Few artists in Australian rock can rival the mystique and creative longevity of Steve Kilbey, the visionary frontman, bassist, and chief songwriter for The Church. In this captivating and wide-ranging episode of A Breath of Fresh Air with Sandy Kaye, Steve joins Sandy for an honest, funny, and deeply revealing conversation about his extraordinary life in music — before, during, and long after The Church became global icons.Born in Welwyn Garden City, England, and raised in Canberra, Australia, Steve's story begins long before his name became synonymous with the band that gave us Under the Milky Way. He talks about his early fascination with sound — from his parents' record collection to the spark that led him to pick up a guitar. Before fame, there were years of small gigs, knock-backs, and sheer determination to make his art heard.In 1980, that persistence paid off. Steve co-founded The Church, alongside guitarist Peter Koppes, drummer Nick Ward, and later Marty Willson-Piper. Their unique blend of shimmering guitars, surreal lyrics, and atmospheric soundscapes quickly set them apart. Their debut single, The Unguarded Moment, catapulted them to prominence, and soon The Church became one of Australia's most distinctive exports — a band equally loved for its mystery as for its music.But it was 1988's Starfish that turned The Church into international stars. The haunting single Under the Milky Way became a global anthem, securing their place in rock history. In this episode, Steve tells the story behind that song — the serendipity of its creation, his initial doubts, and how it continues to define the band's legacy decades later.Steve also shares candid insights into the creative tensions and triumphs within The Church — what it's like to lead a band for more than forty years, to evolve through changing line-ups, and to stay inspired through it all. He discusses how albums like Priest=Aura and Hologram of Baal marked turning points in their sound, and how the band's most recent work, including The Hypnogogue, proves they're still pushing boundaries today.Beyond the band, Steve's story is one of relentless creativity. He's released more than 20 solo albums, collaborated with artists like Grant McLennan and Martin Kennedy, and built a reputation as a painter, poet, and author. His life is art in motion — a never-ending exploration of sound, colour, and language.Throughout the conversation, Sandy and Steve explore everything from fame and spirituality to songwriting, success, and the wisdom that comes with time. He reflects on how his creative process has evolved, the lessons he's learned from the highs and lows, and what keeps him making music with such passion after all these years.As always, Steve's dry humour, self-awareness, and poetic way of thinking shine through. This episode is more than an interview — it's an invitation into the inner world of a true artist, still searching, still experimenting, and still mesmerising audiences worldwide.If you've ever been moved by Under the Milky Way, fascinated by the evolution of Australian rock, or curious about what drives a lifelong creative soul, this is one you won't want to miss.

Send us a textStart with a world that looks arranged and ask the most honest question: who arranged it? We walk up the Areopagus with Paul, listen to his bold claim that God made “the world and all things in it,” and then follow that claim into modern labs, star fields, and the quiet intricacy of a single living cell. From the intuitive logic of Mount Rushmore to the stubborn math behind monkeys at typewriters, we weigh whether time and chance can truly write coherent sentences—much less encode the deep, layered information of DNA.Together we unpack why Paul began with origins when speaking to curious, skeptical minds. The term he chose—cosmos—means order and arrangement, and that word shapes how we read everything from gravitational harmony to biochemical choreography. Along the way, we hear how thinkers like Copernicus, Kepler, Newton, and even a late-life Anthony Flew saw purpose in the fabric of reality. We revisit Darwin's own cautions and explore why the discovery of information-rich systems in the cell complicates a purely unguided story of life. Far from shutting down science, this vision of creation energizes it—inviting us to seek laws because we trust the Lawgiver and to ask better questions because we expect real answers.All of this lands close to home. If a God wise enough to order galaxies also numbers our days, then trust is not blind; it's fitting. We talk frankly about the cultural costs of denying design—how meaning, morality, and hope begin to slip—and we point to a better foundation: Christ the Creator, the one who holds all things together and can steady our steps. If He keeps the planet spinning and the Milky Way in motion, He can guide a week, a decision, a life.

