Uranus & Neptune's Shocking Makeover, Blue Origin's Next Steps, and Martian Whirlwinds
- Reclassification of Uranus and Neptune: New research from the University of Zurich challenges the long-held belief that Uranus and Neptune are ice giants. Advanced computer models suggest these planets may actually be rock giants, altering our understanding of their formation and evolution. This groundbreaking finding could necessitate a reevaluation of how we classify exoplanets, as well.
- Blue Origin's Upcoming Launch: Blue Origin is set to make headlines with its New Shepard suborbital vehicle, vital for expanding humanity's access to space. Each launch contributes crucial data that enhances safety and prepares for more ambitious missions, including the upcoming New Glenn rocket, which aims to support lunar missions.
- Philosophical Reflections on Humanity's Place: As we explore the cosmos, we confront profound questions about our existence and uniqueness. The search for extraterrestrial life and studies of dark matter and energy drive our understanding of where we fit in the grand cosmic tapestry.
- Dust Devils on Mars: European Space Agency orbiters have mapped over 1,000 dust devils on Mars, revealing they can reach speeds of up to 98 mph. This data is crucial for future Mars missions, helping scientists refine atmospheric models and improve weather forecasts for sustained human presence on the planet.

00:00:00.000 --> 00:00:02.120
Anna: Welcome to Astronomy Daily, your quick dive
1
00:00:02.120 --> 00:00:04.800
into the cosmos with me, Anna and me
2
00:00:04.800 --> 00:00:05.520
Avery.
3
00:00:05.760 --> 00:00:08.000
Avery: We've got some fascinating stories for you
4
00:00:08.000 --> 00:00:10.800
today, from our solar system's mysterious ice
5
00:00:10.800 --> 00:00:13.760
giants, possibly being rock giants, to
6
00:00:13.760 --> 00:00:16.600
Blue Origin's next big launch, and some
7
00:00:16.600 --> 00:00:19.080
mind bending theories about humanity's place
8
00:00:19.080 --> 00:00:20.000
in the universe.
9
00:00:20.480 --> 00:00:22.840
Anna: That's right. Let's kick things off with a
10
00:00:22.840 --> 00:00:25.120
rather surprising reclassification for two of
11
00:00:25.120 --> 00:00:28.030
our own planetary neighbors. You know how we
12
00:00:28.030 --> 00:00:29.990
always refer to Uranus and Neptune as ice
13
00:00:29.990 --> 00:00:32.710
giants? Well, a new study is
14
00:00:32.710 --> 00:00:34.390
challenging that long held belief.
15
00:00:34.630 --> 00:00:36.910
Avery: Yeah, it's pretty wild. Researchers from the
16
00:00:36.910 --> 00:00:39.110
University of Zurich have been digging into
17
00:00:39.110 --> 00:00:41.950
their interior structures using advanced
18
00:00:41.950 --> 00:00:44.790
computer models and existing planetary data.
19
00:00:45.270 --> 00:00:47.670
And what they found suggests these planets
20
00:00:47.670 --> 00:00:50.230
might actually be rock giants instead.
21
00:00:50.630 --> 00:00:52.590
Anna: Indeed, the implications of this study are
22
00:00:52.590 --> 00:00:55.150
quite profound. If Uranus and Neptune are
23
00:00:55.150 --> 00:00:57.630
primarily composed of rock rather than the
24
00:00:57.630 --> 00:01:00.050
icy mixtures we've long assumed, it
25
00:01:00.050 --> 00:01:02.290
significantly alters our understanding of how
26
00:01:02.290 --> 00:01:05.290
these planets formed and evolved. This isn't
27
00:01:05.290 --> 00:01:07.010
just a minor tweak to planetary
28
00:01:07.010 --> 00:01:08.810
classifications. It could necessitate a
29
00:01:08.810 --> 00:01:10.970
complete re evaluation of models of planet
30
00:01:10.970 --> 00:01:13.370
formation in the outer solar system. For
31
00:01:13.370 --> 00:01:15.970
decades, the ice giant moniker
32
00:01:15.970 --> 00:01:18.450
suggested a composition rich in water,
33
00:01:18.610 --> 00:01:21.490
methane and ammonia ices. However, the
34
00:01:21.490 --> 00:01:23.730
University of Zurich's research, led by Dr.
35
00:01:23.730 --> 00:01:26.050
Joachim Sauerkraut, suggests a different
36
00:01:26.050 --> 00:01:28.650
picture. Their advanced computer
37
00:01:28.650 --> 00:01:30.530
simulations, which integrate various
38
00:01:30.530 --> 00:01:32.770
geophysical and astrophysical data,
39
00:01:33.090 --> 00:01:35.130
indicate that the pressure and temperature
40
00:01:35.130 --> 00:01:36.970
conditions within these planets are more
41
00:01:36.970 --> 00:01:39.850
conducive to the formation of silicates
42
00:01:39.850 --> 00:01:42.730
and other rocky materials than previously
43
00:01:42.730 --> 00:01:45.450
thought. This would mean that a substantial
44
00:01:45.450 --> 00:01:47.450
portion of their mass, perhaps even the
45
00:01:47.450 --> 00:01:50.050
majority, is in a solid rocky state deep
46
00:01:50.050 --> 00:01:51.490
beneath their thick atmospheres.
47
00:01:52.240 --> 00:01:54.360
Avery: Absolutely, Anna. Uh, this groundbreaking
48
00:01:54.360 --> 00:01:56.560
research from the University of Zurich,
49
00:01:56.720 --> 00:01:59.480
building on the work of Dr. Joachim Sauer and
50
00:01:59.480 --> 00:02:02.240
his team, suggests a radical departure from
51
00:02:02.240 --> 00:02:05.000
the conventional wisdom. For so long, the
52
00:02:05.000 --> 00:02:07.800
term ice giants has been ingrained in our
53
00:02:07.800 --> 00:02:10.520
astronomical lexicon, painting a picture of
54
00:02:10.520 --> 00:02:13.200
these distant worlds as swirling masses of
55
00:02:13.200 --> 00:02:15.920
frozen water, methane and ammonia.
