Space Nuts: Moon impact, Roman Observatory launch, and Neptune's odd moonsAndrew Dunkley is joined by Professor Jonti Horner, Professor of Astrophysics at the University of Southern Queensland, for a wide-ranging astronomy update. They cover SpaceX's out-of-control rocket body hitting the Moon, the imminent launch of the Nancy Grace Roman Observatory, and a new result that may explain the strange origin of some of Neptune's moons.We discuss why lunar impacts matter far beyond the Moon itself, how Roman will study exoplanets and dark energy, and why clay minerals on Neptune's small moons are such a big clue about a violent early solar system.Key topicsSpaceX's rocket body impacted the Moon after being left in a long, uncontrolled orbitWhy lunar impacts are a real concern for future habitats, infrastructure, and Apollo heritage sitesThe sheer scale of human-made objects that have already hit or landed on the MoonElon Musk's vision for lunar factories, rail-gun launches, and large-scale off-Earth manufacturingWhy the same company could end up both creating the risk and needing to solve itThe Nancy Grace Roman Observatory launching around 9 months ahead of scheduleRoman's 2.4 metre mirror, 300 megapixel wide-field camera, and hydrazine-fueled journey to L2How Roman will study dark energy, gravitational lensing, exoplanets, and free-floating planetsNew James Webb observations of Neptune's moons showing clay-type minerals on Larissa and GalateaWhy those clays suggest a much older, more violent system shaped by Triton's capture and moon-to-moon collisionsTimestamps:00:00 - Studio prep, muting phones, and getting ready to record01:53 - Episode intro: SpaceX lunar impact, Roman Observatory, and Neptune moons03:00 - Jonti Horner joins the show04:26 - SpaceX rocket body crashes into the Moon07:03 - Predicted impact plume and expected crater size08:54 - Korean spacecraft Danuri captures post-impact images10:19 - Why Moon impacts matter for future lunar bases11:47 - Protecting Apollo landing sites and lunar archaeology12:15 - More than 3,000 human-made objects have hit the Moon14:32 - Law, responsibility, and the problem of cleanup beyond Earth16:07 - Musk's plans for Moon factories and Starlink-style expansion18:12 - Rail guns, Optimus robots, and scaling lunar industry19:34 - SpaceX's own industry could be threatened by its own debris21:24 - Balancing commercial benefits and environmental costs23:46 - The Nancy Grace Roman Observatory launch approaches26:03 - Roman's orbit, hydrazine fuel, and five-year mission plan27:57 - From WFIRST to Roman: how the telescope evolved29:23 - Roman's mirror, 300 megapixel camera, and survey power30:14 - Exoplanets, microlensing, and the coronagraph33:29 - Roman's launch status and the excitement ahead34:17 - Neptune's moons and the role of TritonBecome a supporter of this podcast: https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support.

After decades of development, the Nancy Grace Roman Space Telescope is preparing to launch. Once in orbit, Roman will conduct the widest surveys of the universe ever attempted, probing the nature of dark energy, discovering thousands of new exoplanets, and capturing images of billions of galaxies. In this episode, we sit down with Julie McEnery, senior project scientist for Roman at NASA's Goddard Space Flight Center, and Jason Rhodes, project scientist for Roman at NASA’s Jet Propulsion Laboratory, to explore what the telescope will reveal and how scientists around the world will be able to access and work with its data. Plus, in What's Up, we look at Roman's coronagraph and what it will take for the Habitable Worlds Observatory to push that technology far enough to image Earth-like worlds around Sun-like stars.

The first explores how astronomy keeps blurring the lines between asteroids and comets, what new research says about the dinosaur-killing impact, and a surprising crater found by an amateur astronomer planning a trip. The second is a listener Q&A covering exotic exoplanet weather, space regulation, and whether planets can form without a star.Key topicsIn this episode, Andrew and Jonti explain why astronomy often uses tidy labels for objects that sit on a continuum, especially when the line between asteroid and comet gets blurry.They discuss near-Earth object 1998 SH2, which appears to have comet-like activity despite looking asteroid-like for decades.Jonti breaks down how outgassing can nudge a small body off its predicted path, revealing non-gravitational forces.The dinosaur-killing impact is revisited with new modelling suggesting the first hours after impact may have included global firestorms, not just long-term climate collapse.The show covers the terminology debate around meteor, meteorite, fireball, bolide, asteroid, and comet impact.A Canadian amateur astronomer, Joel LePointe, is credited with spotting a likely impact crater while planning a camping and hiking trip using satellite imagery.The newly identified crater near Lake Marcel in northern Quebec is described as about 390 million years old and roughly 25 kilometers wide.Become a supporter of this podcast: https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support.

