00:00:00 --> 00:00:03 Anna: Welcome to Astronomy Daily, your go to
00:00:03 --> 00:00:05 podcast for the latest in space and astronomy
00:00:05 --> 00:00:08 news. I'm Anna, and joining me as
00:00:08 --> 00:00:11 always, is my co host and fellow space
00:00:11 --> 00:00:14 enthusiast Avery. How's it going, Avery?
00:00:14 --> 00:00:16 Avery: Hey, Anna. And hello to all our listeners out
00:00:16 --> 00:00:19 there. I'm doing great, especially with
00:00:19 --> 00:00:21 today's lineup of stories. We've got some
00:00:21 --> 00:00:23 exciting developments, from rocket tech to
00:00:23 --> 00:00:26 cosmic mysteries. It's like the universe is
00:00:26 --> 00:00:27 putting on a show just for us.
00:00:28 --> 00:00:31 Anna: Absolutely. Today we're diving into
00:00:31 --> 00:00:34 five fascinating a German
00:00:34 --> 00:00:37 company's push to revolutionize European
00:00:37 --> 00:00:39 space launches, a new armor tech to
00:00:39 --> 00:00:42 protect against space debris, insights
00:00:42 --> 00:00:45 into how black holes fire off powerful
00:00:45 --> 00:00:48 jets, a surprising twist on white
00:00:48 --> 00:00:51 dwarf stars, and a tale of a mistaken
00:00:51 --> 00:00:53 gold nugget that's actually from outer
00:00:53 --> 00:00:56 space. We'll break them down, discuss what
00:00:56 --> 00:00:59 they mean, and keep things real with the
00:00:59 --> 00:01:00 science. Let's jump in.
00:01:01 --> 00:01:03 Avery: First up, some big news from the European
00:01:03 --> 00:01:06 space scene. High Impulse, a German
00:01:06 --> 00:01:08 rocket builder, just announced the secured
00:01:08 --> 00:01:11 Euro 45 million in funding to speed
00:01:11 --> 00:01:14 up development of their SL1 rocket.
00:01:14 --> 00:01:16 This three stage beast is 33
00:01:16 --> 00:01:19 meters tall and can haul up to 600
00:01:19 --> 00:01:22 kilograms to low earth orbit using
00:01:22 --> 00:01:25 hybrid motors fueled by paraffin and liquid
00:01:25 --> 00:01:28 oxygen. They're aiming for a debut flight
00:01:28 --> 00:01:30 in 2027. And they've got an optional
00:01:30 --> 00:01:33 space tug called High Move for
00:01:33 --> 00:01:35 dropping payloads into different orbits.
00:01:36 --> 00:01:39 Anna: That's impressive. High Impulse's CEO
00:01:39 --> 00:01:41 Christian Schreier said this will help make
00:01:41 --> 00:01:44 Europe more independent and competitive in
00:01:44 --> 00:01:47 space access. But let's put this in context.
00:01:47 --> 00:01:49 Europe already has heavy hitters like
00:01:49 --> 00:01:52 Ariane6, which can lift over
00:01:52 --> 00:01:55 21 tons in its beefier version, and
00:01:55 --> 00:01:56 and Vega C for up to
00:01:56 --> 00:01:59 2kg. Still, with only
00:01:59 --> 00:02:02 a handful of launches this year due to
00:02:02 --> 00:02:04 delays, there's room for smaller, more
00:02:04 --> 00:02:07 agile options like SL1
00:02:07 --> 00:02:10 to fill gaps, especially for smaller payloads
00:02:10 --> 00:02:12 that might otherwise hitch a ride on foreign
00:02:12 --> 00:02:13 rockets.
00:02:13 --> 00:02:16 Avery: Totally agree. It's not about replacing the
00:02:16 --> 00:02:19 big guns, but adding flexibility. Europe
00:02:19 --> 00:02:21 accounted for less than 1% of global launches
00:02:21 --> 00:02:24 in 2024 per per recent reports,
00:02:24 --> 00:02:27 partly because some missions went to SpaceX.
00:02:27 --> 00:02:30 If high impulse pulls this off, it could
00:02:30 --> 00:02:32 reduce the dependency and boost the
00:02:32 --> 00:02:35 continent's space economy. Exciting times for
00:02:35 --> 00:02:36 European rocketry.
