00:00:00 --> 00:00:02 Avery: Hello and welcome back to Astronomy Daily,
00:00:02 --> 00:00:05 the podcast that brings the cosmos down to
00:00:05 --> 00:00:06 Earth. I'm Avery.
00:00:06 --> 00:00:09 Anna: And I'm Anna. It's great to be with you.
00:00:09 --> 00:00:11 Today we're covering everything from the
00:00:11 --> 00:00:13 potential abundance of Earth like planets to
00:00:13 --> 00:00:16 a truly mind bending theory about our first
00:00:16 --> 00:00:18 contact with alien life.
00:00:18 --> 00:00:20 Avery: Plus, we'll be looking at a record breaking
00:00:20 --> 00:00:22 week for space launches around the globe, a
00:00:22 --> 00:00:25 major milestone for a long serving Mars
00:00:25 --> 00:00:27 orbiter, and an exciting opportunity for
00:00:27 --> 00:00:29 students to contribute to the future of space
00:00:29 --> 00:00:32 exploration. So let's get started.
00:00:32 --> 00:00:32 Anna: Avery.
00:00:32 --> 00:00:34 Let's start with one of the biggest questions
00:00:34 --> 00:00:37 in astronomy. Are we alone? A new study
00:00:37 --> 00:00:40 published in Science Advances suggests that
00:00:40 --> 00:00:42 planets like ours might be far more common
00:00:42 --> 00:00:44 than we previously thought.
00:00:44 --> 00:00:47 Avery: This is the kind of news I love. What's the
00:00:47 --> 00:00:48 new theory behind this?
00:00:48 --> 00:00:51 Anna: It's called the immersion theory. The basic
00:00:51 --> 00:00:53 idea is that the formation of rocky Earth
00:00:53 --> 00:00:56 like planets isn't just a gentle process of
00:00:56 --> 00:00:58 dust clumping together over millions of
00:00:58 --> 00:01:01 years. Instead, it might be kickstarted by a
00:01:01 --> 00:01:04 pretty violent event. A nearby supernova.
00:01:04 --> 00:01:07 Avery: A supernova. Wow. So the death of a star
00:01:07 --> 00:01:09 could trigger the birth of a planet like
00:01:09 --> 00:01:09 ours?
00:01:09 --> 00:01:12 Anna: Exactly. The study proposes that the shock
00:01:12 --> 00:01:15 wave and material from a supernova explosion
00:01:15 --> 00:01:18 can compress a cloud of gas and dust and
00:01:18 --> 00:01:20 inject it with heavy elements. This creates
00:01:20 --> 00:01:23 the perfect conditions for rocky planets rich
00:01:23 --> 00:01:25 in the materials needed for life to form
00:01:25 --> 00:01:26 around a young star.
00:01:26 --> 00:01:29 Avery: That's fascinating. So it's less of a random
00:01:29 --> 00:01:31 accident and more of a predictable outcome of
00:01:31 --> 00:01:34 cosmic events. A what does this mean for the
00:01:34 --> 00:01:36 numbers? How much more common are we talking?
00:01:36 --> 00:01:39 Anna: The estimates are really promising. The study
00:01:39 --> 00:01:41 suggests that anywhere from 10 to
00:01:41 --> 00:01:44 50% of sun like stars could have planetary
00:01:44 --> 00:01:47 systems formed under these conditions. It
00:01:47 --> 00:01:49 basically reframes Earth like planets from
00:01:49 --> 00:01:52 being cosmic rarities to potentially being a
00:01:52 --> 00:01:54 common class of planet throughout the galaxy.
00:01:55 --> 00:01:58 Avery: 50%. Just imagine that. It really
00:01:58 --> 00:01:59 changes your perspective when you look up at
00:01:59 --> 00:02:00 the night sky.
00:02:00 --> 00:02:01 Anna: It does.
00:02:01 --> 00:02:03 And speaking of what might be out there,
00:02:03 --> 00:02:06 another fascinating, exciting new idea has
00:02:06 --> 00:02:08 emerged about what our first contact with an
00:02:08 --> 00:02:11 extraterrestrial civilization might actually
00:02:11 --> 00:02:14 be like. And it's not what you see in the
00:02:14 --> 00:02:14 movies.
