The tale of Jason and the Argonauts is one of the biggest and boldest stories in Greek mythology. And it involves some of the greatest heroes, many of whom are depicted in the stars – from the twins of Gemini to mighty Hercules. The boat itself was placed in the stars as well. But even it was too big. Astronomers eventually split it apart. The original constellation was Argo Navis. It was first drawn almost 3,000 years ago. It was far larger than any of the other ancient western constellations. And for a long time, that was just fine. But as astronomers began studying the stars with telescopes, the Argo was just too big – there were too many stars and other objects within its borders to catalog. In 1756, French astronomer Nicolas Louis de Lacaille decided to do something about it. He split the Argo apart. He kept the references to the boat, though. So his new constellations were Carina, the keel; Vela, the sail; and Puppis, the poop deck – the deck at the back of the boat. And those constellations are still in use today. Carina is best known for its brightest star, Canopus. It’s the second-brightest star in the night sky. And from the southern latitudes of the United States, it crawls low across the south in early evening at this time of year. As night falls, it’s just above the horizon, almost directly below Sirius, the brightest nighttime star. We’ll have more about Canopus tomorrow. Script by Damond Benningfield

"Is this the real life? Is this just fantasy? Caught in a landslide, no escape from reality. Open your eyes, look up to the skies and see." There's something about space that captures the imagination of scientists and artists alike. Just ask astrophysicist Derek Ward-Thompson and astronomer Brian May (yes, THAT Brian May, guitarist of Queen). In their new book Islands in Infinity: Galaxies 3-D, they turn flat images of the galaxies to three dimensional spacescapes that leap off the page.  Host Flora Lichtman talks with Ward-Thompson and May about the enchanting nature of space and the collision of art and astronomy. And yes, they get into the music. Guests: Dr. Brian May is an astronomer and the guitarist of Queen. Dr. Derek Ward-Thompson is an astrophysicist at the University of Lancashire in England.

From clouds of cosmic dust to brand-new worlds, a Nasa fellow explains how scientists are using powerful radio telescopes to watch planets being born.

Something dark and invisible makes up as much as 90 to 95 percent of the universe—and it took a little girl staring out a bedroom window at the night sky to bring it to light. As a child, Vera Rubin built her own telescope. As an adult, she uncovered a problem no telescope could solve: stars at the edges of galaxies were moving just as fast as those near the center. The math contradicted everything astronomers expected to see...unless the universe was filled with unseen matter.This is the story of how Vera Rubin pushed through the gender barriers of the 1950s and turned a fringe idea into one of astronomy's biggest open questions. What is dark matter? How did Rubin help prove it was real? And what does it mean that most of the universe is made of something we can't see?Guests: Ashley Yeager, Associate News Editor at Science News and Author of Bright Galaxies Dark Matter and Beyond: The Life of Astronomer Vera RubinRamona Rubin, Granddaughter of Vera Rubin Deidre Hunter, Astronomer at the Lowell Observatory in Flagstaff, Arizona Amruta Jaodand, Astrophysicist at the Chandra X-Ray Center in the Smithsonian Astrophysical Observatory

Last July, a space telescope heard the death cry of a star billions of light-years away. It was the longest outcry of its type ever detected – an astonishing seven hours. Yet its details are still fuzzy. All we know for sure is that it was a violent ending for a star. The outcry was a gamma-ray burst. Astronomers have discovered thousands of them. They’re usually produced by a supernova – the titanic explosion of a massive star. Energy from the nuclear inferno deep inside the star blasts outward through its poles. That forms narrow jets of gamma rays – the most powerful form of energy. The gamma rays usually last a few seconds or minutes. In that time, though, the burst can emit more energy than the Sun will produce over billions of years. Follow-up observations showed that the July outburst took place in a galaxy that’s giving birth to many stars – perhaps as the result of a merger with another galaxy. Many of the new stars are hot and massive, so they explode quickly. That makes the galaxy a good breeding ground for gamma-ray bursts. But the origin of this event isn’t clear. It could have been the result of a supernova. Other possible scenarios include the merger of a black hole with the dead or stripped core of a Sun-like star, or a close encounter between a star and a mid-sized black hole. Such an encounter would have ripped the star apart, forming a trail of incandescent gas – triggering a long outcry from a dying star. Script by Damond Benningfield

