00:00:00.200 --> 00:00:03.439
Welcome to Astronomy Daily, your source for the latest space

2
00:00:03.480 --> 00:00:06.799
and astronomy news. I'm Anna and today we've got a

3
00:00:06.799 --> 00:00:10.880
fascinating lineup of stories covering everything from European space developments

4
00:00:11.199 --> 00:00:14.759
to lunar discoveries and the mysteries of black holes. In

5
00:00:14.800 --> 00:00:18.120
today's episode, we'll explore major developments in europe space industry,

6
00:00:18.719 --> 00:00:22.399
dive into a groundbreaking new constellation resource, examine surprising findings

7
00:00:22.399 --> 00:00:26.039
from China's Changey six Moon mission, look at a possible

8
00:00:26.039 --> 00:00:29.640
solution to a long standing black hole paradox, and discuss

9
00:00:29.719 --> 00:00:33.200
an intriguing proposal for satellite defense in space. So let's

10
00:00:33.200 --> 00:00:37.679
get underway. The European space industry has been making remarkable

11
00:00:37.719 --> 00:00:41.439
progress this year, with several key developments reshaping the continent's

12
00:00:41.479 --> 00:00:45.520
launch capabilities. Ariana Space kicked off twenty twenty four with

13
00:00:45.600 --> 00:00:49.439
a milestone achievement the successful maiden launch of their Ariani

14
00:00:49.479 --> 00:00:52.799
six rocket from French Guiana in July. This marks a

15
00:00:52.799 --> 00:00:56.079
crucial transition as Ariani six takes over from its predecessor,

16
00:00:56.240 --> 00:01:00.560
the Ariani five, as Europe's primary heavy lift vehicle. The

17
00:01:00.640 --> 00:01:04.719
Vega program has also seen significant advancement after nearly two

18
00:01:04.799 --> 00:01:08.000
years of standing down, the VEGAC rocket made a triumphant

19
00:01:08.040 --> 00:01:11.840
return to flight, successfully deploying the Sentinel one CEA Earth

20
00:01:11.920 --> 00:01:16.400
observation satellite. This success has led to ambitious expansion plans,

21
00:01:16.799 --> 00:01:20.480
with Esay signing new contracts with Avio to increase Vegacy's

22
00:01:20.560 --> 00:01:24.959
flight frequency and accelerate development of its successor, the Vega E.

23
00:01:25.640 --> 00:01:29.159
Several emerging players are bringing fresh innovation to the European

24
00:01:29.200 --> 00:01:33.799
space sector. German company High Impulse is pioneering hybrid rocket

25
00:01:33.799 --> 00:01:38.640
technology using an environmentally friendly combination of paraffin based fuel

26
00:01:38.719 --> 00:01:42.439
and liquid oxygen. Their successful launch of the SR seventy

27
00:01:42.439 --> 00:01:45.239
five sounding rocket earlier this year has paved the way

28
00:01:45.239 --> 00:01:49.840
for their orbital launcher development. Meanwhile, UK based Orbex has

29
00:01:49.840 --> 00:01:53.079
made strategic moves by announcing plans to relocate their launch

30
00:01:53.079 --> 00:01:57.200
operations to sax Afoord Spaceport in Shetland, streamlining their path

31
00:01:57.239 --> 00:01:59.959
to achieving first flight of their Proxima rocket in twenty two.

32
00:02:01.159 --> 00:02:05.079
This reorganization allows them to focus resources on developing their

33
00:02:05.079 --> 00:02:08.560
innovative medium class launcher. The industry is seeing a clear

34
00:02:08.599 --> 00:02:12.520
trend toward reusability, with Spanish company PLD Space leading the

35
00:02:12.599 --> 00:02:17.319
charge following their successful MUA one test flight. They've unveiled

36
00:02:17.360 --> 00:02:21.120
plans for a partially reusable Mura five rocket and announced

37
00:02:21.120 --> 00:02:25.199
an ambitious new family of launchers called Mura Next, setting

38
00:02:25.280 --> 00:02:28.319
the stage for Europe's entry into the reusable rocket market.

