Welcome to Astronomy Daily, your source
0:18
for the latest space and astronomy news.
0:23
Today is Wednesday, January 28th, 2026.
0:26
And we've got a fantastic lineup of stories for you.
0:30
We'll be covering Noah's new solar observatory,
0:33
reaching its destination, looking back
0:36
at how weather played a tragic role in the Challenger
0:39
disaster 40 years ago.
0:41
And discovering how AI is uncovering hidden cosmic treasures
0:45
in Hubble's archives.
0:47
Plus, Venus might be in for a spectacular meteor shower
0:51
We'll explore stellar fireworks at the heart of our galaxy.
0:54
And NASA is giving us a live view
0:56
of the Artemis 2 Moon rocket on the launch pad.
0:59
Let's dive right in.
1:00
Our top story today takes us about a million miles from Earth,
1:04
where Noah's space weather follow-on
1:06
Lagrange 1 Observatory has just arrived
1:08
at its permanent home.
1:10
Anna, this is a pretty significant milestone
1:12
for space weather monitoring, isn't it?
1:16
This observatory reached Lagrange 0.1 or L1 on January 21st,
1:21
after launching back in June 2024.
1:25
Now, for our listeners who might not be familiar,
1:28
L1 is the special gravitational sweet spot
1:31
between Earth and the Sun, about 1.5 million kilometers
1:36
And what makes this location so ideal for watching the Sun?
1:40
Well, at L1, the observatory maintains
1:43
a constant view of the Sun while orbiting in sync with Earth.
1:47
It's like having a cosmic early warning system.
1:51
The satellite can detect solar storms and coronal mass
1:54
ejections headed our way, giving us
1:56
that crucial advanced notice, typically about 15 to 60 minutes
2:01
before these events impact Earth.
2:03
That advanced warning time is critical, isn't it?
2:06
I mean, we're talking about protecting everything
2:08
from power grids to satellites.
2:11
And here's what's really exciting.
2:13
It's not just one observatory.
2:15
It's a constellation.
2:17
Noah is planning four more satellites for L1
2:20
plus additional ones at Lagrange.5.
2:23
Together, they'll create this comprehensive solar monitoring
2:28
The second satellite is already scheduled
2:32
So we're looking at a much more robust space weather forecasting
2:35
capability in the near future.
2:38
And given how dependent our modern infrastructure
2:41
is on satellites and power grids,
2:43
this kind of monitoring becomes more important every year.
2:47
The observatory is now beginning what Noah calls
2:50
an extended checkout period before it becomes fully
2:54
Moving to a more somber note, January 28 marks
2:58
40 years since the Space Shuttle Challenger disaster.
3:01
Anna, there's been renewed focus on how
3:03
weather and engineering decisions
3:05
played into that tragedy.
3:07
And it's a powerful reminder of how critical environmental
3:11
factors are in spaceflight.
3:13
You know, Avery, the night before that launch,
3:15
temperatures at Kennedy Space Center
3:17
dropped to just 28 degrees Fahrenheit.
3:20
That's minus two Celsius.
3:22
For Florida, that was exceptionally cold.
3:25
And those cold temperatures were at the heart
3:27
of the problem, weren't they?
3:29
Engineers from Morton Thichal, the company
3:32
that built the solid rocket boosters,
3:34
were deeply concerned about the O-rings,
3:36
these critical rubber seals in the booster joints.
3:39
They'd never been tested below 53 degrees Fahrenheit.
3:43
And the engineers warned that the cold
3:45
could make them too stiff to seal properly.
3:48
But the launch went ahead anyway.
3:50
Despite the engineering concerns,
3:52
there was enormous pressure to maintain the launch schedule.
3:56
NASA had already postponed the mission several times.
3:59
And there was this institutional momentum to proceed.
4:03
73 seconds after liftoff, hot gases
4:06
escaped through a failed O-ring seal,
4:08
leading to the catastrophic breakup of Challenger.
4:13
Seven crew members lost.
4:15
Including Christa McAlliff,
4:16
who would have been the first teacher in space.
4:19
The tragedy fundamentally changed how NASA
4:22
approached decision making.
4:23
The Rogers Commission investigation
4:25
that followed was incredibly thorough.
4:28
And it led to major reforms in safety culture
4:33
One of the key findings was that engineering concerns
4:36
need to override schedule pressures, always.
4:40
And those lessons still resonate today, don't they?
4:42
I mean, we see NASA taking extra time
4:45
with Artemis missions being very methodical.
4:49
The Challenger disaster taught us that in space flight,
4:52
there's no such thing as a routine launch.
4:55
Every mission requires the same level of scrutiny
4:59
and respect for engineering limits.
5:01
It's a lesson paid for with seven lives.
5:04
And one, we must never forget.
5:07
let's talk about some exciting discoveries
5:10
from the Hubble Space Telescope.
5:12
Anna, artificial intelligence has just helped astronomers
5:16
uncover hundreds of previously undetected cosmic objects
5:21
in Hubble's vast archives.