We're going deep today, Slushies. Kathy and Tobi school us on the origin of the word “podcast” with its roots in both early Apple technology and agricultural lingo (think broadcast of seeds). In this episode we're broadcasting our appreciation for poems by Erin Evans. We admire Evans' sound work and her ability to craft powerful lines with plain language. In the first poem, the poet's confrontation of medical jargon reminds Marion of Whitman's poem When I Heard the Learn'd Astronomer. An encounter between patient and doctor in Evans' poem underscores the difference between learning and knowing that recalls Leslie Jamison's book of essays, The Empathy Exams.    The second poem's Japanese title evokes the film Rashomon for Jason, who takes issue with the notion that our writerly imaginations are limited only to the words available in our own language. Schadenfreude, anyone? We're digging the close focus on language in these poems. Marion appreciates that the poem elevates a term she initially passed off as one from pop culture wellness. Meanwhile we conflate our Wabi-sabi with our kintsugi and poet Ross Gay with the poet Ross White (who is the actual originator of the gas station sushi theory). But don't let our mistakes keep you from experiencing Evans' powerful endings.   Slushies, if you're attending AWP in March, please stop by and see us at the book fair. We'll be at table 1272. We'd love to see you in person. Thanks, as always, for listening!   At the table: Tobi Kassim, Jason Schneiderman, Kathleen Volk Miller, Marion Wrenn, Lisa Zerkle, and Lillie Volpe (sound engineer)  Author Photo:    Author Bio: Erin Evans was diagnosed with Cystic Fibrosis when she was one year old. Her work is greatly influenced by her experience living with chronic illness. She has had poems published in Defunct, Revel, A Mouthful of Salt, and Nimrod-International Journal, which awarded her its Francine Ringold Award for New Writers. Her work was chosen by Kwame Dawes for his American Life in Poetry column. She lives in Vermont with her beautiful and brilliant kids. Exacerbation She says the word quickly looking down at my file   then back at the x-ray clipped against the glowing box.   My scarred and patchy lungs, and all their flaws  on display, almost make me blush.   Embarrassed that I couldn't do any better, have been better. I focus instead    on the soft ribbons of my ribcage that fan like ghost hands   lit up for Halloween. Again, she says it,   looking at me now  as she sits on the round rolling chair   and reaches for her stethoscope. Exacerbation, which I finally looked up   after years and years of hearing it, simply means a worsening.   But she was taught not to state  the obvious, to disguise the truth   in the language of textbooks, and lectures, years of learning   how best to look right through someone. And I was taught to breathe in when I was told,   to push past that pain in my chest  that has no name, nor chapter in any book.   Komorebi Scott nudges my kayak away from the shore.   The yellow plastic scrapes the sand and seashell bottom  until it glides to the open water, over deep-green seaweed that waves its version of goodbye.    A soft pushing away  a departing of one world, only to enter another,  so vast there are no names for things:   When I die  let it be like this.   Some languages have words for words we never even thought to speak.   In Japanese, for instance, there is a word  for the sunlight filtering through the leaves of a tree.   Tell me, why isn't there a name for this: The ocean's soft  pull, the gentle begging it does,      like a child tugging  at the tail of your shirt,    reminding you it's time to go.   Riches  As I cradle my morning tea I watch her from the window.   Crouched down in the yard, with her hand outstretched. Even   from here I see the arthritis knot and bend her fingers   from years of knitting intricate sweaters and working late-night shifts at the hospital.   The chickens come to her  hesitantly, to peck the scratch from her warm hand.   She told me once that even when  she has nothing to give them   they still peck softly at her wedding band.   They surround her now, their bobbing and dipping beaks   and as they take the seeds she offers,  she smooths the long yellow feathers   that in the right light turn golden.   If I could inherit a single thing from her it would be this patience,   this trust that life will come to you even when your body    is leaving this world slowly, one cell at a time.

Astronomers may have found the missing link in the story of the Milky Way's most common planets. In this SETI Live, host Moiya McTier is joined by exoplanet scientist John H. Livingston to explore a new discovery that helps connect the dots between small rocky worlds like Earth and the larger "sub-Neptunes" that dominate our galaxy. Using cutting-edge observations and statistical analysis, researchers have identified a population of planets that appears to bridge a long-standing gap in our understanding of planetary formation. For years, astronomers have known that planets of sizes between Earth and Neptune are incredibly common—but their origins and evolutionary paths have remained puzzling. This new result may finally clarify how these worlds form, evolve, and sometimes transform. What does this mean for: • How do planetary systems assemble? • Why does our Solar System look so unusual? • The search for habitable worlds beyond Earth? Join us as we break down the science, the methods, and the bigger implications for exoplanet research and the search for life. Press release: https://www.abc-nins.jp/en/2026/01/08/10010/ Paper: https://www.nature.com/articles/s41586-025-09840-z (Recorded live 26 February 2026.)

