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