39
00:02:29.759 --> 00:02:32.680
Next up a gift for you this holiday season for

40
00:02:32.759 --> 00:02:36.280
stargazers and astronomers alike. An exciting new resource has just

41
00:02:36.319 --> 00:02:40.240
been unveiled through a collaboration between NSF's nor Lab and

42
00:02:40.280 --> 00:02:45.479
the European Space Agency. This comprehensive digital collection brings together stunning,

43
00:02:45.599 --> 00:02:50.560
high resolution images of all eighty eight officially recognized constellations

44
00:02:50.919 --> 00:02:54.000
that fill our night sky. At the heart of this

45
00:02:54.120 --> 00:03:00.439
collection are spectacular photographs captured by German astrophotographer Eckhardslawik using

46
00:03:00.479 --> 00:03:04.560
an innovative technique that combines filtered and unfiltered exposures. These

47
00:03:04.599 --> 00:03:08.360
images beautifully showcase the natural colors of the stars while

48
00:03:08.400 --> 00:03:12.759
maintaining remarkable clarity and detail. The entire collection has been

49
00:03:12.800 --> 00:03:16.840
seamlessly stitched together into an interactive all sky map that

50
00:03:16.960 --> 00:03:21.199
allows users to explore the celestial sphere in unprecedented detail.

51
00:03:22.199 --> 00:03:25.960
What makes this resource particularly valuable is its educational depth.

52
00:03:26.599 --> 00:03:30.960
Each constellation entry comes with extensive background information, including its

53
00:03:31.080 --> 00:03:35.520
historical origins and mythology. Traditional stick figure patterns are provided

54
00:03:35.599 --> 00:03:39.280
alongside practical finder charts to help observers locate these star

55
00:03:39.360 --> 00:03:43.120
patterns in the night sky. The collection also features detailed

56
00:03:43.120 --> 00:03:48.000
information about prominent deep sky objects within each constellation's boundaries.

57
00:03:48.599 --> 00:03:52.759
This project addresses a common challenge for astronomers, the fact

58
00:03:52.800 --> 00:03:55.439
that no single location on Earth can view all eighty

59
00:03:55.479 --> 00:04:00.280
eight constellations. For instance, observers at mid northern latitudes miss

60
00:04:00.280 --> 00:04:04.159
out on roughly fourteen complete constellations and get only partial

61
00:04:04.280 --> 00:04:07.759
views of another fifteen throughout the year. This digital resource

62
00:04:07.800 --> 00:04:11.639
finally brings the entire celestial sphere within reach of anyone

63
00:04:11.759 --> 00:04:15.120
with an Internet connection. The timing of this release is

64
00:04:15.159 --> 00:04:19.160
particularly significant, as it comes exactly one hundred years after

65
00:04:19.199 --> 00:04:23.879
the International Astronomical Union first standardized the eighty eight constellations

66
00:04:23.920 --> 00:04:27.839
we recognize today. This modern digital at LISS serves as

67
00:04:27.839 --> 00:04:30.639
a fitting tribute to that historic achievement while making these

68
00:04:30.680 --> 00:04:34.879
celestial patterns accessible to a new generation of skywatchers. If

69
00:04:34.920 --> 00:04:36.920
you'd like to check it out, I'll leave a link

70
00:04:36.959 --> 00:04:41.079
in the show notes for you. Remarkable findings from China's

71
00:04:41.120 --> 00:04:44.959
Changa six lunar mission are reshaping our understanding of the

72
00:04:45.000 --> 00:04:49.879
Moon's magnetic history. Scientists analyzing basalt samples from the Moon's

73
00:04:49.879 --> 00:04:53.439
far side have discovered evidence of an unexpected surge in

74
00:04:53.560 --> 00:04:57.519
lunar magnetic field strength approximately two point eight billion years ago.

75
00:04:58.199 --> 00:05:02.680
This discovery is particularly significant because it challenges our previous

76
00:05:02.680 --> 00:05:07.399
assumptions about the Moon's magnetic evolution. The samples, which represent

77
00:05:07.439 --> 00:05:11.399
the first ever palaeomagnetic data from the lunar far side,

78
00:05:11.920 --> 00:05:15.399
show magnetic field strengths ranging from five to twenty one

79
00:05:15.959 --> 00:05:20.879
microteslas during this period. To put this in perspective, that's

80
00:05:20.879 --> 00:05:24.639
substantially stronger than what scientists previously believed possible at this

81
00:05:24.720 --> 00:05:28.120
point in lunar history. What makes this finding so intriguing

82
00:05:28.519 --> 00:05:32.360
is its timing. Prior to this discovery, researchers thought the

