Podcasts about Planetary science

Astronomers using the James Webb Space Telescope have observed clouds on a hot gas giant exoplanet called WASP-94A b, some 700 light-years away. But these clouds aren't your usual wisps of water vapor—they're vaporized sand. Astronomer David Sing joins Host Flora Lichtman to describe the planetary weather, and how the researchers were able to observe it.  Then, ecologist Elske Tielens joins Flora to describe how ecologists using weather radar data counted the insects aloft in U.S. skies: around 100 trillion of them on an average summer day. Guests: Dr. David Sing is a Bloomberg Distinguished Professor of Earth and Planetary Sciences at Johns Hopkins University. Dr. Elske Tielens is an ecologist with the Swiss Federal Institute for Forest, Snow and Landscape Research.

That is, more or less, where NASA stood when Artemis 1 left the pad — and where it stands now, with Artemis 2 having put humans beyond low Earth orbit for the first time in half a century. The institutional memory had thinned. The people who built Apollo had moved on, retired, or passed away. The books, as Dr. Alex Polanski puts it in this episode, had to be dusted off. Polanski, a Percival Lowell postdoctoral fellow at Lowell Observatory in Flagstaff, Arizona, joins host Matt to talk about what Artemis 2 actually proved, and why Lowell — an observatory better known for its exoplanet work and its founder's obsession with Mars — has always sat closer to crewed spaceflight than most people realize. The nine Apollo astronauts trained on the volcanic terrain of northern Arizona. They studied lunar maps made at Lowell. They walked the same ground tourists walk today, in the shadow of the Clark refractor. The conversation moves from the geology of the Moon's Highlands and Maria to the meteorite work of Dr. Nick Moskowitz, the mapping happening at the USGS office down the road, and the longer question behind all of it: is the Moon a stepping stone to Mars, or a detour? Polanski makes the case for the stepping stone — not out of caution, but because there are things we don't yet know we need to know, and a one-second light delay is a much more forgiving classroom than a twenty-minute one. And then there's what comes next. Radio telescopes in the craters of the far side, shielded from Earth's noise. Optical interferometers spread across lunar real estate, free of the atmospheric wobble that makes ground-based astronomy feel, in Polanski's words, like reading a note card at the bottom of a pool. For the first time, the possibility of actually seeing the surfaces of other stars. Percival Lowell saw canals on Mars that weren't there. He may have been looking at the veins in his own eye. A century later, his observatory is helping figure out how to look at the real thing.

The Lazuli Space Telescope is slated to be the first of its kind to be completely funded by private dollars. University of Arizona planetary scientist Ewan Douglas discusses the spacecraft designed to be larger than the Hubble Space Telescope, which was launched in 1990. Ewan Douglas spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

A key development in the history of the early Earth is the formation of lithospheric plates that move independently of one another. In this episode, Brenner describes how he used paleomagnetic methods to detect relative motion between two ancient cratons, the East Pilbara and the Kaapvaal, 3.5 billion years ago. This is a full billion years earlier than any previous such detection, and it enables us to narrow down the kind of tectonics operating in the Paleoarchean. Of the candidate regimes, episodic subduction models fit his data best. Brenner is a Postdoctoral Associate in the Department of Earth & Planetary Science at Yale University.

Dr. Lindy Elkins-Tanton, Space Sciences Laboratory at the University of California, Berkeley,Apr. 8, 2026.The NASA Psyche mission is on its way to orbit a small but immensely ancient world in our asteroid belt: A metallic object, the first humans will ever have visited. When our solar system was in its infancy, thousands of planetesimals (tiny planet-like objects) formed in less than a million years. Many planetesimals later melted, allowing metal cores to form inside rocky mantles. One of these metal cores may be revealed in the asteroid (16) Psyche. Dr. Elkins-Tanton, the Mission Lead, takes us behind the scenes in planning and carrying out this remarkable mission of exploration, which launched in 2023, and updates us of where we are over two years post-launch.

