38.319 --> 00:07:42.319
close up inspections of other satellites. Space tracking experts have

115
00:07:42.360 --> 00:07:46.000
noted China's expanding presence in space, with their satellite fleet

116
00:07:46.040 --> 00:07:48.759
growing from just thirty six and twenty ten to more

117
00:07:48.759 --> 00:07:51.879
than one thousand to day, adding another layer of complexity

118
00:07:51.879 --> 00:07:56.439
to space domain awareness and security concerns. Now a quick

119
00:07:56.480 --> 00:08:00.319
but significant update. Rocket Lab has recently unveiled the purpose

120
00:08:00.360 --> 00:08:04.000
behind their secretive November launch, confirming it was a hypersonic

121
00:08:04.040 --> 00:08:08.319
technology test for the US Department of Defense. The suborbital mission,

122
00:08:08.439 --> 00:08:11.800
which took place on November twenty fourth from Virginia's Wallops

123
00:08:11.800 --> 00:08:16.079
Island utilized their HASTE Vehicle, a modified version of their

124
00:08:16.120 --> 00:08:21.040
Electron rocket designed specifically for suborbital flights. What makes this

125
00:08:21.120 --> 00:08:24.000
mission particularly remarkable is that it was a part of

126
00:08:24.040 --> 00:08:28.040
an unprecedented double header for rocket Lab. Less than twenty

127
00:08:28.040 --> 00:08:32.080
two hours after the military test, they successfully launched another

128
00:08:32.120 --> 00:08:35.960
mission from a completely different hemisphere, deploying five Internet of

129
00:08:36.039 --> 00:08:39.919
Thing satellites for French company Qineis. The military test flight

130
00:08:40.000 --> 00:08:43.759
was conducted under the Multi Service Advanced Capability Hypersonics Test

131
00:08:43.759 --> 00:08:47.840
Bed Project known as Match TB. This initiative aims to

132
00:08:47.879 --> 00:08:51.480
expand hypersonic flight testing capabilities for the United States Military.

133
00:08:51.919 --> 00:08:54.799
Rocket Lab not only provided the launch platform, but also

134
00:08:54.919 --> 00:08:58.879
designed and manufactured the experimental hypersonic instrumentation for the mission,

135
00:08:59.159 --> 00:09:03.440
completing this on an accelerated timeline. This mission marked only

136
00:09:03.480 --> 00:09:06.519
the second flight of the Haste vehicle, with its debut

137
00:09:06.600 --> 00:09:09.519
launch occurring in June twenty twenty three from the same

138
00:09:09.600 --> 00:09:13.519
launch facility. The subsequent orbital launch the next day proved

139
00:09:13.600 --> 00:09:16.879
equally significant for rocket Lab, as it pushed their total

140
00:09:16.960 --> 00:09:20.960
satellite deployment count past the two hundred mark, reaching two

141
00:09:21.039 --> 00:09:24.919
hundred and three satellites launched aboard their electron rocket across

142
00:09:25.000 --> 00:09:29.360
fifty four successful missions, with thirteen of those launches occurring

143
00:09:29.480 --> 00:09:34.879
this year alone. Meanwhile, further out in space, in an

144
00:09:34.879 --> 00:09:39.240
intriguing astronomical discovery, scientists have identified something quite unusual about

145
00:09:39.279 --> 00:09:43.679
the exoplanet WASP sixty nine BEE. It's sporting a massive

146
00:09:43.720 --> 00:09:46.039
tail of gas that stretches more than three hundred fifty

147
00:09:46.080 --> 00:09:49.679
thousand miles behind it. This remarkable feature is actually the

148
00:09:49.720 --> 00:09:53.759
planet's atmosphere being slowly stripped away into space, creating a

149
00:09:53.759 --> 00:09:56.279
comet like tail that's more than seven and a half

150
00:09:56.320 --> 00:10:01.039
times the planet's radius. The process creating this celestial spectacle

151
00:10:01.120 --> 00:10:04.720
is fascinating. WASP sixty nine B is what we call

152
00:10:04.759 --> 00:10:08.320
a hot Jupiter, orbiting extremely close to its host star.

153
00:10:09.039 --> 00:10:12.360
The intense stellar radiation heats the planet's outer atmosphere so

154
00:10:12.480 --> 00:10:15.879
much that lightweight gases like hydrogen and helium are literally

155
00:10:15.919 --> 00:10:19.639
being launched into space. But here's where it gets really interesting.

156
00:10:20.360 --> 00:10:23.960
Instead of escaping uniformly around the planet, these gases are

157
00:10:24.000 --> 00:10:26.440
swept into a tail by the stellar wind from the

158
00:10:26.480 --> 00:10:31.039
planet's star, much like how a windsock behaves in a breeze.

159
00:10:31.159 --> 00:10:33.600
While losing two hundred thousand tons of gas per second

160
00:10:33.679 --> 00:10:37.480
might sound catastrophic, the planet is actually losing its atmosphere

161
00:10:37.600 --> 00:10:40.840
very gradually. To put this in perspective, it takes about

162
00:10:40.879 --> 00:10:43.480
a billion years for WASP sixty nine B to lose

163
00:10:43.480 --> 00:10:45.759
an amount of material equivalent to the mass of Earth.

164
00:10:46.519 --> 00:10:49.519
Given that this Solar system is around seven billion years old,

165
00:10:49.799 --> 00:10:52.679
the planet has likely lost the equivalent of seven earths

166
00:10:52.679 --> 00:10:56.480
worth of mass over its lifetime. The tail's exact length

167
00:10:56.559 --> 00:11:00.159
remains a mystery, as researchers had to end their observation

168
00:11:00.320 --> 00:11:05.200
before the tale's signal completely disappeared. Even more intriguingly, the

169
00:11:05.279 --> 00:11:08.679
tale's size and shape can change over time as the

170
00:11:08.720 --> 00:11:12.519
stellar wind fluctuates, making it a dynamic feature that could

171
00:11:12.519 --> 00:11:16.799
help scientists better understand the complex relationship between stars and

172
00:11:16.840 --> 00:11:21.200
their planets. This discovery isn't just a cosmic curiosity. It's

173
00:11:21.240 --> 00:11:25.519
providing valuable insights into how planetary atmospheres interact with their

174
00:11:25.559 --> 00:11:30.759
host stars and evolve over time. Well. That brings us

175
00:11:30.759 --> 00:11:34.279
to the end of today's fascinating journey through space. This

176
00:11:34.399 --> 00:11:36.519
is Anna and I want to thank you for joining