56
00:02:16.080 --> 00:02:18.320
But if these advanced computer models are
57
00:02:18.320 --> 00:02:20.280
correct, then we're talking about a
58
00:02:20.280 --> 00:02:22.400
significant portion of their internal
59
00:02:22.400 --> 00:02:25.360
structure being made of much denser rocky
60
00:02:25.360 --> 00:02:28.160
material. Imagine a core that's not
61
00:02:28.160 --> 00:02:30.920
just icy sludge, but a solidified
62
00:02:31.240 --> 00:02:34.240
high pressure rock formation hundreds of
63
00:02:34.240 --> 00:02:36.680
thousands of kilometers across. This would
64
00:02:36.680 --> 00:02:38.760
challenge our fundamental understanding of
65
00:02:38.760 --> 00:02:41.000
how planets accumulate material during their
66
00:02:41.000 --> 00:02:43.720
formation. Did they accrete more rocky
67
00:02:43.720 --> 00:02:46.390
planetesimals than previously thought? Or did
68
00:02:46.390 --> 00:02:49.350
some process during their evolution lead to a
69
00:02:49.350 --> 00:02:51.910
differentiation where heavier elements sank
70
00:02:51.910 --> 00:02:54.350
deeper and solidified under immense
71
00:02:54.350 --> 00:02:56.950
pressure? The implications are vast,
72
00:02:57.110 --> 00:02:59.550
not just for Uranus and Neptune, but for
73
00:02:59.550 --> 00:03:02.270
exoplanetary science as well. Many
74
00:03:02.270 --> 00:03:04.230
exoplanets are classified Based on
75
00:03:04.230 --> 00:03:06.350
assumptions Derived from our own solar
76
00:03:06.350 --> 00:03:08.950
system. If our ice giants Are actually
77
00:03:09.110 --> 00:03:11.750
rock giants, Then our classifications for
78
00:03:11.750 --> 00:03:14.190
distant worlds Might also need a serious
79
00:03:14.190 --> 00:03:17.140
reevaluation. It's a truly exciting time
80
00:03:17.140 --> 00:03:19.260
for planetary science. As new data and
81
00:03:19.260 --> 00:03:22.020
sophisticated modeling techniques Continually
82
00:03:22.020 --> 00:03:24.940
push the boundaries of our knowledge. This
83
00:03:24.940 --> 00:03:27.620
re evaluation Of Uranus and Neptune's
84
00:03:27.620 --> 00:03:29.940
composition. Opens up a fascinating new
85
00:03:29.940 --> 00:03:32.940
chapter in planetary science. It forces us to
86
00:03:32.940 --> 00:03:35.780
reconsider the very definition Of a giant
87
00:03:35.780 --> 00:03:38.300
planet. And how these colossal celestial
88
00:03:38.300 --> 00:03:40.880
bodies are formed. Traditionally, married
89
00:03:41.030 --> 00:03:43.590
models of planetary formation Focus on two
90
00:03:43.590 --> 00:03:46.470
main the core accretion, uh, model,
91
00:03:46.550 --> 00:03:48.870
Where a solid core forms first and then
92
00:03:48.870 --> 00:03:51.510
attracts gas, and the disk instability
93
00:03:51.670 --> 00:03:54.110
model, where portions of the protoplanetary
94
00:03:54.110 --> 00:03:56.989
disk collapse directly. If Uranus and
95
00:03:56.989 --> 00:03:59.670
Neptune are primarily rocky, it might
96
00:03:59.670 --> 00:04:02.230
suggest A more robust role for rocky
97
00:04:02.230 --> 00:04:05.190
planetesimals in their formation. Or perhaps
98
00:04:05.190 --> 00:04:07.450
a different evolutionary track where
99
00:04:07.450 --> 00:04:09.610
significant amounts of lighter elements Were
100
00:04:09.610 --> 00:04:12.570
lost over time. This could also shed light
101
00:04:12.570 --> 00:04:14.970
on the diversity of exoplanets we're
102
00:04:14.970 --> 00:04:17.810
discovering. Some exoplanets Classified as
103
00:04:17.810 --> 00:04:20.210
mini Neptunes or super Earths. Could
104
00:04:20.210 --> 00:04:22.330
potentially have compositions similar to
105
00:04:22.330 --> 00:04:25.250
these newly theorized rock giants. Blurring
106
00:04:25.250 --> 00:04:27.450
the lines between these categories. The
107
00:04:27.450 --> 00:04:29.650
implications are truly far reaching,
108
00:04:29.890 --> 00:04:32.290
Extending beyond our solar system to the
109
00:04:32.290 --> 00:04:34.490
broader understanding of planet formation
110
00:04:34.490 --> 00:04:37.430
across the galaxy. It's a testament to
111
00:04:37.430 --> 00:04:40.110
the dynamic nature of scientific discovery.
112
00:04:40.270 --> 00:04:42.750
Where even long held beliefs about our cosmic
113
00:04:42.750 --> 00:04:45.230
neighbors can be challenged and refined by
114
00:04:45.230 --> 00:04:47.350
new data and innovative theoretical
115
00:04:47.350 --> 00:04:47.950
frameworks.
116
00:04:48.590 --> 00:04:50.870
Anna: Now let's shift our gaze from the depths of
117
00:04:50.870 --> 00:04:53.790
planetary interiors to the exciting frontiers
118
00:04:53.790 --> 00:04:56.510
of commercial spaceflight. Blue Origin,
119
00:04:56.590 --> 00:04:59.470
Jeff Bezos's aerospace company, Is once
120
00:04:59.470 --> 00:05:01.430
again making headlines with its preparations
121
00:05:01.430 --> 00:05:03.960
for another significant launch. These
122
00:05:03.960 --> 00:05:06.440
missions, while often appearing routine to
123
00:05:06.440 --> 00:05:08.920
the casual observer, Are critical steps in
124
00:05:08.920 --> 00:05:11.720
expanding humanity's access to space, Pushing
125
00:05:11.720 --> 00:05:14.200
the boundaries of technology, and ultimately
126
00:05:14.280 --> 00:05:17.040
making space travel more accessible. Blue
127
00:05:17.040 --> 00:05:19.280
Origin's New Shepard suborbital vehicle has
128
00:05:19.280 --> 00:05:21.280
been a workhorse for short trips to the edge
129
00:05:21.280 --> 00:05:23.920
of space, Carrying both scientific payloads
130
00:05:23.920 --> 00:05:26.560
and private astronauts. Each launch provides
131
00:05:26.560 --> 00:05:29.560
invaluable data, Allowing engineers to refine
132
00:05:29.560 --> 00:05:32.420
systems and enhance safety and prepare for
133
00:05:32.420 --> 00:05:34.900
even more ambitious endeavors. Like their new
134
00:05:34.900 --> 00:05:37.340
Glenn Orbital rocket, which aims to deliver
135
00:05:37.340 --> 00:05:39.620
heavier payloads to higher orbits and
136
00:05:39.620 --> 00:05:42.140
eventually support lunar missions. The
137
00:05:42.140 --> 00:05:43.820
iterative nature of these launches is
138
00:05:43.820 --> 00:05:46.419
essential. Every flight, even
139
00:05:46.419 --> 00:05:48.700
seemingly minor ones, Contributes to a
140
00:05:48.700 --> 00:05:50.660
growing body of knowledge that fuels future
141
00:05:50.660 --> 00:05:53.060
innovations and brings us closer to a
142
00:05:53.060 --> 00:05:55.950
sustainable presence beyond Earth. We
143
00:05:55.950 --> 00:05:57.550
often focus on the spectacle of human
144
00:05:57.550 --> 00:06:00.310
spaceflight. But the unsung heroes
145
00:06:00.550 --> 00:06:02.950
are often the scientific experiments and
146
00:06:02.950 --> 00:06:04.990
technological demonstrations that ride
147
00:06:04.990 --> 00:06:07.390
alongside gathering data in
148
00:06:07.390 --> 00:06:09.950
microgravity and testing new systems that
149
00:06:09.950 --> 00:06:12.030
will power the next generation of space
150
00:06:12.030 --> 00:06:12.710
exploration.