Arianespace Launch Delay: Arianespace has quietly postponed the inaugural flight of its powerful Orion 64 rocket to 2026, a significant shift from its initial late 2025 schedule. This delay impacts Amazon's Project Cooper satellite constellation, which aims to compete with SpaceX's Starlink, highlighting the challenges of securing reliable launch providers in the competitive space market.Mysterious Interstellar Object: The interstellar object 3I ATLAS is perplexing scientists by emitting nickel tetracarbonyl, a compound never before observed in nature. Unlike typical comets, this object is ejecting material towards the Sun, defying known cometary physics and raising questions about its origins, including the possibility of artificiality.Gamma Ray Glow Debate: Astronomers are revisiting the source of a puzzling gamma ray glow from the Milky Way's center. Recent simulations suggest that a clumpy distribution of dark matter could be responsible, reinforcing the theory that dark matter particles may annihilate and produce detectable gamma rays, adding complexity to the ongoing debate.Double Comet Viewing Opportunity: Stargazers can look forward to a rare sight as Comet LEMMON and Comet Swan approach Earth on October 20. Both comets will be visible with binoculars or small telescopes, and live streams of the event will be available for those unable to observe directly. https://www.virtualtelescope.eu/webtv/ https://www.youtube.com/@GianMasiVirtualTelescope/streamsBest Space Photography Resources: For breathtaking space photography, listeners are encouraged to explore official agency websites like NASA and the European Space Agency, as well as community platforms such as Reddit's r/Astrophotography and AstroDailyPod Bin, where amateur astrophotographers share their stunning work and contribute to citizen science projects.For more cosmic updates, visit our website at astronomydaily.io.

Step back onto the frozen soil of Hinterkaifeck, where a killer didn't just murder a family, he moved in. In Part 2, we rewind the scene one last time, then push deeper: the footsteps that came from the woods and never went back, the attic noises, the missing keys… and a methodical slaughter carried out in silence. We follow the town's favorite suspect, Lorenz Schlittenbauer, and then widen the circle. Karl Gabriel the “dead” husband, the Gump brothers, the Thalers, and the transatlantic boogeyman Paul Mueller. Autopsies in the barnyard, chores done by the killer, warm ashes in the hearth. This is the part where folklore swallows fact and the case refuses to die. Citizens of the Milky Way, prepare yourselves for The Shadow Over Hinterkaifeck: Part Two! 

Primordial Earth Discovery: Researchers have identified what may be the first physical traces of primordial Earth, dating back over 4.5 billion years, suggesting fragments of the planet's original materials still exist deep within the mantle. This groundbreaking study challenges previous assumptions about Earth's turbulent beginnings and the impact that formed the Moon.Dark Matter Interactions: New theoretical work proposes that dark matter might interact with normal matter through a subtle dark force, rather than solely through gravity. This concept could help explain anomalies in galaxy rotation curves and may require highly sensitive experiments to detect these weak interactions.Spotting the Andromeda Galaxy: The Andromeda Galaxy, our closest major galactic neighbor, is visible to the naked eye under dark skies. Listeners can learn how to locate it using the constellation Andromeda and the great square of Pegasus, and discover its significance as it approaches a future merger with the Milky Way.Green Fireball Meteor Over Tennessee: Residents in Tennessee witnessed a brilliant green fireball meteor, characterized by its striking emerald hue due to high concentrations of magnesium and nickel. This event offers scientists valuable insights into the composition of meteoroids and their interactions with Earth's atmosphere.Foldable Solar Sails for Space Travel: An innovative concept involving foldable solar sails for aerobraking and atmospheric reentry could revolutionize space travel. These sails would increase drag during atmospheric entry, reducing the need for propellant and allowing for more efficient missions.For more cosmic updates, visit our website at astronomydaily.io.

