00:00:00.320 --> 00:00:03.280
Avery: Hello, and welcome to Astronomy Daily, the

1
00:00:03.280 --> 00:00:05.680
podcast that brings the universe down to

2
00:00:05.680 --> 00:00:07.680
Earth. I'm your host, Avery.

3
00:00:07.760 --> 00:00:10.280
Anna: And I'm Anna. It's great to be with you all

4
00:00:10.280 --> 00:00:12.960
again, Avery. The cosmos has been

5
00:00:12.960 --> 00:00:15.520
busy, and we have some great stories for you.

6
00:00:15.919 --> 00:00:18.640
Avery: You are not kidding. We're talking about a

7
00:00:18.640 --> 00:00:21.400
historic change at the top of NASA. A

8
00:00:21.400 --> 00:00:23.360
supermassive black hole on the run.

9
00:00:23.680 --> 00:00:26.040
Incredible news from Mars, a

10
00:00:26.040 --> 00:00:28.930
surprisingly active moon, and a, major

11
00:00:28.930 --> 00:00:31.330
leap forward for European spacefl.

12
00:00:31.870 --> 00:00:32.830
Where do we even begin?

13
00:00:33.310 --> 00:00:36.030
Anna: Let's start here on Earth with a big

14
00:00:36.030 --> 00:00:38.630
leadership announcement. It's been confirmed

15
00:00:38.630 --> 00:00:41.270
that billionaire entrepreneur and astronaut

16
00:00:41.270 --> 00:00:43.870
Jared Isaacman will be the next head of

17
00:00:43.870 --> 00:00:44.430
NASA.

18
00:00:44.830 --> 00:00:47.749
Avery: That is huge news. I mean, this is the guy

19
00:00:47.749 --> 00:00:50.390
behind the Inspiration 4 and Polaris dawn

20
00:00:50.390 --> 00:00:52.950
missions. He's not just a funder, he's

21
00:00:52.950 --> 00:00:54.270
actually flown to space.

22
00:00:54.830 --> 00:00:57.550
Anna: Exactly. And that background is what makes

23
00:00:57.550 --> 00:01:00.550
this appointment so fascinating. Isaacman

24
00:01:00.550 --> 00:01:02.910
brings a deep understanding of the commercial

25
00:01:02.910 --> 00:01:05.370
space sector. This signals a potential

26
00:01:05.450 --> 00:01:08.290
acceleration of the partnership between NASA

27
00:01:08.290 --> 00:01:10.930
and private companies like SpaceX, Blue

28
00:01:10.930 --> 00:01:12.170
Origin and others.

29
00:01:12.570 --> 00:01:15.380
Avery: Right. A, shift in focus. So we might

30
00:01:15.380 --> 00:01:18.220
see more commercially driven missions, maybe

31
00:01:18.220 --> 00:01:20.100
faster development cycles for new

32
00:01:20.100 --> 00:01:20.740
technologies.

33
00:01:21.220 --> 00:01:23.820
Anna: That seems to be the expectation. His

34
00:01:23.820 --> 00:01:26.300
supporters believe his entrepreneurial spirit

35
00:01:26.300 --> 00:01:28.620
could Streamline Some of NASA's larger

36
00:01:28.620 --> 00:01:31.540
projects, like the Artemis program. However,

37
00:01:31.780 --> 00:01:33.660
some in the scientific community are

38
00:01:33.660 --> 00:01:36.660
cautiously optimistic, hoping the agency's

39
00:01:36.660 --> 00:01:39.060
core mission of pure scientific research

40
00:01:39.380 --> 00:01:40.900
remains a top priority.

41
00:01:41.300 --> 00:01:44.060
Avery: It's a, balancing act, for sure. It will be

42
00:01:44.060 --> 00:01:45.940
incredibly interesting to see how his

43
00:01:45.940 --> 00:01:48.300
leadership shapes NASA's direction over the

44
00:01:48.300 --> 00:01:49.060
next few years.

45
00:01:49.700 --> 00:01:52.380
Okay, from leadership on Earth, let's head

46
00:01:52.380 --> 00:01:54.900
out to the truly wild frontiers of space.

47
00:01:55.380 --> 00:01:57.750
Anna, you have to tell us about this runaway

48
00:01:57.750 --> 00:01:58.470
black hole.

49
00:01:58.920 --> 00:02:01.080
Anna: This story is just breathtaking.

50
00:02:01.480 --> 00:02:04.160
Astronomers using the James Webb Telescope

51
00:02:04.160 --> 00:02:06.520
have confirmed something they've never seen.

52
00:02:07.240 --> 00:02:10.160
A supermassive black hole weighing as much

53
00:02:10.160 --> 00:02:12.880
as 20 million suns hurtling

54
00:02:12.880 --> 00:02:14.600
through intergalactic space.

