1
00:00:00.160 --> 00:00:03.919
Hello, and welcome to Astronomy Daily. I'm your host, Anna,
2
00:00:04.040 --> 00:00:06.639
and we have a big lineup of space discoveries and
3
00:00:06.719 --> 00:00:10.359
breakthroughs to share with you. Today, we'll journey beyond Neptune,
4
00:00:10.599 --> 00:00:13.919
where the James Web Space Telescope has made remarkable findings
5
00:00:13.919 --> 00:00:18.079
about mysterious objects in our Solar System's outer reaches. We'll
6
00:00:18.079 --> 00:00:21.079
hear from astronauts aboard the International Space Station who want
7
00:00:21.079 --> 00:00:24.280
to set the record straight about their extended mission. We'll
8
00:00:24.320 --> 00:00:27.559
also explore a fascinating new theory that challenges everything we
9
00:00:27.640 --> 00:00:30.120
thought we knew about the emergence of intelligent life in
10
00:00:30.160 --> 00:00:35.359
the universe. Plus, we'll examine groundbreaking analysis from asteroid venue samples,
11
00:00:35.719 --> 00:00:39.119
peek into Earth's surprisingly dynamic inner core, and look at
12
00:00:39.119 --> 00:00:43.600
innovative new technology for exploring low gravity environments. Strap in
13
00:00:43.679 --> 00:00:46.159
for an exciting journey through the latest developments in space
14
00:00:46.200 --> 00:00:50.960
science and exploration. Let's get started. NASA's James Web Space
15
00:00:51.000 --> 00:00:55.320
Telescope has revolutionized our understanding of trans Neptunian objects, those
16
00:00:55.359 --> 00:01:00.679
mysterious celestial bodies orbiting beyond Neptune's path. In an unprecedented study,
17
00:01:01.000 --> 00:01:03.719
Web has provided the first detailed look at the composition
18
00:01:03.799 --> 00:01:07.560
of these distant objects, revealing surprising new insights about our
19
00:01:07.560 --> 00:01:13.280
solar system's formation. Trans Neptunian objects, or TNOs, include everything
20
00:01:13.280 --> 00:01:16.879
from dwarf planets like Pluto and Eris to smaller bodies
21
00:01:16.920 --> 00:01:19.959
like Aracoth. While scientists have known about these objects since
22
00:01:20.000 --> 00:01:23.319
Pluto's discovery in nineteen thirty, we've never been able to
23
00:01:23.359 --> 00:01:27.280
study their composition in such detail until now. Using Web's
24
00:01:27.280 --> 00:01:31.560
Near infrared spectrograph, scientists have analyzed over seventy five TNOs
25
00:01:31.599 --> 00:01:34.359
in the first two years of the telescope's operation. What
26
00:01:34.439 --> 00:01:38.840
they found was completely unexpected. These objects can be categorized
27
00:01:38.879 --> 00:01:43.280
into three distinct spectral classes based on their surface composition.
28
00:01:44.000 --> 00:01:48.760
The first group, dubbed bowl type, shows strong signatures of water, ice,
29
00:01:48.840 --> 00:01:52.920
and some carbon dioxide, along with silicate rich dust. The
30
00:01:52.959 --> 00:01:58.239
second classification, called double dip, reveals complex organic molecules mixed
31
00:01:58.239 --> 00:02:01.840
with carbon dioxide and carbon monocchilide ices. The third group,
32
00:02:02.079 --> 00:02:05.719
known as cliff type, contains the most complex organic materials
33
00:02:05.719 --> 00:02:10.280
of all, along with compounds like methanol. This classification system
34
00:02:10.560 --> 00:02:14.840
isn't just about categorizing space rocks. It's helping scientists piece
35
00:02:14.879 --> 00:02:18.680
together the story of our solar system's early days. The
36
00:02:18.680 --> 00:02:22.159
theory is that these different compositions reflect where these objects
37
00:02:22.159 --> 00:02:25.719
originally formed, with bold types developing closer to the Sun
38
00:02:26.039 --> 00:02:30.280
where temperatures were higher, while double dips and cliffs formed
39
00:02:30.319 --> 00:02:34.280
in the colder outer regions. Particularly intriguing is that all
40
00:02:34.360 --> 00:02:38.120
objects found in undisturbed cold classical orbits belong to the
41
00:02:38.159 --> 00:02:42.680
cliff category. This suggests these objects have remained largely unchanged
42
00:02:42.759 --> 00:02:46.800