Over his career Dr. Bill Dietrich has had an outsized influence on both the discipline of geomorphology and the community that surrounds the discipline.  He is Professor Emeritus in the Department of Earth and Planetary Science at the University of California, Berkeley. Dr. Dietrich is one of the most influential geomorphologists of the last several decades, known for developing process-based theories of landscape evolution and geomorphic transport laws for soil production, hillslope transport, and river incision. His work spans hillslopes, rivers, debris flows, sediment transport, and the coupling of ecological and geomorphic processes. Over his career he has helped establish many of the conceptual and quantitative frameworks that modern geomorphology relies on today, and his publications are close to 70,000 citations (which is a truely astounding number). He was elected to the U.S. National Academy of Sciences in 2003 and has received several of the field's highest honors, including the Robert E. Horton Medal of the American Geophysical Union for outstanding contributions to hydrology and the G.K. Gilbert Award for major advances in Earth-surface processes, which is apt because I see his work embodying Gilbert's tradition.  Bill also began "the Gilbert Club" an AGU adjacent gathering that has become a center of mas for the geomorphic community, which we talk about in the episode.As I try to grow in my ability to predict river behavior and manage our interactions with our nation's waterways, I find I'm learning - approximately in equal parts - from the worlds of engineering and geomorphology, so I am trying to deliver heuristics and insights from those overlapping - but separate - thought worlds.  In this episode we go deep into the science of upland river processes, including insights that have helped me along the way.We will have some bonus content on the YouTube channel...but you won't want to miss this: https://youtu.be/fixiMpBB3LE(an easter egg priview for the people who read episode notes)This series was funded by the Regional Sediment Management (RSM) program.Mike Loretto edited the first three seasons and created the theme music.Tessa Hall is editing most of Season 4.Stanford Gibson (HEC Sediment Specialist) hosts.Video shorts and other bonus content are available at the podcast website:https://www.hec.usace.army.mil/confluence/rasdocs/rastraining/latest/the-rsm-river-mechanics-podcast...but most of the supplementary videos are available on the HEC Sediment YouTube channel:https://www.youtube.com/user/stanfordgibsonIf you have guest recommendations or feedback you can reach out to me on LinkedIn or ResearchGate or fill out this recommendation and feedback form: https://forms.gle/wWJLVSEYe7S8Cd248

COVID 19 became part of our lives as a global pandemic in March of 2020. Since then, scientists have tracked the phenomenon of Long COVID, where symptoms have lasted well after the patient has recovered. University of Arizona medical professor Sairam Parthasarathy discusses the ongoing research into Long COVID and why so many questions about the disorder remain unanswered. Sairam Parthasarathy spoke with Tim Swindle, professor emeritus in Planetary Science at the University of Arizona.

More than perhaps any other state, Hawaii has major incentives to decarbonize. Imported oil accounts for about 90% of Hawaii's total energy consumption, and electricity prices are more than three times the national average. So it may not be surprising that Hawaii was the first state in the nation to set a 100% renewable energy goal by 2045. But that's a hard goal to achieve, especially given the realities of geographic isolation and the costs of importing fuel and materials.  Hawaii Governor Josh Green is bullish about the island state's decarbonization and wants all options on the table. That includes making liquified natural gas part of the mix, along with solar, wind, and geothermal. His administration passed the first “green fee” which imposes a tax on Hawaii visitors and is expected to generate $100 million for climate resilience projects.

In this episode, we discuss… What science really is, both as body of knowledge and a constantly evolving process  Why one study is never enough and the importance of multiple methods, reproducibility, and scientific consensus over time When "gold standard" research falls short and why fields like nutrition require more flexible, creative approaches Science's built-in caution and how new ideas face a high bar of proof, slowing acceptance but strengthening reliability How doubt is manufactured, from the tobacco era to climate science, using fringe voices to challenge strong consensus The role of ideology, and how "freedom" narratives can shape public resistance to scientific evidence Acting without certainty and why we must make public health decisions even when data isn't 100% complete AI and misinformation and the promise and risk of tools like OpenAI in shaping how we consume science Naomi Oreskes Henry Charles Lea Professor of the History of Science Affiliated Professor of Earth and Planetary Sciences ON LEAVE SPRING 2026 emailoreskes@fas.harvard.edu Faculty Assistant: Yaz Alfata Primary Areas of Research: Agnotology; the Political Economy of Scientific Knowledge; History and Philosophy of Earth and Environmental Sciences, Science and Technology Studies (STS); the History of Climate Change Disinformation Secondary Areas of Interest: Science Policy, Science and Religion, Women and Gender Studies   Naomi Oreskes is Henry Charles Lea Professor of the History of Science and Affiliated Professor of Earth and Planetary Sciences at Harvard University.