Kobo by Richard AllenKobo, a 14-year old boy, is the pampered pet of two grobs on the planet Pavin near the center of the Milky Way galaxy whose ancestors were brought to Pavin millennia before and domesticated as pets. Kobo, like other humans on Pavin, is raised largely in isolation from other humans and therefore without language or culture. Soon his grobs acquire a companion for Kobo, a 15-year old girl named Ra. The pair have two babies, both of whom are sold as toddlers to other grobs. When the second is sold, Kobo attacks the male grob with a knife, and he and Ra are separately transported to the planet Loma in the Pavin system where humans work as slaves in the mines. The story follows Kobo and Ra as they learn to communicate, work in the mines and discover a community of humans in hiding from the grobs.About the Author:Richard Allen is a lawyer who lives with his wife and their yellow and chocolate Labrador retrievers in Crested Butte, Colorado. A long-time fan, and former teacher, of science and speculative fiction, his love of pets led him to wonder what humans would be like in similar circumstances and to write this book. Allen's other interests include the law–he has argued ten cases in the Supreme Court and taught courses on the Constitution, the Supreme Court and criminal justice–as well as history, playing the guitar and harmonica while his dogs howls along. chess and most other games and outdoor sports of all kinds. This is his first published novel.AMAZONKOBO'S CHILDRENhttps://www.richardallenauthor.com/https://www.kingpagespress.com/

In this episode of SpaceTime, we explore groundbreaking discoveries that reshape our understanding of Mars, the Moon, and the Milky Way Galaxy.Ancient Oceans on Mars: Geological Evidence RevealedA new study published in the journal Geophysical Research Letters presents compelling geological evidence that Mars' Northern Hemisphere was once home to a vast ocean. Lead author Chris from the University of Arkansas discusses how comparisons between river rocks on Earth and Martian sediment reveal ancient river deltas and backwater zones, suggesting that liquid water flowed on the Red Planet, increasing the possibility of past life. This episode delves into the processes of sedimentation and erosion that shaped Mars' landscape, providing insights into its watery past.The Moon's South Pole-Aitken Basin: Unveiling Impact MysteriesA fresh analysis of the Moon's largest impact crater, the South Pole-Aitken Basin, sheds light on its formation and the Moon's geological history. Researchers have discovered that this massive crater's shape indicates an impact from the north, challenging previous assumptions. As the Artemis missions prepare to land near this basin, they will have the opportunity to study material excavated from the lunar interior, potentially unlocking secrets about the Moon's evolution and the asymmetries in its crust.Nancy Chris Roman Space Telescope: Mapping the Milky WayNASA's upcoming Nancy Chris Roman Space Telescope is set to revolutionise our understanding of the Milky Way's interstellar medium. This mission will map around 20 billion stars, using infrared light to penetrate the dust clouds obscuring our view. Chief investigator Catherine Zucker explains how this data will refine our models of star formation and the galaxy's structure, while also addressing the ongoing mysteries of galactic spiral patterns and their role in star birth.www.spacetimewithstuartgary.com✍️ Episode ReferencesGeophysical Research Lettershttps://agupubs.onlinelibrary.wiley.com/journal/19448007Naturehttps://www.nature.com/natureNASA Nancy Chris Roman Space Telescopehttps://roman.gsfc.nasa.gov/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.Ancient Oceans on Mars: Geological Evidence RevealedThe Moon's South Pole-Aitken Basin: Unveiling Impact MysteriesNancy Chris Roman Space Telescope: Mapping the Milky Way(00:00) Evidence of ancient oceans on Mars(10:15) New insights into the Moon's largest impact crater(19:30) The upcoming Nancy Chris Roman Space Telescope mission(27:00) Science Robert: Heatwaves and their impact on global mortality

Eighty percent of the world's population can't see the Milky Way. Light pollution interferes. Author and adventurer Craig Childs, of Norwood, Colorado, writes about a trek from light to dark in his new book. "The Wild Dark" takes readers from the incandescence of Las Vegas to the spangled skies of rural Nevada. Childs spoke with Sr. Host Ryan Warner at the Mountain Words Festival in Crested Butte in May. 

