SpaceTime with Stuart Gary Gary - Series 29 Episode 16In this episode of SpaceTime, we dive into groundbreaking revelations about Europa's ice shell, explore new evidence for the existence of a potential Planet Nine, and discuss a significant advancement in quantum physics that challenges the Heisenberg Uncertainty Principle.Europa's Ice Shell Thickness RevealedData from NASA's Juno mission has provided the first insights into the thickness of Europa's icy crust, estimating it to be around 29 kilometers. This measurement comes from Juno's 2022 flyby, where the spacecraft utilized its microwave radiometer to analyze the moon's surface temperature and characteristics. The findings suggest that beneath this thick ice lies a global ocean of liquid water, potentially harboring the ingredients necessary for life. Understanding the ice shell's structure is crucial for future missions, including NASA's Europa Clipper, set to arrive in 2030.The Case for Planet NineA new study published in Nature Astronomy presents fresh simulations suggesting that wide-orbit planets, like the hypothesized Planet Nine, could be a natural outcome of chaotic early planetary systems. Researchers found that during turbulent phases of stellar formation, planets can be flung into distant orbits rather than being ejected entirely. This work offers a 40% chance that a Planet Nine-like object exists, providing a promising avenue for future exploration as telescopes become more capable of surveying the distant solar system.Advancements in Quantum PhysicsIn a remarkable breakthrough, physicists have demonstrated a method to sidestep the Heisenberg Uncertainty Principle, allowing for simultaneous precise measurements of a particle's position and momentum. This innovative approach, detailed in Science Advances, could pave the way for ultra-precise sensor technologies across various fields, including navigation and astronomy. The study redefines the boundaries of quantum measurement, offering new possibilities for scientific exploration.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature AstronomyScience AdvancesBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

What does a NASA authorization bill actually do, and why does it matter? In this episode of Space Policy Edition, we dig into one of the most misunderstood but powerful tools Congress uses to shape the future of U.S. space exploration. Host Casey Dreier, chief of space policy at The Planetary Society, is joined by Jack Kiraly, the Society’s director of government relations, for a deep dive into how NASA authorization bills work, how they differ from appropriations, and why they can have decades-long consequences for science missions, human spaceflight, and planetary defense. The discussion also reflects on a major recent win for space advocates: Congress’s bipartisan decision to protect NASA science funding.

There's always been a fuzzy line between asteroids and comets, and new observations of asteroids in the vicinity of Jupiter provide a hint to the origin of the mysterious active asteroids that look like asteroids but act like comets. Elsewhere in the galaxy, the famous ring nebula gets a new spectral image that shows the presence of band of iron. Could it be the remnants of a planet like Earth or Mercury that was vaporized when the nebular formed? Tune in for our take on this, space news, trivia and much more.

What if Europa’s seafloor isn’t alive with activity after all? This week on Planetary Radio, host and producer Sarah Al-Ahmed explores new research that reframes how scientists think about one of the Solar System’s most intriguing ocean worlds. Sarah is joined by Paul Byrne, associate professor of earth, environmental, and planetary sciences at Washington University in St. Louis. Paul is the lead author of a new study suggesting that the seafloor beneath Europa’s global ocean may be geologically quiet today, potentially lacking the hydrothermal activity often associated with habitable environments on Earth. Together, they discuss how scientists investigate places we can’t yet observe directly and why Europa remains a compelling world to explore regardless of what we find. Then, Bruce Betts, chief scientist of The Planetary Society, joins us for What’s Up to explain why Saturn’s moon Enceladus shows strong evidence for active hydrothermal vents beneath its icy crust, offering a fascinating contrast between two ocean worlds.