83
00:05:32.360 --> 00:05:35.759
Moon's magnetic dynamo had entered a quiet phase around three

84
00:05:35.839 --> 00:05:39.199
point one billion years ago. Instead, these samples reveal that

85
00:05:39.240 --> 00:05:43.519
the Moon's interior remained remarkably active and dynamic well into

86
00:05:43.560 --> 00:05:47.399
its middle years. The research team, led by Professor Rixiang

87
00:05:47.480 --> 00:05:51.439
Ju at the Chinese Academy of Sciences, suggests this magnetic

88
00:05:51.519 --> 00:05:56.319
resurgence might have been driven by several mechanisms. One possibility

89
00:05:56.319 --> 00:06:00.240
involves a basal magma ocean at the Moon's core mantle boundary.

90
00:06:00.959 --> 00:06:06.120
Another theory points to processional forces, while core crystallization processes

91
00:06:06.399 --> 00:06:09.319
might have also played a role. These findings don't just

92
00:06:09.360 --> 00:06:12.680
tell us about the Moon's magnetic field. They provide crucial

93
00:06:12.720 --> 00:06:16.800
insights into the thermal and geological evolution of our celestial neighbor.

94
00:06:17.560 --> 00:06:20.759
The data suggests that the Moon's deep interior remained hot

95
00:06:20.879 --> 00:06:24.920
and geologically active far longer than previously thought, forcing us

96
00:06:24.920 --> 00:06:29.079
to reconsider our models of lunar evolution. This breakthrough also

97
00:06:29.199 --> 00:06:31.920
highlights the importance of sampling different regions of the Moon.

98
00:06:32.720 --> 00:06:36.160
Until now, our understanding has been based primarily on samples

99
00:06:36.199 --> 00:06:39.399
from the near side. These far side samples are giving

100
00:06:39.480 --> 00:06:42.319
us a more complete picture of the Moon's complex history

101
00:06:42.839 --> 00:06:45.959
and demonstrating that our satellite's evolution was far more dynamic

102
00:06:45.959 --> 00:06:50.560
than we once believed. A fascinating new study may have

103
00:06:50.639 --> 00:06:53.639
uncovered a solution to one of the most perplexing problems

104
00:06:53.680 --> 00:06:57.759
in modern physics, the black hole information paradox that even

105
00:06:57.800 --> 00:07:01.639
stumped the brilliant Stephen Hawking. This paradox emerges from the

106
00:07:01.680 --> 00:07:06.319
apparent contradiction between quantum mechanics and our understanding of black holes.

107
00:07:07.160 --> 00:07:11.000
Back in nineteen seventy six, Hawking made the groundbreaking discovery

108
00:07:11.000 --> 00:07:14.879
that black holes aren't completely black. They actually emit tiny

109
00:07:14.879 --> 00:07:19.319
amounts of radiation over extremely long periods. This radiation can

110
00:07:19.360 --> 00:07:23.639
cause black holes to eventually evaporate and disappear. But this

111
00:07:23.680 --> 00:07:26.959
creates a major problem. What happens to all the information

112
00:07:27.000 --> 00:07:30.160
about the matter that fell into the black hole. According

113
00:07:30.160 --> 00:07:34.839
to quantum mechanics, this information can't simply vanish. Now, researchers

114
00:07:34.879 --> 00:07:38.600
at Caltech have proposed an intriguing solution involving quantum connections

115
00:07:38.639 --> 00:07:42.279
between a black hole's interior and exterior. They suggest that,

116
00:07:42.319 --> 00:07:46.040
through a phenomenon called nonviolent non locality, the inside of

117
00:07:46.040 --> 00:07:48.839
a black hole maintains subtle quantum links with the space

118
00:07:48.879 --> 00:07:52.560
around it, similar to what Einstein famously called spooky action.

119
00:07:52.720 --> 00:07:57.199
At a distance, these quantum connections would create tiny ripples

120
00:07:57.240 --> 00:08:01.319
in the fabric of space time surrounding the black While

121
00:08:01.360 --> 00:08:06.079
these perturbations would be incredibly small, they wouldn't be random. Instead,

122
00:08:06.560 --> 00:08:10.600
they would carry encoded information about everything inside the black hole.

123
00:08:11.079 --> 00:08:14.399
This means that when a black hole finally evaporates, all

124
00:08:14.439 --> 00:08:17.879
that information would still exist in the surrounding spacetime fabric.