The Milky Way is a giant among galaxies – a hundred thousand light-years in diameter. But a few galaxies make the Milky Way look like a mere bauble by comparison. They span millions of light-years – puffed up by the action of supermassive black holes. These monsters are known as giant radio galaxies. Not only are they large, but they produce enormous amounts of radio waves. The black hole in such a galaxy’s heart is encircled by a massive disk. As material in the disk spirals into the black hole, magnetic fields fire “jets” of some of its particles like water from a firehose. These jets can streak far into space. They end as they plow into the material between galaxies, forming “lobes” that are bright sources of radio waves. A recent study found 15 of these giants. They’re in the constellation Sculptor, which creeps low across the south on October evenings. The largest of them spans more than 12 million light-years. The galaxy itself is wider and heavier than the Milky Way. But the jets puff up its overall size. It actually has two sets of jets – one nested inside the other. The longer set is older – powered up by the black hole millions of years ago. But the black hole might have slowed down its eating for a while, shutting off that flow of particles. Later, it started chowing down again, powering the second set of jets, which continue to expand – sustaining this galactic monster. Script by Damond Benningfield

There are more human cells in your body than there are stars in the Milky Way galaxy! Cells are the fundamental building blocks of life but that doesn't mean they are simple – biology still doesn't have a full picture of how exactly a living cell works. Host Regina G. Barber talks with bioengineers Kate Adamala and Drew Endy about why scientists are trying to build a cell from scratch, piece by piece. They dive into what it would look like to be inside of a cell, why scientists are bothering with making a cell from scratch and how engineers are leading the field.Want more bioengineering stories?

Deneb, the brightest star of Cygnus, stands high overhead as night falls at this time of year. And it really is a brilliant star – tens of thousands of times brighter than the Sun. But if we could tune our eyes to see radio waves, Deneb wouldn’t even register. Instead, the swan’s leading light would be Cygnus A – one of the brightest radio galaxies in the universe. A radio galaxy produces huge amounts of radio waves. It’s usually a large elliptical galaxy, which looks like a fat, fuzzy football. It has a supermassive black hole at its center. Gas, dust, and stars spiral into the black hole. But powerful magnetic fields eject some of that material back into space. It forms “jets” that fire out at almost the speed of light. The jets can span hundreds of thousands of light-years. Electrons spiral through a jet’s magnetic field, producing radio waves. Eventually, the jets plow into gas and dust between galaxies, forming wide bubbles that emit even more radio waves. Cygnus A was the first radio galaxy ever discovered, in 1939. It’s about 760 million light-years away. Its black hole is two and a half billion times the mass of the Sun. The entire complex – galaxy, jets, and bubbles – spans more than 600,000 light-years. That’s six times the diameter of our home galaxy, the Milky Way – one of the biggest, brightest radio galaxies in our part of the universe. More about radio galaxies tomorrow.

Remembering Jane Goodall with Primatologist Carson BlackIn this deeply heartfelt episode, David speaks with Primatologist, Biological Anthropologist, and Conservationist, Carson Black, who has spent her academic career studying chimpanzees in Senegal and howler monkeys in Costa Rica.Together, they reflect on the life and legacy of Jane Goodall, the “living Darwin of the modern era,” and how her groundbreaking work continues to shape the way we understand both chimpanzees and ourselves.Carson shares vivid stories from the field—bucket showers under the Milky Way, mischievous chimps throwing rocks, and the humbling power of seeing the world from their perspective. The two also discuss the history of primatology, the pioneering “Trimates” (Jane Goodall, Dian Fossey, and Biruté Galdikas), and the role of indigenous knowledge in modern science.This episode serves as both a tribute to Jane Goodall and a reminder that anthropology isn't just about the past—it's about the relationships that continue to define what it means to be human.Links:davidianhowe.comDavidianhowe.com/storeArchPodNetAPN Website: https://www.archpodnet.comAPN on Facebook: https://www.facebook.com/archpodnetAPN on Twitter: https://www.twitter.com/archpodnetAPN on Instagram: https://www.instagram.com/archpodnetAPN ShopAffiliatesMotion Hosted by Simplecast, an AdsWizz company.