00:02:14 --> 00:02:16 Avery: Okay, you have my attention. I'm guessing
00:02:16 --> 00:02:18 it's not a friendly hello.
00:02:18 --> 00:02:21 Anna: Not exactly. David Kipping from
00:02:21 --> 00:02:23 Columbia University has proposed something
00:02:23 --> 00:02:26 called the Eschtachian hypothesis. The core
00:02:26 --> 00:02:29 idea is that our first contact won't be a
00:02:29 --> 00:02:31 typical representative signal from an average
00:02:31 --> 00:02:34 alien civilization. Instead, it's more
00:02:34 --> 00:02:36 likely to be a loud and atypical signal.
00:02:37 --> 00:02:39 Avery: Loud? What does he mean by that, like,
00:02:39 --> 00:02:40 powerful and easy to detect.
00:02:41 --> 00:02:44 Anna: Precisely. The hypothesis suggests that the
00:02:44 --> 00:02:46 first civilization we hear from might be one
00:02:46 --> 00:02:49 in a terminal phase, perhaps facing an
00:02:49 --> 00:02:52 existential crisis or nearing its end. In
00:02:52 --> 00:02:54 a final desperate act, they might unleash a
00:02:54 --> 00:02:57 powerful, information rich beacon into the
00:02:57 --> 00:03:00 cosmos, not necessarily for a reply, but
00:03:00 --> 00:03:03 as a final testament to their existence. A. A
00:03:03 --> 00:03:05 sort of cosmic message in a bottle.
00:03:05 --> 00:03:08 Avery: Wow, that is a sobering, thought. So
00:03:08 --> 00:03:09 we wouldn't be hearing from a thriving
00:03:09 --> 00:03:12 neighbor, but receiving a final broadcast
00:03:12 --> 00:03:14 from a civilization that may no longer exist
00:03:14 --> 00:03:16 by the time we get the message?
00:03:16 --> 00:03:18 Anna: That's the idea. It's based on a pattern we
00:03:18 --> 00:03:21 see in astronomy, where our first discoveries
00:03:21 --> 00:03:23 of a new phenomenon are often the most
00:03:23 --> 00:03:26 extreme or unusual cases, the easiest
00:03:26 --> 00:03:28 ones to spot. The first exoplanets we found
00:03:28 --> 00:03:31 were hot Jupiters, which we now know are not
00:03:31 --> 00:03:33 the most common type of planet.
00:03:33 --> 00:03:35 Avery: Right, that makes sense. The quiet, stable
00:03:35 --> 00:03:38 civilizations might be out there, but they'd
00:03:38 --> 00:03:40 be much harder to find than one. Shouting for
00:03:40 --> 00:03:43 all it's worth. It completely reframes the
00:03:43 --> 00:03:44 search for extraterrestrial intelligence.
00:03:45 --> 00:03:46 Anna: It certainly does.
00:03:47 --> 00:03:49 Now, bringing our focus back a little closer
00:03:49 --> 00:03:52 to home. The skies above Earth are about to
00:03:52 --> 00:03:55 get incredibly busy. We're looking at a,
00:03:55 --> 00:03:57 packed week for space launches from multiple
00:03:57 --> 00:03:59 agencies and companies around the world.
00:04:00 --> 00:04:02 Avery: It really feels like a new golden age for
00:04:02 --> 00:04:04 spaceflight. What are some of the key
00:04:04 --> 00:04:05 missions we should be watching?
00:04:06 --> 00:04:08 Anna: Well, there are some exciting debuts. We're
00:04:08 --> 00:04:11 anticipating the first ever launch of China's
00:04:11 --> 00:04:14 Long March 12A rocket. And South
00:04:14 --> 00:04:17 Korea is set to launch its first commercial
00:04:17 --> 00:04:19 rocket, the Hanbit Nano. Over in
00:04:19 --> 00:04:22 Europe, the Ariane 6 is scheduled to launch
00:04:22 --> 00:04:25 another batch of Galileo navigation
00:04:25 --> 00:04:25 satellites.
00:04:26 --> 00:04:28 Avery: And, you know, it wouldn't be a busy launch
00:04:28 --> 00:04:30 week without SpaceX. I assume they have a few
00:04:30 --> 00:04:31 flights planned.
