00:00:00.200 --> 00:00:03.520
Welcome to Astronomy Daily, your source for the latest space

2
00:00:03.560 --> 00:00:07.200
and astronomy news. I'm your host, Anna, and today we've

3
00:00:07.200 --> 00:00:10.320
got an exciting lineup of stories from Mars to black holes,

4
00:00:10.679 --> 00:00:14.480
and some fascinating developments in human spaceflight. So let's get

5
00:00:14.480 --> 00:00:18.760
straight into it. In an exciting discovery that sheds new

6
00:00:18.800 --> 00:00:22.679
light on Mars's ancient past, scientists have found compelling evidence

7
00:00:22.719 --> 00:00:25.239
of hot water existing on the red planet over four

8
00:00:25.239 --> 00:00:28.839
point four or five billion years ago. This groundbreaking finding

9
00:00:28.920 --> 00:00:32.479
comes from analyzing a unique Martian meteorite known as Black Beauty,

10
00:00:32.880 --> 00:00:36.359
which was discovered in the western Sahara Desert in twenty eleven.

11
00:00:36.920 --> 00:00:41.679
The meteorite, officially called NWA seveny thirty four, contains the

12
00:00:41.679 --> 00:00:44.880
most water of any Martian meteorite ever found on Earth.

13
00:00:45.520 --> 00:00:48.759
By studying a tiny grain of zircon within the meteorite,

14
00:00:48.920 --> 00:00:53.799
researchers at Curtain University discovered clear chemical signatures indicating the

15
00:00:53.840 --> 00:00:57.039
presence of water rich fluids during a time of significant

16
00:00:57.119 --> 00:01:02.200
volcanic activity on early Mars. What makes this discovery particularly

17
00:01:02.240 --> 00:01:06.760
significant is that these ancient hydrothermal systems could have provided

18
00:01:06.840 --> 00:01:11.040
ideal conditions for life to potentially emerge. The temperatures of

19
00:01:11.079 --> 00:01:14.079
these systems might have ranged from one hundred to six

20
00:01:14.200 --> 00:01:18.400
hundred degrees celsius, similar to the deep ocean hydrothermal vents

21
00:01:18.719 --> 00:01:22.200
we find on Earth today. The Black Beauty meteorite is

22
00:01:22.280 --> 00:01:26.799
particularly special because it's essentially a sample of Mars's surface soil,

23
00:01:27.239 --> 00:01:30.519
containing hundreds of rock and mineral fragments from various regions

24
00:01:30.519 --> 00:01:33.400
of the planet. It's like having a geological buffet of

25
00:01:33.439 --> 00:01:36.599
Mars right here on Earth. Scientists believe this rock was

26
00:01:36.640 --> 00:01:40.599
ejected from Mars's surface about one point five billion years ago,

27
00:01:40.920 --> 00:01:43.760
before eventually making its way to Earth between five and

28
00:01:43.840 --> 00:01:47.000
ten million years ago. While we've known for some time

29
00:01:47.079 --> 00:01:50.120
that Mars once had liquid water, much of the evidence

30
00:01:50.120 --> 00:01:52.480
suggested the planet was too cold to maintain it for

31
00:01:52.560 --> 00:01:57.280
long periods. However, this new research indicates that hydrothermal systems

32
00:01:57.640 --> 00:02:01.879
driven by volcanic activity and possible meteorite impacts could have

33
00:02:01.959 --> 00:02:07.000
created warm, wet environments that persisted for tens of millions

34
00:02:07.000 --> 00:02:12.039
of years or longer during Mars's earliest history. It's been

35
00:02:12.080 --> 00:02:14.960
a landmark week for Blue Origin, with the company achieving

36
00:02:15.000 --> 00:02:18.159
two major milestones that mark significant steps forward in both

37
00:02:18.199 --> 00:02:22.639
their orbital and suborbital space programs. In a historic first,

38
00:02:23.000 --> 00:02:26.479
Blue Origin has successfully placed their fully integrated New Glen

39
00:02:26.560 --> 00:02:29.479
rocket on the launch pad at Cape Canaveral Space Force Station.

40
00:02:30.400 --> 00:02:34.319
This massive vehicle, standing ninety eight meters tall, now sits

41
00:02:34.360 --> 00:02:37.599
on a steel launch table weighing one point seven million pounds.