Your brain weighs just three pounds, yet it's capable of storing 2.5 petabytes of information (around 3 million hours of high-def TV). It fires signals as fast as a Formula 1 car speeding at 268 miles per hour, and has roughly 100 billion neurons (as many as the stars in the Milky Way). Your brain generates about 20 watts of power - enough to light a dim bulb. But the most interesting part about this is that half of your powerful brain is devoted entirely to vision, processing images in as little as 13 milliseconds. That's 10x faster than the blink of an eye. In this episode, Josh sits down with Dr. Meenal Agarwal, board-certified optometrist, author and host of the Uncover Your Eyes podcast, to explore how the brain and eyes work together and what it takes to keep them healthy.   TOPICS DISCUSSED IN THIS EPISODE: How your eyes work and the eye-brain connection How screens are creating poor eyesight What's causing vision loss in our world today How to repair eyesight Eyesight prevention and protecton for yourself and your kids How poor eyesight create slow reactions times and puts you at risk The gut-eye-brain connection Amazing facts about your brain (and your eyes)   More from Dr. Meenal Agarwal Instagram: @dr.meenalagarwal Podcast: Uncover Your Eyes Website: drmeenal.com     Leave us a Review: https://www.reversablepod.com/review   Need help with your gut?

Nick Lane has some pretty wild ideas about the evolution of life.He thinks early life was continuous with the spontaneous chemistry of undersea hydrothermal vents.Nick's story may be wrong, but I find it remarkable that with just that starting point, you can explain so much about why life is the way that it is — the things you're supposed to just take as givens in biology class:* Why are there two sexes? Why sex at all?* Why are bacteria so simple despite being around for 4 billion years? Why is there so much shared structure between all eukaryotic cells despite the enormous morphological variety between animals, plants, fungi, and protists?* Why did the endosymbiosis event that led to eukaryotes happen only once, and in the particular way that it did?* Why is all life powered by proton gradients? Why does all life on Earth share not only the Krebs Cycle, but even the intermediate molecules like Acetyl-CoA?His theory implies that early life is almost chemically inevitable (potentially blooming on hundreds of millions of planets in the Milky Way alone), and that the real bottleneck is the complex eukaryotic cell.Watch on YouTube; listen on Apple Podcasts or Spotify.Sponsors* Gemini in Sheets lets you turn messy text into structured data.

Looking at the stars on a clear dark night, far from the artificial air glow humanity creates, have you ever wondered what it would be like to travel in truly deep interstellar space? 40 years after their launches in 1977, your representatives, the twin Voyager 1 and Voyager 2 spacecraft are in the vast space between the stars in our Milky Way galaxy. Aboard each Voyager is a Golden Record time capsule which expected to last billions of years. This message from all of humanity is inscribed with greetings from Earth as well as sounds, images, and a decoding key which will enable any intelligent aliens which find a Voyager to discover who made it and where it came from.