In this special crossover episode focused on climate action, our friends from Design the Future podcast will join us to discuss the evolution of the sustainable design movement and where it is heading. What can architects do to be part of the solution?The Design the Future podcast is hosted by Lindsay Baker and Kira Gould, two women working at the intersection of the built environment and climate change. Kira and Lindsay will share how they've seen architects leading on climate action, and where the opportunities exist for new leaders to join this work.Guests:Kira Gould is a writer, consultant, and convenor, working from multiple perspectives. As a writer and member of the design media, on staff at and as a consultant to firms, and as a volunteer leader at AIA, she has led the redefinition of design excellence as inclusive of climate action, health, and equity, and emphasized that human and leadership diversity is crucial to advancing all those goals. She is a member of the AIA Committee on the Environment's national Leadership Group. She is a Senior Fellow with Architecture 2030, and was named an Honorary Member of the AIA in 2022. She co-authored Women in Green: Voices of Sustainable Design with Lance Hosey (Ecotone, 2007).As CEO of the International Living Future Institute, Lindsay Baker is the organization's chief strategist, charged with delivering on its mission to lead the transformation toward a civilization that is socially just, culturally rich, and ecologically restorative. Lindsay is a climate entrepreneur, experienced in launching and growing innovative businesses. Her introduction to the green building movement began at the Southface Institute in Atlanta, where she interned before entering Oberlin College to earn a BA in Environmental Studies. She was one of the first 40 staff members at the U.S. Green Building Council, working to develop consensus about what the LEED rating system would become. She then earned an MS from the University of California at Berkeley in Architecture, with a focus on Building Science, and spent five years as a building science researcher at the UC Berkeley Center for the Built Environment.

She was the first Global Head of Sustainability and Impact at WeWork, where she built the corporate sustainability team and programs from scratch. Lindsay is a Senior Fellow at the Rocky Mountain Institute, and a lecturer at UC Berkeley. She serves on several non-profit boards, and is an advisor and board member for numerous climate tech startups.

Our Solar System is wrapped in a vast, invisible bubble created by the Sun, a protective region that shields Earth and the planets from much of the radiation that fills our galaxy. But until recently, scientists have only had rough sketches of what this boundary looks like and how it behaves. In this episode of Planetary Radio, host Sarah Al-Ahmed is joined by David McComas, professor of astrophysical sciences at Princeton University and principal investigator of NASA’s Interstellar Mapping and Acceleration Probe (IMAP) and Interstellar Boundary Explorer (IBEX) missions, along with Matina Gkioulidou, a heliophysicist at Johns Hopkins Applied Physics Laboratory, former IMAP-Ultra instrument lead, and current IMAP project scientist and co-investigator. Now stationed at the Sun–Earth L1 Lagrange point, IMAP uses 10 instruments to study the heliosphere — the region where the solar wind collides with material from interstellar space. The mission does this by tracking energetic neutral atoms, particles that travel in straight lines from distant regions of the heliosphere, allowing scientists to map areas of space that spacecraft can’t directly sample. McComas and Gkioulidou explain how IMAP builds on the legacy of Interstellar Boundary Explorer, what makes this mission different, and why understanding the Sun’s influence across space matters not just for fundamental science, but for space-weather forecasting and protecting technology and astronauts closer to home.

What does it really mean to enter interstellar space, and what have we learned since humanity first crossed the invisible boundary between our Sun and the stars? In this episode of Planetary Radio, we explore the science of the heliosphere and the realm beyond with Linda Spilker, project scientist for the Voyager mission at NASA Jet Propulsion Laboratory. Drawing on decades of experience with the twin spacecraft, Spilker shares how Voyager reshaped our view of the Solar System’s outer frontier, from the nature of the heliopause to the unexpectedly rich structure of the local interstellar medium. We unpack what Voyager 1 and Voyager 2 have taught us about charged particles, magnetic fields, and cosmic rays beyond the Sun’s protective bubble, and why those measurements have upended earlier ideas about where the Solar System truly ends. Spilker also reflects on the mission’s extraordinary longevity, the ingenuity required to keep the spacecraft communicating across the vastness of space, and what Voyager’s legacy means for future journeys between the stars. Then, in What’s Up, Bruce Betts, chief scientist at The Planetary Society, places Voyager in context, showing how long-lived missions shape the bigger picture of space science and why observing longer can lead to some of our most profound discoveries.

Marcia Smith, the founder and editor of Space Policy Online, joins the show and revisits a conversation we had one year ago, recorded just weeks before the second Trump administration took office. That episode, “The Challenges of Change at NASA,” explored the institutional and political roadblocks to radical change at the U.S. space agency. A lot has happened since that show, including DOGE, mass staff departures, a draconian budget cut proposal, a dramatic shift toward sending humans to Mars, and the rapid departure of 20% of NASA's workforce. But at the end of the year, much remains the same. The SLS and Orion programs continue unchanged, with funding locked in through 2032. The humans-to-Mars policy has effectively vanished; returning U.S. astronauts to the Moon, to stay, is again centered within civil space policy. NASA's science missions, though still facing a serious budgetary threat, have not gone away. So, did we see real change at NASA? And to what end? Or was it merely disruption masquerading as change? Marcia Smith and host Casey Dreier revisit their original analysis and discuss what they got wrong, what they got right, and what surprised them about 2025 in civil space policy.

