00:00:00.240 --> 00:00:03.120
Welcome to Astronomy Daily, where we bring you the latest
2
00:00:03.120 --> 00:00:06.639
in space and astronomy news. I'm your host, Anna, and
3
00:00:06.719 --> 00:00:09.640
today we'll explore an exciting array of cosmic events, from
4
00:00:09.679 --> 00:00:13.000
Blue Origins historic all female flight to supernovae that may
5
00:00:13.000 --> 00:00:16.600
have shaped Earth's history, and much more. From stellar rhythms
6
00:00:16.600 --> 00:00:19.559
that reveal the secrets of our galaxy to NASA's Lucy
7
00:00:19.600 --> 00:00:23.399
spacecraft preparing for its next asteroid encounter. We have a
8
00:00:23.519 --> 00:00:26.679
universe of discoveries to share with you today. Let's kick
9
00:00:26.719 --> 00:00:28.960
things off today with the one story everyone seems to
10
00:00:28.960 --> 00:00:33.000
be talking about. Blue Origin made history this past Monday
11
00:00:33.119 --> 00:00:37.000
with a groundbreaking achievement in human spaceflight, the first all
12
00:00:37.039 --> 00:00:41.439
female crewed rocket launch since nineteen sixty three. What took
13
00:00:41.439 --> 00:00:45.320
them so long? Their new Shepherd rocket carried six remarkable
14
00:00:45.320 --> 00:00:48.479
women beyond Earth's atmosphere on the company's thirty first launch
15
00:00:48.479 --> 00:00:52.560
and eleventh crude mission overall. At nine thirty am Eastern
16
00:00:52.600 --> 00:00:56.359
on April fourteenth, the RSS Carmen Line space capsule lifted
17
00:00:56.359 --> 00:00:59.119
off from Blue Origins Launch Site one in West Texas
18
00:00:59.399 --> 00:01:03.679
with an extra ordinary passenger manifest Pop superstar Katy Perry
19
00:01:03.759 --> 00:01:09.079
joined mission leader Lauren Sanchez journalist Gail King, bioastronautics scientist
20
00:01:09.159 --> 00:01:13.000
Amanda and Guien, film producer carry Anne Flynn, and former
21
00:01:13.079 --> 00:01:16.799
NASA rocket scientist Ayisha Bo on this historic journey. The
22
00:01:16.840 --> 00:01:20.480
flight itself lasted approximately ten point five minutes, but its
23
00:01:20.480 --> 00:01:24.799
impact will be felt for generations. During those brief moments
24
00:01:24.799 --> 00:01:28.079
in space, the crew experienced about four minutes of weightlessness
25
00:01:28.359 --> 00:01:32.120
as their capsule arked above the Carmen Line, the internationally
26
00:01:32.159 --> 00:01:35.959
recognized boundary of space at sixty two miles altitude. Despite
27
00:01:35.959 --> 00:01:40.040
the brevity of their spaceflight, each woman returned transformed by
28
00:01:40.079 --> 00:01:44.040
what astronauts often call the overview effect, that profound shift
29
00:01:44.040 --> 00:01:46.599
and awareness that comes from seeing our planet from space.
30
00:01:47.239 --> 00:01:50.200
As Katy Perry eloquently put it after landing, it is
31
00:01:50.239 --> 00:01:54.000
the highest high and it is surrendered to the unknown trust.
32
00:01:55.000 --> 00:01:59.239
The mission carried special significance beyond its all female crew composition.