In this week's summertime rerun, Dr. James Emery White and co-host Alexis Drye discuss the fact that as culture becomes less and less rooted in Christianity, and people (sadly) have more and more encounters with Christians who are not very Christlike, misconceptions and caricatures of the Christian faith seem to be growing. Today's discussion, which was a listener-submitted topic, will walk through four of the most common caricatures in today's culture. Episode Links Here are some series given by Dr. White at Mecklenburg Community Church related to the caricatures covered in today's discussion that you may be interested in taking a look at: “The Science of God” “Astrophysics… for People Who Are Open to God” “Don't Check Your Brains at the Door” “When God Makes Us Laugh” “Why?” And then here are a few past podcast episodes that you can go back and listen to in case you missed them that may add to today's discussion: CCP103: On the Sudden Rise of LGBTQ CCP92: On Challenges to Believing the Bible CCP63: On Why Christians Are So Mean CCP49: On Faith vs. Science Finally, Dr. White mentioned a book that he wrote in the conversation today that you may want to check out: A Mind for God. It should also be noted here that he discussed a book by author Philip Yancey. Following the news that broke about Yancey's shadow life, we released another podcast episode you may want to go back and listen to: CCP179: On When a Beloved Leader Falls.

In this week's summertime rerun, Dr. James Emery White and co-host Alexis Drye discuss a congressional hearing on the subject of UAPs - Unidentified Aerial Phenomenon - more commonly known as UFOs. There has been a surge in sightings of UFOs, causing the government to take the issue more seriously. So is there really a place in a Christian worldview for belief in life on other planets? We thought it worthwhile to revisit this early podcast episode. Episode Links Dr. White wrote a blog on this subject called “UFOs… Confirmed?” that explores the significance of what it would mean for life on other planets to be confirmed. During the podcast, they also mentioned a book series called The Space Trilogy written by C.S. Lewis that you can find HERE on Amazon. Finally, it may also be helpful to listen to a series Dr. White delivered at Mecklenburg Community Church called “Astrophysics… for People Who Are Open to God.” It explores our fascination with cosmic things, and whether they point away from God or toward Him.

Astrophysics sheds a unique perspective on the universe and our place in it. On this episode, Dr. Neil deGrasse Tyson discussed his book, Letters from Astrophysicist. From an episode originally aired on 12-19-2019.

"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 book "Islands in Infinity: Galaxies 3-D," they turn flat images of the galaxies to three dimensional spacescapes that leap off the page. In March, Host Flora Lichtman spoke 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.

Scott Dodelson spent ten years on the Dark Energy Survey testing the standard model of cosmology. It passed and missed by 2.5 sigma. The Director of Fermilab's Cosmic Physics Division on why the theory he helped build may be wrong, why nobody can find dark matter, and what it takes to change a scientific consensus. Subscribe if you want science with evidence, not speculation. Dodelson is Director of the Cosmic Physics Division at Fermilab, Professor of Astronomy and Astrophysics at the University of Chicago, and author of Modern Cosmology, the textbook a generation of cosmologists learned the field from. Lambda-CDM predicts how the early universe's tiny fluctuations grew into the structure we see today. The Dark Energy Survey was designed to check that prediction. The answer came back two and a half sigma off. That is both the most precise measurement ever made of how the universe grew, and a crack he cannot stop looking at. His question is not whether the model is close. It is whether close is enough to trust. We get into the Sigma-8 tension and what it actually takes for a scientific community to change its mind, the Dodelson-Widrow mechanism and his 1994 proposal that sterile neutrinos produced in the early universe could constitute dark matter, and the Neptune vs. Vulcan history of getting dark matter right and wrong. Asked which of those two situations we are in now, Dodelson's answer is: I have no idea.