The planets in our solar system fit into two groups. Four of the planets are small and rocky; Earth is the largest. The other four are big and bloated; Neptune is the smallest. But there’s nothing between the sizes of Earth and Neptune. And that’s a bit odd. Two of the most common types of planets elsewhere in the galaxy are somewhere in the middle: super-Earths and mini-Neptunes. Astronomers have confirmed more than 6,000 planets in other star systems. Only one system has as many known planets as the solar system does. And the planets in almost all the known systems are packed in much closer to their stars than the worlds of the solar system – in part because close-in planets are the easiest to find. But the biggest difference between our system and all the others appears to be the lack of super-Earths and mini-Neptunes. A super-Earth is up to twice the diameter of Earth, and two to ten times Earth’s mass. Such worlds probably are dense and rocky. They may have thick atmospheres of hydrogen and helium, and perhaps deep oceans of liquid water. Mini-Neptunes are larger than super-Earths, but no bigger than Neptune. They probably have a solid core as well, but thicker layers of gases and liquids. The distinction between the two types of planets isn’t always clear. They probably have a lot in common – including the fact that we don’t have either of them in our own solar system. Script by Damond Benningfield

Astronomers have just spotted something terrifying: a “zombie star” streaking across the Milky Way, and it might be one of the strangest—and most dangerous—objects in our galaxy. Known only as SGR 0501+4516, this cosmic oddity is tearing through space at speeds most rockets could only dream of — and its magnetic power? Let's just say it makes Earth's field look like a fridge magnet. Could this be a new class of celestial monster… or something even weirder? Learn more about your ad choices.

He was a composer, organist, conductor and pianist of the Romantic Era, that's music that was featured throughout the 19th century. He was a musical prodigy, of course. He had perfect pitch. A grand aunt taught him some piano basics at three, and he was a music pupil at the age of 7. He gave informal performances at the age of 5, and his public debut was at age 10 performing the music of Mozart and Beethoven. He and studied at the Paris Conservatoire starting at age 13 to age 18. His first “job” was a ORGANIST at the Saint Merri Church – 26,000 parishioners. That sounds like a typical trajectory for a young musical prodigy. But, unlike other music students, Saint-Saens had a broad focus. He was a multi-tracker of the day, with varying and distinguished interests such as the study of Latin, Greek, Divinity and Mathematics. He was talented amateur Astronomer throughout his adult life.   In today's podcast I review portions of 4 SAINT-SAENS COMPOSITIONS, pieces composed between 1853 and 1886, or when Saint-Saens was from the age of 17 to 50. We will hear 6 movements from 4 works – those 4 works are Symphony No. 1 Symphony No. 2 Symphony No. 3 Carnival of the Animals

Astronomers just found something cool!  Typically, most Sun-like stars host planets between the size of Earth and Neptune called 'super-Earths' or 'sub-Neptunes'. These planets often orbit their stars even closer than Mercury orbits our Sun. They're mostly rocky super-Earths or they have a thick atmosphere and a rocky core and are sub-Neptunes. They're the most common types of planet found in our Galaxy. And yet, astronomers weren't sure exactly how these planets formed.  So yeah, they found something cool!    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

A recent study published in Physical Review Letters suggests that the mysterious high-energy neutrino detected in 2023 may have originated from a quasi-extremal primordial black hole. This type of black hole, theorized to exist since the Big Bang, could explain the otherwise unexplainable energy levels of the neutrino and potentially unlock the secrets of dark matter and the fundamental nature of the universe.Mars' Dust Storms and Water LossNew research published in Communications Earth and Environment reveals that localized dust storms on Mars may play a significant role in the planet's water loss. While Mars is currently a dry desert, evidence from its surface indicates a wetter past. The study shows that intense dust storms can transport water vapor to higher altitudes, facilitating its escape into space, thus contributing to the long-standing mystery of Martian water depletion.Plasma Daniel for Hypersonic TestingA groundbreaking facility known as the plasma tunnel is now being used by scientists and engineers to simulate the extreme conditions spacecraft face during atmospheric reentry. The plasma tunnel generates high-speed plasma flows that mimic the intense heat and pressure experienced during reentry, providing critical data for developing safer and more efficient spacecraft. This innovative technology could revolutionize our understanding of hypersonic flight and enhance mission safety for future space exploration.www.spacetimewithstuartgary.com✍️ Episode ReferencesPhysical Review Letters, Communications Earth and EnvironmentBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support.(00:00:00) Astronomers investigate a potential black hole explosion(00:07:15) New study reveals how dust storms on Mars contribute to water loss(00:15:30) The plasma tunnel: recreating atmospheric reentry conditions(00:22:45) Science report: Genetic factors influencing life expectancy(00:30:00) Bigfoot sightings and cultural phenomena in America

