00:00:00,280 --> 00:00:03,439
Speaker 1: Welcome to Astronomy Daily, your window to the universe, where

2
00:00:03,439 --> 00:00:06,280
we bring you the freshest discoveries and developments from across

3
00:00:06,280 --> 00:00:09,640
the cosmos. I'm Anna and I'm thrilled to guide you

4
00:00:09,759 --> 00:00:14,279
through today's fascinating journey through space. In today's episode, we'll

5
00:00:14,320 --> 00:00:18,079
explore a remarkable observation of a black hole violently expelling

6
00:00:18,079 --> 00:00:22,000
matter at incredible speeds into deep space. We'll also cover

7
00:00:22,079 --> 00:00:25,559
SpaceX's impressive launch milestones and the global surge and space

8
00:00:25,600 --> 00:00:29,559
activities happening around the world. Plus we'll discuss the historic

9
00:00:29,600 --> 00:00:32,920
inauguration of the African Space Agency and what it means

10
00:00:32,920 --> 00:00:36,479
for the continent's space ambitions. And finally, we'll venture to

11
00:00:36,560 --> 00:00:40,399
our Moon, where a massive ancient crater may hold secrets

12
00:00:40,399 --> 00:00:44,320
about our lunar companion's fiery birth. So settle in as

13
00:00:44,359 --> 00:00:47,320
we blast off into another edition of astronomical wonders and

14
00:00:47,359 --> 00:00:52,920
cosmic revelations. In a stunning discovery that challenges our understanding

15
00:00:52,920 --> 00:00:56,880
of these cosmic monsters, scientists have captured a black hole

16
00:00:57,000 --> 00:00:59,799
in the act of hurling matter into deep space at

17
00:00:59,920 --> 00:01:04,120
us astonishing velocities. The culprit is located in NGC four

18
00:01:04,200 --> 00:01:07,959
thousand nine hundred forty five, a beautiful spiral galaxy sitting

19
00:01:08,040 --> 00:01:11,000
over twelve million light years away in the constellation Centaurus.

20
00:01:12,120 --> 00:01:15,760
While NGC four nine hundred forty five might appear serene

21
00:01:15,760 --> 00:01:19,400
from a distance, it harbours a ferocious secret at its core.

22
00:01:19,920 --> 00:01:23,560
Unlike some black holes that quietly consume their cosmic meals,

23
00:01:23,599 --> 00:01:25,879
such as the relatively calm one at the center of

24
00:01:25,920 --> 00:01:29,000
our own Milky Way, this supermassive beast is both a

25
00:01:29,079 --> 00:01:33,599
voracious eater and a violent expeller. Using the Advanced Meuse

26
00:01:33,599 --> 00:01:38,120
instrument on the European Southern Observatory's very large telescope, astronomers

27
00:01:38,120 --> 00:01:41,640
have documented this black hole not only devouring surrounding material,

28
00:01:42,000 --> 00:01:45,519
but also generating powerful cone shaped winds of gas and

29
00:01:45,640 --> 00:01:50,040
dust that blast outward with tremendous force. What's particularly fascinating

30
00:01:50,120 --> 00:01:53,840
is that these outflows, visible as striking red plumes against

31
00:01:53,840 --> 00:01:58,120
the galaxy's elegant spiral structure, are moving so rapidly that

32
00:01:58,200 --> 00:02:02,359
scientists expect them to completely escape the galaxy's gravitational pull.

33
00:02:03,040 --> 00:02:05,840
This matter will eventually drift into the vast emptiness of

34
00:02:05,920 --> 00:02:11,280
intergalactic space, a cosmic ejection on a truly enormous scale.

35
00:02:11,319 --> 00:02:16,080
This observation is reshaping our understanding of galactic dynamics. Black

36
00:02:16,080 --> 00:02:18,599
holes have long been known to pull matter inward with

37
00:02:18,680 --> 00:02:22,520
their immense gravity, but this dramatic example of matter ejection

38
00:02:23,319 --> 00:02:26,599
shows how these cosmic entities play a much more complex

39
00:02:26,680 --> 00:02:31,039
role in shaping their galactic neighborhoods. The expelled material, which

40
00:02:31,080 --> 00:02:34,639
would otherwise be available for star formation, is essentially being

41
00:02:34,680 --> 00:02:39,319
removed from the galaxy's inventory. This finding represents a pivotal

42
00:02:39,360 --> 00:02:43,039
moment in our quest to understand the intricate relationship between