Scientists have discovered when one plant or animal faces extinction, the whole ecosystem is threatened. Michael Robinson with the Center for Biological Diversity talks about protecting the Mexican gray wolf in southern Arizona, and how it is crucial to wildlife patterns across the region. Michael Robinson spoke with Erika Hamden, Astrophysics professor at the University of Arizona.

Astronomy Daily · S05E153 · Wednesday 29 July 2026. Four stories from the frontier of space and astronomy, plus a both-hemispheres look at the sky — and news of our brand-new website. In this episode •  Betelgeuse is not alone. ESO's VLT/SPHERE has captured the clearest direct image yet of Betelgeuse B, the long-suspected companion to the famous red supergiant — ending a roughly century-long search. Published 28 July 2026 in Astronomy & Astrophysics (Montargès, Boccaletti et al.). The companion is more massive than predicted (≈2–3 solar masses), likely paces Betelgeuse's ~6-year brightness cycle, and may eventually spiral into the supergiant. •  Swift catches a wandering black hole. TDE 2025abcr — the most off-centre tidal disruption event ever seen — reveals a ~1-million-solar-mass “wandering” black hole ~30,000 light-years from its galaxy's core, ~750 million light-years away. First flagged by the Zwicky Transient Facility (Nov 2025) and pinned down with NASA's Swift; an AI sifted ~500,000 nightly flashes to find it. Published 27 July 2026 in The Astrophysical Journal Letters (Stein et al.; Carney et al.). •  Roman is fuelled for launch. NASA's Nancy Grace Roman Space Telescope completed fuelling on 25 July (≈290 gallons of hydrazine) and holds its mission-preview briefing today — one month from a 30 August launch, roughly eight months ahead of schedule. Roman will survey ~50× as much sky as Hubble in five years, probe dark energy, and is expected to find 100,000+ exoplanets via microlensing. •  Swift's rescue mission is in trouble. Katalyst's LINK servicing spacecraft — launched 3 July to boost the decaying Swift observatory — began spinning over the weekend; two of three reaction wheels are non-operable, with some cold-gas thruster degradation. LINK remains powered and in contact; the team is using its electric (xenon) thrusters to arrest the spin before deciding, with NASA, whether to proceed. Developing story — details accurate as of recording. •  Skywatch. Full Buck Moon tonight (29 July); Jupiter at solar conjunction; Southern Delta Aquariids favour the Southern Hemisphere but are washed out by the Moon this year; Alpha Capricornid fireballs are the pick for both hemispheres; the Perseids peak on the moonless night of 12–13 August alongside a total solar eclipse (Greenland/Iceland/Spain; partial for parts of Europe and North America). Never view the partial phases without ISO 12312-2 eclipse glasses. Sources •  ESO release eso2611 & Astronomy & Astrophysics, Montargès, Boccaletti et al., “VLT/SPHERE imaging of the candidate companion of Betelgeuse” (28 Jul 2026). •  NASA Swift / The Astrophysical Journal Letters — TDE 2025abcr wandering-black-hole discovery (27 Jul 2026); UNC-Chapel Hill release. •  NASA — Nancy Grace Roman Space Telescope fuelling & launch-preview updates (25–29 Jul 2026). •  NASA Swift blog — “Commissioning Update for Spacecraft to Boost NASA's Swift” (28 Jul 2026); Katalyst Space Technologies. •  EarthSky, NASA, American Meteor Society, timeanddate — meteor showers, Buck Moon, Jupiter conjunction, 12 Aug eclipse.