On Thursday's show: Last week, the dean of the University of Houston's College of Liberal Arts and Social Sciences asked faculty he oversees to sign a document attesting they are not "indoctrinating" their students but are instead teaching them to think critically. One of those professors, Robert Zaretzky, responded with an op-ed in the Houston Chronicle saying he will not sign the document. He joins us to explain why.Also this hour: Houston's diversity shows up everywhere, including in foster care. We discuss how families navigate caregiving of children from different cultural backgrounds.Then, we visit this year's ongoing Mardi Gras celebrations in Galveston to learn how they're different from what happens in New Orleans.And, ahead of the Chinese New Year, which begins Feb. 17, we learn more about Chinese Americans' cultural and economic impacts here in Houston. And we talk about some of the Chinese constellations in the night sky with an area astronomer.Watch

HEADLINE: The Rise of Dark Energy. GUEST: Govert Schilling. SUMMARY: After ruling out MACHOs, astronomers discovered the universe's expansion is accelerating, revealing that mysterious Dark Energy dominates the cosmos alongside dark matter. 1959

It’s Super Bowl Day in the US and while we’re not clear on the result, we do know that Kim Kardashian decided it was date night and Bad Bunny is actually one extremely good bunny. So, why did he inspire other musicians to put on a rival halftime show? In other business, the 'Coldplay kiss cam' woman is telling her side of the story of the night that changed her life, and Jessie Stephens, Clare Stephens and Holly Wainwright ask: What do you do with the kind of infamy that no-one wants? And, Recipe Tin Eats’ Nagi Maehashi is mourning the loss of her very good boy, the famous Dozer. Have we learned how to say goodbye to pets properly?

Have we just found the universe's missing matter?Astronomers know exactly how much visible matter the entire universe should contain. The problem is, that for decades, 40% of it has been missing. Nowhere to be found. For the first time in history, we may have finally found where the missing mass of the universe has been hiding… And it's in plain sight.▀▀▀▀▀▀If you love learning about science as much as I do, head to http://brilliant.org/astrum to learn for free for a full 30 days.

Astronomers need your help! And you don't have to be an expert, because it's as easy as stepping outside your home and taking a good look at a constellation like Orion. For 20 years, the citizen science project Globe At Night has helped advance our understanding of light pollution – as scientists figure out how fast stars are disappearing from our sky.

Astronomer Paul Kalas explains planetary formation in the Fomalhaut system twenty-five light years distant, revealing how observations of this nearby star illuminate the processes that create worlds around young suns.SATURN AND SYSTEM

The Earth-sized planet has conditions similar to Mars but its 146 light years away. Dr Chelsea Huang from the University of Southern Queensland in Australia was among the scientists who carried out the research spoke to Rachel.

The Challenger tragedy's 40th anniversary is a time to remember and a time to reflect on the fact that in spite of how it sometimes looks easy, rocket science is hard. Artemis II is getting closer to a possible launch in about 2 weeks. Astronomers are leaning more about exoplanets thanks to the world's largest radio telescope project. Become a supporter of this podcast: https://www.spreaker.com/podcast/made-of-stars--4746260/support.