43
00:02:43,120 --> 00:02:46,960
supermassive black holes and the evolution of their host galaxies

44
00:02:47,319 --> 00:02:52,319
across cosmic time. What makes this discovery truly revolutionary is

45
00:02:52,319 --> 00:02:55,479
that these black hole driven winds behave in ways astronomers

46
00:02:55,520 --> 00:03:00,879
didn't anticipate. The meuse data reveals something counterintuitive. Instead of

47
00:03:00,919 --> 00:03:03,919
gradually slowing down as they travel outward through the galaxy,

48
00:03:04,400 --> 00:03:07,639
these powerful outflows actually accelerate as they move away from

49
00:03:07,639 --> 00:03:10,800
the galactic center. They gain momentum on their journey toward

50
00:03:10,840 --> 00:03:14,360
the edge of the galaxy and eventually into inner galactic space.

51
00:03:15,439 --> 00:03:19,919
This acceleration mechanism is particularly significant for understanding galactic evolution.

52
00:03:20,840 --> 00:03:24,599
By forcefully ejecting potential star forming material from the galaxy.

53
00:03:25,039 --> 00:03:29,120
These black holes effectively act as cosmic regulators, controlling the

54
00:03:29,199 --> 00:03:33,000
rate at which new stars can form within their host galaxies.

55
00:03:33,599 --> 00:03:36,520
It's a form of self regulation that dampens stellar birth

56
00:03:36,639 --> 00:03:41,240
rates across the entire galactic structure. Even more fascinating is

57
00:03:41,280 --> 00:03:44,080
how this process creates a feedback loop that affects the

58
00:03:44,120 --> 00:03:47,719
black hole itself by removing the very gas and dust

59
00:03:47,800 --> 00:03:51,879
they feed upon, more active and powerful black holes actually

60
00:03:51,919 --> 00:03:56,599
impede their own growth. This self limiting behavior drives the

61
00:03:56,680 --> 00:04:00,960
whole system toward a kind of galactic equilibrium, delicate balance

62
00:04:01,000 --> 00:04:05,520
between consumption and ejection. The new findings represent a significant

63
00:04:05,520 --> 00:04:08,280
step forward in our understanding of how galaxies evolve over

64
00:04:08,319 --> 00:04:11,759
cosmic time. These accelerating winds appear to be a key

65
00:04:11,800 --> 00:04:16,000
mechanism through which black holes shape not just their immediate surroundings,

66
00:04:16,000 --> 00:04:20,079
but the fate of entire galaxies. By regulating both star

67
00:04:20,199 --> 00:04:24,240
formation and their own feeding processes, these cosmic behemoths play

68
00:04:24,279 --> 00:04:29,160
a far more sophisticated role in universal dynamics than previously understood.

69
00:04:30,000 --> 00:04:33,639
Scientists believe that by studying these acceleration patterns in detail,

70
00:04:34,079 --> 00:04:37,040
we can better comprehend the forces that have shaped galactic

71
00:04:37,079 --> 00:04:41,680
evolution throughout the universe's history, one of the fundamental questions

72
00:04:41,720 --> 00:04:46,079
in modern astrophysics. Let's move on now and take a

73
00:04:46,120 --> 00:04:49,240
look at this week's launch schedule. SpaceX continues to push

74
00:04:49,279 --> 00:04:52,079
the boundaries of what's possible in the commercial space industry,

75
00:04:52,439 --> 00:04:55,319
setting remarkable records that would have seemed impossible just a

76
00:04:55,360 --> 00:04:58,000
few years ago. The company is on track to achieve

77
00:04:58,000 --> 00:05:00,160
its two hundred and fiftieth mission launch from space Base

78
00:05:00,240 --> 00:05:03,959
Launch Complex forty in Florida this week, a milestone that

79
00:05:04,040 --> 00:05:07,560
highlights just how quickly SpaceX has transformed access to space.

80
00:05:08,120 --> 00:05:11,680
The pace of launches is nothing short of extraordinary. SpaceX

81
00:05:11,680 --> 00:05:15,079
has now surpassed two hundred and fifty dedicated Starlink launches,

82
00:05:15,519 --> 00:05:19,959
rapidly expanding its satellite Internet constellation to provide global coverage.