151
00:06:13.030 --> 00:06:16.030
Avery: Indeed, Anna Blue Origin's strategy, much
152
00:06:16.030 --> 00:06:18.110
like that of other private space ventures, is
153
00:06:18.110 --> 00:06:20.310
a testament to the power of incremental
154
00:06:20.310 --> 00:06:23.200
progress. Each New Shepard flight, whether
155
00:06:23.200 --> 00:06:25.160
it's sending scientific instruments to
156
00:06:25.160 --> 00:06:27.600
conduct microgravity research or taking
157
00:06:27.600 --> 00:06:30.080
private citizens on a brief but unforgettable
158
00:06:30.080 --> 00:06:32.280
journey to the Karman Line, is a building
159
00:06:32.280 --> 00:06:35.160
block. These suborbital hops are not just
160
00:06:35.160 --> 00:06:37.399
about spectacle. They are vital testing
161
00:06:37.399 --> 00:06:40.360
grounds. They allow engineers to gather real
162
00:06:40.360 --> 00:06:42.480
world data on everything from propulsion
163
00:06:42.480 --> 00:06:45.240
systems and structural integrity to crew
164
00:06:45.240 --> 00:06:47.200
safety protocols and landing precision.
165
00:06:48.410 --> 00:06:50.490
This data is then fed back into the design
166
00:06:50.490 --> 00:06:52.370
and development of their more ambitious
167
00:06:52.370 --> 00:06:55.330
projects, Particularly the massive New Glenn
168
00:06:55.330 --> 00:06:58.130
Orbital rocket. New Glenn, with its
169
00:06:58.130 --> 00:07:00.170
immense payload capacity, is designed to
170
00:07:00.170 --> 00:07:02.610
launch satellites, interplanetary probes, and
171
00:07:02.610 --> 00:07:04.810
even components for future lunar landers and
172
00:07:04.810 --> 00:07:07.730
orbital habitats. The vision extends
173
00:07:07.730 --> 00:07:10.410
far beyond just getting to space. It's about
174
00:07:10.410 --> 00:07:12.330
creating a sustainable, accessible
175
00:07:12.330 --> 00:07:14.410
infrastructure for human activity in the
176
00:07:14.410 --> 00:07:17.090
cosmos. And it's not just about the rockets
177
00:07:17.090 --> 00:07:19.770
themselves. Blue Origin is also deeply
178
00:07:19.770 --> 00:07:22.050
involved in developing engines such as the
179
00:07:22.050 --> 00:07:24.970
B4, which powers both New Glenn and
180
00:07:24.970 --> 00:07:27.130
United Launch Alliance's Vulcan Centaur
181
00:07:27.130 --> 00:07:29.890
rocket. This kind of intercompany
182
00:07:29.890 --> 00:07:32.290
collaboration and shared technology further
183
00:07:32.290 --> 00:07:34.370
accelerates the pace of innovation in the
184
00:07:34.370 --> 00:07:37.330
space industry. It's a truly exciting era
185
00:07:37.330 --> 00:07:39.650
where the dream of widespread space access
186
00:07:40.130 --> 00:07:42.450
is slowly but surely becoming a tangible
187
00:07:42.450 --> 00:07:45.190
reality. Driven by these relentless efforts
188
00:07:45.190 --> 00:07:47.230
and engineering and iterative testing.
189
00:07:47.790 --> 00:07:49.910
Anna: Absolutely, Avery. The commercial space
190
00:07:49.910 --> 00:07:51.830
sector, spearheaded by companies like Blue
191
00:07:51.830 --> 00:07:53.950
Origin, isn't just about sending rockets
192
00:07:53.950 --> 00:07:56.310
skyward. It's about democratizing access to
193
00:07:56.310 --> 00:07:59.070
space and fostering a new era of innovation.
194
00:07:59.550 --> 00:08:01.910
Think about the ripple effect. As launch
195
00:08:01.910 --> 00:08:04.750
costs decrease and capabilities expand, more
196
00:08:04.750 --> 00:08:06.990
research can be conducted in microgravity,
197
00:08:07.150 --> 00:08:09.700
new industries can emerge, and eventually
198
00:08:09.940 --> 00:08:11.860
more people will have the opportunity to
199
00:08:11.860 --> 00:08:14.780
experience space firsthand. This isn't just a
200
00:08:14.780 --> 00:08:17.380
distant dream. It's a tangible future being
201
00:08:17.380 --> 00:08:19.940
built with each successful mission. The
202
00:08:19.940 --> 00:08:22.140
pursuit of sustainable space infrastructure,
203
00:08:22.140 --> 00:08:25.059
from orbital hotels to lunar bases, relies
204
00:08:25.059 --> 00:08:27.220
heavily on the foundational work being done
205
00:08:27.220 --> 00:08:30.020
now. Blue Origin's vision Grata
206
00:08:30.020 --> 00:08:32.820
team ferocity, step by step, ferociously,
207
00:08:32.820 --> 00:08:35.060
perfectly encapsulates this methodical yet
208
00:08:35.060 --> 00:08:37.210
ambitious approach. They are not only
209
00:08:37.210 --> 00:08:39.730
building rockets, but also developing the
210
00:08:39.730 --> 00:08:41.690
underlying technologies that will make
211
00:08:41.690 --> 00:08:44.010
sustained human presence in space a reality.
212
00:08:44.250 --> 00:08:46.730
This includes advanced engines, reusable
213
00:08:46.730 --> 00:08:49.410
launch systems, and even conceptual designs
214
00:08:49.410 --> 00:08:50.370
for space habitats.
215
00:08:50.370 --> 00:08:52.690
It's a long term game, but one with profound
216
00:08:52.690 --> 00:08:55.290
implications for our species. As we look
217
00:08:55.290 --> 00:08:57.210
outwards, the very act of exploring and
218
00:08:57.210 --> 00:08:59.130
expanding our reach into the cosmos
219
00:08:59.530 --> 00:09:01.450
Inevitably leads us to ponder our own
220
00:09:01.450 --> 00:09:04.220
existence, our origins, and our ultimate
221
00:09:04.220 --> 00:09:06.820
destiny. It's a journey that forces us to
222
00:09:06.820 --> 00:09:08.980
confront Some of the most profound mind
223
00:09:08.980 --> 00:09:10.900
bending theories about humanity's place in
224
00:09:10.900 --> 00:09:13.780
the universe. From the vastness of the
225
00:09:13.780 --> 00:09:16.140
cosmos to the intricate dance of fundamental
226
00:09:16.140 --> 00:09:18.940
particles, the universe seems to whisper
227
00:09:18.940 --> 00:09:21.620
questions about our significance, our
228
00:09:21.620 --> 00:09:23.900
uniqueness, and whether we are truly alone.