A CMO Confidential Interview with Rob Ward, co-founder and General Partner of Meritech Capital, a top Silicon Valley venture firm. Rob shares his take on what he calls a "super terrifying and exciting time" and provides perspective on AI receiving the most capital of any technology in history, the "durability of revenue" and how quickly start-ups are now reaching $100 million in revenue. Key topics include: why VC's focus on growth vs. profitability; the risks associated with massive long-term capital investment; why marketers should pick a "trusted advisor" as their AI partner; and why your data strategy needs "context. Tune in to hear how Astronomer handled the "Coldplay Concert Incident" which immediately became a PR classic and the "VC Foie Gras Effect."What happens when a top venture capitalist pulls back the curtain on AI, valuations, hype cycles, and what's actually working?In this episode of CMO Confidential, host Mike Linton sits down with Rob Ward, Co-Founder and General Partner at Metech Capital, to unpack the realities behind the AI boom. Rob has spent more than 26 years investing in category-defining companies like Facebook (Meta), Snowflake, NetSuite, Zipcar, and Cloudera — and he brings a rare, grounded perspective to today's AI frenzy.Together, they explore: • Why AI adoption is still early — despite explosive growth • The real risks behind inflated valuations and “AI-washing” • How VC decision-making changes during platform shifts • What marketers and executives should actually look for when choosing AI partners • Why data strategy, change management, and trust matter more than tools • What layoffs, productivity, and the future of work really look like beneath the headlines • A masterclass in crisis communications, featuring Ryan Reynolds, Gwyneth Paltrow, and ColdplayIf you're a CMO, CEO, board member, founder, or agency leader trying to make sense of AI without getting swept up in the hype — this is a must-listen conversation.New episodes of CMO Confidential drop every Tuesday.Subscribe for insider perspectives on the most misunderstood role in the C-suite.⸻Chapter Markers00:00 – Welcome to CMO Confidential00:19 – Introducing Rob Ward and today's AI conversation01:13 – Where we really are in AI adoption02:26 – Explosive AI growth: what's real vs hype03:35 – Why enterprise AI adoption is still a slog04:37 – Vendor spend, hyperscalers, and the trillion-dollar buildout06:12 – Is this an AI bubble?

Many of the features on the Moon are named for astronomers. So are features on Mars and other planets and moons. And hundreds of asteroids are named for astronomers as well. But you won’t find many features named for astronomers here on Earth. Quite a few streets and schools are named after them. But when it comes to major features, the list is pretty thin – especially in the United States. One of the few is Mount Langley, a 14,000-foot summit in California. It’s named for Samuel Pierpont Langley, who was a long-time director of the Allegheny Observatory. To see more features named for astronomers, though, you need to head south – to Australia, New Zealand, and even Antarctica. In Australia, for example, a river and an estuary are named for Thomas Brisbane, an early governor of the state of New South Wales. And so is the city of Brisbane, the capital of Queensland. In addition to his government duties, Brisbane was an astronomer. He set up Australia’s first major observatory. In New Zealand, several peaks in a large mountain range are named for astronomers, including Galileo and Copernicus. And an entire range is named for Johannes Kepler. In Antarctica, many features are named for James Ross, an early explorer. But Ross himself named several features for astronomers, including Cape Smyth and Mount Lubbock – down-to-earth features named for men who studied the stars. Script by Damond Benningfield

There just aren’t enough superlatives to describe the galaxy OJ 287. It’s a quasar – an especially bright object powered by two supermassive black holes. One of them is about 150 million times as massive as the Sun. The other is 18 billion times the Sun’s mass – one of the heaviest black holes yet seen. They team up to produce outbursts that are a trillion times brighter than the Sun – brighter than all the stars in the Milky Way Galaxy combined. OJ 287 is always bright. But every few years, it flares up – the result of interactions between the black holes. Each of them is encircled by a giant disk of gas. As the gas spirals in, it gets extremely hot. That makes the disks extremely bright. The smaller black hole orbits the larger one every 12 years. The orbit is tilted. So every six years, the black hole plunges through the disk around the larger black hole. That can heat some regions to trillions of degrees, producing the flare-ups. Astronomers recently used radio telescopes to take a picture of the system. They saw a long “jet” of particles from the smaller black hole. The jet is twisted by the interactions between the black holes – confirming the profile of this amazing system. OJ 287 is in Cancer, which is low in the east at nightfall. Even though it’s billions of light-years away, OJ 287 is bright enough to see through most amateur telescopes. Script by Damond Benningfield

You can find Jessica Walker on IG @hellojessicawalker   In this week's episode, we're talking to debut novelist and assistant professor of fine arts at Parsons School of Design Jessica Walker, whose novel Amy discovered late last year. The Secret Astronomers is an illustrated novel, which is not the same as a graphic novel.  This is a novel that is written on sticky notes between two people inside a book.  It's in full color and really eye-catching. Although it is technically geared towards young adults, it is a feast for the eyes for any age reader.  The story is about two girls who keep their identities secret from each other and converse through an old astronomy textbook in the school library. This new take on the epistolary novel takes the reader on an adventure to solve a mystery in this small West Virginia town.     And in our book rec section, inspired by the West Virginia setting of The Secret Astronomers, we're giving you other books set in The Mountain State.