83
00:05:20,079 --> 00:05:22,680
Just last week, the company deployed a record twenty nine

84
00:05:22,720 --> 00:05:26,560
Starlink satellites in a single mission, demonstrating their ability to

85
00:05:26,680 --> 00:05:32,040
maximize payload capacity on their workhourse Falcon nine rocket. This

86
00:05:32,120 --> 00:05:36,000
achievement is particularly noteworthy because it also marked SpaceX's fiftieth

87
00:05:36,079 --> 00:05:39,439
mission of twenty twenty five, maintaining a launch cadence that

88
00:05:39,480 --> 00:05:43,360
averages nearly three launches per week. If this pace continues,

89
00:05:43,519 --> 00:05:46,240
the company is on track to potentially exceed one hundred

90
00:05:46,279 --> 00:05:49,759
launches this year, a figure that the entire global launch

91
00:05:49,759 --> 00:05:54,600
industry struggled to achieve collectively just a decade ago. Perhaps

92
00:05:54,720 --> 00:06:00,759
equally impressive is SpaceX's growing mastery of reusability. Mission marked

93
00:06:00,759 --> 00:06:04,079
the one hundredth consecutive successful Falcon nine landing since their

94
00:06:04,160 --> 00:06:08,439
last landing failure. This perfect landing streak highlights the maturity

95
00:06:08,439 --> 00:06:13,000
of SpaceX's recovery technology and operations. The booster used for

96
00:06:13,040 --> 00:06:17,439
this mission, designated B one thousand, seventy eight, became the

97
00:06:17,519 --> 00:06:21,000
ninth in the fleet to reach twenty flights, demonstrating the

98
00:06:21,079 --> 00:06:25,240
durability and reliability of these vehicles that were initially designed

99
00:06:25,240 --> 00:06:28,600
for just a handful of missions. The economics of this

100
00:06:28,639 --> 00:06:33,480
reusability revolution cannot be overstated. By recovering and refurbishing first

101
00:06:33,480 --> 00:06:38,680
stage boosters, SpaceX has dramatically reduced launch costs while simultaneously

102
00:06:38,680 --> 00:06:42,680
increasing their launch capacity. What once required building dozens of

103
00:06:42,720 --> 00:06:45,680
new rockets annually can now be accomplished with a much

104
00:06:45,720 --> 00:06:50,160
smaller fleet of frequently flown vehicles. This unprecedented launch cadence

105
00:06:50,199 --> 00:06:53,759
is enabling SpaceX to deploy its Starlink constellation at a

106
00:06:53,800 --> 00:06:57,240
pace that competitors struggle to match. With each launch carrying

107
00:06:57,319 --> 00:07:00,279
dozens of satellites, the company is rapidly approaching the point

108
00:07:00,279 --> 00:07:03,399
where it can offer true global coverage for its Internet service,

109
00:07:03,879 --> 00:07:07,959
including in remote and underserved regions where traditional internet infrastructure

110
00:07:08,000 --> 00:07:13,360
is impractical. While SpaceX dominates headlines with its impressive launch schedule,

111
00:07:13,879 --> 00:07:16,360
it's worth noting that they're not the only players in

112
00:07:16,399 --> 00:07:21,879
this increasingly busy orbital traffic pattern. Other spacefaring nations continue

113
00:07:21,879 --> 00:07:26,120
to maintain active launch schedules, with China being particularly noteworthy

114
00:07:26,120 --> 00:07:29,519
among them. In fact, China attempted to launch one of

115
00:07:29,560 --> 00:07:33,399
its Changjeng twelve A rockets earlier this week, though the

116
00:07:33,439 --> 00:07:36,720
mission was scrubbed for reasons that haven't been officially disclosed.

117
00:07:37,439 --> 00:07:40,279
This particular rocket was set to carry the fourth batch

118
00:07:40,360 --> 00:07:44,879
of Shingwang satellites for the Guawang Network, one of two

119
00:07:44,959 --> 00:07:48,800
mega constellations China is developing to compete with Starlink in

120
00:07:48,839 --> 00:07:52,959
the global satellite internet market. April twenty twenty five has

121
00:07:53,040 --> 00:07:55,439
now secured its place in the record books as the

122
00:07:55,439 --> 00:07:59,560
busiest April in spaceflight history, with an impressive twenty six

123
00:07:59,639 --> 00:08:05,439
rockets launching worldwide. This remarkable achievement reflects the growing commercialization

124
00:08:05,600 --> 00:08:10,160
and accessibility of space launch capabilities across multiple countries and