229
00:09:24.700 --> 00:09:27.100
These are not merely philosophical musings,
230
00:09:27.340 --> 00:09:29.980
but deeply scientific inquiries that drive
231
00:09:29.980 --> 00:09:32.580
much of our astrophysical research. The
232
00:09:32.580 --> 00:09:34.820
search for extraterrestrial life, the study
233
00:09:34.820 --> 00:09:37.340
of exoplanets, and the exploration of dark
234
00:09:37.340 --> 00:09:40.100
matter and dark energy all contribute to our
235
00:09:40.100 --> 00:09:42.180
evolving understanding of, uh, where we fit
236
00:09:42.180 --> 00:09:45.100
in the grand cosmic tapestry. It's a
237
00:09:45.100 --> 00:09:47.460
humbling, yet exhilarating realization that
238
00:09:47.460 --> 00:09:49.340
our journey into space Is intrinsically
239
00:09:49.340 --> 00:09:52.340
linked to our quest for self knowledge. Each
240
00:09:52.340 --> 00:09:55.180
discovery, whether it's a new exoplanet Or a
241
00:09:55.180 --> 00:09:57.020
deeper insight into the early universe,
242
00:09:57.420 --> 00:09:59.780
Reframes our perspective and challenges our
243
00:09:59.780 --> 00:10:02.140
anthropocentric views, Pushing us to imagine
244
00:10:02.140 --> 00:10:04.050
possibilities Far beyond our terrestrial
245
00:10:04.280 --> 00:10:04.840
confines.
246
00:10:05.720 --> 00:10:08.200
Shifting gears from philosophical quests,
247
00:10:08.520 --> 00:10:10.360
let's talk about some fascinating new
248
00:10:10.360 --> 00:10:12.920
findings from Mars. European Space
249
00:10:12.920 --> 00:10:15.320
Agency orbiters, Mars Express and
250
00:10:15.320 --> 00:10:18.160
ExoMars Trace Gas Orbiter have been busy
251
00:10:18.160 --> 00:10:20.040
Mapping dust devils on the red planet.
252
00:10:20.360 --> 00:10:23.000
Avery: That's right, anna. Uh, over two decades,
253
00:10:23.000 --> 00:10:24.920
researchers tracked an astounding
254
00:10:24.920 --> 00:10:27.920
1,039 dust devils. And what
255
00:10:27.920 --> 00:10:30.470
they found is pretty remarkable. These
256
00:10:30.470 --> 00:10:33.110
Martian whirlwinds Can actually reach speeds
257
00:10:33.110 --> 00:10:35.470
up to 98 miles per hour, or
258
00:10:35.470 --> 00:10:38.430
158 kilometers per hour, which is
259
00:10:38.430 --> 00:10:40.270
much faster than we previously thought.
260
00:10:40.830 --> 00:10:42.790
Anna: And this isn't just a cool fact. These
261
00:10:42.790 --> 00:10:44.990
findings are incredibly important for future
262
00:10:44.990 --> 00:10:47.590
Mars missions. Understanding how these dust
263
00:10:47.590 --> 00:10:49.710
devils behave Helps us plan better,
264
00:10:50.270 --> 00:10:52.230
Especially when it comes to the impact of
265
00:10:52.230 --> 00:10:54.910
dust on rover solar panels and the selection
266
00:10:54.910 --> 00:10:56.130
of safe landing sites.
267
00:10:56.680 --> 00:10:59.680
Avery: It's also a testament to innovative tech. As
268
00:10:59.680 --> 00:11:01.960
artificial intelligence played a key role,
269
00:11:02.520 --> 00:11:05.040
AI was used to analyze how these dust
270
00:11:05.040 --> 00:11:08.040
devils Shifted between frames, Essentially
271
00:11:08.040 --> 00:11:10.000
turning what might have been dismissed as
272
00:11:10.000 --> 00:11:12.920
image noise into valuable scientific
273
00:11:12.920 --> 00:11:15.080
measurements of wind speed and direction.
274
00:11:15.240 --> 00:11:17.120
Anna: The data also revealed some interesting
275
00:11:17.120 --> 00:11:20.040
patterns. Martian dust devils are most
276
00:11:20.040 --> 00:11:22.000
frequent during the daytime in spring and
277
00:11:22.000 --> 00:11:24.550
summer, Typically peaking between late
278
00:11:24.550 --> 00:11:27.110
morning and early afternoon. And they usually
279
00:11:27.110 --> 00:11:28.310
last only a few minutes.
280
00:11:28.790 --> 00:11:31.230
Avery: What's particularly significant, though, is
281
00:11:31.230 --> 00:11:33.750
how Martian dust behaves Compared to Earth.
282
00:11:34.070 --> 00:11:37.030
Here, dust settles relatively quickly, but
283
00:11:37.030 --> 00:11:39.430
on Mars, dust can linger for months.
284
00:11:39.990 --> 00:11:42.470
This makes understanding its uplift mechanism
285
00:11:42.470 --> 00:11:44.790
critical for predicting the planet's weather
286
00:11:44.790 --> 00:11:46.710
and even its long term climate.
287
00:11:47.110 --> 00:11:50.070
Anna: Exactly. This new global data is invaluable.
288
00:11:50.350 --> 00:11:52.470
It's helping scientists refine atmospheric
289
00:11:52.470 --> 00:11:54.470
models and significantly improve future
290
00:11:54.470 --> 00:11:57.150
weather forecasts for Mars, which is crucial
291
00:11:57.150 --> 00:11:58.950
as we look towards more sustained human
292
00:11:58.950 --> 00:11:59.710
presence there.
293
00:11:59.870 --> 00:12:02.150
Avery: And it's this profound connection, Anna,
294
00:12:02.150 --> 00:12:04.790
between our exploration of the cosmos and our
295
00:12:04.790 --> 00:12:07.070
internal philosophical quests that makes
296
00:12:07.070 --> 00:12:09.950
astronomy so endlessly captivating. Every
297
00:12:09.950 --> 00:12:12.710
new mission, every telescope image, every
298
00:12:12.710 --> 00:12:15.150
theoretical breakthrough serves not just to
299
00:12:15.150 --> 00:12:17.710
fill our scientific journals, but to enrich
300
00:12:17.710 --> 00:12:20.130
our human experience. It makes us question,
301
00:12:20.530 --> 00:12:23.410
imagine, and ultimately understand ourselves
302
00:12:23.410 --> 00:12:25.930
better in the grand scheme of things. From
303
00:12:25.930 --> 00:12:28.170
the subatomic to the supercluster, the
304
00:12:28.170 --> 00:12:31.090
universe is a symphony of mysteries. And we,
305
00:12:31.170 --> 00:12:33.570
as curious observers, are both part of the
306
00:12:33.570 --> 00:12:36.530
music and its eager listeners. As we continue
307
00:12:36.530 --> 00:12:38.770
to delve into the vastness, we're not just
308
00:12:38.770 --> 00:12:40.970
finding answers about distant stars and
309
00:12:40.970 --> 00:12:43.930
galaxies, but also discovering more about the
310
00:12:43.930 --> 00:12:46.560
intricate, evolving story of life itself and.
311
00:12:46.710 --> 00:12:48.870
And its potential, both here on Earth and
312
00:12:48.870 --> 00:12:51.590
perhaps far beyond. This ongoing
313
00:12:51.590 --> 00:12:54.110
dialogue between the known and the unknown is
314
00:12:54.110 --> 00:12:56.670
the very essence of discovery, constantly
315
00:12:56.670 --> 00:12:58.990
inviting us to expand our perceptions of
316
00:12:58.990 --> 00:12:59.750
what's possible.