Some Christians believe that God's words in Genesis 1:3, "Let there be light," . . are a biblical description of the Big Bang that some scientists say created the universe. But perhaps we Christians should be a little more careful about assuming that modern science knows very much about the origin of the universe.Astronomers recently announced that they had discovered the largest structure yet to be found in the universe. They described the structure as a great wall made up of high concentrations of galaxies. Just to get our perspective, the average galaxy contains over 1 billion stars. The great wall contains concentrated "clumps" of galaxies!This discovery delivers two apparently fatal blows to the Big Bang theory. If the universe was the result of the Big Bang, scientists would expect to find stars evenly distributed in space, not "clumped" together and certainly not built into giant structures. Second, the clumps of galaxies they found are very precisely and evenly spaced—not the kind of order that results from an explosion. One of the researchers said, "It is safe to say that we understand less than zero about the early universe."There is another good reason for Christians not to try to find the Big Bang in Genesis. According to the Bible, it is the end of the world and the universe, not its beginning, that could more accurately be described as a "big bang." Christ Himself has completed your preparations for that day. Are you ready?Isaiah 34:4"All the hosts of heaven shall be dissolved, and the heavens shall be rolled up like a scroll; all their host shall fall down as the leaf falls from the vine, and as fruit falling from a fig tree."Prayer: Dear Lord; I cling to Your saving work for my preparation for the end of the world. Be with me now and prepare me to spend eternity with You. Amen.REF.: Galaxy clumps' may shed light on cosmic creation. Minneapolis Star Tribune.

We also explore the latest research on Europa, one of Jupiter's moons, and uncover the sources of the sun's mysterious gamma rays.Life's Building Blocks on TitanA groundbreaking study reveals that Titan, Saturn's largest moon, exhibits unexpected chemical interactions at extremely low temperatures. Researchers found that hydrogen cyanide can mix with nonpolar substances like methane and ethane, challenging traditional chemistry principles. This discovery could provide insights into the prebiotic chemistry that may have preceded life on Earth, as Titan's environment mirrors that of early Earth.Europa's Quiet OceansIn a surprising turn, new calculations suggest that the vast subsurface ocean beneath Europa's icy crust may be lifeless. This research indicates that Europa lacks the geological activity, such as hydrothermal vents, necessary to sustain life. Lead author Paul Brian discusses how the moon's stable orbit around Jupiter limits the tidal forces that could drive geological processes, casting doubt on the moon's potential as a habitat for life.The Source of Solar Gamma RaysAstronomers have identified the origin of intense gamma radiation emitted during solar flares, linking it to high-energy electrons colliding with plasma in the solar corona. This finding, derived from observations of a significant solar flare in 2017, enhances our understanding of solar flare physics and could improve space weather forecasting.www.spacetimewithstuartgary.com✍️ Episode ReferencesJournal of the Proceedings of the National Academy of SciencesNature CommunicationsNature AstronomyBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.(00:00:00) Scientists studying Saturn's moon Titan have discovered that normally incompatible substances can mix(00:05:19) NASA will launch the Dragonfly mission to Titan in 2028(00:13:36) NASA's Europa Clipper spacecraft will study icy moon Europa(00:18:11) Astronomers have discovered that gamma rays generated by solar flares are caused by electrons(00:21:58) Most people who take diabetes drug Mounjaro gain weight back after stopping

The stars on the rim of the galaxy are going for a ride. They’re bobbing up and down like the horses on a merry-go-round. They’re also rippling outward, away from the center of the Milky Way. The Milky Way consists of a thin disk of stars and gas that spans a hundred thousand light-years or more. For decades, we’ve known that the rim of the disk is warped like the brim of a wide hat. It’s bent upward on one edge, and downward on the opposite edge. A recent study found that stars on those edges are moving along a big wave. Astronomers looked at the locations and motions of more than 20,000 bright young stars logged by the Gaia space telescope. The stars are as much as 45,000 light-years from the galactic center. Gaia found that the stars are bobbing up and down as much as a thousand light-years above or below the plane of the galaxy. And they appear to be sliding outward at thousands of miles per hour. The wave might have been created by a close approach of a smaller galaxy hundreds of millions of years ago. Its gravity disturbed the tranquility of the Milky Way’s outer precincts – sending the stars there for a ride. Under dark skies, the Milky Way is in good view tonight. In early evening, it extends along the body of Cygnus, the swan, in the west-northwest; through M-shaped Cassiopeia, higher in the sky; then down between Orion and the twins of Gemini, in the east-southeast.