since the Solar System's formation, making them invaluable time capsules
43
00:02:46.800 --> 00:02:51.360
of our cosmic history. Web continues to study these fascinating objects,
44
00:02:51.400 --> 00:02:54.919
with new observations planned to examine extreme t andos that
45
00:02:55.039 --> 00:02:59.479
venture far into interstellar space. These ongoing studies promise to
46
00:02:59.520 --> 00:03:02.639
reveal e more about the materials and conditions that shaped
47
00:03:02.639 --> 00:03:07.240
our Solar System billions of years ago. Next up, let's
48
00:03:07.240 --> 00:03:09.520
pay a visit to the International Space Station for an
49
00:03:09.560 --> 00:03:13.759
update from our two favorite astronauts. In recent months, there's
50
00:03:13.800 --> 00:03:16.560
been quite a bit of attention on NASA astronauts Sunny
51
00:03:16.560 --> 00:03:20.400
Williams and Butch Wilmore, who found themselves on an unexpectedly
52
00:03:20.439 --> 00:03:24.360
extended stay aboard the International Space Station. While some media
53
00:03:24.400 --> 00:03:27.199
outlets have painted this as a story of stranded astronauts,
54
00:03:27.520 --> 00:03:30.759
the reality is quite different from these dramatic headlines. The
55
00:03:30.879 --> 00:03:34.240
duo originally launched on Boeing Starliner spacecraft for what was
56
00:03:34.280 --> 00:03:38.560
planned as a ten day mission. However, when Starliner experienced
57
00:03:38.599 --> 00:03:42.280
thruster issues during docking maneuvers, NASA made the decision to
58
00:03:42.319 --> 00:03:46.680
adjust their plans. Rather than rushing a solution, they've incorporated
59
00:03:46.719 --> 00:03:50.719
Williams and Wilmore into the ongoing crew rotation schedule, specifically
60
00:03:50.800 --> 00:03:54.319
as part of SpaceX's Crew nine mission. Both astronauts have
61
00:03:54.319 --> 00:03:56.639
been quick to set the record straight about their situation.
62
00:03:57.240 --> 00:04:01.199
As Wilmore recently explained to CNN's Anderson Cooper, we don't
63
00:04:01.199 --> 00:04:04.759
feel abandoned, we don't feel stuck, we don't feel stranded.
64
00:04:05.520 --> 00:04:08.800
In fact, he emphasized that mission extensions are simply part
65
00:04:08.800 --> 00:04:11.800
of the job in human spaceflight, where being prepared for
66
00:04:11.879 --> 00:04:16.800
contingencies is fundamental to their training. What's particularly noteworthy is
67
00:04:16.839 --> 00:04:20.399
that both astronauts have maintained their regular duties throughout this
68
00:04:20.560 --> 00:04:24.439
extended stay. Williams has even managed to break the record
69
00:04:24.560 --> 00:04:27.879
for most cumulative space walking time by a woman during
70
00:04:27.879 --> 00:04:31.920
this period. They've been fully integrated into the station's operations
71
00:04:31.920 --> 00:04:35.879
with access to all necessary supplies and equipment. The situation
72
00:04:36.000 --> 00:04:39.120
gained additional attention when it became part of a political discussion,
73
00:04:39.879 --> 00:04:43.160
but the astronauts have remained focused on their mission. They're
74
00:04:43.199 --> 00:04:45.959
now scheduled to return to Earth in March following the
75
00:04:46.079 --> 00:04:50.240
arrival of Crew ten. As Wilmore puts it, they're not stranded.
76
00:04:50.759 --> 00:04:54.279
They're prepared and committed, which is exactly what you'd expect
77
00:04:54.279 --> 00:04:58.160
from seasoned space professionals. Both Williams and Wilmore, veterans of
78
00:04:58.240 --> 00:05:02.600
previous long duration space mission, have expressed their continued enjoyment
79
00:05:02.639 --> 00:05:06.199
of life in orbit. As Williams noted, it's just amazing
80
00:05:06.319 --> 00:05:09.959
how quickly you readapt to life in space. She even
81
00:05:10.000 --> 00:05:13.199
admitted that when the time comes to return home, they'll
82
00:05:13.240 --> 00:05:15.600
likely feel a touch of sadness at leaving their weightless
83
00:05:15.639 --> 00:05:19.000
environment behind. And just a little side note, how famous
84
00:05:19.040 --> 00:05:22.680
has that hair become? All right, let's get back on track.