33
00:02:00.000 --> 00:02:02.879
Amanda and Guyen made history as the first Vietnamese and
34
00:02:02.920 --> 00:02:06.040
Southeast Asian woman to fly to space. For Gail King,
35
00:02:06.120 --> 00:02:09.199
who has an outspoken fear of flying, the mission represented
36
00:02:09.240 --> 00:02:13.319
an extraordinary step outside her comfort zone. Each passenger brought
37
00:02:13.319 --> 00:02:16.479
personal items that carried deep meaning. Perry brought a daisy,
38
00:02:16.520 --> 00:02:19.159
which she described as a resilient flower that grows through
39
00:02:19.199 --> 00:02:23.680
any condition, symbolizing strength and beauty. And Guyen carried two
40
00:02:23.719 --> 00:02:27.479
particularly poignant items, her hospital band from a sexual assault
41
00:02:27.680 --> 00:02:30.240
and a written promise to herself from that time, using
42
00:02:30.319 --> 00:02:34.120
the flight to honor her journey of healing. For Lauren Sanchez,
43
00:02:34.159 --> 00:02:38.280
the mission leader and fiance of Blue Origin founder Jeff Bezos,
44
00:02:38.319 --> 00:02:42.639
the experience revealed Earth's underlying unity. We are so connected,
45
00:02:42.919 --> 00:02:46.319
more connected than you realize, she reflected, noting how the
46
00:02:46.400 --> 00:02:50.280
view from space dissolves the artificial divisions between people. This
47
00:02:50.520 --> 00:02:54.680
historic suborbital flight not only broke barriers, but also demonstrated
48
00:02:54.719 --> 00:02:59.159
the expanding horizons of commercial spaceflight, where increasingly diverse crews
49
00:02:59.199 --> 00:03:02.560
are experiencing a life changing perspective that comes from seeing
50
00:03:02.639 --> 00:03:05.879
our fragile, blue planet against the vast darkness of space.
51
00:03:06.840 --> 00:03:09.319
Each of the women who experienced the historic n S
52
00:03:09.400 --> 00:03:13.120
thirty one mission returned to Earth with transformative insights that
53
00:03:13.199 --> 00:03:17.280
went far beyond the typical excitement of spaceflight. Their perspectives
54
00:03:17.360 --> 00:03:20.199
offer a glimpse into how seeing our planet from above
55
00:03:20.520 --> 00:03:25.479
can fundamentally shift human consciousness. Mission leader Lauren Sanchez described
56
00:03:25.520 --> 00:03:29.960
Earth from space as profoundly quiet and peaceful. We're so connected,
57
00:03:30.199 --> 00:03:33.680
more connected than you realize, she reflected, because you just
58
00:03:33.719 --> 00:03:36.360
see all these things that divide us but were not.
59
00:03:37.599 --> 00:03:40.120
The experience left her wanting to come back and just
60
00:03:40.240 --> 00:03:43.680
hug everyone with the realization that we're in this together.
61
00:03:44.680 --> 00:03:48.479
Sanchez expressed hope that more people could experience this perspective shift,
62
00:03:49.039 --> 00:03:52.520
uncertain of just how deeply it would change her. For
63
00:03:52.560 --> 00:03:56.400
Amanda ne Gullen, the flight carried immense symbolic weight as
64
00:03:56.400 --> 00:03:59.520
she became the first Vietnamese and Southeast Asian woman in space.
65
00:04:00.159 --> 00:04:03.960
Her journey held special significance for survivors of trauma. I
66
00:04:04.080 --> 00:04:06.439
just want all survivors to know that you can heal.
67
00:04:07.080 --> 00:04:10.280
No dream is too wild, she said, referencing her own
68
00:04:10.319 --> 00:04:14.120
experience as a sexual assault survivor. By bringing her hospital
69
00:04:14.159 --> 00:04:17.000
band from that day into space, she honored her past
70
00:04:17.000 --> 00:04:20.439
self and demonstrated the possibility of healing and achievement even
71
00:04:20.439 --> 00:04:24.120
after profound trauma. Gail King, who has a well known
72
00:04:24.160 --> 00:04:28.480
fear of flying, found unexpected courage through the experience. Eleanor
73
00:04:28.560 --> 00:04:31.920
Roosevelt once said, courage is doing something that scares you,
74
00:04:32.000 --> 00:04:35.079
but you do it anyway. King reflected, now that I've
75
00:04:35.079 --> 00:04:37.399
done it, I really do feel I can take on anything.
76
00:04:38.279 --> 00:04:40.959
She described the powerful silence of space and how it
77
00:04:41.000 --> 00:04:44.879
reminded her of our shared responsibility on Earth. It's really
78
00:04:44.959 --> 00:04:48.399
quiet and peaceful. If everybody could experience that piece that
79
00:04:48.480 --> 00:04:53.040
we had up there, I'll never ever, ever forget. Aisha bo,
80
00:04:53.199 --> 00:04:56.120
a former NASA rocket scientist, was transformed by the view.
81
00:04:57.160 --> 00:04:59.839
I will never be the same, she declared, noting how
82
00:05:00.079 --> 00:05:02.959
Earth filled their windows with no visible boundaries or borders.