00:04:32 --> 00:04:34 Anna: Naturally. They have multiple Starlink
00:04:34 --> 00:04:37 missions on the manifest, as usual. But they
00:04:37 --> 00:04:39 aren't the only ones building out satellite
00:04:39 --> 00:04:42 Internet. United Launch alliance, or
00:04:42 --> 00:04:45 ula, has a mission for Amazon's
00:04:45 --> 00:04:47 Project Kuiper Pontellation as well.
00:04:47 --> 00:04:50 Avery: It's a truly global effort. Who else is on
00:04:50 --> 00:04:50 the list?
00:04:50 --> 00:04:53 Anna: We're also expecting launches from Japan's
00:04:53 --> 00:04:56 JAXA and Rocket Lab. And for the human
00:04:56 --> 00:04:59 spaceflight, Blue Origin is planning
00:04:59 --> 00:05:02 another crewed suborbital flight, sending
00:05:02 --> 00:05:04 more citizen astronauts to the edge of space.
00:05:05 --> 00:05:07 It's an amazing time to be a space
00:05:07 --> 00:05:08 enthusiast.
00:05:08 --> 00:05:11 Avery: Absolutely. And all those launches depend on
00:05:11 --> 00:05:13 having reliable infrastructure on the ground.
00:05:13 --> 00:05:15 On that note, there's some surprisingly good
00:05:15 --> 00:05:17 news coming out of the Baikonodrome
00:05:17 --> 00:05:18 Cosmodrome.
00:05:18 --> 00:05:21 Anna: That's right. Russia's space agency
00:05:21 --> 00:05:24 Roscosmos has been working on repairs to a
00:05:24 --> 00:05:26 launch pad that was damaged back in November
00:05:26 --> 00:05:29 during a crewed Soyuz launch. Initially, the
00:05:29 --> 00:05:31 timeline for getting it back in service
00:05:31 --> 00:05:33 looked pretty long, which is.
00:05:33 --> 00:05:36 Avery: A big deal considering how historic and vital
00:05:36 --> 00:05:38 that launch site is. So what's the update?
00:05:38 --> 00:05:41 Anna: The news is excellent. Roscosmos
00:05:41 --> 00:05:43 now expects the pad to be fully operational
00:05:44 --> 00:05:46 by late February 2026.
00:05:46 --> 00:05:49 That's significantly sooner than many had
00:05:49 --> 00:05:51 anticipated, which is great news for the
00:05:51 --> 00:05:54 operational tempo of their launches. It's a
00:05:54 --> 00:05:56 real testament to the engineering teams
00:05:56 --> 00:05:56 working on the problem.
00:05:57 --> 00:05:59 Avery: That really is fantastic news.
00:05:59 --> 00:06:01 Now let's travel from the launch pads of
00:06:01 --> 00:06:03 Earth to the orbit of Mars, where a veteran
00:06:03 --> 00:06:06 spacecraft has just hit an incredible
00:06:06 --> 00:06:06 milestone.
00:06:07 --> 00:06:10 Anna: This is such a wonderful story. NASA's
00:06:10 --> 00:06:12 Mars Reconnaissance Orbiter, or MRO,
00:06:12 --> 00:06:15 which has been circling the Red Planet for
00:06:15 --> 00:06:18 nearly two decades, has just captured its
00:06:18 --> 00:06:21 100th image with its most powerful
00:06:21 --> 00:06:21 camera.
00:06:22 --> 00:06:25 Avery: 100 images. The camera is
00:06:25 --> 00:06:27 HiRISE, right? The high Resolution Imaging
00:06:27 --> 00:06:30 Science Experiment. The level of detail it,
00:06:30 --> 00:06:33 captures is just breathtaking. What did they
00:06:33 --> 00:06:34 choose the photograph for this landmark
00:06:34 --> 00:06:35 image?
00:06:35 --> 00:06:38 Anna: This is the best part. The target wasn't
00:06:38 --> 00:06:41 chosen by a NASA scientist or a principal
00:06:41 --> 00:06:43 investigator. It was suggested by a high
00:06:43 --> 00:06:45 school student through a public outreach
00:06:45 --> 00:06:47 program called HiWish.