5:23
This is fascinating stuff, Avery.
5:25
So researchers have developed this AI algorithm
5:29
that can sift through decades of Hubble observations
5:32
and it's finding things that human astronomers missed.
5:36
The algorithm focuses on something called gravitational lensing
5:40
when a massive object like a galaxy cluster
5:43
bends light from more distant objects behind it.
5:46
Einstein predicted this effect
5:48
and it's like having a natural cosmic magnifier.
5:51
And these lensed objects can tell us
5:53
a lot about the early universe, right?
5:57
The AI has identified hundreds of gravitational lens candidates,
6:01
including some exceptionally distant galaxies
6:04
from when the universe was very young.
6:06
What's really clever about this approach
6:08
is that the algorithm was trained on existing
6:11
verified gravitational lenses.
6:13
So it knows what to look for.
6:15
So it's not just finding more of the same,
6:18
it's finding rare and unusual examples too.
6:21
That's what makes this so exciting.
6:23
The AI is uncovering exotic lensing configurations
6:27
that would be extremely time consuming for humans
6:31
We're talking about complex multi-image systems,
6:34
arc-like structures, even Einstein rings
6:37
where the background object is perfectly aligned.
6:40
And Hubble has been collecting data for over 30 years now,
6:44
so there's this enormous archive to mine.
6:47
Right, it's like having a treasure trove
6:49
that we're only now learning how to properly search.
6:52
These discoveries will help us understand
6:54
dark matter distribution in galaxy clusters,
6:57
study extremely distant galaxies
6:59
that would otherwise be too faint to detect
7:02
and refine our models of cosmic evolution.
7:05
It really shows how AI and human astronomers can work together.
7:10
The AI does the heavy lifting of searching
7:12
through millions of images,
7:14
and then human experts verify and study
7:16
the most interesting candidates.
7:20
It's not replacing astronomers,
7:21
it's amplifying what they can achieve.
7:24
And as these AI tools get more sophisticated,
7:26
who knows what other cosmic secrets might be hiding
7:29
in plain sight in our archives?
7:31
Now for something you don't hear every day.
7:34
Venus might be getting a meteor shower.
7:37
Avery, tell us about this cosmic event coming this July.
7:41
This is a really cool story, Anna.
7:43
Astronomers have determined that Venus could experience
7:46
a significant meteor shower in July, 2026,
7:50
and it all traces back to an asteroid breakup
7:53
that happened long ago.
7:55
We're talking about debris from asteroid 2002-VT37.
8:01
Though an asteroid broke apart,
8:03
and now its debris is going to hit Venus.
8:08
When asteroids collide or break apart,
8:11
they create streams of debris
8:13
that continue orbiting the Sun.
8:15
Earth regularly passes through these debris streams.
8:17
That's what causes our meteor showers
8:19
like the Perseids or the Geminiids.
8:22
But we don't usually think about other planets
8:24
having meteor showers.
8:26
We don't, and that's partly
8:28
because we can't observe them as easily.
8:30
But mathematical modeling shows that Venus' orbit
8:33
will take it through this particular debris stream in July.
8:37
The timing and geometry appear to line up
8:40
for a genuine meteor shower event.
8:43
What would that look like?
8:44
I mean, Venus has that incredibly thick atmosphere, right?
8:49
Venus' atmosphere is about 90 times denser than Earths,
8:53
and is mostly carbon dioxide.
8:55
Any meteors entering that atmosphere
8:57
would experience tremendous heating and friction.
9:00
They'd likely burn up at much higher altitudes
9:03
than meteors do on Earth,
9:04
creating bright streaks across the Venusian sky.
9:08
Though I suppose nobody's going to be on the surface
9:10
watching this light show.
9:12
No, surface conditions on Venus are pretty inhospitable.
9:16
We're talking temperatures hot enough to melt lead
9:19
and crushing atmospheric pressure.
9:21
But spacecraft in orbit around Venus
9:24
or even Earth-based observations
9:26
with certain wavelengths might be able
9:28
to detect evidence of the meteor shower.
9:30
Could this tell us anything scientifically valuable?
9:34
Studying how meteor showers interact
9:37
with Venus' unique atmosphere
9:39
could give us insights into atmosphere, chemistry,
9:43
Plus, it helps us understand the distribution of debris
9:46
throughout the inner solar system.
9:48
And it's just a reminder that these dramatic cosmic events
9:51
aren't exclusive to Earth.
9:53
Beaking of dramatic cosmic events,
9:56
let's head to the center of our own galaxy.
9:58
Avery astronomers have been observing
10:00
what they're calling stellar fireworks
10:02
at the heart of the Milky Way.
10:04
The Galactic Center is such a wild place, isn't it?
10:08
I mean, we've got that supermassive black hole,
10:10
Sagittarius A-Star,
10:12
and all sorts of extreme physics going on there.
10:15
It really is cosmic chaos in the best way possible.
10:19
The region around Sagittarius A-Star
10:21
is incredibly dense with stars, gas, and dust.
10:25
And what astronomers are seeing
10:26
is a spectacular display of stellar activity.