125
00:08:10,199 --> 00:08:14,439
private companies. Even more impressive was the flurry of activity

126
00:08:14,480 --> 00:08:17,240
that occurred at the end of the month. Between April

127
00:08:17,279 --> 00:08:20,319
twenty eighth and twenty ninth, a new global launch record

128
00:08:20,399 --> 00:08:24,079
was set when six different rockets blasted off within just

129
00:08:24,199 --> 00:08:28,560
eighteen hours of each other. This unprecedented concentration of launches

130
00:08:28,600 --> 00:08:33,120
required careful coordination among various launch providers and space traffic

131
00:08:33,159 --> 00:08:37,919
management authorities to ensure safe operations. This accelerating pace of

132
00:08:38,000 --> 00:08:41,720
launches is expected to continue throughout May and beyond, with

133
00:08:41,799 --> 00:08:46,600
additional starlink missions, crude launches to space stations, and various

134
00:08:46,639 --> 00:08:51,120
satellite deployments already on the manifest. We're witnessing a historic

135
00:08:51,120 --> 00:08:54,519
transformation in how frequently humanity accesses space, and the trend

136
00:08:54,559 --> 00:08:58,159
shows no signs of slowing down. The space industry's rapid

137
00:08:58,200 --> 00:09:02,000
growth presents both opportunities and challenge leunges. While increased launch

138
00:09:02,000 --> 00:09:07,360
cadence means more satellites for communications, Earth observation, and scientific research,

139
00:09:07,799 --> 00:09:12,000
it also creates concerns about orbital congestion and space debris management.

140
00:09:12,720 --> 00:09:17,120
International cooperation on space traffic management is becoming increasingly crucial

141
00:09:17,639 --> 00:09:22,120
as more rockets and satellites fill the skies and another

142
00:09:22,159 --> 00:09:24,879
new player has just run onto the playing field. On

143
00:09:24,960 --> 00:09:29,000
April twentieth, twenty twenty five, a significant milestone in African

144
00:09:29,039 --> 00:09:32,519
space exploration was achieved with the formal inauguration of the

145
00:09:32,559 --> 00:09:38,120
African Space Agency or AFSA, in Cairo, Egypt. This development

146
00:09:38,159 --> 00:09:41,360
marks nearly a decade of coordinated planning since twenty sixteen,

147
00:09:41,720 --> 00:09:45,000
when the African Union first adopted the comprehensive African Space

148
00:09:45,039 --> 00:09:49,720
Policy and Strategy Framework. The creation of AFSA represents a

149
00:09:49,759 --> 00:09:53,679
deliberate move to unite the continent's space ambitions under a

150
00:09:53,720 --> 00:09:59,080
single organizational umbrella. Currently, twenty two African nations operate their

151
00:09:59,080 --> 00:10:03,240
own space agency, with varying degrees of legislative support and

152
00:10:03,399 --> 00:10:08,840
organizational structures. Some are fully independent agencies backed by national legislation,

153
00:10:09,320 --> 00:10:14,000
while others function as departments within broader research institutions. This

154
00:10:14,120 --> 00:10:17,519
new continental agency will serve as the coordinating body for

155
00:10:17,559 --> 00:10:23,120
Africa's existing space programs, streamlining cooperation between member states and

156
00:10:23,279 --> 00:10:28,399
creating a unified voice when engaging with international partners. Rather

157
00:10:28,440 --> 00:10:33,159
than replacing national agencies, AFSA will amplify their collective impact

158
00:10:33,279 --> 00:10:38,279
through strategic coordination. The agency's mandate includes establishing a centralized

159
00:10:38,279 --> 00:10:43,200
point of contact for negotiations with private launch providers, satellite manufacturers,

160
00:10:43,200 --> 00:10:47,399
and other space services companies. This unified approach gives African

161
00:10:47,480 --> 00:10:50,799
nations significantly more leverage in these discussions than they would

162
00:10:50,879 --> 00:10:55,720
have individually. Doctor tidian Ouatara, president of the AFSA Council,

163
00:10:56,200 --> 00:10:59,639
emphasized at the launch ceremony that the agency will focus

164
00:10:59,639 --> 00:11:05,639
on pactical applications that benefit African citizens, including improved agricultural forecasting,

165
00:11:05,960 --> 00:11:12,799
disaster monitoring, telecommunications infrastructure, and educational opportunities. Many African space

166
00:11:12,799 --> 00:11:17,360
agencies already specialize in earth observation missions, tracking climate patterns