317
00:13:00.790 --> 00:13:02.869
Anna: And that's it for today. Thank you for coming
318
00:13:02.869 --> 00:13:05.310
along with us on our cosmic journey. Join us
319
00:13:05.310 --> 00:13:07.070
again tomorrow for more insights into our
320
00:13:07.070 --> 00:13:09.270
incredible universe on Astronomy Daily.
321
00:13:09.830 --> 00:13:11.430
Until then, keep looking up.
322
00:13:14.460 --> 00:13:15.740
: The stories we told.
323
00:13:20.230 --> 00:13:20.250
Avery: Mhm.
324
00:13:22.460 --> 00:13:23.100
: Stories
325
00:13:30.940 --> 00:13:31.580
we told.
326
00:13:34.740 --> 00:13:34.900
Avery: You.
0
00:00:00.000 --> 00:00:02.120
Anna: Welcome to Astronomy Daily, your quick dive
1
00:00:02.120 --> 00:00:04.800
into the cosmos with me, Anna and me
2
00:00:04.800 --> 00:00:05.520
Avery.
3
00:00:05.760 --> 00:00:08.000
Avery: We've got some fascinating stories for you
4
00:00:08.000 --> 00:00:10.800
today, from our solar system's mysterious ice
5
00:00:10.800 --> 00:00:13.760
giants, possibly being rock giants, to
6
00:00:13.760 --> 00:00:16.600
Blue Origin's next big launch, and some
7
00:00:16.600 --> 00:00:19.080
mind bending theories about humanity's place
8
00:00:19.080 --> 00:00:20.000
in the universe.
9
00:00:20.480 --> 00:00:22.840
Anna: That's right. Let's kick things off with a
10
00:00:22.840 --> 00:00:25.120
rather surprising reclassification for two of
11
00:00:25.120 --> 00:00:28.030
our own planetary neighbors. You know how we
12
00:00:28.030 --> 00:00:29.990
always refer to Uranus and Neptune as ice
13
00:00:29.990 --> 00:00:32.710
giants? Well, a new study is
14
00:00:32.710 --> 00:00:34.390
challenging that long held belief.
15
00:00:34.630 --> 00:00:36.910
Avery: Yeah, it's pretty wild. Researchers from the
16
00:00:36.910 --> 00:00:39.110
University of Zurich have been digging into
17
00:00:39.110 --> 00:00:41.950
their interior structures using advanced
18
00:00:41.950 --> 00:00:44.790
computer models and existing planetary data.
19
00:00:45.270 --> 00:00:47.670
And what they found suggests these planets
20
00:00:47.670 --> 00:00:50.230
might actually be rock giants instead.
21
00:00:50.630 --> 00:00:52.590
Anna: Indeed, the implications of this study are
22
00:00:52.590 --> 00:00:55.150
quite profound. If Uranus and Neptune are
23
00:00:55.150 --> 00:00:57.630
primarily composed of rock rather than the
24
00:00:57.630 --> 00:01:00.050
icy mixtures we've long assumed, it
25
00:01:00.050 --> 00:01:02.290
significantly alters our understanding of how
26
00:01:02.290 --> 00:01:05.290
these planets formed and evolved. This isn't
27
00:01:05.290 --> 00:01:07.010
just a minor tweak to planetary
28
00:01:07.010 --> 00:01:08.810
classifications. It could necessitate a
29
00:01:08.810 --> 00:01:10.970
complete re evaluation of models of planet
30
00:01:10.970 --> 00:01:13.370
formation in the outer solar system. For
31
00:01:13.370 --> 00:01:15.970
decades, the ice giant moniker
32
00:01:15.970 --> 00:01:18.450
suggested a composition rich in water,
33
00:01:18.610 --> 00:01:21.490
methane and ammonia ices. However, the
34
00:01:21.490 --> 00:01:23.730
University of Zurich's research, led by Dr.
35
00:01:23.730 --> 00:01:26.050
Joachim Sauerkraut, suggests a different
36
00:01:26.050 --> 00:01:28.650
picture. Their advanced computer
37
00:01:28.650 --> 00:01:30.530
simulations, which integrate various
38
00:01:30.530 --> 00:01:32.770
geophysical and astrophysical data,
39
00:01:33.090 --> 00:01:35.130
indicate that the pressure and temperature
40
00:01:35.130 --> 00:01:36.970
conditions within these planets are more
41
00:01:36.970 --> 00:01:39.850
conducive to the formation of silicates
42
00:01:39.850 --> 00:01:42.730
and other rocky materials than previously
43
00:01:42.730 --> 00:01:45.450
thought. This would mean that a substantial
44
00:01:45.450 --> 00:01:47.450
portion of their mass, perhaps even the
45
00:01:47.450 --> 00:01:50.050
majority, is in a solid rocky state deep
46
00:01:50.050 --> 00:01:51.490
beneath their thick atmospheres.
47
00:01:52.240 --> 00:01:54.360
Avery: Absolutely, Anna. Uh, this groundbreaking
48
00:01:54.360 --> 00:01:56.560
research from the University of Zurich,
49
00:01:56.720 --> 00:01:59.480
building on the work of Dr. Joachim Sauer and
50
00:01:59.480 --> 00:02:02.240
his team, suggests a radical departure from
51
00:02:02.240 --> 00:02:05.000
the conventional wisdom. For so long, the
52
00:02:05.000 --> 00:02:07.800
term ice giants has been ingrained in our
53
00:02:07.800 --> 00:02:10.520
astronomical lexicon, painting a picture of
54
00:02:10.520 --> 00:02:13.200
these distant worlds as swirling masses of
55
00:02:13.200 --> 00:02:15.920
frozen water, methane and ammonia.