85
00:05:23.120 --> 00:05:25.800
New research from Penn State is challenging our long held
86
00:05:25.800 --> 00:05:29.040
assumptions about the likelihood of intelligent life in the universe.
87
00:05:29.560 --> 00:05:33.800
For decades, scientists believe that humanity's emergence was an incredibly
88
00:05:33.879 --> 00:05:38.480
rare cosmic accident, But this fresh perspective suggests something quite different.
89
00:05:39.040 --> 00:05:42.839
The traditional view, known as the hard steps theory, argued
90
00:05:42.879 --> 00:05:46.519
that the evolution of intelligent life required an unlikely series
91
00:05:46.560 --> 00:05:51.079
of fortunate events. However, this new study proposes that intelligence
92
00:05:51.160 --> 00:05:54.720
might be more of an inevitable outcome of planetary evolution,
93
00:05:55.279 --> 00:05:59.240
both on Earth and potentially on other worlds. The researchers
94
00:05:59.279 --> 00:06:04.040
explain that earth environment wasn't always hospitable to complex life forms. Instead,
95
00:06:04.160 --> 00:06:08.079
it evolved through distinct phases, creating what they call windows
96
00:06:08.079 --> 00:06:12.000
of habitability. For instance, the development of complex animal life
97
00:06:12.040 --> 00:06:15.959
required specific oxygen levels in the atmosphere. This didn't happen
98
00:06:15.959 --> 00:06:20.079
by chance, it was a natural consequence of photosynthesizing microbes
99
00:06:20.160 --> 00:06:25.079
gradually changing Earth's atmosphere over time. What's particularly intriguing is
100
00:06:25.120 --> 00:06:28.879
their suggestion that humans didn't evolve early or late in
101
00:06:28.920 --> 00:06:33.120
Earth's history, but right on time when conditions were finally suitable.
102
00:06:33.560 --> 00:06:36.439
As Dan Mills, one of the study's authors, explains, it
103
00:06:36.480 --> 00:06:38.879
may simply be a matter of time before other planets
104
00:06:38.879 --> 00:06:43.279
achieved similar conditions, with some potentially reaching these milestones faster
105
00:06:43.480 --> 00:06:47.680
or slower than Earth did. The team, combining expertise from
106
00:06:47.680 --> 00:06:51.959
both astrophysics and geobiology argues that we should view evolution
107
00:06:52.120 --> 00:06:56.000
through the lens of geological time scales, rather than comparing
108
00:06:56.079 --> 00:07:00.160
it to the Sun's lifespan. This shift in perspective suggests
109
00:07:00.319 --> 00:07:02.879
that the development of intelligence might be more of a
110
00:07:02.920 --> 00:07:08.800
predictable process, unfolding as global conditions allow. This research opens
111
00:07:08.839 --> 00:07:12.199
up exciting possibilities about the prevalence of intelligent life in
112
00:07:12.240 --> 00:07:16.879
the universe. If intelligence emerges naturally when planetary conditions are right,
113
00:07:17.480 --> 00:07:21.199
rather than through an improbable series of accidents, we might
114
00:07:21.240 --> 00:07:24.639
not be as alone in the cosmos as we once thought.
115
00:07:25.079 --> 00:07:27.680
Next an update from the mission that just keeps on giving.
116
00:07:28.519 --> 00:07:33.120
In a remarkable scientific achievement, NASA's Osyrius Rex mission has
117
00:07:33.160 --> 00:07:37.040
revealed groundbreaking discoveries from its sample collection of asteroid Benu.
118
00:07:37.959 --> 00:07:41.560
The mission, which successfully returned approximately one hundred and twenty
119
00:07:41.560 --> 00:07:45.000
grams of pristine asteroid material to Earth last September, is
120
00:07:45.040 --> 00:07:49.759
providing unprecedented insights into the early Solar System. Analysis of
121
00:07:49.759 --> 00:07:53.319
the samples has yielded an extraordinary finding, the presence of
122
00:07:53.360 --> 00:07:57.279
tiny crystals of salt minerals, specifically halite and sylvite. This
123
00:07:57.319 --> 00:08:00.759
discovery is particularly significant because halleite is ecx extremely rare
124
00:08:00.800 --> 00:08:03.720
in meteorites, having been found in only three out of
125
00:08:03.800 --> 00:08:07.439
hundreds of thousands of known specimens on Earth. The presence
126
00:08:07.439 --> 00:08:10.480
of these salt minerals suggests that water activity may have
127
00:08:10.519 --> 00:08:14.120
once existed on benus parent body. The research team has
128
00:08:14.160 --> 00:08:20.160
also identified various other salt minerals, including sodium carbonates, phosphates, sulfates,
129
00:08:20.319 --> 00:08:24.639
and fluorides. These minerals typically form through the evaporation of brines,
130
00:08:25.000 --> 00:08:27.720
similar to the deposits we see in Earth's salt lakes.