167
00:11:17,360 --> 00:11:21,919
crucial for agriculture, and providing services like navigation systems and

168
00:11:22,000 --> 00:11:26,679
emergency response coordination. The South African National Space Agency, for example,

169
00:11:27,000 --> 00:11:30,960
has developed a successful satellite based wildfire detection system that

170
00:11:31,080 --> 00:11:36,559
identifies remote blazes and alerts firefighting authorities. Through AFSA, these

171
00:11:36,600 --> 00:11:41,000
specialized capabilities can now be shared more effectively across borders,

172
00:11:41,480 --> 00:11:45,080
creating a multiplier effect that benefits all member states while

173
00:11:45,120 --> 00:11:49,159
avoiding costly duplication of efforts. The agency will also play

174
00:11:49,200 --> 00:11:53,360
a crucial role in standardizing regulations, protocols, and technological systems

175
00:11:53,399 --> 00:11:58,039
across the continent's space sector. Despite Africa's vast geographical footprint

176
00:11:58,080 --> 00:12:01,600
covering one fifth of Earth's land surface, the continent currently

177
00:12:01,600 --> 00:12:04,919
contributes a mere zero point five percent to the global

178
00:12:04,919 --> 00:12:10,519
space budget. This stark disparity highlights the significant untapped potential

179
00:12:10,720 --> 00:12:15,200
within Africa's space sector. The newly established African Space Agency

180
00:12:15,600 --> 00:12:19,840
aims to fundamentally transform this reality, pivoting the continent from

181
00:12:19,919 --> 00:12:23,799
being primarily a consumer of space technology and data to

182
00:12:23,879 --> 00:12:28,759
becoming an active producer and innovator. As doctor Uatara aptly

183
00:12:28,799 --> 00:12:33,120
described it, Africa is a sleeping giant in the space economy,

184
00:12:34,080 --> 00:12:38,279
with ambitious projections estimating space economy revenue reaching twenty two

185
00:12:38,279 --> 00:12:42,440
billion dollars by twenty twenty six. The agency recognizes that

186
00:12:42,559 --> 00:12:46,120
current activities have only scratched the surface of what's possible.

187
00:12:46,960 --> 00:12:50,799
The focus now is on leveraging Africa's abundant natural resources,

188
00:12:51,120 --> 00:12:54,919
alongside its growing pool of engineering talent, to develop indigenous

189
00:12:54,960 --> 00:13:00,720
space capabilities, rather than relying on imported solutions. Key pillars

190
00:13:00,799 --> 00:13:05,039
form the foundation of AFSA's approach, recognizing the necessity of

191
00:13:05,080 --> 00:13:10,240
space technologies for development, establishing robust structural frameworks to support growth,

192
00:13:10,559 --> 00:13:14,559
and positioning Africa advantageously within the emerging landscapes of new

193
00:13:14,639 --> 00:13:20,279
space and artificial intelligence. Infrastructure development stands as a critical priority,

194
00:13:20,600 --> 00:13:24,399
with plans to both incorporate existing facilities and construct new

195
00:13:24,440 --> 00:13:28,320
ones across member states. This doesn't solely involve physical launch

196
00:13:28,360 --> 00:13:33,399
sites and satellite manufacturing capabilities, but also encompasses developing specialized

197
00:13:33,519 --> 00:13:37,720
educational programs and training opportunities to build a skilled workforce.

198
00:13:38,679 --> 00:13:42,120
The agency will emphasize educational initiatives at all levels, from

199
00:13:42,159 --> 00:13:45,960
primary school programs that spark interest in space sciences to

200
00:13:46,039 --> 00:13:49,960
advanced university curricula that produce the next generation of African

201
00:13:49,960 --> 00:13:56,279
aerospace engineers, astrophysicists, and mission specialists. Creating this human capital

202
00:13:56,320 --> 00:13:59,759
pipeline is considered essential for sustainable growth in the sector.

203
00:14:00,519 --> 00:14:05,440
Resource coordination represents another major focus area. Given the substantial

204
00:14:05,480 --> 00:14:10,240
investment required for space programs, AFSA will facilitate resource sharing

205
00:14:10,279 --> 00:14:14,840
among member states, preventing costly duplication of efforts while maximizing

206
00:14:14,879 --> 00:14:19,399
the impact of available funding. This cooperative approach extends to

207
00:14:19,480 --> 00:14:25,360
sharing markets, technologies, and scientific outcomes. Through these coordinated efforts,

208
00:14:25,759 --> 00:14:28,559
Africa aims to claim its rightful place in the global

209
00:14:28,600 --> 00:14:32,879
space community, transforming from a minor player to a significant

210
00:14:32,919 --> 00:14:39,080
contributor in international space exploration and utilization. Let's change gears now.