56
00:02:16.080 --> 00:02:18.320
But if these advanced computer models are
57
00:02:18.320 --> 00:02:20.280
correct, then we're talking about a
58
00:02:20.280 --> 00:02:22.400
significant portion of their internal
59
00:02:22.400 --> 00:02:25.360
structure being made of much denser rocky
60
00:02:25.360 --> 00:02:28.160
material. Imagine a core that's not
61
00:02:28.160 --> 00:02:30.920
just icy sludge, but a solidified
62
00:02:31.240 --> 00:02:34.240
high pressure rock formation hundreds of
63
00:02:34.240 --> 00:02:36.680
thousands of kilometers across. This would
64
00:02:36.680 --> 00:02:38.760
challenge our fundamental understanding of
65
00:02:38.760 --> 00:02:41.000
how planets accumulate material during their
66
00:02:41.000 --> 00:02:43.720
formation. Did they accrete more rocky
67
00:02:43.720 --> 00:02:46.390
planetesimals than previously thought? Or did
68
00:02:46.390 --> 00:02:49.350
some process during their evolution lead to a
69
00:02:49.350 --> 00:02:51.910
differentiation where heavier elements sank
70
00:02:51.910 --> 00:02:54.350
deeper and solidified under immense
71
00:02:54.350 --> 00:02:56.950
pressure? The implications are vast,
72
00:02:57.110 --> 00:02:59.550
not just for Uranus and Neptune, but for
73
00:02:59.550 --> 00:03:02.270
exoplanetary science as well. Many
74
00:03:02.270 --> 00:03:04.230
exoplanets are classified Based on
75
00:03:04.230 --> 00:03:06.350
assumptions Derived from our own solar
76
00:03:06.350 --> 00:03:08.950
system. If our ice giants Are actually
77
00:03:09.110 --> 00:03:11.750
rock giants, Then our classifications for
78
00:03:11.750 --> 00:03:14.190
distant worlds Might also need a serious
79
00:03:14.190 --> 00:03:17.140
reevaluation. It's a truly exciting time
80
00:03:17.140 --> 00:03:19.260
for planetary science. As new data and
81
00:03:19.260 --> 00:03:22.020
sophisticated modeling techniques Continually
82
00:03:22.020 --> 00:03:24.940
push the boundaries of our knowledge. This
83
00:03:24.940 --> 00:03:27.620
re evaluation Of Uranus and Neptune's
84
00:03:27.620 --> 00:03:29.940
composition. Opens up a fascinating new
85
00:03:29.940 --> 00:03:32.940
chapter in planetary science. It forces us to
86
00:03:32.940 --> 00:03:35.780
reconsider the very definition Of a giant
87
00:03:35.780 --> 00:03:38.300
planet. And how these colossal celestial
88
00:03:38.300 --> 00:03:40.880
bodies are formed. Traditionally, married
89
00:03:41.030 --> 00:03:43.590
models of planetary formation Focus on two
90
00:03:43.590 --> 00:03:46.470
main the core accretion, uh, model,
91
00:03:46.550 --> 00:03:48.870
Where a solid core forms first and then
92
00:03:48.870 --> 00:03:51.510
attracts gas, and the disk instability
93
00:03:51.670 --> 00:03:54.110
model, where portions of the protoplanetary
94
00:03:54.110 --> 00:03:56.989
disk collapse directly. If Uranus and
95
00:03:56.989 --> 00:03:59.670
Neptune are primarily rocky, it might
96
00:03:59.670 --> 00:04:02.230
suggest A more robust role for rocky
97
00:04:02.230 --> 00:04:05.190
planetesimals in their formation. Or perhaps
98
00:04:05.190 --> 00:04:07.450
a different evolutionary track where
99
00:04:07.450 --> 00:04:09.610
significant amounts of lighter elements Were
100
00:04:09.610 --> 00:04:12.570
lost over time. This could also shed light
101
00:04:12.570 --> 00:04:14.970
on the diversity of exoplanets we're
102
00:04:14.970 --> 00:04:17.810
discovering. Some exoplanets Classified as
103
00:04:17.810 --> 00:04:20.210
mini Neptunes or super Earths. Could
104
00:04:20.210 --> 00:04:22.330
potentially have compositions similar to
105
00:04:22.330 --> 00:04:25.250
these newly theorized rock giants. Blurring
106
00:04:25.250 --> 00:04:27.450
the lines between these categories. The
107
00:04:27.450 --> 00:04:29.650
implications are truly far reaching,
108
00:04:29.890 --> 00:04:32.290
Extending beyond our solar system to the
109
00:04:32.290 --> 00:04:34.490
broader understanding of planet formation
110
00:04:34.490 --> 00:04:37.430
across the galaxy. It's a testament to
111
00:04:37.430 --> 00:04:40.110
the dynamic nature of scientific discovery.
112
00:04:40.270 --> 00:04:42.750
Where even long held beliefs about our cosmic
113
00:04:42.750 --> 00:04:45.230
neighbors can be challenged and refined by
114
00:04:45.230 --> 00:04:47.350
new data and innovative theoretical
115
00:04:47.350 --> 00:04:47.950
frameworks.
116
00:04:48.590 --> 00:04:50.870
Anna: Now let's shift our gaze from the depths of
117
00:04:50.870 --> 00:04:53.790
planetary interiors to the exciting frontiers
118
00:04:53.790 --> 00:04:56.510
of commercial spaceflight. Blue Origin,
119
00:04:56.590 --> 00:04:59.470
Jeff Bezos's aerospace company, Is once
120
00:04:59.470 --> 00:05:01.430
again making headlines with its preparations
121
00:05:01.430 --> 00:05:03.960
for another significant launch. These
122
00:05:03.960 --> 00:05:06.440
missions, while often appearing routine to
123
00:05:06.440 --> 00:05:08.920
the casual observer, Are critical steps in
124
00:05:08.920 --> 00:05:11.720
expanding humanity's access to space, Pushing
125
00:05:11.720 --> 00:05:14.200
the boundaries of technology, and ultimately
126
00:05:14.280 --> 00:05:17.040
making space travel more accessible. Blue
127
00:05:17.040 --> 00:05:19.280
Origin's New Shepard suborbital vehicle has
128
00:05:19.280 --> 00:05:21.280
been a workhorse for short trips to the edge
129
00:05:21.280 --> 00:05:23.920
of space, Carrying both scientific payloads
130
00:05:23.920 --> 00:05:26.560
and private astronauts. Each launch provides
131
00:05:26.560 --> 00:05:29.560
invaluable data, Allowing engineers to refine
132
00:05:29.560 --> 00:05:32.420
systems and enhance safety and prepare for
133
00:05:32.420 --> 00:05:34.900
even more ambitious endeavors. Like their new
134
00:05:34.900 --> 00:05:37.340
Glenn Orbital rocket, which aims to deliver
135
00:05:37.340 --> 00:05:39.620
heavier payloads to higher orbits and
136
00:05:39.620 --> 00:05:42.140
eventually support lunar missions. The
137
00:05:42.140 --> 00:05:43.820
iterative nature of these launches is
138
00:05:43.820 --> 00:05:46.419
essential. Every flight, even
139
00:05:46.419 --> 00:05:48.700
seemingly minor ones, Contributes to a
140
00:05:48.700 --> 00:05:50.660
growing body of knowledge that fuels future
141
00:05:50.660 --> 00:05:53.060
innovations and brings us closer to a
142
00:05:53.060 --> 00:05:55.950
sustainable presence beyond Earth. We
143
00:05:55.950 --> 00:05:57.550
often focus on the spectacle of human
144
00:05:57.550 --> 00:06:00.310
spaceflight. But the unsung heroes
145
00:06:00.550 --> 00:06:02.950
are often the scientific experiments and
146
00:06:02.950 --> 00:06:04.990
technological demonstrations that ride
147
00:06:04.990 --> 00:06:07.390
alongside gathering data in
148
00:06:07.390 --> 00:06:09.950
microgravity and testing new systems that
149
00:06:09.950 --> 00:06:12.030
will power the next generation of space
150
00:06:12.030 --> 00:06:12.710
exploration.
151
00:06:13.030 --> 00:06:16.030
Avery: Indeed, Anna Blue Origin's strategy, much
152
00:06:16.030 --> 00:06:18.110
like that of other private space ventures, is
153
00:06:18.110 --> 00:06:20.310
a testament to the power of incremental
154
00:06:20.310 --> 00:06:23.200
progress. Each New Shepard flight, whether
155
00:06:23.200 --> 00:06:25.160
it's sending scientific instruments to
156
00:06:25.160 --> 00:06:27.600
conduct microgravity research or taking
157
00:06:27.600 --> 00:06:30.080
private citizens on a brief but unforgettable
158
00:06:30.080 --> 00:06:32.280
journey to the Karman Line, is a building
159
00:06:32.280 --> 00:06:35.160
block. These suborbital hops are not just
160
00:06:35.160 --> 00:06:37.399
about spectacle. They are vital testing
161
00:06:37.399 --> 00:06:40.360
grounds. They allow engineers to gather real
162
00:06:40.360 --> 00:06:42.480
world data on everything from propulsion
163
00:06:42.480 --> 00:06:45.240
systems and structural integrity to crew
164
00:06:45.240 --> 00:06:47.200
safety protocols and landing precision.