131
00:08:28.399 --> 00:08:31.920
This discovery provides compelling evidence of ancient water activity in
132
00:08:31.959 --> 00:08:35.360
the earliest days of our solar system, But perhaps even
133
00:08:35.440 --> 00:08:38.000
more intriguing is what these salt minerals mean for the
134
00:08:38.039 --> 00:08:42.720
potential development of life's building blocks on Earth. These minerals
135
00:08:42.759 --> 00:08:46.799
act as catalysts for forming organic compounds such as nucleobases
136
00:08:46.840 --> 00:08:52.039
and nucleosides, the fundamental components of biological systems. Indeed, further
137
00:08:52.120 --> 00:08:55.159
analysis of the Benuz samples revealed a diverse array of
138
00:08:55.240 --> 00:08:59.639
organic compounds, including fourteen of the twenty amino acids found
139
00:08:59.679 --> 00:09:03.720
in earth biological processes, as well as all five nucleobases
140
00:09:03.759 --> 00:09:07.320
present in RNA and DNA. While this doesn't indicate the
141
00:09:07.360 --> 00:09:10.440
presence of life on Benu, it does suggest that the
142
00:09:10.519 --> 00:09:14.679
asteroid's parent body once provided an environment conducive to assembling
143
00:09:14.759 --> 00:09:19.200
life's essential components. These findings could have significant implications for
144
00:09:19.240 --> 00:09:22.360
our understanding of similar environments elsewhere in the Solar System,
145
00:09:22.879 --> 00:09:26.559
particularly on bodies like Saturn's moon, Enceladus and the dwarf
146
00:09:26.639 --> 00:09:29.639
planet series, both of which are known to have subsurface
147
00:09:29.639 --> 00:09:34.159
brine oceans. This pristine sample from Benu continues to offer
148
00:09:34.240 --> 00:09:38.679
new insights as researchers delve deeper into its analysis, potentially
149
00:09:38.759 --> 00:09:42.279
reshaping our understanding of the early Solar System and the
150
00:09:42.279 --> 00:09:46.960
distribution of life's building blocks throughout space. Let's turn our
151
00:09:46.960 --> 00:09:49.919
attention to some fascinating new findings about Earth's inner core
152
00:09:50.000 --> 00:09:53.519
that are challenging our previous understanding of our planet's deepest layer.
153
00:09:54.320 --> 00:09:57.759
Recent research has revealed that the inner core, long thought
154
00:09:57.759 --> 00:10:00.440
to be a solid sphere of iron and nickel, is
155
00:10:00.480 --> 00:10:04.399
actually far less rigid than scientists previously believed. Deep beneath
156
00:10:04.399 --> 00:10:08.120
our feet nearly three thousand miles below the surface, scientists
157
00:10:08.200 --> 00:10:12.360
have detected unexpected structural changes in the inner cores near surface.