211
00:14:39,960 --> 00:14:43,840
Approximately four point three billion years ago, a massive celestial

212
00:14:43,840 --> 00:14:47,159
body slammed into the lunar surface, creating what we now

213
00:14:47,200 --> 00:14:51,679
know as the South Pole Eightken Basin. This colossal impact crater,

214
00:14:52,120 --> 00:14:55,039
spanning a significant portion of the Moon's far side, may

215
00:14:55,080 --> 00:14:58,440
hold secrets that could revolutionize our understanding of lunar formation.

216
00:14:59,440 --> 00:15:03,039
Recent recent search suggests this basin contains pristine fragments of

217
00:15:03,080 --> 00:15:06,080
the Moon's mantle and remnants of an ancient magma ocean,

218
00:15:06,519 --> 00:15:09,039
dating back to when our lunar companion was still cooling

219
00:15:09,080 --> 00:15:13,519
and solidifying after its violent birth. These materials offer a

220
00:15:13,679 --> 00:15:17,840
rare geological time capsule, preserving evidence from the final stages

221
00:15:17,879 --> 00:15:22,120
of the Moon's formation process. What makes this discovery particularly

222
00:15:22,120 --> 00:15:27,360
intriguing is how it challenges previous scientific assumptions. Researchers studying

223
00:15:27,360 --> 00:15:31,120
the basin's distinctive teardrop shape have determined that the massive

224
00:15:31,159 --> 00:15:35,600
impactor was actually moving southward when it struck the lunar surface,

225
00:15:36,080 --> 00:15:40,919
not northward as previously thought, As planetary scientist Jeff Andrews

226
00:15:40,919 --> 00:15:43,840
Hannah from the University of Arizona noted, we have had

227
00:15:43,879 --> 00:15:45,759
the data we needed to measure the shape of the

228
00:15:45,799 --> 00:15:48,080
basin for a long time. It just took a different

229
00:15:48,120 --> 00:15:51,519
perspective to view the basin this way. The impact was

230
00:15:51,519 --> 00:15:53,759
so powerful that it appears to have punctured through the

231
00:15:53,840 --> 00:15:57,879
lunar crust, allowing material from the still crystallizing magma ocean

232
00:15:57,960 --> 00:16:02,080
beneath to seep upward. This explains the presence of thorium

233
00:16:02,120 --> 00:16:07,000
and other distinctive elements consistent with creep materials, potassium, rare

234
00:16:07,039 --> 00:16:11,519
earth elements, and phosphorus found across the basin floor. This

235
00:16:11,679 --> 00:16:15,200
excavation provides a unique window into the Moon's interior during

236
00:16:15,200 --> 00:16:18,679
a critical period of its evolution. When the Moon first

237
00:16:18,720 --> 00:16:21,399
formed from debris following a collision between Earth and a

238
00:16:21,440 --> 00:16:25,919
Mars sized object. Both bodies were briefly liquefied. As the

239
00:16:25,960 --> 00:16:30,200
Moon cooled, low density minerals floated upward to form the crust,

240
00:16:30,600 --> 00:16:34,440
while denser materials sank inward, creating the distinct layers we

241
00:16:34,519 --> 00:16:38,960
observe today. The South Pole eight con basin effectively captured

242
00:16:38,960 --> 00:16:42,200
a snapshot of this process in action, preserving evidence of

243
00:16:42,240 --> 00:16:46,559
the magma Ocean's composition at a specific moment in lunar history.

244
00:16:46,919 --> 00:16:50,759
By analyzing these materials, scientists hope to refine our timeline

245
00:16:50,759 --> 00:16:55,159
of exactly when and how Earth's companion took shape. The

246
00:16:55,240 --> 00:16:58,679
upcoming Artemis missions represent a once in a generation opportunity

247
00:16:58,679 --> 00:17:02,919
to answer fundamental questions about lunar formation. When astronauts return

248
00:17:03,000 --> 00:17:05,880
to the Moon in twenty twenty six, they'll be able

249
00:17:05,920 --> 00:17:08,720
to collect and bring back samples from the South Pole

250
00:17:08,799 --> 00:17:12,839
eight can basin, giving scientists direct access to materials from

251
00:17:12,880 --> 00:17:18,039
the Moon's ancient mantle. These samples are particularly valuable because

252
00:17:18,079 --> 00:17:21,039
they can be compared with materials already in our possession.