1.1.26 – Day 10/13 of the White Wizard Wavespell – Rhythmic Moon 20

At the dawn of the 19th century, the celestial police were on patrol. They were looking for a planet between the orbits of Mars and Jupiter. And on the century’s first day, a future squad member found one – sort of. Later discoveries showed that it wasn’t a planet at all, but the first and largest member of the asteroid belt – a wide band of millions of rocky bodies. Astronomers were looking for a planet because of the numbers. There seemed to be a mathematical relationship between the distances from the Sun to the known planets. But there was a gap between Mars and Jupiter. So one astronomer began organizing a search party: the celestial police. Giuseppe Piazzi, at the Palermo Observatory in Sicily, was on the list of people to invite. But he was already searching on his own. And before he got his invitation, he found something – 225 years ago today. Piazzi originally thought it was a comet – but hoped for something bigger. As other astronomers began studying it, they decided it was the sought-after planet. They named it Ceres, for the Roman goddess of agriculture. Within a few years, though, they’d found several other bodies in similar orbits. So they realized that Ceres wasn’t a planet at all, but just one member of a band of debris – the asteroid belt. Today, Ceres has regained its planetary status – sort of. It’s a dwarf planet – the only one in the inner solar system. Script by Damond Benningfield

SpaceTime with Stuart Gary Gary - Series 28 Episode 153In this episode of SpaceTime, we dive into thrilling new missions and groundbreaking discoveries in the universe.Ramses Mission to Asteroid ApophisThe European Space Agency has greenlit an exciting new mission to study the infamous doomsday asteroid Apophis. The Ramses spacecraft will closely observe the 450-meter-wide asteroid as it makes a close flyby of Earth on April 13, 2029, at a mere 32,000 kilometers away—closer than many satellites. Initially feared to be on a collision course with Earth, further observations have since ruled out the threat of impact. However, the Ramses mission aims to understand how Earth's gravitational forces might affect Apophis during this close encounter, potentially setting the stage for future impacts. The spacecraft will deploy smaller probes to monitor changes in Apophis's orbit, rotation, and surface, providing vital data for planetary defense and insight into the evolution of asteroids.Solving the Mystery of ExistenceIn a groundbreaking study, scientists at CERN have made strides in explaining the universe's existence by observing a slight imbalance in the behavior of matter and antimatter. This charge parity (CP) violation suggests that a tiny difference favored matter over antimatter during the Big Bang, allowing the universe to evolve into its current state. The findings, based on 80,000 decays of the Lambda beauty particle, indicate a significant deviation that could reshape our understanding of the cosmos.The Largest Planetary Nursery Ever SeenAstronomers have discovered the largest planetary nursery ever observed, located in a massive protoplanetary disk around a young star. This chaotic environment, cataloged as IRAS230776707, spans an astonishing 650 billion kilometers and showcases intricate structures that hint at the complex processes of planet formation. The observations, made using NASA's Hubble Space Telescope, reveal a unique perspective on how planetary systems may develop in extreme conditions, raising new questions about the dynamics shaping these disks.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical JournalNatureCERN ReportsBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.(00:00:00) This is Space Time Series 28, Episode 153 for broadcast on 29 December 2025(00:00:47) ESA's Ramses mission to study asteroid Apophis(00:12:30) CERN's discovery of matter-antimatter imbalance(00:20:10) Astronomers observe the largest protoplanetary disk ever found(00:25:00) New insights into sleep apnea and mental health risks(00:28:30) Potential discovery of a new ancient human species

We're in the midst of an environmental crisis, and our urban lifestyles often clash with the natural systems that support us — especially when it comes to how we manage our waste.Stopping the flow of cross-border pollution can feel like a Sisyphean task. With every effort to tackle it, more trash seems to appear. That's why addressing the pollution crisis at the border takes a multifaceted approach. It involves many different types of interventions — from trash barriers to hillside reforestation to trash collection and repurposing efforts.In this fourth and final installment of The Planetary Scale, we talk with four fronterizos who have been at the forefront of efforts to mitigate this issue and check back in with old friends from six years ago.

For a quarter of each Uranian year, half of the planet is plunged into a twenty-one-year winter of total darkness.