00:06:47 --> 00:06:50 Avery: No way. That's brilliant. So anyone can
00:06:50 --> 00:06:52 suggest a target for one of the most powerful
00:06:52 --> 00:06:54 cameras orbiting another planet.
00:06:55 --> 00:06:57 Anna: That's the program. And for its
00:06:57 --> 00:07:00 100th photo, HiRise captured
00:07:00 --> 00:07:03 a stunning view of mesas and dunes in a
00:07:03 --> 00:07:05 region called Syrtis Major. It's a
00:07:05 --> 00:07:08 beautiful image and a fantastic example of
00:07:08 --> 00:07:10 how NASA involves the public in the journey
00:07:10 --> 00:07:11 of exploration.
00:07:12 --> 00:07:14 Avery: What a legacy for that student. And, for the
00:07:14 --> 00:07:15 MRO mission itself.
00:07:16 --> 00:07:18 Anna: And speaking of getting involved in space
00:07:18 --> 00:07:21 exploration, that brings us to our final
00:07:21 --> 00:07:23 story. NASA has just launched a new
00:07:23 --> 00:07:26 competition for college students and it's a
00:07:26 --> 00:07:26 big one.
00:07:27 --> 00:07:28 Avery: Oh, excellent. Tell us about it.
00:07:28 --> 00:07:31 Anna: It's called the Orbit Challenge. That's O R
00:07:31 --> 00:07:34 B I T. The goal is to get college
00:07:34 --> 00:07:37 students to develop innovative solutions that
00:07:37 --> 00:07:40 can be used both for life here on Earth and
00:07:40 --> 00:07:42 for deep space exploration, especially with
00:07:42 --> 00:07:45 an eye towards the Artemis program and future
00:07:45 --> 00:07:46 missions to Mars.
00:07:47 --> 00:07:49 Avery: That sounds like an amazing opportunity. Is
00:07:49 --> 00:07:51 it just conceptual or are they looking for
00:07:51 --> 00:07:52 real technical development?
00:07:53 --> 00:07:56 Anna: It's quite serious. There's a prize
00:07:56 --> 00:07:57 pool of up to
00:07:57 --> 00:07:59 $380.
00:08:00 --> 00:08:02 Students are encouraged to work with NASA's
00:08:02 --> 00:08:05 existing portfolio of patents or to
00:08:05 --> 00:08:07 come up with their own brand new concepts.
00:08:08 --> 00:08:10 They're really looking for the next
00:08:10 --> 00:08:11 generation of innovators.
00:08:11 --> 00:08:14 Avery: That's fantastic. A huge resume builder
00:08:14 --> 00:08:17 and a chance to make a real impact for any
00:08:17 --> 00:08:19 students or educators listening. What's the
00:08:19 --> 00:08:20 deadline?
00:08:20 --> 00:08:23 Anna: Registration is open now and runs until
00:08:23 --> 00:08:26 February 9, 2026. So
00:08:26 --> 00:08:28 there's plenty of time to form a team and
00:08:28 --> 00:08:29 start brainstorming.
00:08:30 --> 00:08:32 Avery: From potentially common Earths to final
00:08:32 --> 00:08:35 alien broadcasts from the jam packed launch
00:08:35 --> 00:08:37 schedule to a student photographed Mars,
00:08:38 --> 00:08:40 it's been another incredible week in space
00:08:40 --> 00:08:43 news. And that just about does it for today's
00:08:43 --> 00:08:44 episode of Astronomy Daily.
00:08:45 --> 00:08:48 Anna: We hope we've given you a few new things to
00:08:48 --> 00:08:50 wonder about. The universe is a vast and
00:08:50 --> 00:08:53 fascinating and we're learning more about it
00:08:53 --> 00:08:54 every single day.
00:08:55 --> 00:08:57 Avery: A huge thank you for tuning in and joining us
00:08:57 --> 00:08:59 on this journey. We'll be back soon with more
00:08:59 --> 00:09:02 news from across the cosmos. I'm Avery.
00:09:02 --> 00:09:05 Anna: And I'm Anna. Until next time, keep
00:09:05 --> 00:09:06 looking up.
00:09:18 --> 00:09:18