253
00:17:21,960 --> 00:17:24,920
During the Apollo missions of the nineteen sixties and seventies,

254
00:17:25,400 --> 00:17:29,960
astronauts returned with rocks from the Proselarum creep terrain, another

255
00:17:30,000 --> 00:17:34,519
region rich in those distinctive potassium, rare earth elements and

256
00:17:34,519 --> 00:17:39,319
phosphorus materials. More recently, China's Chang of five mission in

257
00:17:39,319 --> 00:17:43,160
twenty twenty and Chang six in twenty twenty four have

258
00:17:43,279 --> 00:17:46,279
added to our collection of lunar samples, with the latter

259
00:17:46,359 --> 00:17:49,680
specifically returning materials from the South Pole eight Can basin.

260
00:17:50,720 --> 00:17:54,160
What makes this scientific opportunity so compelling is that these

261
00:17:54,200 --> 00:17:59,559
different areas represent distinct snapshots in time. By analyzing materials

262
00:17:59,559 --> 00:18:03,119
from both regions, scientists can observe how the lunar magma

263
00:18:03,160 --> 00:18:07,079
ocean evolved during different periods. It's like having photographs of

264
00:18:07,119 --> 00:18:10,480
a developing child taken years apart. The differences tell a

265
00:18:10,519 --> 00:18:14,400
story of growth and change. Andrew's Hannah emphasized that this

266
00:18:14,519 --> 00:18:18,559
research is about more than just understanding the Moon. The

267
00:18:18,599 --> 00:18:21,599
magma ocean is inextricably tied to the birth of Earth.

268
00:18:21,680 --> 00:18:25,079
He explained. While scientists have general timelines for how long

269
00:18:25,160 --> 00:18:28,640
it took the lunar magma ocean to crystallize, precise dating

270
00:18:28,640 --> 00:18:33,799
remains challenging. Once Artemis astronauts return with these samples, laboratory

271
00:18:33,799 --> 00:18:36,640
analysis can determine a precise age for the South Pole

272
00:18:36,680 --> 00:18:40,000
eight Can basin, which will provide an exact timeline for

273
00:18:40,039 --> 00:18:43,839
the late stage magma ocean crystallization. This data will help

274
00:18:43,880 --> 00:18:46,799
scientists refine models of how both the Moon and Earth

275
00:18:46,880 --> 00:18:50,960
formed and evolved in their earliest days. The comparison between

276
00:18:51,000 --> 00:18:54,119
the South Pole eight Can basin and the Procellarum creep

277
00:18:54,240 --> 00:18:59,079
terrain holds additional significance because previous theories suggested the massive

278
00:18:59,160 --> 00:19:02,880
impact that created the basin might have pushed magma ocean

279
00:19:02,920 --> 00:19:05,880
material to the opposite side of the Moon, forming the

280
00:19:05,880 --> 00:19:11,799
Prosollarum region. New evidence indicates these areas formed independently with

281
00:19:11,880 --> 00:19:15,359
the South Pole eight can impact occurring earlier in lunar history.

282
00:19:17,319 --> 00:19:20,559
And with that we wrap up our cosmic journey for today.

283
00:19:21,240 --> 00:19:24,160
From black holes hurling matter into deep space to new

284
00:19:24,160 --> 00:19:28,279
revelations about the Moon's ancient magma oceans, We've traveled across

285
00:19:28,279 --> 00:19:32,359
our Solar system and beyond. The universe continues to reveal

286
00:19:32,400 --> 00:19:35,359
its secrets to those patient enough to look and listen.

287
00:19:36,559 --> 00:19:39,359
As we observe Africa taking bold new steps into the

288
00:19:39,400 --> 00:19:43,119
space arena and anticipate what artemis astronauts might discover on

289
00:19:43,160 --> 00:19:47,039
the lunar surface, it's clear that space exploration remains one

290
00:19:47,079 --> 00:19:51,160
of humanity's greatest adventures. I'm Anna, and I want to

291
00:19:51,160 --> 00:19:54,279
thank you for spending this time exploring the cosmos with me.