In this episode, we take a deep dive into the cosmic events and scientific discoveries that await us in 2026. We kick off with an exciting preview of lunar exploration, as NASA's Artemis program prepares to send astronauts on a historic flyby of the Moon, alongside a fleet of robotic landers from various commercial companies, including Jeff Bezos's Blue Moon. Next, we highlight the total solar eclipse on August 12, which will cross the Arctic, as well as a ring of fire eclipse in Antarctica, making 2026 a year for eclipse chasers.Shifting our focus to the edge of our solar system, we discuss the latest findings from the Voyager probes, which have uncovered a "wall of fire" at the boundary of the heliosphere, challenging our understanding of solar and interstellar interactions.

12.19.25 – Day 10/13 of the Red Dragon Wavespell – Rhythmic Moon 7

Thirty years ago, NASA’s Galileo spacecraft became the first mission to orbit Jupiter, opening a new chapter in our exploration of the outer Solar System. Over eight years around Jupiter, Galileo transformed how we understand Jupiter and its moons, revealing a powerful and dynamic planetary system, uncovering evidence for oceans hidden beneath icy worlds, and reshaping the search for life beyond Earth. To mark the 30th anniversary of Galileo’s orbital insertion, scientists, engineers, historians, and advocates gathered at the California Institute of Technology for a special symposium: Galileo at 30. In this episode of Planetary Radio, host Sarah Al-Ahmed takes you inside that celebration. You’ll hear how Galileo survived seemingly impossible challenges, how its team adapted when things went wrong, and how its discoveries reshaped planetary science. You’ll hear from key voices in Galileo’s story, including historian Erik Conway, project manager Bill O’Neil, magnetometer principal investigator Margaret Kivelson, Europa Clipper Project Scientist Bob Pappalardo, and Dragonfly mission Principal Investigator Elizabeth “Zibi” Turtle, along with reflections from many others whose lives and careers were shaped by this remarkable mission. Together, they tell the story of Galileo not just as a spacecraft, but as a shared human effort, one whose legacy continues to guide exploration today.

In this episode of SpaceTime, we explore significant developments in space exploration and cosmic studies that could reshape our understanding of the universe.Nasa's MAVEN Mars Orbiter: Communication LossNASA's MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft has gone silent, with contact lost on December 6th after passing behind Mars. The orbiter has been a vital asset for over a decade, studying the Martian atmosphere and solar wind interactions that have transformed Mars from a water-rich world to a cold desert. We delve into MAVEN's critical findings, including the mechanisms of atmospheric escape and the implications of its potential loss for ongoing Martian research.Galactic Neighbourhoods: Influencing EvolutionA new study reveals how a galaxy's local environment can significantly affect its evolution. The research, published in the Monthly Notices of the Royal Astronomical Society, demonstrates that galaxies situated in densely populated regions tend to grow more slowly and develop different structures compared to their isolated counterparts. By analysing data from the Deep Extragalactic Visible Legacy Survey, astronomers have gained insights into the complex dynamics of galactic interactions and their impact on star formation rates.Uranus and Neptune: More Richie than Icy?Challenging long-held classifications, a recent study suggests that the solar system's ice giants, Uranus and Neptune, may actually be more rocky than icy. Researchers from the University of Zurich conducted computer simulations that indicate a broader range of internal compositions for these planets, which could explain their complex magnetic fields. This new perspective could alter our understanding of planetary formation and evolution, paving the way for future explorations of these distant worlds.www.spacetimewithstuartgary.com✍️ Episode ReferencesMonthly Notices of the Royal Astronomical SocietyNASA TVBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

This revelation, published in the Astrophysical Journal Letters, highlights the complex movements of Cepheid variable stars within the galaxy, indicating that it is being stretched in multiple directions. By utilizing data from the European Space Agency's Gaia satellite, researchers have gained unprecedented insights into the interactions between these two galaxies, prompting a reevaluation of their structural dynamics and gravitational relationships with the Milky Way.Europa's Spider: Signs of Subsurface Water?A striking spider-like feature on Jupiter's moon Europa has scientists buzzing with excitement. Researchers suggest this formation, found near the Menanan impact crater, may be evidence of subsurface water seeping through the moon's icy crust following an asteroid impact. The findings, reported in the Planetary Science Journal, could have significant implications for the moon's habitability and the presence of life. By drawing parallels with similar features on Mars, scientists are eager to explore Europa's subsurface properties further, especially with the upcoming Europa Clipper mission set to launch in April 2030.Mars: A Longer Habitable History?New research indicates that Mars may have been habitable for a much longer duration than previously believed. A study published in the Journal of Geophysical Research Planets reveals that ancient underground water may have flowed beneath the Martian sand dunes, creating conditions conducive to life long after its surface water disappeared. This discovery not only enhances our understanding of Mars' geological history but also highlights the potential of subsurface environments as targets for future exploration in the search for past life.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journal LettersPlanetary Science JournalJournal of Geophysical Research PlanetsBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