00:02:36 --> 00:02:39 Anna: Moving on to protecting our assets in
00:02:39 --> 00:02:42 orbit. Atomic 6, a Georgia based
00:02:42 --> 00:02:45 company, has unveiled Space Armor,
00:02:45 --> 00:02:48 a new composite material designed to shield
00:02:48 --> 00:02:50 satellites and astronauts from space space
00:02:50 --> 00:02:53 debris. This stuff is lightweight, comes
00:02:53 --> 00:02:56 in customizable tiles, and unlike
00:02:56 --> 00:02:59 traditional metal shields, it absorbs
00:02:59 --> 00:03:01 impacts without creating secondary
00:03:01 --> 00:03:02 fragments.
00:03:02 --> 00:03:05 Avery: Yeah, space junk is a huge problem.
00:03:05 --> 00:03:07 Millions of Tiny particles zipping around at
00:03:07 --> 00:03:10 over 16 miles per hour. The old
00:03:10 --> 00:03:13 Whipple shield invented back in the 1940s
00:03:13 --> 00:03:16 sacrifices itself but spits out more
00:03:16 --> 00:03:18 debris where worsening the Kessler syndrome
00:03:18 --> 00:03:21 where collisions snowball space armor
00:03:21 --> 00:03:23 uses a fiber to resin method to dissipate
00:03:23 --> 00:03:26 energy cleanly. And it's transparent to radio
00:03:26 --> 00:03:28 signals, so I won't Mess with Comms.
00:03:29 --> 00:03:32 Anna: CEO Trevor Smith said it took 18
00:03:32 --> 00:03:35 months to develop and tests showed it
00:03:35 --> 00:03:37 handling Mach 21 impacts with
00:03:37 --> 00:03:40 zero debris. They're planning orbital
00:03:40 --> 00:03:43 tests next year using real debris
00:03:43 --> 00:03:45 as natural hypervelocity guns.
00:03:46 --> 00:03:48 This could be a game changer for safer
00:03:48 --> 00:03:51 missions, Especially in crowded low Earth
00:03:51 --> 00:03:51 orbit.
00:03:52 --> 00:03:54 Avery: For sure, imagine suiting up astronauts or
00:03:54 --> 00:03:57 encasing satellite batteries with this
00:03:57 --> 00:03:59 lighter, stronger and debris free.
00:03:59 --> 00:04:02 It's a smart evolution in space tech Building
00:04:02 --> 00:04:04 on composites potential to make orbits more
00:04:04 --> 00:04:05 sustainable.
00:04:06 --> 00:04:08 Now let's get cosmic with black holes.
00:04:08 --> 00:04:11 Researchers at Goda University have used
00:04:11 --> 00:04:13 advanced simulations to explain how
00:04:13 --> 00:04:16 supermassive black holes predict produce
00:04:16 --> 00:04:18 those massive relativistic jets Streams of
00:04:18 --> 00:04:21 plasma shooting out at near light speeds
00:04:21 --> 00:04:23 stretching thousands of light years.
00:04:23 --> 00:04:26 Anna: The key is the Blandford Zenok mechanism.
00:04:26 --> 00:04:29 A spinning black hole twists magnetic fields
00:04:29 --> 00:04:32 in its accretion disk, Converting rotational
00:04:32 --> 00:04:35 energy into electromagnetic power that
00:04:35 --> 00:04:37 launches the jets. But the new twist
00:04:38 --> 00:04:40 magnetic reconnection where field
00:04:40 --> 00:04:43 lines snap and release energy
00:04:43 --> 00:04:46 Plays a big role too, Creating plasmoids
00:04:46 --> 00:04:47 that boost the process.
00:04:48 --> 00:04:50 Avery: Their Frankfurt particle in cell code
00:04:50 --> 00:04:53 simulated this on supercomputers, showing how
00:04:53 --> 00:04:55 these events extract energy efficiently.
00:04:55 --> 00:04:58 Professor Luciano Rizzola noted it explains
00:04:58 --> 00:05:01 the extreme brightness of active galactic
00:05:01 --> 00:05:03 nuclei and particle acceleration.
00:05:03 --> 00:05:06 Observations like the Event Horizon
00:05:06 --> 00:05:08 TeleScope's image of M87's black hole
00:05:08 --> 00:05:11 back this up with with its jet extending
00:05:11 --> 00:05:12 5 light years.
00:05:13 --> 00:05:15 Anna: This isn't just cool jets influence
00:05:16 --> 00:05:18 galaxy evolution by dispersing energy
00:05:18 --> 00:05:21 and affecting star formation. It
00:05:21 --> 00:05:24 shows black holes as dynamic engines,
00:05:24 --> 00:05:26 not just sinks. Dr. Claudio
00:05:26 --> 00:05:29 Marengolo said these sims reveal
00:05:29 --> 00:05:32 the interplay of gravity and magnetism and
00:05:32 --> 00:05:35 extreme environments. Mind blowing
00:05:35 --> 00:05:37 stuff shifting to stellar remnants.
