Transcript
- 0:00Hello and welcome to Astronomy Daily,
- 0:03the podcast that brings the universe
- 0:05down to Earth. I'm your host, Avery.
- 0:08>> And I'm Anna. It's great to be with you
- 0:10all again. Avery, the cosmos has been
- 0:13busy and we have some great stories for
- 0:15you.
- 0:16>> You are not kidding. We're talking about
- 0:18a historic change at the top of NASA, a
- 0:21super massive black hole on the run,
- 0:23incredible news from Mars, a
- 0:26surprisingly active moon, and a major
- 0:29leap forward for European space flight.
- 0:32Where do we even begin?
- 0:33>> Let's start here on Earth with a big
- 0:36leadership announcement. It's been
- 0:38confirmed that billionaire entrepreneur
- 0:40and astronaut Jared Isaacman will be the
- 0:43next head of NASA.
- 0:45>> That is huge news. I mean, this is the
- 0:47guy behind the Inspiration 4 and Polaris
- 0:50Dawn missions. He's not just a funer.
- 0:53He's actually flown to space.
- 0:55>> Exactly. And that background is what
- 0:57makes this appointment so fascinating.
- 1:00Isaacman brings a deep understanding of
- 1:02the commercial space sector. This
- 1:04signals a potential acceleration of the
- 1:07partnership between NASA and private
- 1:09companies like SpaceX, Blue Origin, and
- 1:12others,
- 1:13>> right? A shift in focus. So, we might
- 1:16see more commercially driven missions,
- 1:18maybe faster development cycles for new
- 1:20technologies.
- 1:21>> That seems to be the expectation. His
- 1:24supporters believe his entrepreneurial
- 1:26spirit could streamline some of NASA's
- 1:28larger projects like the Aremis program.
- 1:31However, some in the scientific
- 1:33community are cautiously optimistic,
- 1:36hoping the AY's core mission of pure
- 1:38scientific research remains a top
- 1:41priority.
- 1:42>> It's a balancing act for sure. It will
- 1:44be incredibly interesting to see how his
- 1:46leadership shapes NASA's direction over
- 1:48the next few years. Okay, from
- 1:51leadership on Earth, let's head out to
- 1:53the truly wild frontiers of space. Anna,
- 1:56you have to tell us about this runaway
- 1:58black hole. This story is just
- 2:01breathtaking. Astronomers using the
- 2:03James Webb telescope have confirmed
- 2:06something they've never seen before. A
- 2:08super massive black hole weighing as
- 2:11much as 20 million suns hurtling through
- 2:14intergalactic space.
- 2:16>> Wow. How fast are we talking?
- 2:19>> It's moving at about 2.2 million miles
- 2:22hour. Fast enough to travel from the
- 2:24Earth to the moon in about 6 minutes.
- 2:27>> That is absolutely mindbending. But
- 2:30that's not even the wildest part, is it?
- 2:32>> Not at all. The most stunning part is
- 2:35what it's leaving behind. As this black
- 2:37hole plows through the gas between
- 2:39galaxies, it's compressing that material
- 2:42and triggering a massive wave of star
- 2:44formation, it's dragging a tail of
- 2:47newborn stars behind it that is 200,000
- 2:51lightyears long.
- 2:52>> 200,000 light years. That's twice the
- 2:55diameter of our own Milky Way galaxy.
- 2:58Just a tail of stars. So, it's both a
- 3:01force of destruction and creation at the
- 3:03same time.
- 3:04>> Precisely. The theory is that this
- 3:07happened because of a massive cosmic
- 3:09collision. Two galaxies merged and their
- 3:12central super massive black holes began
- 3:14to orbit each other. Then a third galaxy
- 3:17joined the fray and a complex
- 3:20gravitational dance ejected one of the
- 3:22black holes, sending it careening out of
- 3:24its home galaxy.
- 3:26>> It's like a gravitational slingshot on a
- 3:28galactic scale. An incredible discovery
- 3:31and what a testament to the power of the
- 3:33JWST. It really is. Now, let's bring our
- 3:37focus a little closer to home to our
- 3:40neighbor Mars, where another NASA
- 3:42mission is making history.
- 3:44>> Yes, let's talk about the Perseverance
- 3:46rover. This machine is just an absolute
- 3:49marathon runner. NASA recently announced
- 3:52it has traveled almost 25 miles across
- 3:54the surface of Mars.
- 3:56>> Mhm. And after several years in a harsh
- 3:59environment, it's still in excellent
- 4:01condition. This mission has been a huge
- 4:03success for autonomous navigation.
- 4:06Perseverance is making many of its own
- 4:08driving decisions to avoid hazards,
- 4:10which allows it to cover ground much
- 4:12faster than previous rovers.
- 4:14>> It's an explorer in the truest sense.
- 4:17And it's not just driving, it's doing
- 4:19some groundbreaking science. Tell us
- 4:22about the margin unit.
- 4:23>> Right. So, Perseverance has been
- 4:25exploring this area at the edge of
- 4:27Jezero crater called the margin unit.