42
00:02:38.120 --> 00:02:41.159
While the company hasn't announced a specific launch date, they're

43
00:02:41.199 --> 00:02:43.840
preparing for a crucial static fire test that will be

44
00:02:43.879 --> 00:02:46.439
the first time they fuel up a complete, flight ready

45
00:02:46.479 --> 00:02:50.080
New Glen rocket. The initial mission will carry Blue Origins

46
00:02:50.120 --> 00:02:54.599
innovative Blue Ring technology, designed to provide comprehensive space services,

47
00:02:54.639 --> 00:03:01.520
including hosting, transportation, refueling, and data relay capabilities. This represents

48
00:03:01.560 --> 00:03:04.520
a significant step toward the company's vision of making space

49
00:03:04.560 --> 00:03:09.080
more accessible for various operations. In parallel with this achievement,

50
00:03:09.400 --> 00:03:14.479
Blue Origin celebrated another milestone with their suborbital program, successfully

51
00:03:14.479 --> 00:03:18.840
completing their twenty eighth New Shepherd flight. This mission, designated

52
00:03:19.000 --> 00:03:23.240
NS twenty eight, made history by carrying Emily Callandrelli, known

53
00:03:23.280 --> 00:03:26.240
as the Space Gal, who became the one hundredth woman

54
00:03:26.319 --> 00:03:30.599
to cross the boundary of space. Calandrelly, an aerospace engineer

55
00:03:30.639 --> 00:03:34.960
and science communicator, experienced approximately three minutes of weightlessness during

56
00:03:35.000 --> 00:03:38.479
the ten minute flight. Upon returning, she described the profound

57
00:03:38.520 --> 00:03:42.439
experience of seeing Earth from space, comparing the emotional impact

58
00:03:42.520 --> 00:03:44.520
to that of seeing her children for the first time.

59
00:03:45.319 --> 00:03:48.919
The flight also carried five other passengers, including Sharon and

60
00:03:49.000 --> 00:03:52.080
Mark Hagel, who made their second journey to space aboard

61
00:03:52.120 --> 00:03:56.400
New Shepherd. The mission showcased Blue Origin's continuing commitment to

62
00:03:56.439 --> 00:04:00.280
both advancing space technology and making space more accessible to

63
00:04:00.319 --> 00:04:04.879
a broader range of people. Let's change Pace Now. In

64
00:04:04.919 --> 00:04:09.400
a fascinating new study, researchers have uncovered important insights into

65
00:04:09.400 --> 00:04:14.840
how spending time in space affects astronauts cognitive abilities. The research,

66
00:04:14.879 --> 00:04:18.759
which represents the largest data set of cognitive performance measurements

67
00:04:19.160 --> 00:04:23.519
from professional astronauts ever published, focused on twenty five astronauts

68
00:04:23.600 --> 00:04:28.040
during their approximately six month stays aboard the International Space Station.

69
00:04:28.920 --> 00:04:32.639
While in space, astronauts face unique challenges that our bodies

70
00:04:32.680 --> 00:04:37.199
never encounter on Earth from microgravity and increased radiation, exposure

71
00:04:37.519 --> 00:04:42.279
to demanding work schedules, and disrupted sleep patterns. Despite these

72
00:04:42.399 --> 00:04:47.879
extraordinary conditions, the study found that astronauts maintained impressive cognitive resilience.

73
00:04:48.879 --> 00:04:51.959
The researchers discovered that while astronauts took longer to complete

74
00:04:51.959 --> 00:04:56.639
certain tasks involving processing speed, working memory, and attention, their

75
00:04:56.680 --> 00:05:01.720
accuracy remained unchanged. Interestingly, the these effects weren't uniform across

76
00:05:01.759 --> 00:05:06.120
all cognitive functions. Changes and attention were only observed early

77
00:05:06.160 --> 00:05:10.560
in the missions, while slower processing speeds persisted until after

78
00:05:10.600 --> 00:05:15.000
the astronaut's returned to Earth. Perhaps most reassuringly, the study

79
00:05:15.079 --> 00:05:19.439
found no evidence of lasting cognitive impairment or neurodegenerative decline

80
00:05:19.480 --> 00:05:23.279
after six months in space. The temporary changes observed were

81
00:05:23.279 --> 00:05:26.439
similar to what we might experience on Earth during periods

82
00:05:26.439 --> 00:05:31.360
of stress or sleep deprivation. This research has important implications

83
00:05:31.360 --> 00:05:35.240
for future space exploration, particularly as we look toward longer

84
00:05:35.279 --> 00:05:38.639
missions to the Moon and Mars. Understanding how the human

85
00:05:38.680 --> 00:05:41.759
brain adapts to the space environment will be crucial for

86
00:05:41.800 --> 00:05:45.560
supporting astronaut performance and well being during these extended journeys

87
00:05:45.560 --> 00:05:49.720
into the final frontier. The findings also provide a valuable

88
00:05:49.720 --> 00:05:53.439
baseline for comparing future studies, especially as we begin to

89
00:05:53.519 --> 00:05:57.839
venture deeper into space, where increased radiation exposure and extended

90
00:05:57.839 --> 00:06:01.720
communication delays could pose a daytional challenges to cognitive function.