00:05:37 --> 00:05:40 Astronomers have figured out why some white
00:05:40 --> 00:05:43 dwarfs in short period binary systems are
00:05:43 --> 00:05:45 inflated twice as large as expected
00:05:46 --> 00:05:48 and hotter, up to 30
00:05:48 --> 00:05:51 kelvin instead of the usual 4.
00:05:52 --> 00:05:55 These are dense cores left after stars
00:05:55 --> 00:05:58 like our sun die. But in pairs, orbiting
00:05:58 --> 00:06:00 in under an hour, they're far from dead.
00:06:01 --> 00:06:03 Avery: The secret is tidal heating.
00:06:03 --> 00:06:06 Gravitational tugs deform the stars, causing
00:06:06 --> 00:06:09 internal friction heats and expands them,
00:06:09 --> 00:06:11 especially the less massive one. Lead
00:06:11 --> 00:06:14 researcher Lucy McNeil developed a model
00:06:14 --> 00:06:15 showing this lets interactions start at
00:06:15 --> 00:06:18 longer orbital periods up to three times.
00:06:18 --> 00:06:20 Anna: What we thought observations of these hot,
00:06:20 --> 00:06:23 puffy white dwarfs match the predictions.
00:06:23 --> 00:06:25 McNeil was surprised by how much orbits
00:06:25 --> 00:06:27 shrink for the oldest ones before mass
00:06:27 --> 00:06:30 transfer kicks in. This could reshape our
00:06:30 --> 00:06:32 understanding of type 1a supernova
00:06:32 --> 00:06:35 progenitors. These binaries might merge into
00:06:35 --> 00:06:37 those cosmic explosions we use to measure
00:06:37 --> 00:06:39 distances exactly.
00:06:39 --> 00:06:41 Avery: It applies tidal heating from hot Jupiters to
00:06:41 --> 00:06:44 white dwarfs, showing binaries keep evolving
00:06:44 --> 00:06:46 dynamically. Future work on carbon and oxygen
00:06:46 --> 00:06:49 white dwarfs could refine supernova models.
00:06:49 --> 00:06:51 White dwarfs not so dead after all.
00:06:51 --> 00:06:54 Finally, a fun one. Back in 2015,
00:06:54 --> 00:06:57 Australian prospector David Hole found a
00:06:57 --> 00:06:59 heavy reddish rock in Maryborough Park.
00:06:59 --> 00:07:01 Thinking it was a gold nugget, he tried
00:07:01 --> 00:07:04 everything saws, acid, etc. Even a
00:07:04 --> 00:07:07 sledgehammer to crack it open. But no luck.
00:07:07 --> 00:07:10 Anna: Turns out it was a 17 kilogram
00:07:10 --> 00:07:13 meteorite. Museum geologists identified
00:07:13 --> 00:07:15 it as an H5 ordinary
00:07:15 --> 00:07:17 chondrite packed with iron and
00:07:17 --> 00:07:20 chondrules, ancient grains from the solar
00:07:20 --> 00:07:22 system's birth 4.6 billion
00:07:23 --> 00:07:25 years ago. It's the second largest in
00:07:25 --> 00:07:28 Victoria, where only 17 meteorites are
00:07:28 --> 00:07:28 recorded.
00:07:29 --> 00:07:31 Avery: Carbon dating places its earth fall between
00:07:31 --> 00:07:34 100 and 1 years ago, possibly
00:07:34 --> 00:07:36 linked to historical fireball sightings.
00:07:36 --> 00:07:39 Geologist Dermot Henry called it a cheap way
00:07:39 --> 00:07:41 to explore space, with potential organic
00:07:41 --> 00:07:43 molecules hinting at life's building blocks.
00:07:44 --> 00:07:47 Anna: From gold rush disappointment to cosmic
00:07:47 --> 00:07:49 gem, its dimpled surface and density
00:07:49 --> 00:07:52 gave it away, likely from the asteroid belt.
00:07:52 --> 00:07:55 It's a reminder that treasures can fall from
00:07:55 --> 00:07:57 the sky. What a story.
00:07:57 --> 00:08:00 Avery: Ooh, what a packed episode from rocket boosts
00:08:00 --> 00:08:02 to meteorite mix ups. The the universe keeps
00:08:02 --> 00:08:03 delivering.
00:08:03 --> 00:08:06 Anna: Thanks for tuning in to Astronomy Daily. If
00:08:06 --> 00:08:08 you enjoyed, subscribe and share your
00:08:08 --> 00:08:10 thoughts. We'll be back tomorrow with more

00:08:13 --> 00:08:14 Avery: Clear skies