125
00:08:18.439 --> 00:08:21.120
The exciting part is that we might actually be able

126
00:08:21.160 --> 00:08:25.360
to detect evidence of this effect. The research team predicts

127
00:08:25.399 --> 00:08:30.000
these quantum correlations would leave distinct signatures in gravitational waves

128
00:08:30.040 --> 00:08:34.600
produced when black holes merge. While our current detectors aren't

129
00:08:34.639 --> 00:08:37.840
quite sensitive enough to pick up these subtle signals, the

130
00:08:37.879 --> 00:08:42.559
next generation of gravitational wave observatories could potentially spot them.

131
00:08:42.919 --> 00:08:46.519
If confirmed, this would not only resolve the information paradox,

132
00:08:46.720 --> 00:08:50.960
but also demonstrate a deep connection between gravity and quantum mechanics,

133
00:08:51.799 --> 00:08:55.120
two fundamental theories that we've struggled to reconcile for nearly

134
00:08:55.159 --> 00:08:58.759
a century. The researchers are now working on more detailed

135
00:08:58.759 --> 00:09:02.639
models to predict exactactly what these gravitational wave signatures should

136
00:09:02.679 --> 00:09:07.440
look like. In an intriguing development for space security, United

137
00:09:07.480 --> 00:09:10.360
Launch Alliance is looking to expand the capabilities of their

138
00:09:10.480 --> 00:09:15.480
Vulcan Centaur rocket beyond just launch operations. CEO Tory Bruno

139
00:09:15.600 --> 00:09:19.039
recently unveiled plans to upgrade the rocket's upper stage, known

140
00:09:19.080 --> 00:09:23.360
as Centaur, into a rapid response space defense system. The

141
00:09:23.399 --> 00:09:27.200
proposed enhancement would transform Centaur into what Bruno calls a

142
00:09:27.279 --> 00:09:31.759
space interceptor capable of quickly responding to threats against US

143
00:09:31.840 --> 00:09:35.440
Space Force satellites. This comes at a crucial time when

144
00:09:35.480 --> 00:09:39.840
military assets in space face increasing vulnerabilities yet currently lack

145
00:09:39.960 --> 00:09:44.279
robust defensive capabilities. The upgraded Centaur would be equipped with

146
00:09:44.320 --> 00:09:48.240
powerful thrusters and substantial energy reserves, allowing it to intercept

147
00:09:48.279 --> 00:09:51.720
potential threats within hours rather than the days or week's

148
00:09:51.759 --> 00:09:56.799
current satellite systems require. Bruno envisions these interceptors as destroyers

149
00:09:57.159 --> 00:10:01.159
or greyhounds of space, providing rapid protecti response for critical

150
00:10:01.159 --> 00:10:06.080
space infrastructure. A key consideration in this defensive system is

151
00:10:06.080 --> 00:10:09.720
the need to neutralize threats without creating dangerous debris fields.

152
00:10:10.440 --> 00:10:13.440
Space debris can persist for weeks in low orbit and

153
00:10:13.480 --> 00:10:17.200
centuries in higher orbits, posing risks to all spacecraft regardless

154
00:10:17.240 --> 00:10:21.200
of nationality. As Bruno notes, space is a shared environment

155
00:10:21.279 --> 00:10:25.919
without borders, making debris management crucial. The timing of this

156
00:10:26.000 --> 00:10:29.399
proposal aligns with the US Space Force's evolving role as

157
00:10:29.440 --> 00:10:33.720
a cornerstone of national defense. With space increasingly becoming what

158
00:10:33.799 --> 00:10:38.240
military officials describe as a contested domain rather than a sanctuary,

159
00:10:38.679 --> 00:10:42.879
The need for defensive capabilities has grown more urgent. Ula

160
00:10:43.000 --> 00:10:45.759
is already preparing for its first Space Force mission, with

161
00:10:45.799 --> 00:10:49.519
the Vulcan Centaur scheduled for late twenty twenty four or

162
00:10:49.559 --> 00:10:54.039
early twenty twenty five. If successful, this defensive upgrade could

163
00:10:54.039 --> 00:10:57.159
provide Ula with a unique capability in the competitive launch

164
00:10:57.159 --> 00:11:02.679
industry while addressing crucial space security needs. And that brings

165
00:11:02.679 --> 00:11:05.559
another episode to a close. Thanks for joining us on