91
00:06:03.199 --> 00:06:08.199
Some astronomy news now. In an extraordinary astronomical observation, scientists

92
00:06:08.240 --> 00:06:11.759
have witnessed one of the most dramatic galaxy collisions ever recorded,

93
00:06:12.160 --> 00:06:15.920
occurring at a cosmic crossroads known as Stefan's quintet. Using

94
00:06:16.000 --> 00:06:20.120
the powerful William Herschel telescope in La Palma, Spain, researchers

95
00:06:20.160 --> 00:06:24.920
observed galaxy NGCY three hundred and eighteen B tearing through

96
00:06:24.920 --> 00:06:27.720
this galactic grouping at the astounding speed of over two

97
00:06:27.800 --> 00:06:31.120
million miles per hour. That's roughly eight hundred times faster

98
00:06:31.199 --> 00:06:34.600
than an SR seventy one Blackbird jet fighter. This violent

99
00:06:34.680 --> 00:06:38.720
cosmic encounter has created a massive shockwave that has essentially

100
00:06:38.759 --> 00:06:43.720
reawakened this previously peaceful cluster of galaxies. The collision site

101
00:06:43.759 --> 00:06:47.480
represents a complex field of debris from previous galactic mergers,

102
00:06:48.000 --> 00:06:51.480
making it a fascinating laboratory for studying how galaxies like

103
00:06:51.519 --> 00:06:54.920
our own Milky Way are built up through cosmic collisions

104
00:06:54.959 --> 00:06:59.600
over billions of years. What makes this observation particularly intriguing

105
00:07:00.120 --> 00:07:02.639
is the dual nature of the shockwave created by the

106
00:07:02.639 --> 00:07:05.639
collision as it moves through pockets of cold gas at

107
00:07:05.680 --> 00:07:09.560
hypersonic speeds. It's powerful enough to strip electrons from atoms,

108
00:07:09.879 --> 00:07:13.720
leaving behind a glowing trail of charged plasma. However, when

109
00:07:13.720 --> 00:07:17.120
the same shockwave encounters hot gas surrounding the collision site,

110
00:07:17.240 --> 00:07:20.480
it weakens and instead compresses the gas, producing radio waves

111
00:07:20.480 --> 00:07:23.959
that astronomers can detect. To capture the full scope of

112
00:07:23.959 --> 00:07:28.600
this cosmic drama, the research team combined observations from multiple instruments,

113
00:07:29.040 --> 00:07:32.480
including the James Web Space Telescope and the Low Frequency Array.

114
00:07:33.079 --> 00:07:36.920
This comprehensive approach has provided unprecedented detail of the collision

115
00:07:37.000 --> 00:07:41.480
and its aftermath, offering valuable insights into galaxy evolution and

116
00:07:41.519 --> 00:07:46.000
the fundamental processes that shape our universe. This discovery represents

117
00:07:46.000 --> 00:07:49.600
more than just a spectacular cosmic light show. It's providing

118
00:07:49.639 --> 00:07:53.959
astronomers with a unique opportunity to study galaxy evolution in action,

119
00:07:54.560 --> 00:07:58.720
showing us how these massive celestial structures interact and transform

120
00:07:59.120 --> 00:08:02.399
through violent and care counters that unfold over millions of years.

121
00:08:03.399 --> 00:08:07.079
And in a fascinating discovery that's puzzling astronomers, a pair

122
00:08:07.160 --> 00:08:11.279
of massive black holes has been spotted creating unusual bursts

123
00:08:11.319 --> 00:08:14.040
of light about a billion light years away in the

124
00:08:14.040 --> 00:08:19.240
constellation's sickness. What makes this discovery. Particularly intriguing is that

125
00:08:19.279 --> 00:08:22.759
these light bursts appear to follow a regular pattern, something

126
00:08:22.839 --> 00:08:25.560
we've never seen before in this type of system. These

127
00:08:25.560 --> 00:08:28.959
cosmic giants are locked in an incredibly close orbital dance,

128
00:08:29.319 --> 00:08:33.039
separated by just sixteen billion miles, a distance that light

129
00:08:33.080 --> 00:08:36.120
can cross in only a day. They're completing their orbit

130
00:08:36.159 --> 00:08:38.600
around each other every one hundred and thirty days, and

131
00:08:38.639 --> 00:08:42.000
in the process, they're putting on quite a show. Over

132
00:08:42.039 --> 00:08:44.600
the past three years, these black holes have been feasting

133
00:08:44.639 --> 00:08:47.879
on what appears to be a massive gas cloud, consuming

134
00:08:47.879 --> 00:08:50.559
the equivalent of about two times the mass of our Sun.