Guest: Bob Zimmerman. A standard solar conjunction has caused a temporary communication blackout with Mars rovers, a routine event for which spacecraft are prepared. In other scientific developments, astronomers have detected the wake of a companion star moving through the atmosphere of Betelgeuse, while new archaeological evidence suggests Neanderthals possessed the technology to create fire 400,000 years ago, pushing back the known timeline for this capability significantly.1959

This year, comet 3I/Atlas broke into our solar system, but also the zeitgeist. This dirty snowball is a visitor from another solar system, and it's only the third interstellar object we've ever spotted. And today, it's closer to us than ever before—just 170 million miles away.Astronomy experts Stefanie Milam and Hakeem Oluseyi join Host Flora Lichtman to dish about 3I/ATLAS and how it captured the spotlight in a way that maybe no other big hunk of rock ever has.Plus, the sun is setting on the ISS, and the plan is to eventually crash it  into the ocean. But wouldn't it be cooler to send it into deep space instead? A listener pleads his case.Guests: Dr. Stefanie Milam is an astrochemist at NASA and a project scientist for the James Webb Space Telescope.

DISCOVERY OF GIANT RADIO GALAXIES AND SUPERMASSIVE BLACK HOLES Colleague Dr. Sabayashi Pal. Astronomers have discovered 53 giant radio galaxies, some 75 times larger than the Milky Way, powered by active supermassive black holes emitting radio jets. These ancient objects offer insights into galactic evolution, contrasting sharply with the Milky Way's smaller, dormant black hole that allows life to exist safely. NUMBER 13 1958