55
00:02:15.240 --> 00:02:17.560
Avery: Wow. How fast are we talking?

56
00:02:17.960 --> 00:02:20.680
Anna: It's moving at about 2.2 million

57
00:02:20.840 --> 00:02:23.360
miles per hour. Fast enough to travel from

58
00:02:23.360 --> 00:02:25.960
the Earth to the Moon in about six minutes.

59
00:02:26.620 --> 00:02:29.420
Avery: That is absolutely mind bending. But

60
00:02:29.420 --> 00:02:31.420
that's not even the wildest part, is it?

61
00:02:31.660 --> 00:02:34.460
Anna: Not at all. The most stunning part is what

62
00:02:34.460 --> 00:02:36.760
it's leaving behind. As, this black hole

63
00:02:36.760 --> 00:02:39.560
plows through the gas between galaxies, it's

64
00:02:39.560 --> 00:02:42.159
compressing that material and triggering a

65
00:02:42.159 --> 00:02:44.800
massive wave of star formation. It's

66
00:02:44.800 --> 00:02:47.680
dragging a tail of newborn stars behind it

67
00:02:47.760 --> 00:02:50.640
that is 200,000 light years long.

68
00:02:51.120 --> 00:02:54.080
Avery: 200,000 light years. That's twice

69
00:02:54.080 --> 00:02:56.800
the diameter of our own Milky Way galaxy.

70
00:02:56.960 --> 00:02:59.900
Just a tail of stars. So it's both

71
00:02:59.900 --> 00:03:02.580
a force of destruction and creation at the

72
00:03:02.580 --> 00:03:03.100
same time.

73
00:03:03.500 --> 00:03:06.500
Anna: Precisely. The theory is that this happened

74
00:03:06.500 --> 00:03:09.460
because of a massive cosmic collision. Two

75
00:03:09.460 --> 00:03:11.420
galaxies merged and their central

76
00:03:11.580 --> 00:03:14.340
supermassive black holes began to orbit each

77
00:03:14.340 --> 00:03:16.870
other. Then a, third galaxy joined the

78
00:03:16.870 --> 00:03:19.790
fray and a complex gravitational dance

79
00:03:19.790 --> 00:03:22.310
ejected one of the black holes, sending it

80
00:03:22.310 --> 00:03:24.350
careening out of its home galaxy.

81
00:03:24.750 --> 00:03:27.190
Avery: It's like a gravitational slingshot on a

82
00:03:27.190 --> 00:03:30.030
galactic scale. An incredible discovery,

83
00:03:30.030 --> 00:03:32.270
and what a testament to the power of the

84
00:03:32.270 --> 00:03:34.590
JWST it really is.

85
00:03:35.150 --> 00:03:37.630
Anna: Now let's bring our focus a little closer to

86
00:03:37.630 --> 00:03:40.270
home, to our neighbor Mars, where another

87
00:03:40.430 --> 00:03:42.430
NASA mission is making history.

88
00:03:42.990 --> 00:03:45.710
Avery: Yes, let's talk about the Perseverance Rover.

89
00:03:45.950 --> 00:03:48.550
This machine is just an absolute marathon

90
00:03:48.550 --> 00:03:50.950
runner. NASA recently announced it has

91
00:03:50.950 --> 00:03:53.950
traveled almost 25 miles across the surface

92
00:03:53.950 --> 00:03:54.590
of Mars.

93
00:03:54.890 --> 00:03:56.930
Anna: And after several years in a harsh

94
00:03:56.930 --> 00:03:59.250
environment, it's still in excellent

95
00:03:59.250 --> 00:04:01.650
condition. This mission has been a huge

96
00:04:01.650 --> 00:04:03.690
success for autonomous navigation.

97
00:04:04.010 --> 00:04:06.410
Perseverance is making many of its own

98
00:04:06.410 --> 00:04:08.970
driving decisions to avoid hazards, which

99
00:04:08.970 --> 00:04:11.570
allows it to cover ground much faster than

100
00:04:11.570 --> 00:04:12.410
previous rovers.

101
00:04:12.730 --> 00:04:15.530
Avery: It's an explorer in the truest sense. And

102
00:04:15.530 --> 00:04:17.690
it's not just driving. It's doing some

103
00:04:17.690 --> 00:04:20.410
groundbreaking science. Tell us about the

104
00:04:20.410 --> 00:04:21.290
Margin Unit.