83
00:05:03.519 --> 00:05:07.079
Her message after landing was emphatically clear, dream it planet
84
00:05:07.160 --> 00:05:09.279
and go and do it. I never really thought I
85
00:05:09.279 --> 00:05:11.240
could go to space, although I really wanted to go.
86
00:05:12.240 --> 00:05:14.879
For Katie Perry, the experience ranked as her life's second
87
00:05:14.920 --> 00:05:18.680
most incredible moment after the birth of her daughter. It's
88
00:05:18.680 --> 00:05:21.560
not about me, it's not about singing my songs. It's
89
00:05:21.600 --> 00:05:25.600
about a collective energy, Perry emphasized. It's about making space
90
00:05:25.639 --> 00:05:28.920
for future women and taking up space and belonging. The
91
00:05:29.000 --> 00:05:31.879
bond formed through this shared journey created what King called
92
00:05:31.920 --> 00:05:35.519
a true sisterhood that will connect these pioneering women forever.
93
00:05:37.079 --> 00:05:39.759
Speaking of launches, let's get a quick roundup of what
94
00:05:39.800 --> 00:05:42.920
else is planned this week. The global launch schedule is
95
00:05:42.959 --> 00:05:45.000
hitting a bit of a lull this week, with just
96
00:05:45.079 --> 00:05:48.759
four launches on the calendar, but each mission carries significant
97
00:05:48.800 --> 00:05:53.600
importance for space exploration and national security. Leading the week's
98
00:05:53.600 --> 00:05:56.959
activities is a MINOTAURNA four rocket set to lift off
99
00:05:57.000 --> 00:06:01.519
from Vandenberg Space for Space in California on Wednesday. This mission,
100
00:06:01.839 --> 00:06:05.879
designated NROLL one hundred seventy four, will carry a classified
101
00:06:05.879 --> 00:06:09.800
payload for the National Reconnaissance Office. The seventy eight foot
102
00:06:09.800 --> 00:06:13.399
tall four stage rocket, derived from the Peacekeeper missile design,
103
00:06:13.879 --> 00:06:18.000
will follow a southeasterly trajectory to place its mysterious cargo
104
00:06:18.199 --> 00:06:21.800
into low Earth orbit. This marks the first Minotaur for
105
00:06:22.000 --> 00:06:24.399
mission of twenty twenty five, and just the sixth in
106
00:06:24.439 --> 00:06:30.199
the vehicle's operational history. Friday brings US Firefly Aerospace's Alpha rocket,
107
00:06:30.519 --> 00:06:33.279
which will make another attempt to launch Lockheed Martin's new
108
00:06:33.480 --> 00:06:37.480
LM four hundred satellite bus from Vandenberg. Dubbed Message in
109
00:06:37.560 --> 00:06:41.160
a Booster, this mission has faced multiple delays since its
110
00:06:41.160 --> 00:06:44.800
originally scheduled March launch window. The LM four hundred will
111
00:06:44.800 --> 00:06:49.000
carry a demonstration communications payload into orbit, marking Alpha's first
112
00:06:49.000 --> 00:06:52.160
flight of twenty twenty five and its sixth mission overall.