In this week's summertime rerun, Dr. James Emery White and co-host Alexis Drye discuss a topic that was sparked by a series given by Dr. White at Mecklenburg Community Church called “Primordial: Genesis and the World's Primeval History.” The culture of our day seems to want to place science and faith at odds with each other when in reality everything in science compliments God's existence - in fact, it demands it. What's ironic is that the study of science itself was deeply rooted in a Christian worldview. Episode Links In addition to the aforementioned series at Meck, there are two other series that Dr. White led on this topic that would be very helpful to check out. The first is called “The Science of God” with installments that explore the science of God's existence, of God's creation and of faith. The second is “Astrophysics… for people who are open to God.” As a culture, we seem to be almost obsessed with cosmic headlines from the Big Bang to black holes, from quarks to quantum mechanics, and from the search for planets to the search for life in the universe. This series explores whether when you delve into such things, they point away from God or to Him? Dr. White has also written blogs tied to today's conversation that we would encourage you to read. “A Post-Empirical God” discusses the concept of reductive naturalism and how scientists have become increasingly hostile towards religion. “From How to Who” is a blog that discusses the Scopes Trial you heard mentioned in today's episode. It points to the fact that the real issue of our day is not between creation and evolution, but rather between theism and naturalism. Finally, he wrote a blog titled “UFOs… Confirmed?” taking a look at the significance of life on other planets and how future discoveries in science may impact our faith. Dr. White's book Christianity for People Who Aren't Christians: Uncommon Answers to Common Questions is a great resource for you or others you may know who are open to exploring the Christian faith. He takes on the topic of faith vs. science in this book as well. You can find it HERE on Amazon or from your favorite bookseller. For those of you who are new to Church & Culture, we'd love to invite you to subscribe (for free of course) to the twice-weekly Church & Culture blog and check out the Daily Headline News - a collection of headlines from around the globe each weekday. We'd also love to hear from you if there is a topic that you'd like to see discussed on the Church & Culture Podcast in an upcoming episode.You can submit your questions through the form on the podcast website HERE.

Scientists have discovered certain plants get a head start on survival in drought conditions. University of Arizona researcher Alexander Bucksch discusses how some root systems use tiny hooks that bring in water and keep plants alive. Alexander Bucksch spoke with Erika Hamden, Astrophysics professor at the University of Arizona.

Can science and spirituality coexist? Is it possible to believe in both God and the scientific method without compromising either? Join Bernard Haisch, an internationally respected astrophysicist, author, and former researcher with NASA, as he explores these profound questions in a thoughtful discussion inspired by his book, The Purpose-Guided Universe. Drawing on decades of experience in astrophysics and cosmology, Dr. Haisch examines the relationship between modern science, consciousness, and humanity's search for meaning. He discusses how discoveries about the universe have prompted some scientists and philosophers to consider whether the cosmos may possess an underlying order or purpose, while encouraging listeners to think critically about the intersection of scientific inquiry and spiritual belief. Whether you're fascinated by astronomy, philosophy, theology, or the enduring question of why we exist, this compelling conversation offers fresh perspectives on one of humanity's oldest debates. Dr. Haisch invites listeners to explore the possibility that science and faith need not be opposing forces, but may instead provide complementary paths toward understanding ourselves, our universe, and our place within it.Become a supporter of this podcast: https://www.spreaker.com/podcast/the-x-zone-radio-tv-show--1078348/support.Please note that all CANCOM/XZBN radio and/or television shows are Copyright © REL-MAR McConnell Meda Company, Niagara, Ontario, Canada – www.rel-mar.com.

GJ 3378b — Revised Habitable-Zone Super-Earth, 25 Light-Years Away •    UC Irvine team revised the planet's mass down to 2.3 Earth masses (rocky super-Earth, not mini-Neptune) and orbital period to 21.45 days. •    Receives ~90% of the stellar radiation Earth receives from the Sun — squarely in the habitable zone. •    Atmosphere unknown; planet does not transit, so JWST transit spectroscopy isn't possible. Published in The Astrophysical Journal, led by Paul Robertson (UC Irvine). 5. ESO Study: 1.7 Million Planned Satellites 'Devastating' for Astronomy •    Study led by ESO astronomer Olivier Hainaut, accepted for publication in Astronomy & Astrophysics. •    Modelled impact of proposed constellations (SpaceX ~1M for space data centres, Reflect Orbital 50,000 mirror satellites) on ESO's VLT and the Vera Rubin Observatory. •    Recommends a hard cap of 100,000 satellites, all fainter than naked-eye visibility. Decision pending from the US FCC. 6. JWST Solves the WD 1856b Mystery •    Gas giant (4–11 Jupiter masses) orbits a white dwarf every 34 hours, blocking 56% of its star's light during transit. •    New JWST atmospheric data shows the planet is ~240K hotter than expected — evidence it migrated inward 3–5.5 billion years after the star's death, rather than surviving the red giant phase in place. •    Published July 1, 2026 in Nature, led by Ryan MacDonald with Northwestern's Christopher O'Connor.Become a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-the-latest-space-news--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

The Theory of Relativity was discovered by Einstein over a century ago, and it tells us how time and space are distorted when moving close to the speed of light. We mere earthlings don't get the opportunity to move that fast, but there are some phenomena in astrophysics that move very fast; more than 99.9999% of the speed of light. Ranadeep Dastidar is a computational modeler who writes code to predict and interpret these "relativistic" phenomena.