In this episode of SpaceTime, we explore the future of our universe, the latest advancements in mapping our Milky Way, and the pivotal role fungi played in the evolution of life on land.The Universe's Fate: A Big Crunch in 20 Billion YearsA groundbreaking study published in the Journal of Cosmology and Astroparticle Physics reveals that the universe is approaching the midpoint of its 33 billion-year lifespan and may end in approximately 20 billion years. Lead author Henry Tighe from Cornell University presents new data suggesting that the universe's cosmological constant may be negative, leading to a contraction and eventual collapse—a phenomenon referred to as the "big crunch." This research, based on observations from the Dark Energy Survey and the dark energy spectroscopic instrument DESI, challenges long-held beliefs about the universe's eternal expansion and opens new avenues for understanding cosmic evolution.Mapping the Milky Way: Gaia's 3D ViewThe European Space Agency's Gaia Space Telescope has unveiled the most precise three-dimensional map of star-forming regions within our Milky Way galaxy. By analysing data from 44 million stars, Gaia has provided insights into the obscured molecular clouds where new stars are born. This innovative mapping technique allows astronomers to understand the distribution of ionised gas and the dynamics of star formation, offering a fresh perspective on our galaxy's structure and the processes that shape it.Fungi: The Pioneers of Terrestrial LifeA recent study published in Nature Ecology and Evolution has identified that fungi played a crucial role in preparing Earth for life on land between 900 million and 1.4 billion years ago—much earlier than previously thought. Researchers from the Okinawa Institute of Science and Technology utilised a novel gene swap method to trace the evolution of fungi, suggesting that these organisms were instrumental in creating the first ecosystems and nutrient recycling processes that facilitated the emergence of terrestrial life. This discovery reframes our understanding of the timeline for life on Earth and highlights the importance of fungi in shaping our planet's biosphere.www.spacetimewithstuartgary.com✍️ Episode ReferencesJournal of Cosmology and Astroparticle Physicshttps://www.cosmos.esa.int/web/gaiaNature Ecology and Evolutionhttps://www.nature.com/neweBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.The Universe's Fate: A Big Crunch in 20 Billion YearsMapping the Milky Way: Gaia's 3D ViewFungi: The Pioneers of Terrestrial Life

Spring in Bavaria — soft hills, quiet cows, the sleepy days of a farm world nobody ever writes about. But Hinterkaifeck was already rotten to the roots long before the first skull cracked open in the hay. Foul rumors, missing keys, footsteps in the attic, shadows in the woods — the whole place felt like a bad dream pretending to be normal life. Then, one cold night in 1922, somebody lured the Gruber family out one by one, killed them with farm tools, and stayed. Slept in their beds. Fed the cows. Kept the fire burning while six bodies cooled a few feet away. Part one drags you back to that doomed little farm, through gossip thick as mud, neighbors who looked the other way, and a crime scene so disturbing its still discussed over a century later. This isn't just murder — It's the kind of story that crawls under your skin and never leaves.

Hotel Mars, Weds, Oct. 1, 2025 with Joel on Little Red Dots and JWSTOur guest for this Hotel Mars program was Dr. Joel Leja, a cosmologist at Penn State University. Dr. Leja discussed the discovery of mysterious red dots observed in the first images from the James Webb Space Telescope. These dots, initially thought to be tiny galaxies or massive structures, presented a puzzle as they were brighter and redder than expected, challenging existing cosmological models. Despite the initial surprise, further data analysis revealed that these objects were likely extremely compact systems, much smaller than the Milky Way, which Joel and his team are still working to understand fully.The three of us discussed the James Webb Space Telescope's discovery of distant objects, estimating their existence around 11.9 billion years ago, with some as early as 5.7 billion years. Dr. Leja noted that these objects primarily exist in the early universe, with one rare exception in the nearby universe. The discussion focused on the mystery of these objects' existence, given the limited time available for their formation, and the need to determine their nature and origin.Joel also discussed the discovery of bright objects in the early universe, initially thought to be galaxies but later identified as supermassive black holes due to the presence of hot swirling gas. Despite this explanation, several mysteries remain, including how these massive black holes formed so quickly and their unusual lack of expected features like glowing cosmic dust. Joel noted that while the black hole hypothesis is the leading explanation, numerous other theories exist, making it an exciting time in astrophysics.Our guest discussed the concept of “little red dots” in the early universe, which may be supermassive black holes surrounded by dense gas, resembling stars. John, in the last segment of the program, asked what he would do with an unlimited budget. Our guest explained that this hypothesis, known as the black hole star hypothesis, is the only one that currently aligns with observed data. Joel expressed interest in exploring this idea further, potentially with an enhanced version of the James Webb Space Telescope, to understand the formation and properties of the first stars in the universe. He also mentioned using the unlimited budget to build many more JWST's.Special thanks to our sponsors:Northrup Grumman, American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentOur Toll Free Line for Live Broadcasts: 1-866-687-7223For real time program participation, email Dr. Space at: drspace@thespaceshow.comThe Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From May 2025. Today's 2 topics: - On May 5, 2014 when I discovered 2014 JO25 with the Catalina Sky Survey's 60 inch telescope on Mt. Lemmon, Arizona it was the brightest, fastest asteroid I had ever seen. In April of 2017, 2014 JO25 returned to come within 1.1 million miles of us at 21 mi/s. This rare, very close approach by an asteroid, of 2014 JO25's size allowed scientists at NASA's Goldstone Solar System Radar in California and the National Science Foundation's Arecibo Observatory in Puerto Rico to obtain radar images of it.    - The NASA Kepler Spacecraft has discovered more than 2,000 planets which have been confirmed to be orbiting distant stars. It performs this remarkable feat by imaging more than 145,000 stars simultaneously to observe and measure the tiny dips in light which occur as a planet passes in front of its star. Astronomers have long known that many of the solar systems in the Milky Way have more than one star.    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!