135
00:08:51.320 --> 00:08:54.320
The story of this discovery begins back in March twenty

136
00:08:54.320 --> 00:08:57.960
twenty one, when an automated alert system at the Zwiki

137
00:08:58.039 --> 00:09:03.519
Transient Facility in California first spotted these unusual emissions. Initially,

138
00:09:03.600 --> 00:09:06.519
astronomers thought they were looking at a supernova, but the

139
00:09:06.639 --> 00:09:10.440
repeated outbursts in twenty twenty two suggested something else was

140
00:09:10.480 --> 00:09:14.000
at play. What they observed was an M shaped pattern

141
00:09:14.080 --> 00:09:16.360
in the data that kept showing up every two to

142
00:09:16.440 --> 00:09:19.600
three months, something that couldn't be explained by either a

143
00:09:19.639 --> 00:09:24.080
supernova or typical black hole behavior. The current theory is

144
00:09:24.080 --> 00:09:27.080
that these black holes are tearing apart a massive gas

145
00:09:27.080 --> 00:09:30.000
cloud that crossed their path. Each time one of the

146
00:09:30.039 --> 00:09:33.759
black holes passes through this cloud, it creates these distinctive

147
00:09:33.840 --> 00:09:37.440
light bursts. What's even more remarkable is that these cosmic

148
00:09:37.480 --> 00:09:41.200
giants are on a collision course. Astronomers predict they'll merge

149
00:09:41.200 --> 00:09:44.240
in about seventy thousand years, an event that will send

150
00:09:44.360 --> 00:09:48.480
ripples through the fabric of space time itself. This discovery

151
00:09:48.559 --> 00:09:51.480
opens up new questions about how black holes interact with

152
00:09:51.519 --> 00:09:55.639
their environment and with each other. It's yet another reminder

153
00:09:55.679 --> 00:10:00.080
that even after centuries of astronomical observations, the universe still

154
00:10:00.120 --> 00:10:04.279
has plenty of surprises in store for us. Finally, today,

155
00:10:05.240 --> 00:10:08.399
China has achieved a significant milestone in their space program

156
00:10:08.679 --> 00:10:12.080
with the successful test of their first inflatable space module

157
00:10:12.879 --> 00:10:17.120
during the recent Shijian nineteen mission. Chinese engineers quietly conducted

158
00:10:17.120 --> 00:10:22.440
this groundbreaking experiment, demonstrating their growing capabilities in advanced space technology.

159
00:10:23.159 --> 00:10:26.919
The innovative module, developed by the China Academy of Space Technology,

160
00:10:27.399 --> 00:10:30.120
features a unique design that allows it to be launched

161
00:10:30.159 --> 00:10:34.080
in a compressed folded state and then inflated once in orbit.

162
00:10:34.840 --> 00:10:38.360
This approach offers several advantages, particularly in terms of weight

163
00:10:38.399 --> 00:10:43.200
savings and launch efficiency, crucial factors in space exploration. What

164
00:10:43.320 --> 00:10:47.600
makes this technology particularly promising is its potential applications for

165
00:10:47.679 --> 00:10:52.279
future space stations and deep space missions. The module is

166
00:10:52.279 --> 00:10:57.080
constructed from flexible composite materials and underwent rigorous testing before launch,

167
00:10:57.480 --> 00:11:02.080
including trials for air tightness, debris impact resistance, and performance

168
00:11:02.159 --> 00:11:07.039
under extreme pressure and temperature conditions. This development puts China

169
00:11:07.120 --> 00:11:10.759
in the company of other spacefaring nations and private companies

170
00:11:10.799 --> 00:11:15.120
working on similar technology. While organizations like NASA have already

171
00:11:15.200 --> 00:11:19.799
tested expandable modules on the International Space Station, China's success

172
00:11:19.840 --> 00:11:23.600
with their own version represents a significant step forward in

173
00:11:23.639 --> 00:11:26.799
their space capabilities. The test was part of the broader

174
00:11:26.879 --> 00:11:30.919
Shijian nineteen mission, which returned safely to Earth in October

175
00:11:30.960 --> 00:11:35.120
after completing its objectives. While the exact size and specifications

176
00:11:35.120 --> 00:11:39.360
of the module haven't been disclosed, this achievement suggests China

177
00:11:39.480 --> 00:11:43.919
is actively working toward expanding their space presence, potentially incorporating

178
00:11:43.960 --> 00:11:47.360
this technology into future additions to their Tiangong space station,

179
00:11:49.399 --> 00:11:51.559
and that brings us to the end of today's episode