Could you survive an eternal winter? Or is endless summer sun a more appealing prospect? Lots of us are grateful for the seasonal changes that shape the world around us, but this week Hannah and Dara are asking what life would look like without the axial tilt that brings each hemisphere closer and further away from the sun as the seasons change each year. Listener Andrew from Melbourne wants to know what would happen if the planet stood perfectly upright, no lean, no tilt, no seasons. But what else could happen? Is Earth's 23-degree slant the cosmic fluke that made life possible? To find out, Hannah and explore how losing the tilt reshapes climate, ecosystems, evolution and maybe even the fate of the dinosaurs.You can send your everyday mysteries for the team to investigate to: curiouscases@bbc.co.uk Contributors Dr Robin Smith - Climate modelling researcher at the University of Reading Professor Rebecca Kilner - Evolutionary Biologist and Head of the Department of Zoology at Cambridge Professor Amaury Triaud - Professor of Exoplanetology at the University of Birmingham Aidan McGivern - Meteorologist and Senior weather presenter at the MET OfficeProducer: Emily Bird Executive Producer: Sasha Feachem A BBC Studios Production

NASA’s twin ESCAPADE spacecraft have finally launched on their journey to Mars. Designed to study how the solar wind interacts with Mars’ patchy magnetic fields and drives the loss of its atmosphere, ESCAPADE is NASA’s first dual-spacecraft mission to the Red Planet and a major milestone for the SIMPLEx program’s small, low-cost planetary explorers. The mission began its voyage aboard Blue Origin’s New Glenn rocket after several weather and space weather delays, marking the vehicle’s first science launch. We begin with Ari Koeppel, AAAS Science & Technology Policy Fellow and Space Policy Intern at The Planetary Society, who was at Cape Canaveral for the prelaunch activities. Ari shares what it was like to navigate repeated scrubs and even a powerful solar storm, along with the emotional experience of watching a spacecraft carrying an instrument he helped build begin its voyage to Mars. Next, we are joined by Dr. Rob Lillis, ESCAPADE’s Principal Investigator and Associate Director for Planetary Science at UC Berkeley’s Space Sciences Laboratory. Rob explains how ESCAPADE aims to unravel Mars’ complex space environment using two coordinated orbiters, why its measurements are key to understanding atmospheric escape, and how its innovative trajectory made the mission possible after the loss of its original rideshare opportunity. Finally, Dr. Bruce Betts, Chief Scientist of The Planetary Society, returns for What’s Up to talk about why Mars produces aurora even without a global magnetic dynamo.

8/8. Global Bird Consciousness and Human Responsibility — Steven Moss — Moss concludes by emphasizing that birds represent profound indicators of planetary ecological health and human stewardship. Moss argues that human societies have repeatedly demonstrated catastrophic ecological mismanagement—from deliberate species eradication campaigns to inadvertent pesticide-driven collapse of insect populations supporting avian food chains. Moss stresses that contemporary climate-driven extinctions represent an acceleration of anthropogenic ecological destruction. Mossemphasizes that conservation requires fundamental shifts in human consciousness regarding our responsibility to non-human species and ecosystem integrity, using birds as both biological indicators and moral catalysts for sustainable civilization transformation. 1848

1/4. The Genesis of the Asteroid Hunter Mission and Early Rejections — Dante Lauretta — Lauretta, hired by mentor Mike Drake at the Lunar and Planetary Laboratory (LPL), initiated the asteroid sample return mission concept in 2004 following a pivotal meeting with Lockheed Martin's Steve Price. The team submitted its initial proposal to NASA in July 2004, which received the agency's lowest competitive ranking, designated Category 4. A subsequent refined mission proposal targeting asteroid 1999 RQ36 was formally rejected in December 2007 due to prohibitively high estimated costs relative to the NASA planetary science program budget allocation. 1930