105
00:04:21.740 --> 00:04:24.260
Anna: Right, so Perseverance has been exploring

106
00:04:24.260 --> 00:04:26.780
this area at the edge of Jezero Crater

107
00:04:27.020 --> 00:04:29.380
called the Margin Unit. It's a

108
00:04:29.380 --> 00:04:32.180
geological treasure trove. The rover has been

109
00:04:32.180 --> 00:04:34.980
analyzing rocks rich in olivine, a

110
00:04:34.980 --> 00:04:37.419
mineral that on Earth is often associated

111
00:04:37.419 --> 00:04:38.060
with water.

112
00:04:38.460 --> 00:04:41.460
Avery: Okay, so olivine plus water, that's always an

113
00:04:41.460 --> 00:04:43.660
exciting combination in the search for life.

114
00:04:44.060 --> 00:04:46.820
Anna: Indeed, the data suggests these rocks

115
00:04:46.820 --> 00:04:49.060
interacted with liquid water and carbon

116
00:04:49.060 --> 00:04:51.780
dioxide from the Martian atmosphere over

117
00:04:51.780 --> 00:04:54.120
long periods. By studying these

118
00:04:54.120 --> 00:04:56.720
interactions, scientists can piece together

119
00:04:56.720 --> 00:04:58.760
what the Martian environment was like

120
00:04:58.760 --> 00:05:01.440
billions of years ago and assess whether it

121
00:05:01.440 --> 00:05:03.240
could have supported microbial life.

122
00:05:03.560 --> 00:05:05.720
Avery: And Perseverance has been drilling samples

123
00:05:05.720 --> 00:05:08.000
from these rocks. Right. To eventually bring

124
00:05:08.000 --> 00:05:08.760
back to Earth.

125
00:05:09.159 --> 00:05:11.800
Anna: Yes, it has been collecting a diverse library

126
00:05:11.800 --> 00:05:14.440
of rock cores. The Mars Sample Return

127
00:05:14.440 --> 00:05:16.600
Mission is still in development. But when

128
00:05:16.600 --> 00:05:19.120
those samples finally get into labs here on

129
00:05:19.120 --> 00:05:21.600
Earth, they could fundamentally change our

130
00:05:21.600 --> 00:05:24.080
understanding of Mars and the potential for

131
00:05:24.080 --> 00:05:25.780
life beyond our planet.

132
00:05:25.940 --> 00:05:28.500
Avery: An amazing mission that just keeps on giving.

133
00:05:29.060 --> 00:05:31.940
Alright, let's hop from Mars to our own moon,

134
00:05:31.940 --> 00:05:34.180
which is apparently not the quiet,

135
00:05:34.180 --> 00:05:36.020
unchanging world we thought it was.

136
00:05:36.340 --> 00:05:39.180
Anna: That's right. New high resolution images

137
00:05:39.180 --> 00:05:42.060
from NASA's Lunar Reconnaissance Orbiter, or

138
00:05:42.060 --> 00:05:45.060
LRO, have revealed massive cracks on

139
00:05:45.060 --> 00:05:47.700
the moon's surface. These features are called

140
00:05:47.700 --> 00:05:50.220
grabens, and they're essentially trenches

141
00:05:50.220 --> 00:05:52.260
formed when the crust is pulled apart.

142
00:05:52.760 --> 00:05:55.200
Avery: Okay, so the crust is Fracturing? What's

143
00:05:55.200 --> 00:05:55.800
causing that?

144
00:05:56.200 --> 00:05:58.760
Anna: These particular grabens are located around

145
00:05:58.840 --> 00:06:01.720
Mare Humorum basin, an area that was

146
00:06:01.720 --> 00:06:04.600
once filled with volcanic lava. As this

147
00:06:04.600 --> 00:06:07.400
immense sea of lava cooled and solidified

148
00:06:07.400 --> 00:06:10.120
over millions of years, it contracted.

149
00:06:10.280 --> 00:06:12.880
This contraction put immense stress on the

150
00:06:12.880 --> 00:06:15.600
surrounding crust, causing it to buckle and

151
00:06:15.600 --> 00:06:18.120
fracture, forming these long linear

152
00:06:18.120 --> 00:06:18.670
valleys.

153
00:06:19.220 --> 00:06:21.180
Avery: So this is ancient history then? From when

154
00:06:21.180 --> 00:06:22.900
the Moon was volcanically active?

155
00:06:23.300 --> 00:06:26.100
Anna: Well, this is the surprising part. While the

156
00:06:26.100 --> 00:06:29.020
process started long ago, analysis of the

157
00:06:29.020 --> 00:06:31.380
images shows that some of these grabens are

158
00:06:31.380 --> 00:06:34.220
remarkably young in geological terms. Some

159
00:06:34.220 --> 00:06:36.820
might be less than 50 million years old.