In an area which is about 1/400th of the entire sky, the NASA Kepler spacecraft has discovered 30 Earth like planets which are likely to have liquid water on their surfaces orbiting distant stars. These planets are likely to represent a tiny sample of the habitable planets which exist in the Milky Way. In spite of our efforts to find them, the question remains where are the alien civilizations? In a recent talk given at the Division of Planetary Sciences meeting Dr. Alan Stern of the Southwest Research Institute suggests that perhaps the majority of worlds with biology and intelligent civilizations exist on interior water ocean worlds where their existence is hidden by the thick layers of rock and ice which separate them from the hostile vacuum of space. We know that in our solar system alone the moon of Jupiter Europa, Saturn's moon Enceladus, and perhaps several other small worlds are likely to have oceans of nutrient rich liquid water covered by a thick layer of rock and ice. We also know that Whales and Dolphins have larger brains than humans, communicate with each other, and exhibit other forms of intelligence. Advanced civilizations existing in ice covered seas may know little of the greater Universe, may find it difficult to consider transporting enough water to travel beyond their worlds, and may not think that it is possible to communicate with others of their kind who are similarly hidden under miles and miles of radiation absorbing ice and rock.

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.

After 27 years, Melvyn Bragg has decided to step down from the In Our Time presenter's chair. With over a thousand episodes to choose from, he has selected just six that capture the huge range and depth of the subjects he and his experts have tackled. In this first pick, we hear Melvyn Bragg and his guests discuss the origins, science and mythology of the moon. Humans have been fascinated by our only known satellite since prehistory. In some cultures the Moon has been worshipped as a deity; in recent centuries there has been lively debate about its origins and physical characteristics. Although other planets in our solar system have moons ours is, relatively speaking, the largest, and is perhaps more accurately described as a 'twin planet'; the past, present and future of the Earth and the Moon are locked together. Only very recently has water been found on the Moon - a discovery which could prove to be invaluable if human colonisation of the Moon were ever to occur.Mankind first walked on the Moon in 1969, but it is debatable how important this huge political event was in developing our scientific knowledge. The advances of space science, including data from satellites and the moon landings, have given us some startling insights into the history of our own planet, but many intriguing questions remain unanswered.With:Paul Murdin Visiting Professor of Astronomy at Liverpool John Moores UniversityCarolin Crawford Gresham Professor of Astronomy at the University of CambridgeIan Crawford Reader in Planetary Science and Astrobiology at Birkbeck College, London.Producer: Natalia FernandezSpanning history, religion, culture, science and philosophy, In Our Time from BBC Radio 4 is essential listening for the intellectually curious. In each episode, host Melvyn Bragg and expert guests explore the characters, events and discoveries that have shaped our world.

There are three main types of geodetic measurement systems — satellite-based systems such as GPS, very long baseline interferometry (VLBI), and interferometric synthetic-aperture radar (InSAR). While each type of systems has its particular strengths, the cost of satellite-based receivers has plummeted. Millimeter-level accuracy will soon be incorporated into phones. This has broadened the kinds of geological questions we can now address with such systems. In the podcast, Tom Herring describes how these systems are giving us new insight into plate motions, slow and fast deformation associated with faults and earthquakes, the Earth's rotation, as well as applications in civil engineering, such as dams and tall buildings, and agriculture.Herring is a pioneer in high-precision geodetic analytical methods and applications for satellite-based navigation systems to study the Earth's surface.  He is a Professor in the Earth, Atmospheric, and Planetary Sciences department at the Massachusetts Institute of Technology.

The universe is hard enough to figure out without one kind of object dressing up as another, but - just in time for Halloween - researchers have figured out that the Little Red Dot in the early universe just might be massive black holes surrounded in a costume of glowing red gas. Also in this episode, Hyabusa2's amusingly tiny destination, a white dwarf star eating what may be an icy dwarf planet, and tales from the launch pad.

Dr. Konstantin Batygin, professor of Planetary Science at Caltech, made a joke that turned out to be true. In 2014, another Caltech professor, Mike Brown, brought an intriguing research paper to Batygin's attention. The paper described a peculiar planetary alignment in the outer solar system. While developing theoretical models to explain the paper's assertions, Brown and Batygin had a running gag, "We were like, okay, as a joke, let's put a planet in the outer solar system just to see what would happen." In this episode of Looking Up, Dean Regas chats with Dr. Batygin and gets the full story.

Billions of years ago, Mars may have looked less like the barren red desert we know today and more like Earth—with a blue sky, flowing rivers, and even seas. What happened to turn a once-habitable world into the frozen, lifeless planet we see now?On this episode of Big Brains, University of Chicago geophysical scientist Edwin Kite takes us on a journey through Mars' hidden past. From evidence of a lost carbon cycle to theories about ancient climate swings, Kite's research is rewriting the story of the Red Planet. But it's not just about the past—his work is also at the forefront of a provocative question: could humanity one day terraform Mars and make it a living world again?