113
00:06:53.000 --> 00:06:55.680
The two stage rocket stands nearly ninety seven feet tall
114
00:06:56.079 --> 00:06:58.920
and uses kerosene and liquid oxygen to power its reaver
115
00:06:59.040 --> 00:07:01.920
engines in the first day and single lightning engine in
116
00:07:01.959 --> 00:07:05.360
the second stage. SpaceX rounds out the week with two
117
00:07:05.360 --> 00:07:09.680
Falcon nine launches. The first, scheduled for Saturday from Vandenberg,
118
00:07:10.079 --> 00:07:13.399
will loft another classified NRO payload, believed to be the
119
00:07:13.439 --> 00:07:18.160
tenth batch of Starshield Reconnaissance satellites. The booster supporting this
120
00:07:18.279 --> 00:07:20.959
mission is expected to land on the drone ship of
121
00:07:21.000 --> 00:07:23.920
Course I Still Love You, stationed about four hundred miles
122
00:07:23.920 --> 00:07:27.720
downrange in the Pacific Ocean. The second Falcon nine mission
123
00:07:27.759 --> 00:07:31.560
comes Monday with the CRS thirty two cargo resupply mission
124
00:07:31.759 --> 00:07:35.680
to the International Space Station, launching from Kennedy Space Center
125
00:07:35.759 --> 00:07:40.720
in Florida. This flight will deliver essential supplies, scientific experiments,
126
00:07:41.000 --> 00:07:44.920
and spare parts to the orbiting laboratory. Among the science
127
00:07:44.920 --> 00:07:47.680
payloads is a French atomic clock for the Atomic Clock
128
00:07:47.800 --> 00:07:51.519
Ensemble in Space experiment, which will test Einstein's theory of
129
00:07:51.600 --> 00:07:55.040
general relativity by measuring how gravity affects the flow of
130
00:07:55.120 --> 00:07:59.920
time with unprecedented precision. Also heading to the ISS are
131
00:08:00.120 --> 00:08:03.879
experiments to monitor airborne particles inside the station, a robotic
132
00:08:03.920 --> 00:08:09.480
spacecraft guidance demonstration, pharmaceutical manufacturing experiments, and plant growth studies.
133
00:08:10.279 --> 00:08:13.120
The Falcon nine booster for this mission is expected to
134
00:08:13.160 --> 00:08:15.920
return for a landing at Cape Canaveral's landing Zone one
135
00:08:15.959 --> 00:08:21.600
shortly after launch. Meanwhile, further out in space, NASA's Lucy
136
00:08:21.639 --> 00:08:25.199
spacecraft is now just days away from its second asteroid encounter,
137
00:08:25.720 --> 00:08:28.759
approaching the small Main Belt asteroid Donal Johansson at a
138
00:08:28.800 --> 00:08:32.720
distance of less than fifty million miles. The April twentieth
139
00:08:32.759 --> 00:08:36.000
rendezvous will serve as a comprehensive dress rehearsal for Lucy's
140
00:08:36.000 --> 00:08:40.679
primary mission, exploring multiple Trojan asteroids that share Jupiter's orbit
141
00:08:40.759 --> 00:08:44.519
around the Sun over the next decade. The upcoming flyby
142
00:08:44.600 --> 00:08:48.559
builds on lessons learned from Lucy's first asteroid encounter last November,
143
00:08:48.879 --> 00:08:53.320
when it successfully visited the tiny Main Belt asteroid Dinkinesh
144
00:08:53.399 --> 00:08:57.399
and its satellite cellum mission controllers are now preparing for
145
00:08:57.440 --> 00:09:02.039
a more complex observation sequence as Lucy approaches Donald Johansson
146
00:09:03.000 --> 00:09:06.080
at its closest approach, scheduled for one fifty one pm
147
00:09:06.159 --> 00:09:09.639
Eastern on Saturday. Lucy will pass within just five hundred
148
00:09:09.639 --> 00:09:12.879
and ninety six miles of the asteroid. About thirty minutes
149
00:09:12.919 --> 00:09:16.159
before this moment. The spacecraft will orient itself to track
150
00:09:16.200 --> 00:09:19.919
Donald Johansson, temporarily turning its high gain antenna away from
151
00:09:19.960 --> 00:09:24.879
Earth and suspending communications. Guided by its terminal tracking system,
152
00:09:25.080 --> 00:09:28.159
Lucy will autonomously rotate to keep the asteroid in view
153
00:09:28.480 --> 00:09:32.759
while all three science instruments collect data. Unlike the Dinkinesh encounter,
154
00:09:33.080 --> 00:09:36.159
Lucy will need to stop tracking Donald Johansson forty seconds
155
00:09:36.240 --> 00:09:40.799
before closest approach to protect its sensitive instruments from intense sunlight.
156
00:09:41.320 --> 00:09:44.519
As in counterphase. Lead Michael Vincent explains, if you are
157
00:09:44.559 --> 00:09:47.840
sitting on the asteroid watching Lucy approach, you would have
158
00:09:47.879 --> 00:09:50.240
to shield your eyes from the sun while waiting for
159
00:09:50.320 --> 00:09:53.919
Lucy to emerge from the glare. After Lucy passes, the
160
00:09:53.960 --> 00:09:56.759
positions will be reversed, so we have to shield the
161
00:09:56.759 --> 00:10:00.960
instruments in the same way. This challenging gean is unique
162
00:10:00.960 --> 00:10:06.159
among Lucy's planned asteroid encounters. After closest approach, the spacecraft
163
00:10:06.159 --> 00:10:09.320
will reorient its solar arrays toward the Sun and re
164
00:10:09.480 --> 00:10:14.080
establish communication with Earth approximately an hour later. The twenty
165
00:10:14.080 --> 00:10:17.159
five minute round trip light delay presents its own challenges.
