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