165
00:06:48.410 --> 00:06:50.490
This data is then fed back into the design
166
00:06:50.490 --> 00:06:52.370
and development of their more ambitious
167
00:06:52.370 --> 00:06:55.330
projects, Particularly the massive New Glenn
168
00:06:55.330 --> 00:06:58.130
Orbital rocket. New Glenn, with its
169
00:06:58.130 --> 00:07:00.170
immense payload capacity, is designed to
170
00:07:00.170 --> 00:07:02.610
launch satellites, interplanetary probes, and
171
00:07:02.610 --> 00:07:04.810
even components for future lunar landers and
172
00:07:04.810 --> 00:07:07.730
orbital habitats. The vision extends
173
00:07:07.730 --> 00:07:10.410
far beyond just getting to space. It's about
174
00:07:10.410 --> 00:07:12.330
creating a sustainable, accessible
175
00:07:12.330 --> 00:07:14.410
infrastructure for human activity in the
176
00:07:14.410 --> 00:07:17.090
cosmos. And it's not just about the rockets
177
00:07:17.090 --> 00:07:19.770
themselves. Blue Origin is also deeply
178
00:07:19.770 --> 00:07:22.050
involved in developing engines such as the
179
00:07:22.050 --> 00:07:24.970
B4, which powers both New Glenn and
180
00:07:24.970 --> 00:07:27.130
United Launch Alliance's Vulcan Centaur
181
00:07:27.130 --> 00:07:29.890
rocket. This kind of intercompany
182
00:07:29.890 --> 00:07:32.290
collaboration and shared technology further
183
00:07:32.290 --> 00:07:34.370
accelerates the pace of innovation in the
184
00:07:34.370 --> 00:07:37.330
space industry. It's a truly exciting era
185
00:07:37.330 --> 00:07:39.650
where the dream of widespread space access
186
00:07:40.130 --> 00:07:42.450
is slowly but surely becoming a tangible
187
00:07:42.450 --> 00:07:45.190
reality. Driven by these relentless efforts
188
00:07:45.190 --> 00:07:47.230
and engineering and iterative testing.
189
00:07:47.790 --> 00:07:49.910
Anna: Absolutely, Avery. The commercial space
190
00:07:49.910 --> 00:07:51.830
sector, spearheaded by companies like Blue
191
00:07:51.830 --> 00:07:53.950
Origin, isn't just about sending rockets
192
00:07:53.950 --> 00:07:56.310
skyward. It's about democratizing access to
193
00:07:56.310 --> 00:07:59.070
space and fostering a new era of innovation.
194
00:07:59.550 --> 00:08:01.910
Think about the ripple effect. As launch
195
00:08:01.910 --> 00:08:04.750
costs decrease and capabilities expand, more
196
00:08:04.750 --> 00:08:06.990
research can be conducted in microgravity,
197
00:08:07.150 --> 00:08:09.700
new industries can emerge, and eventually
198
00:08:09.940 --> 00:08:11.860
more people will have the opportunity to
199
00:08:11.860 --> 00:08:14.780
experience space firsthand. This isn't just a
200
00:08:14.780 --> 00:08:17.380
distant dream. It's a tangible future being
201
00:08:17.380 --> 00:08:19.940
built with each successful mission. The
202
00:08:19.940 --> 00:08:22.140
pursuit of sustainable space infrastructure,
203
00:08:22.140 --> 00:08:25.059
from orbital hotels to lunar bases, relies
204
00:08:25.059 --> 00:08:27.220
heavily on the foundational work being done
205
00:08:27.220 --> 00:08:30.020
now. Blue Origin's vision Grata
206
00:08:30.020 --> 00:08:32.820
team ferocity, step by step, ferociously,
207
00:08:32.820 --> 00:08:35.060
perfectly encapsulates this methodical yet
208
00:08:35.060 --> 00:08:37.210
ambitious approach. They are not only
209
00:08:37.210 --> 00:08:39.730
building rockets, but also developing the
210
00:08:39.730 --> 00:08:41.690
underlying technologies that will make
211
00:08:41.690 --> 00:08:44.010
sustained human presence in space a reality.
212
00:08:44.250 --> 00:08:46.730
This includes advanced engines, reusable
213
00:08:46.730 --> 00:08:49.410
launch systems, and even conceptual designs
214
00:08:49.410 --> 00:08:50.370
for space habitats.
215
00:08:50.370 --> 00:08:52.690
It's a long term game, but one with profound
216
00:08:52.690 --> 00:08:55.290
implications for our species. As we look
217
00:08:55.290 --> 00:08:57.210
outwards, the very act of exploring and
218
00:08:57.210 --> 00:08:59.130
expanding our reach into the cosmos
219
00:08:59.530 --> 00:09:01.450
Inevitably leads us to ponder our own
220
00:09:01.450 --> 00:09:04.220
existence, our origins, and our ultimate
221
00:09:04.220 --> 00:09:06.820
destiny. It's a journey that forces us to
222
00:09:06.820 --> 00:09:08.980
confront Some of the most profound mind
223
00:09:08.980 --> 00:09:10.900
bending theories about humanity's place in
224
00:09:10.900 --> 00:09:13.780
the universe. From the vastness of the
225
00:09:13.780 --> 00:09:16.140
cosmos to the intricate dance of fundamental
226
00:09:16.140 --> 00:09:18.940
particles, the universe seems to whisper
227
00:09:18.940 --> 00:09:21.620
questions about our significance, our
228
00:09:21.620 --> 00:09:23.900
uniqueness, and whether we are truly alone.
229
00:09:24.700 --> 00:09:27.100
These are not merely philosophical musings,
230
00:09:27.340 --> 00:09:29.980
but deeply scientific inquiries that drive
231
00:09:29.980 --> 00:09:32.580
much of our astrophysical research. The
232
00:09:32.580 --> 00:09:34.820
search for extraterrestrial life, the study
233
00:09:34.820 --> 00:09:37.340
of exoplanets, and the exploration of dark
234
00:09:37.340 --> 00:09:40.100
matter and dark energy all contribute to our
235
00:09:40.100 --> 00:09:42.180
evolving understanding of, uh, where we fit
236
00:09:42.180 --> 00:09:45.100
in the grand cosmic tapestry. It's a
237
00:09:45.100 --> 00:09:47.460
humbling, yet exhilarating realization that
238
00:09:47.460 --> 00:09:49.340
our journey into space Is intrinsically
239
00:09:49.340 --> 00:09:52.340
linked to our quest for self knowledge. Each
240
00:09:52.340 --> 00:09:55.180
discovery, whether it's a new exoplanet Or a
241
00:09:55.180 --> 00:09:57.020
deeper insight into the early universe,
242
00:09:57.420 --> 00:09:59.780
Reframes our perspective and challenges our
243
00:09:59.780 --> 00:10:02.140
anthropocentric views, Pushing us to imagine
244
00:10:02.140 --> 00:10:04.050
possibilities Far beyond our terrestrial
245
00:10:04.280 --> 00:10:04.840
confines.