The Andromeda Galaxy, M31, is encircled by dozens of satellites – smaller galaxies in orbit around it. One of the larger satellites is something of an oddball. Of the three-dozen brightest, it’s the only one that lines up on the far side of Andromeda as seen from our home galaxy, the Milky Way. M31 is the closest giant galaxy to the Milky Way – just two-and-a-half million light-years away. Messier 110 is a couple of hundred thousand light-years farther. It’s a few thousand light-years in diameter, and contains about 10 billion stars – a tiny fraction the size of Andromeda. Astronomers have spent years watching M31’s entourage with Hubble Space Telescope. They recently reported that 36 of the 37 brightest members line up on the side of M31 that faces the Milky Way. And that’s hard to explain. The study said there’s only a tiny chance that the alignment is a coincidence – there must be a reason for it. But no one knows what that reason might be. It’s not a result of the Milky Way’s gravitational pull – it’s not strong enough. So there’s no obvious explanation for why M110 is an oddball – lurking on the far side of M31. M31 is low in the northeast at nightfall. Under dark skies, it looks like a hazy slash of light about as wide as the Moon. Through a small telescope, M110 looks like a bright star close by.

The closest giant galaxy to the Milky Way is Messier 31, the Andromeda Galaxy. It’s two-and-a-half million light-years away. But it’s getting closer – by about 250,000 miles every hour. For more than a decade, in fact, it’s looked like the two galaxies were on a collision course. But a recent study says there’s only a 50-50 chance of a collision and merger. And if it does happen, it’ll take place billions of years later than previous estimates. The new study used years of observations by two space telescopes – Hubble and Gaia. Researchers plugged those observations into simulations that also considered the gravitational effects of two smaller galaxies. The results indicated that one of them tends to push Andromeda and the Milky Way together, while the other tends to pull them apart. The researchers ran a hundred thousand simulations. In half of them, Andromeda and the Milky Way flew past each other and went their own ways. In the other half, they eventually spiraled together and merged – but not for at least 10 billion years – twice as long as earlier estimates. The simulations aren’t the final word – there are just too many uncertainties. But for now, it seems likely that the two giants will stay apart for a long, long time. M31 is in the northeast at nightfall. Under dark skies, it’s visible as a hazy patch of light. Binoculars make it easier to pick out. Script by Damond Benningfield

Messier 31, the Andromeda Galaxy, is the largest and most-distant object that’s easily visible to the unaided eye. Under dark skies, it looks like a skinny cloud about as wide as the Moon. Right now, it’s about a third of the way up in the northeast at nightfall. M31 is two-and-a-half million light-years away. In other words, the light you see from the galaxy tonight began its journey across the cosmos two-and-a-half million years ago. The galaxy is roughly 150,000 light-years across – bigger than the Milky Way – and may contain a trillion stars. It’s also the hub of its own galactic empire – it’s orbited by more than three dozen smaller galaxies. And a recent study revealed many new details about the satellites. Astronomers spent years looking at them with Hubble Space Telescope. And they supplemented the new observations by going through older ones. They found that most of the stars in the smaller galaxies had been born by about 12 billion years ago – when the universe was about one-tenth of its present age. And star formation had all but stopped by about eight billion years ago. Galaxies that are bigger and farther from M31 gave birth to stars a little longer than those that are small and close. One of the bigger satellites might have rammed through M31 a few million years ago. That stirred things up throughout the empire surrounding big, beautiful M31. More about M31 tomorrow.