SHOW 12-18-25 THE SHOW BEGINS IN DOUBTS ABOUT THE POTUS AT YEAR'S END... 1951 BALD EAGLE ALASKA CRUNCH EU SUMMIT DISCUSSES USING FROZEN RUSSIAN ASSETS FOR UKRAINE Colleague Anatol Lieven. The European Union is internally divided over seizing frozen Russian assets to fund Ukraine's war effort and reconstruction, a move requiring rule changes that some members resist. While the US proposes using these funds for post-war rebuilding, current plans risk spending the capital on immediate warfare, potentially undermining international financial trust. NUMBER 1 NATO AND EU SEEK DEFENSE FUNDS AMID FEARS OF RUSSIAN AGGRESSION Colleague Anatol Lieven. European nations like Finland are demanding funds to counter perceived Russian threats, despite a lack of historical aggression toward them. Lieven argues that plans to spend billions on tanks are misguided, as the Ukraine war demonstrates that expensive armor is easily destroyed by cheaper drones and defensive lines. NUMBER 2 CALIFORNIA JOB LOSSES AND CHINA'S ECONOMIC SLOWDOWN AMID RETAIL SEASON Colleague Chris Riegel. California's new wage mandates have triggered significant job losses in the fast-food sector, forcing operators to move to lower-tax states. Internationally, while China boasts of leads in AI and EVs, these sectors rely on unsustainable subsidies, masking a deep consumer recession and deflation in the property market. NUMBER 3 SPAIN'S GOVERNMENT MAINTAINS TIES WITH VENEZUELA DESPITE OPPOSITION Colleague Mary Anastasia O'Grady. The Spanish government under Pedro Sanchez maintains ideological and economic alliances with the Maduro regime, prioritizing political agendas over democratic ideals. Opposition figure Cayetana Alvarez de Toledo accuses former Prime Minister Zapatero of acting as an international agent for Maduro, facilitating the dictatorship's survival despite mass migration. NUMBER 4 CHINA'S SURREPTITIOUS SUPPORT KEEPS THE MADURO REGIME AFLOAT Colleague Professor Evan Ellis. China sustains the Maduro regime through loans, surveillance technology, and military equipment while bypassing sanctions to import Venezuelan oil. The state oil company, PDVSA, collapsed due to the purging of technical experts and lack of investment, forcing Venezuela to rely on Iranian engineers to maintain minimal production. NUMBER 5 VENEZUELA'S TRAGIC DECLINE FROM PROSPERITY TO AUTHORITARIANISM Colleague Professor Evan Ellis. Historical imagery reveals Venezuela's transformation from a prosperous, modern nation in the 1950s to a ruined state today. Deep inequality and corruption in the pre-Chavez era alienated the poor, allowing Hugo Chavez to capitalize on their frustration and dismantle the free market system, leading to the current crisis. NUMBER 6 ELECTIONS IN CHILE, PERU, AND HONDURAS SIGNAL REGIONAL SHIFTS Colleague Professor Evan Ellis. In Chile, José Antonio Kast's rise reflects a rejection of progressive policies and crime, favoring order and investment. Meanwhile, Peru faces political fragmentation and violence, Honduras struggles with electoral disputes, and Costa Rica appears poised to elect a pro-US candidate who aims to limit Chinese influence. NUMBER 7 ARGENTINA'S CREDIT RATING RISES AS BRAZIL FACES POLITICAL POLARIZATION Colleague Professor Evan Ellis. S&P upgraded Argentina's credit rating following Javier Milei's austerity measures, which have stabilized the currency and reduced inflation despite social costs. In Brazil, the reduction of Jair Bolsonaro's prison sentence and his son Flavio's candidacy signal a continued, polarized struggle against Lula da Silva's agenda for the 2026 election. NUMBER 8 ROMAN KINGSHIP: FROM CITIZEN SELECTION TO THE IDEAL OF SERVICE Colleague Professor Edward J. Watts. Early Roman kings were selected by citizens based on merit rather than heredity, but figures like Servius Tullius began bypassing this consent. Conversely, Cincinnatus exemplifies the Roman ideal of service; he accepted absolute dictatorial power to save the state during a crisis, then immediately resigned to return to his farm. NUMBER 9 APPIUS CLAUDIUS CAECUS: INFRASTRUCTURE AND POLITICAL GENIUS Colleague Professor Edward J. Watts. Appius Claudius Caecus transformed the Roman censorship office into a power base by building the Appian Way and appointing wealthy Italians to the Senate. As a blind elder statesman, he shamed the Senate into rejecting peace with Pyrrhus, insisting Rome must fight to maintain its dominance and ancestral legacy. NUMBER 10 ROME VS. CARTHAGE: DESTINY, TRAGEDY, AND THE CONSENSUS FOR WAR Colleague Professor Edward J. Watts. The conflict between Rome and Carthage is symbolized by the tragedy of Dido, representing the incompatibility of their powers. Despite Hannibal's devastating victories, the Roman Republic prevailed through a political system that prioritized consensus and collective sacrifice, allowing them to endure immense losses without surrendering. NUMBER 11 THE GRACCHI BROTHERS AND THE RISE OF POLITICAL VIOLENCE IN ROME Colleague Professor Edward J. Watts. The Gracchi brothers introduced political violence to Rome, with Tiberius using populism to revive his career and Gaius acting as a true believer in reform. Their assassinations by the Senate marked a departure from peaceful republican norms, as the elite used violence to protect entrenched economic inequality. NUMBER 12 DISCOVERY OF GIANT RADIO GALAXIES AND SUPERMASSIVE BLACK HOLES Colleague Dr. Sabayashi Pal. Astronomers have discovered 53 giant radio galaxies, some 75 times larger than the Milky Way, powered by active supermassive black holes emitting radio jets. These ancient objects offer insights into galactic evolution, contrasting sharply with the Milky Way's smaller, dormant black hole that allows life to exist safely. NUMBER 13 INVESTING IN HUMAN INTELLECT OVER ARTIFICIAL INTELLIGENCE Colleague Dr. Sabayashi Pal. Given an unlimited budget, Dr. Pal would prioritize human resource development over new telescopes, proposing a space study institute in Africa to train experts. He argues that while AI is a useful tool, education is essential for humans to interpret data and appreciate the machinery rather than being replaced by it. NUMBER 14 EUROPE SCROUNGES FOR FUNDS AMID RUSSIAN ASSET DISPUTES Colleague Michael Bernstam. The UK threatens to seize proceeds from the sale of Chelsea FC for Ukraine aid, while the EU struggles to finance a $135 billion shortfall for Kyiv. European leaders propose leveraging frozen Russian assets for loans, but financial markets remain skeptical of the EU's ability to guarantee such debt. NUMBER 15 CONGRESSIONAL SPENDING AND THE REVERSE MIDAS TOUCH Colleagues Dave Hebert and Peter Earle. Hebert and Earle argue that Congressional spending exacerbates problems in education and healthcare by subsidizing demand while restricting supply through regulations. They contend politicians prefer "showy" supply-side interventions, like drug busts, over effective policies because the politics of appearing effective outweigh the economics of actual affordability. NUMBER 16