166
00:10:17.639 --> 00:10:21.480
When mission controllers command data playback after closest approach, they'll
167
00:10:21.519 --> 00:10:23.840
need to wait nearly half an hour before receiving any
168
00:10:23.840 --> 00:10:28.960
images or confirmation that their commands were received. Donald Johanson
169
00:10:29.000 --> 00:10:33.200
itself presents an intriguing target, representing a fragment from a
170
00:10:33.240 --> 00:10:35.559
collision that occurred one hundred and fifty million years ago,
171
00:10:36.039 --> 00:10:38.480
making it one of the youngest Main Belt asteroids ever
172
00:10:38.600 --> 00:10:42.799
visited by a spacecraft. As mission program scientist Tom Statler notes,
173
00:10:43.200 --> 00:10:45.879
every asteroid has a different story to tell, and these
174
00:10:45.919 --> 00:10:48.679
stories weave together to paint the history of our Solar System.
175
00:10:50.200 --> 00:10:53.519
Next up today, a fascinating new study suggests that deadly
176
00:10:53.600 --> 00:10:57.440
cosmic explosions may have twice brought mass extinction to our planet.
177
00:10:57.879 --> 00:11:00.720
Researchers from Keele University have linked TiO queue of Earth's
178
00:11:00.720 --> 00:11:04.919
major extinction events to nearby supernova explosions, stellar deaths so
179
00:11:05.080 --> 00:11:09.759
powerful they could have severely disrupted Earth's atmosphere. These massive
180
00:11:09.799 --> 00:11:13.519
stellar blasts, which occur when large stars collapse and explode
181
00:11:13.559 --> 00:11:16.120
at the end of their lives, may have destroyed our
182
00:11:16.159 --> 00:11:20.759
planet's protective ozone layer triggered acid rain and exposed Earth's
183
00:11:20.759 --> 00:11:23.879
surface to dangerous levels of ultraviolet radiation from the Sun.
184
00:11:24.919 --> 00:11:28.759
The researchers specifically point to the Ordovician extinction about four
185
00:11:28.879 --> 00:11:31.720
hundred forty five million years ago and the Late Devonian
186
00:11:31.759 --> 00:11:35.519
extinction around three hundred seventy two million years ago as
187
00:11:35.720 --> 00:11:41.360
likely candidates influenced by these cosmic catastrophes. The Ordovician event
188
00:11:41.440 --> 00:11:44.279
wiped out sixty percent of marine invertebrates at a time
189
00:11:44.360 --> 00:11:47.200
when life was largely confined to the seas, while the
190
00:11:47.240 --> 00:11:51.759
Late Devonian extinction eliminated approximately seventy percent of all species,
191
00:11:52.240 --> 00:11:55.960
dramatically altering the types of fish that inhabited ancient oceans
192
00:11:56.000 --> 00:12:00.039
and lakes. What makes this research particularly compelling is that
193
00:12:00.120 --> 00:12:03.320
past studies have failed to identify clear causes for either
194
00:12:03.360 --> 00:12:07.039
extinction event, though both have been linked to ozone layer depletion,
195
00:12:07.519 --> 00:12:11.559
something as supernova could easily trigger. To reach their conclusion,
196
00:12:11.879 --> 00:12:15.840
the research team conducted a census of massive stars within
197
00:12:15.879 --> 00:12:18.440
about three thousand, two hundred and sixty light years of
198
00:12:18.480 --> 00:12:22.480
our Sun. By mapping the distribution of these massive ob stars,
199
00:12:22.919 --> 00:12:25.879
they calculated the rate at which supernova occur in our
200
00:12:25.919 --> 00:12:30.200
cosmic neighborhood. When they compared this data with the timing
201
00:12:30.240 --> 00:12:34.240
of Earth's mass extinctions, they found a compelling correlation that
202
00:12:34.279 --> 00:12:39.039
supports the supernova theory. The researchers describe supernova as both
203
00:12:39.240 --> 00:12:43.279
creators and destroyers of life. They spread heavy elements that
204
00:12:43.360 --> 00:12:46.919
help form and sustain life across the universe, but if
205
00:12:46.960 --> 00:12:49.720
a planet is too close to such an explosion, the
206
00:12:49.759 --> 00:12:53.639
effects can be devastating. Before you start worrying about our
207
00:12:53.639 --> 00:12:57.919
cosmic neighborhood, astronomers believe only two nearby stars could potentially
208
00:12:57.919 --> 00:13:03.279
go supernova within the next million years, and Terry's and Beetlejuice. Fortunately,
209
00:13:03.320 --> 00:13:05.879
both are more than five hundred light years away, and
210
00:13:06.000 --> 00:13:09.960
computer simulations suggests supernova at that distance likely wouldn't affect Earth.