Durante más de medio siglo, Terzan 5 fue considerado un cúmulo globular más de la Vía Láctea. Sin embargo, nuevas observaciones publicadas en Astronomy & Astrophysics, cambia la forma en que los astrónomos interpretan uno de los objetos más estudiados del centro galáctico. Las nuevas observaciones realizadas con telescopios espaciales llamados James Webb y Hubble, han revelado que no se trata de un cúmulo estelar convencional, sino de un "fragmento fósil" del bulbo galáctico: un vestigio casi intacto de las primeras etapas de formación de nuestra galaxia. La investigación ha identificado cuatro generaciones distintas de estrellas, formadas a lo largo de unos 10.000 millones de años, algo incompatible con la naturaleza de un cúmulo globular clásico. Este descubrimiento convierte a Terzan 5 en una pieza clave para reconstruir cómo se creó la Vía Láctea y abre la puerta a que otros objetos sean fósiles cósmicos que han permanecido ocultos en el Universo.

By one of the world's leading chemists, an entertaining and revealing tour of the chemical bonds that shape our everyday lives and provide the infrastructure for our chaotic world.  We all have a relationship with chemistry. Bonds between molecules, forged and broken in the blink of an eye, underpin everything from the food we eat and the clothes we wear to the ways we treat illnesses and construct our homes. It's a relationship we nurture, whether we know it or not, and for leading chemist Ijeoma Uchegbu, it was serious from the beginning. In Chain Reaction: How Chemistry Shapes Us and Our World (HarperCollins, 2026) Uchegbu shows us the world through a chemist's eyes, revealing the intricate science we take for granted: how our body's most fundamental chemical structure, our DNA, is estimated to be two meters long, resting tightly within each of our cells; how egg yolks are held together by weak chemical bonds that make them primed for emulsifying our salad dressings; and how the chemical makeup of PFAs, or “forever chemicals,” makes them so good at sticking around. Along the way, we travel from Uchegbu's home in London to Nigeria, where cooking experiments go awry in her family kitchen, and to Italy, where the chemically inert compounds that make up stained glass keep medieval windows shining. The careful interplay of bonds and molecules brings a sense of order and wonder to the chaos of our lives, she shows, and we don't have to wear a lab coat or study solutions in beakers to appreciate it. For readers of Astrophysics for People in a Hurry and anyone who wanted to be like Elizabeth Zott in Lessons in Chemistry, Chain Reaction is a lively and intimate portrait of the wondrous and under-explored field that shapes our everyday lives.

Hiranya Peiris is playing a starring role in a movie that promises to tell perhaps the greatest story of all time. However, it's a movie with a difference – there's no director and no script. The Legacy Survey of Space and Time is one of the most ambitious projects in the world of astronomy, with a mission to create a decade-long time-lapse movie of the visible universe, to answer fundamental questions about its origin, evolution and, ultimately, its fate.Hiranya is Professor of Astrophysics 1909, the prestigious Chair at the Institute of Astronomy at Cambridge University. Over her career she's been one of the pioneers of a revolution in astronomy, bridging fundamental physics with the observational data coming back from space, to establish the first evidence-based standard model for the origin, evolution and fate of the universe. The endeavour has transformed the field from the ‘wild west' of physics to the modern era of precision cosmology.Ironically, it was another movie, of sorts, Carl Sagan's documentary series ‘Cosmos', that first sparked Hiranya's interest in the universe as a young girl. Always keen to inspire women to follow in her footsteps and choose careers in science, if this interview were a live show she'd have reserved the front row for schoolgirls.

In this episode of Talk Nerdy, Cara is joined by British astrophysicist and Royal Society Research Fellow, Dr. Emma Chapman. They discuss her new book The Echoing Universe: How Radio Astronomy Helps Us See the Invisible Cosmos. Releasing in the US tomorrow, 5/19. Follow Emma: @dremmachapman