158
00:10:13.120 --> 00:10:17.120
This discovery comes from analyzing seismic waves from one hundred
159
00:10:17.120 --> 00:10:20.919
and twenty one repeating earthquakes near the South Sandwich Islands
160
00:10:21.320 --> 00:10:24.720
over a period spanning from nineteen ninety one to twenty
161
00:10:24.759 --> 00:10:29.039
twenty four. What makes this particularly interesting is how it
162
00:10:29.080 --> 00:10:32.720
appears to interact with the outer core, that swirling layer
163
00:10:32.759 --> 00:10:36.200
of liquid metal that surrounds it. The turbulent motion of
164
00:10:36.240 --> 00:10:39.679
the outer core seems to be capable of actually deforming
165
00:10:39.720 --> 00:10:42.960
the inner core, something we hadn't observed happening on human
166
00:10:43.000 --> 00:10:47.120
time scales before. These findings have significant implications for our
167
00:10:47.200 --> 00:10:51.039
understanding of Earth's magnetic field, which acts as our planet's
168
00:10:51.039 --> 00:10:56.039
protective shield against harmful solar radiation. The interaction between the
169
00:10:56.039 --> 00:10:59.120
inner and outer core plays a crucial role in generating
170
00:10:59.159 --> 00:11:02.600
and maintaining this magnetic field. If the inner core is
171
00:11:02.639 --> 00:11:05.960
more malleable than we thought, it could help explain observed
172
00:11:06.039 --> 00:11:09.799
variations in the field's strength and stability over time. The
173
00:11:09.879 --> 00:11:14.240
research also supports previous observations suggesting that the inner core's
174
00:11:14.360 --> 00:11:18.840
rotation isn't constant. Some models indicate it may have slowed
175
00:11:18.960 --> 00:11:22.399
or even reverse direction around twenty ten, which aligns with
176
00:11:22.440 --> 00:11:27.080
observed changes in seismic wave patterns. This could potentially influence
177
00:11:27.120 --> 00:11:29.639
subtle changes in Earth's rotation and even the length of
178
00:11:29.639 --> 00:11:33.360
our days. This new understanding of our planet's core is
179
00:11:33.440 --> 00:11:37.240
forcing us to reconsider how Earth's internal engine works and
180
00:11:37.360 --> 00:11:41.000
opens up exciting new questions about the dynamic processes occurring
181
00:11:41.039 --> 00:11:45.240
deep within our planet. In our final science story today,
182
00:11:45.600 --> 00:11:48.399
we're looking at an innovative new approach to exploring low
183
00:11:48.399 --> 00:11:53.279
gravity environments like asteroids and other celestial bodies. Researchers at
184
00:11:53.360 --> 00:11:57.480
UCLA's Robotics and Mechanisms Laboratory have developed a fascinating new
185
00:11:57.559 --> 00:12:01.759
robot system called splitter. It's the space and planetary limbed
186
00:12:01.759 --> 00:12:06.320
Intelligent Tether Technology exploration robot. What makes Splitter unique is
187
00:12:06.360 --> 00:12:10.279
its design. Imagine two small, four legged robots connected by
188
00:12:10.279 --> 00:12:13.840
a tether working together like a high tech version of
189
00:12:13.879 --> 00:12:17.679
the game Bola. But don't let this simple description fool you.
190
00:12:18.320 --> 00:12:22.279
The system employs sophisticated control mechanisms that allow it to
191
00:12:22.320 --> 00:12:27.159
move with remarkable stability, even in airless environments. The team
192
00:12:27.240 --> 00:12:31.200
chose a jumping locomotion method rather than traditional wheeled rovers
193
00:12:31.559 --> 00:12:34.799
because it's much more effective for navigating the jagged, uneven
194
00:12:34.879 --> 00:12:39.200
terrain found on asteroids, and unlike flying robots, it doesn't
195
00:12:39.240 --> 00:12:42.559
need an atmosphere to operate. Each robot weighs just about
196
00:12:42.600 --> 00:12:45.320
ten kilograms on Earth, making them even more agile in
197
00:12:45.360 --> 00:12:49.679
low gravity environments. What's particularly clever about Splitter is how
198
00:12:49.679 --> 00:12:53.519
it maintains control during movement. The system uses something called
199
00:12:53.559 --> 00:12:57.480
inertial morphing, where the robots adjust their leg configurations and
200
00:12:57.559 --> 00:13:00.879
tether length to stabilize their motion. This is managed through
201
00:13:00.879 --> 00:13:04.919
a sophisticated predictive control system that can calculate exactly how
202
00:13:04.960 --> 00:13:09.679
to position each component for optimal stability. The robots can
203
00:13:09.720 --> 00:13:13.159
even work together for tasks like exploring cave systems, with
204
00:13:13.240 --> 00:13:17.120
one robot anchoring itself while the other repels down using
205
00:13:17.159 --> 00:13:21.320
their connecting tether. While Splitter currently exists mainly as a
206
00:13:21.320 --> 00:13:25.000
computer model, it represents an exciting new direction in space
207
00:13:25.039 --> 00:13:28.600
exploration technology that could one day help us investigate some
208
00:13:28.679 --> 00:13:33.399
of the most challenging environments in our Solar system. While
209
00:13:33.440 --> 00:13:36.279
that brings us to the end of another fascinating episode