10:29
Massive stars being born, living out their brief,
10:33
but brilliant lives, and dying in supernova explosions.
10:36
And all of this is happening
10:38
in a relatively small region of space, right?
10:42
The Galactic Center is an incredibly compact environment.
10:45
You've got stellar densities that are millions of times higher
10:48
than what we see in our solar neighborhood.
10:51
Stars are packed so tightly
10:53
that gravitational interactions are common,
10:55
and the radiation environment is intense.
10:58
What kind of observations are revealing these fireworks?
11:01
Astronomers are using multiple wavelengths,
11:03
infrared, X-ray, and radio observations
11:06
to peer through the thick dust
11:08
that obscures the Galactic Center in visible light.
11:11
What they're seeing are energetic outbursts,
11:13
shock waves from supernova remnants,
11:16
and evidence of stars being torn
11:18
apart by intense tidal forces
11:20
near the black hole.
11:21
That sounds pretty dramatic.
11:24
Stars being torn apart?
11:26
Yes, there's this phenomenon called tidal disruption,
11:29
where star that ventures too close to Sagittarius A star
11:32
gets stretched by gravitational forces,
11:35
sort of like cosmic spegetification.
11:38
The star literally gets pulled apart,
11:40
and some of that material falls into the black hole
11:43
while the rest is ejected at tremendous speeds.
11:46
And we're also seeing new stars forming
11:48
in this extreme environment.
11:50
You're, despite the harsh conditions,
11:52
or perhaps because of them,
11:54
there are regions of intense star formation.
11:57
The gravitational compression from all that mass
12:00
can trigger the collapse of gas clouds,
12:02
leading to new stellar births.
12:04
These tend to be very massive hot stars
12:07
that burn bright and die young.
12:09
It's almost like the Galactic Center
12:11
is this constant cycle of creation and destruction.
12:15
That's a perfect way to describe it.
12:17
And studying this region helps us understand
12:19
how galaxies evolve, how supermassive black holes
12:22
influence their surroundings,
12:24
and what conditions were like in the early universe
12:26
when star formation was much more vigorous everywhere.
12:29
For our final story, let's come back closer to home.
12:33
NASA has launched a 24-hour live stream
12:36
showing the Artemis II moon rocket
12:38
on the launch pad at Kennedy Space Center.
12:40
This is pretty exciting for space enthusiasts, savory.
12:43
The space launch system rocket
12:45
with the Orion spacecraft is now stacked
12:48
and standing on launch pad 39B,
12:50
and anyone can watch it live whenever they want.
12:54
This is the mission that will send astronauts
12:56
around the moon, right?
12:57
The first crewed lunar mission since Apollo 17.
13:01
Artemis II will carry four astronauts.
13:04
NASA astronauts Reed Wiseman, Victor Glover, Christina Koch,
13:08
and CSA astronaut Jeremy Hanson
13:11
on a journey around the moon.
13:13
They won't land, but they'll perform a lunar flyby
13:15
before returning to Earth.
13:17
And having the rocket on the pad now,
13:20
that means we're getting close to launch.
13:22
Well, the current target is no earlier than April 2026,
13:26
though space missions often face schedule adjustments.
13:30
Right now, the rocket is on the pad for integrated testing,
13:33
making sure all the systems work together properly
13:36
before committing to a launch attempt.
13:38
What kind of testing are they doing?
13:40
They're running through what's called a wet dress rehearsal,
13:43
which involves loading the rocket with propellants
13:46
and going through the countdown sequence,
13:48
stopping just short of ignition.
13:50
It's essentially a full launch simulation
13:53
to verify that all systems, ground equipment,
13:55
and procedures work as planned.
13:58
And the live stream lets us watch all this happening
14:03
It's a continuous feed, so you can check in at any time,
14:06
day or night, and see the rocket standing there
14:10
Sometimes you'll catch technicians working,
14:13
other times you might see weather rolling through.
14:16
It's a unique behind-the-scenes look
14:18
at the preparation for this historic mission.
14:21
I have to say, there's something on-spiring
14:23
about seeing that massive rocket just standing there,
14:27
ready to take humans beyond Earth orbit
14:29
for the first time in over 50 years.
14:33
And it represents years of work by thousands of people.
14:37
After Artemis II's Lunar flyby,
14:39
Artemis III will attempt the first crude lunar landing
14:42
since 1972, including landing the first woman
14:46
and first person of color on the moon.
14:49
It's a new chapter in lunar exploration,
14:51
and we're watching it unfold in real time, literally.
14:55
We'll put a link in the show notes
14:56
if you'd like to check it out.
14:58
And that wraps up today's episode of Astronomy Daily,
15:01
from solar observatories reaching their cosmic outposts
15:05
to remembering hard-learned lessons
15:07
from AI discoveries and telescope archives
15:10
to potential meteor showers on Venus,
15:12
stellar fireworks at our Galactic Center,
15:15
and moon rockets on the launch pad.
15:17
It's been quite a journey through the cosmos today.