211
00:13:10.960 --> 00:13:14.039
This research not only helps explain Earth's past, but provides
212
00:13:14.159 --> 00:13:17.960
valuable insights into the complex relationship between cosmic events and
213
00:13:18.000 --> 00:13:21.919
life on our planet. Finally, today, have you ever wondered
214
00:13:21.919 --> 00:13:24.639
what stars would sound like if we could hear them. Well,
215
00:13:24.840 --> 00:13:29.360
scientists from UNSW Sydney, Australia have been listening to stars
216
00:13:29.399 --> 00:13:33.320
sing and what they've discovered is giving us unprecedented insights
217
00:13:33.360 --> 00:13:38.080
into stellar evolution. By analyzing the subtle oscillations of twenty
218
00:13:38.120 --> 00:13:41.960
seven stars in a cluster called M sixty seven, located
219
00:13:42.000 --> 00:13:45.440
about two thousand, seven hundred light years away, researchers have
220
00:13:45.559 --> 00:13:49.080
unlocked what they describe as the sounds of stars. These
221
00:13:49.120 --> 00:13:53.399
stellar vibrations, detectable by telescopes as tiny fluctuations in brightness,
222
00:13:53.960 --> 00:13:57.200
act like cosmic fingerprints that reveal a star's age, mass,
223
00:13:57.240 --> 00:14:01.120
and stage of life. What makes this study particularly valuable
224
00:14:01.639 --> 00:14:04.039
is that all these stars were born from the same
225
00:14:04.120 --> 00:14:08.399
gas cloud approximately four billion years ago. They share nearly
226
00:14:08.440 --> 00:14:13.000
identical chemical compositions but differ in mass, providing researchers with
227
00:14:13.039 --> 00:14:16.559
a perfect natural laboratory to observe how stars evolve under
228
00:14:16.559 --> 00:14:20.159
similar conditions. When we study stars in a cluster, we
229
00:14:20.240 --> 00:14:24.200
can see their whole sequence of individual evolution, explains doctor
230
00:14:24.240 --> 00:14:28.240
Claudia Reis, who led the study published in Nature. Though
231
00:14:28.279 --> 00:14:30.960
the same age, their different masses mean they're aging at
232
00:14:30.960 --> 00:14:34.840
different rates, giving scientists a snapshot of various life stages
233
00:14:34.879 --> 00:14:38.600
all in one place. Professor Denis Stello, co author of
234
00:14:38.639 --> 00:14:41.799
the study, likens this process to listening to an orchestra.
235
00:14:42.960 --> 00:14:46.000
The frequency by which an instrument is vibrating depends on
236
00:14:46.039 --> 00:14:49.039
the physical properties of the matter that the sound travels through.
237
00:14:49.519 --> 00:14:53.080
He says stars are the same. You can hear a
238
00:14:53.120 --> 00:14:56.679
star based on how it rings. The biggest stars produce
239
00:14:56.720 --> 00:15:00.840
the deepest sounds, while smaller stars emit higher pace frequencies.
240
00:15:01.320 --> 00:15:04.759
As stars mature toward becoming red giants, these frequency patterns
241
00:15:04.840 --> 00:15:08.559
change in distinctive ways that track their evolution. This breakthrough
242
00:15:08.600 --> 00:15:12.360
has significant implications. It not only helps us understand what
1