160
00:06:37.300 --> 00:06:39.700
Avery: 50 million years. That's practically

161
00:06:39.700 --> 00:06:42.500
yesterday in geological time. So the Moon's

162
00:06:42.500 --> 00:06:45.100
surface is still actively changing. It's not

163
00:06:45.100 --> 00:06:45.860
a dead rock.

164
00:06:46.360 --> 00:06:49.300
Anna: Exactly. It suggests, the lunar interior is

165
00:06:49.300 --> 00:06:51.740
still cooling and contracting. And these

166
00:06:51.740 --> 00:06:54.420
surface features are the evidence it forces

167
00:06:54.420 --> 00:06:57.420
us to rethink the Moon as a dynamic, evolving

168
00:06:57.500 --> 00:07:00.180
world, which has important implications for

169
00:07:00.180 --> 00:07:02.940
future long term habitats and exploration.

170
00:07:03.340 --> 00:07:04.780
Avery: Absolutely fascinating.

171
00:07:05.180 --> 00:07:08.180
Okay, for a final story, we're back in Earth

172
00:07:08.180 --> 00:07:10.900
orbit celebrating a major milestone for the

173
00:07:10.900 --> 00:07:12.380
European Space Agency.

174
00:07:12.690 --> 00:07:15.530
Anna: Mm, this is a big one for European space

175
00:07:15.530 --> 00:07:18.490
autonomy. Just this week, Europe's brand new

176
00:07:18.490 --> 00:07:21.490
Ariane 6 rocket had its first operational

177
00:07:21.490 --> 00:07:23.730
launch and it was a complete success.

178
00:07:24.290 --> 00:07:26.010
Avery: I know they've been waiting for this for a

179
00:07:26.010 --> 00:07:28.770
long time. After the retirement of Ariane 5,

180
00:07:28.850 --> 00:07:31.010
there was a gap in Europe's independent

181
00:07:31.010 --> 00:07:33.370
launch capability. This must be a huge

182
00:07:33.370 --> 00:07:33.890
relief.

183
00:07:34.210 --> 00:07:36.730
Anna: A massive relief. For the past couple of

184
00:07:36.730 --> 00:07:38.810
years, Europe has had to rely on other

185
00:07:38.810 --> 00:07:41.490
providers, including SpaceX, to launch its

186
00:07:41.490 --> 00:07:44.010
critical satellites. The successful launch of

187
00:07:44.010 --> 00:07:46.670
ARR restores their ability to

188
00:07:46.670 --> 00:07:49.510
independently access space, which is crucial

189
00:07:49.510 --> 00:07:51.870
for both commercial and strategic reasons.

190
00:07:52.270 --> 00:07:53.950
Avery: So what was on this inaugural flight?

191
00:07:54.110 --> 00:07:56.470
Anna: The rocket carried two new satellites for the

192
00:07:56.470 --> 00:07:59.150
Galileo Constellation. This is Europe's

193
00:07:59.150 --> 00:08:01.590
Global Navigation Satellite System, their

194
00:08:01.590 --> 00:08:04.390
equivalent of the American gps. Adding

195
00:08:04.390 --> 00:08:06.910
these new satellites enhances the system's

196
00:08:06.910 --> 00:08:09.550
accuracy, reliability and coverage.

197
00:08:09.950 --> 00:08:11.790
Avery: So this isn't just a win for the rocket

198
00:08:11.790 --> 00:08:13.910
program, but also for the millions of people

199
00:08:13.910 --> 00:08:16.890
who will rely on the Galileo. Everything from

200
00:08:16.890 --> 00:08:19.730
navigating their cars to critical emergency

201
00:08:19.730 --> 00:08:20.090
services.

202
00:08:20.650 --> 00:08:23.130
Anna: That's it. It's a dual victory that

203
00:08:23.130 --> 00:08:25.610
solidifies Europe's position as a major

204
00:08:25.690 --> 00:08:28.030
player in the global space industry. A, ah,

205
00:08:28.130 --> 00:08:29.850
really significant step forward.

206
00:08:30.330 --> 00:08:33.330
Avery: What a fantastic roundup. From new leadership

207
00:08:33.330 --> 00:08:35.810
at NASA to cosmic fugitives and

208
00:08:35.810 --> 00:08:37.930
evolving worlds right in our backyard.

209
00:08:38.170 --> 00:08:40.970
Anna: It just goes to show that there is always

210
00:08:41.050 --> 00:08:43.970
something new to discover. Every day brings

211
00:08:43.970 --> 00:08:46.790
a revelation that reshapes our understanding

212
00:08:46.790 --> 00:08:47.590
of the universe.

213
00:08:47.990 --> 00:08:49.840
Avery: Well said, Anna. that's all the time we have

214
00:08:49.840 --> 00:08:52.160