- 4:30It's a geological treasure trove. The
- 4:33rover has been analyzing rocks rich in
- 4:36olivine, a mineral that on Earth is
- 4:38often associated with water.
- 4:40>> Okay, so olivine plus water. That's
- 4:43always an exciting combination in the
- 4:45search for life.
- 4:46>> Indeed, the data suggests these rocks
- 4:48interacted with liquid water and carbon
- 4:51dioxide from the Martian atmosphere over
- 4:53long periods. By studying these
- 4:56interactions, scientists can piece
- 4:58together what the Martian environment
- 5:00was like billions of years ago and
- 5:02assess whether it could have supported
- 5:04microbial life.
- 5:05>> And Perseverance has been drilling
- 5:07samples from these rocks, right, to
- 5:09eventually bring back to Earth.
- 5:11>> Yes, it has been collecting a diverse
- 5:13library of rock cores. The Mars sample
- 5:16return mission is still in development.
- 5:18But when those samples finally get into
- 5:20labs here on Earth, they could
- 5:22fundamentally change our understanding
- 5:24of Mars and the potential for life
- 5:26beyond our planet.
- 5:28>> An amazing mission that just keeps on
- 5:30giving. All right, let's hop from Mars
- 5:32to our own moon, which is apparently not
- 5:35the quiet, unchanging world we thought
- 5:37it was.
- 5:38>> That's right. New highresolution images
- 5:41from NASA's Lunar Reconnaissance Orbiter
- 5:43or LRO have revealed massive cracks on
- 5:47the moon's surface. These features are
- 5:49called grains and they're essentially
- 5:51trenches formed when the crust is pulled
- 5:54apart.
- 5:54>> Okay, so the crust is fracturing. What's
- 5:57causing that?
- 5:58>> These particular grabins are located
- 6:00around Mari Humorum Basin, an area that
- 6:03was once filled with volcanic lava. As
- 6:06this immense sea of lava cooled and
- 6:08solidified over millions of years, it
- 6:11contracted. This contraction put immense
- 6:14stress on the surrounding crust, causing
- 6:16it to buckle and fracture, forming these
- 6:19long linear valleys.
- 6:21>> So, this is ancient history then from
- 6:23when the moon was volcanically active.
- 6:25>> Well, this is the surprising part. While
- 6:28the process started long ago, analysis
- 6:30of the images shows that some of these
- 6:32grains are remarkably young in
- 6:34geological terms. Some might be less
- 6:37than 50 million years old.
- 6:39>> 50 million years. That's practically
- 6:41yesterday in geological time. So, the
- 6:44moon's surface is still actively
- 6:46changing. It's not a dead rock.
- 6:48>> Exactly. It suggests the lunar interior
- 6:51is still cooling and contracting. And
- 6:53these surface features are the evidence.
- 6:56It forces us to rethink the moon as a
- 6:58dynamic evolving world, which has
- 7:00important implications for future
- 7:02long-term habitats and exploration.
- 7:05>> Absolutely fascinating. Okay, for a
- 7:08final story, we're back in Earth orbit,
- 7:10celebrating a major milestone for the
- 7:13European Space Agency.
- 7:14>> Mhm. This is a big one for European
- 7:17Space Autonomy. Just this week, Europe's
- 7:20brand new Aron 6 rocket had its first
- 7:22operational launch and it was a complete
- 7:25success.
- 7:26>> I know they've been waiting for this for
- 7:28a long time. After the retirement of
- 7:30Aron 5, there was a gap in Europe's
- 7:32independent launch capability. This must
- 7:34be a huge relief.
- 7:36>> A massive relief. For the past couple of
- 7:38years, Europe has had to rely on other
- 7:40providers, including SpaceX, to launch
- 7:43its critical satellites. The successful
- 7:45launch of Aron 6 restores their ability
- 7:48to independently access space, which is
- 7:51crucial for both commercial and
- 7:53strategic reasons.
- 7:54>> So, what was on this inaugural flight?
- 7:56>> The rocket carried two new satellites
- 7:58for the Galileo constellation. This is
- 8:00Europe's global navigation satellite
- 8:02system, their equivalent of the American
- 8:05GPS. Adding these new satellites
- 8:07enhances the systems accuracy,
- 8:10reliability, and coverage. So, this
- 8:12isn't just a win for the rocket program,
- 8:14but also for the millions of people who
- 8:16will rely on the Galileo system for
- 8:18everything from navigating their cars to
- 8:20critical emergency services.
- 8:22>> That's it. It's a dual victory that
- 8:25solidifies Europe's position as a major
- 8:27player in the global space industry. A
- 8:30really significant step forward.
- 8:32>> What a fantastic roundup. From new
- 8:34leadership at NASA to cosmic fugitives
- 8:37and evolving worlds right in our
- 8:39backyard. It just goes to show that
- 8:42there is always something new to
- 8:44discover. Every day brings a revelation
- 8:46that reshapes our understanding of the
- 8:49universe.