In this episode of SpaceTime, we explore the thrilling prospects of observing exploding black holes, an astonishing stellar jet on the outskirts of the Milky Way, and the meticulous preparations for an Earth observation satellite mission.Exploding Black Holes on the HorizonA groundbreaking study suggests that astronomers may soon witness a black hole explosion, an event theorised to occur once every 100,000 years. Researchers now believe there's a 90% chance of observing such an explosion within the next decade, potentially revealing primordial black holes formed shortly after the Big Bang. These explosions could provide a comprehensive catalogue of all subatomic particles, including those yet to be discovered, fundamentally altering our understanding of the universe's origins.Immense Stellar Jet DiscoveredAstronomers have identified a colossal stellar jet erupting from a young star in the Milky Way's outskirts, specifically in the Sharpless 2284 region. This rare phenomenon involves twin jets of hot plasma extending over eight light years, driven by superheated gases falling onto the massive star. Captured by NASA's Webb Space Telescope, this discovery not only sheds light on star formation but also offers insights into the conditions of the early universe.Preparing for Earth ObservationThe European Space Agency is conducting rigorous tests for a future Earth observation satellite mission, including an airborne campaign in the Arctic. Scientists are evaluating a new imaging microwave radiometer designed to monitor sea ice and its evolution. This mission aims to gather vital data on climate change and the Arctic environment, contributing to a better understanding of global phenomena.www.spacetimewithstuartgary.com✍️ Episode ReferencesPhysical Review Lettershttps://journals.aps.org/prl/NASAhttps://www.nasa.gov/European Space Agencyhttps://www.esa.int/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.Exploding Black Holes on the HorizonImmense Stellar Jet DiscoveredPreparing for Earth Observation

The Elephant in the Universe: 100-year search for dark matter Author: Govert Schilling The Century-Old Mystery Begins: Early Astronomical Observations Headline: Pioneers Uncover Unseen Gravitational Effects in the Cosmos In 1922, Jacobus Cornelius Kapteyn, a Dutch astronomer, was the first to introduce the term "dark matter" in a paper theorizing the arrangement and motion of the sidereal system, realizing unseen matter had gravitational effects within the Milky Way. A decade later, his student, Jan Oort, further identified the Milky Way's rotation and, by studying the up-and-down motions of stars, made an early estimate of dark matter in the galaxy's central plane. Building on this, Swiss astronomer Fritz Zwicky observed the Coma Cluster in California, using redshift to determine galaxy motions. He concluded there was more mass and gravity than visible, coining the German term "dunkle Materie," meaning "dark matter." These early 20th-century findings laid the groundwork for the ongoing dark matter mystery. 1957

The Elephant in the Universe: 100-year search for dark matter Author: Govert Schilling Theoretical Stability and Observational Proof of Dark Matter Halos Headline: Galaxies Need Invisible Halos: Ostriker and Rubin Provide Evidence In the late 1960s, theorist Jeremiah Ostriker calculated that a flattened galaxy like the Milky Way could not remain stable without a large, spherical "halo" of unseen matter surrounding it, providing a theoretical basis for dark matter. This theoretical need was then powerfully confirmed by the observational work of American astronomer Vera Rubin and her colleague Kent Ford throughout the 1970s. Studying distant galaxies, including Andromeda, they discovered that stars on the outer edges rotated at unexpectedly high, constant velocities, rather than slowing down as predicted. This "flattening the curve" of rotational velocities offered the first concrete proof for the existence of dark matter, whose gravity was necessary to prevent galaxies from flying apart. 1958