246
00:10:05.720 --> 00:10:08.200
Shifting gears from philosophical quests,
247
00:10:08.520 --> 00:10:10.360
let's talk about some fascinating new
248
00:10:10.360 --> 00:10:12.920
findings from Mars. European Space
249
00:10:12.920 --> 00:10:15.320
Agency orbiters, Mars Express and
250
00:10:15.320 --> 00:10:18.160
ExoMars Trace Gas Orbiter have been busy
251
00:10:18.160 --> 00:10:20.040
Mapping dust devils on the red planet.
252
00:10:20.360 --> 00:10:23.000
Avery: That's right, anna. Uh, over two decades,
253
00:10:23.000 --> 00:10:24.920
researchers tracked an astounding
254
00:10:24.920 --> 00:10:27.920
1,039 dust devils. And what
255
00:10:27.920 --> 00:10:30.470
they found is pretty remarkable. These
256
00:10:30.470 --> 00:10:33.110
Martian whirlwinds Can actually reach speeds
257
00:10:33.110 --> 00:10:35.470
up to 98 miles per hour, or
258
00:10:35.470 --> 00:10:38.430
158 kilometers per hour, which is
259
00:10:38.430 --> 00:10:40.270
much faster than we previously thought.
260
00:10:40.830 --> 00:10:42.790
Anna: And this isn't just a cool fact. These
261
00:10:42.790 --> 00:10:44.990
findings are incredibly important for future
262
00:10:44.990 --> 00:10:47.590
Mars missions. Understanding how these dust
263
00:10:47.590 --> 00:10:49.710
devils behave Helps us plan better,
264
00:10:50.270 --> 00:10:52.230
Especially when it comes to the impact of
265
00:10:52.230 --> 00:10:54.910
dust on rover solar panels and the selection
266
00:10:54.910 --> 00:10:56.130
of safe landing sites.
267
00:10:56.680 --> 00:10:59.680
Avery: It's also a testament to innovative tech. As
268
00:10:59.680 --> 00:11:01.960
artificial intelligence played a key role,
269
00:11:02.520 --> 00:11:05.040
AI was used to analyze how these dust
270
00:11:05.040 --> 00:11:08.040
devils Shifted between frames, Essentially
271
00:11:08.040 --> 00:11:10.000
turning what might have been dismissed as
272
00:11:10.000 --> 00:11:12.920
image noise into valuable scientific
273
00:11:12.920 --> 00:11:15.080
measurements of wind speed and direction.
274
00:11:15.240 --> 00:11:17.120
Anna: The data also revealed some interesting
275
00:11:17.120 --> 00:11:20.040
patterns. Martian dust devils are most
276
00:11:20.040 --> 00:11:22.000
frequent during the daytime in spring and
277
00:11:22.000 --> 00:11:24.550
summer, Typically peaking between late
278
00:11:24.550 --> 00:11:27.110
morning and early afternoon. And they usually
279
00:11:27.110 --> 00:11:28.310
last only a few minutes.
280
00:11:28.790 --> 00:11:31.230
Avery: What's particularly significant, though, is
281
00:11:31.230 --> 00:11:33.750
how Martian dust behaves Compared to Earth.
282
00:11:34.070 --> 00:11:37.030
Here, dust settles relatively quickly, but
283
00:11:37.030 --> 00:11:39.430
on Mars, dust can linger for months.
284
00:11:39.990 --> 00:11:42.470
This makes understanding its uplift mechanism
285
00:11:42.470 --> 00:11:44.790
critical for predicting the planet's weather
286
00:11:44.790 --> 00:11:46.710
and even its long term climate.
287
00:11:47.110 --> 00:11:50.070
Anna: Exactly. This new global data is invaluable.
288
00:11:50.350 --> 00:11:52.470
It's helping scientists refine atmospheric
289
00:11:52.470 --> 00:11:54.470
models and significantly improve future
290
00:11:54.470 --> 00:11:57.150
weather forecasts for Mars, which is crucial
291
00:11:57.150 --> 00:11:58.950
as we look towards more sustained human
292
00:11:58.950 --> 00:11:59.710
presence there.
293
00:11:59.870 --> 00:12:02.150
Avery: And it's this profound connection, Anna,
294
00:12:02.150 --> 00:12:04.790
between our exploration of the cosmos and our
295
00:12:04.790 --> 00:12:07.070
internal philosophical quests that makes
296
00:12:07.070 --> 00:12:09.950
astronomy so endlessly captivating. Every
297
00:12:09.950 --> 00:12:12.710
new mission, every telescope image, every
298
00:12:12.710 --> 00:12:15.150
theoretical breakthrough serves not just to
299
00:12:15.150 --> 00:12:17.710
fill our scientific journals, but to enrich
300
00:12:17.710 --> 00:12:20.130
our human experience. It makes us question,
301
00:12:20.530 --> 00:12:23.410
imagine, and ultimately understand ourselves
302
00:12:23.410 --> 00:12:25.930
better in the grand scheme of things. From
303
00:12:25.930 --> 00:12:28.170
the subatomic to the supercluster, the
304
00:12:28.170 --> 00:12:31.090
universe is a symphony of mysteries. And we,
305
00:12:31.170 --> 00:12:33.570
as curious observers, are both part of the
306
00:12:33.570 --> 00:12:36.530
music and its eager listeners. As we continue
307
00:12:36.530 --> 00:12:38.770
to delve into the vastness, we're not just
308
00:12:38.770 --> 00:12:40.970
finding answers about distant stars and
309
00:12:40.970 --> 00:12:43.930
galaxies, but also discovering more about the
310
00:12:43.930 --> 00:12:46.560
intricate, evolving story of life itself and.
311
00:12:46.710 --> 00:12:48.870
And its potential, both here on Earth and
312
00:12:48.870 --> 00:12:51.590
perhaps far beyond. This ongoing
313
00:12:51.590 --> 00:12:54.110
dialogue between the known and the unknown is
314
00:12:54.110 --> 00:12:56.670
the very essence of discovery, constantly
315
00:12:56.670 --> 00:12:58.990
inviting us to expand our perceptions of
316
00:12:58.990 --> 00:12:59.750
what's possible.
317
00:13:00.790 --> 00:13:02.869
Anna: And that's it for today. Thank you for coming
318
00:13:02.869 --> 00:13:05.310
along with us on our cosmic journey. Join us
319
00:13:05.310 --> 00:13:07.070
again tomorrow for more insights into our
320
00:13:07.070 --> 00:13:09.270
incredible universe on Astronomy Daily.
321
00:13:09.830 --> 00:13:11.430
Until then, keep looking up.
322
00:13:14.460 --> 00:13:15.740
323
00:13:20.230 --> 00:13:20.250
Avery: Mhm.
324
00:13:22.460 --> 00:13:23.100
325
00:13:30.940 --> 00:13:31.580
we told.
326
00:13:34.740 --> 00:13:34.900
Avery: You.
