We’ve turned intuition into a buzzword—flattened it into a slogan, a gut feeling, or a vague whisper we don’t always know how to hear. But what if intuition is so much more? What if it's one of the most powerful tools we have—and we’ve just forgotten how to use it? In this episode, I’m joined by Hrund Gunnsteinsdóttir , Icelandic thought leader, filmmaker, and author of InnSæi: Icelandic Wisdom for Turbulent Times . Hrund has spent over 20 years studying and teaching the science and art of intuition through her TED Talk, Netflix documentary (InnSæi: The Power of Intuition), and global work on leadership, innovation, and inner knowing. Together, we explore what intuition really is (hint: not woo-woo), how to cultivate it in a culture obsessed with logic and overthinking, and why your ability to listen to yourself might be the most essential skill you can develop. In This Episode, We Cover: ✅ Why we’ve misunderstood intuition—and how to reclaim it ✅ Practical ways to strengthen your intuitive muscle ✅ What Icelandic wisdom teaches us about inner knowing ✅ How to use intuition during uncertainty and decision-making ✅ Why trusting yourself is an act of rebellion (and power) Intuition isn’t magic—it’s a deep, internal guidance system that already exists inside you. The question is: are you listening?

A Cookbook of Life: How Chemistry Might Explain Life on Other Planets 29:39

4 days ago29:39

29:39

What if the origin of life isn’t a one-in-a-billion cosmic fluke, but something that happens whenever the conditions are just right? Join communications specialist Beth Johnson as we explore groundbreaking research from the University of Wisconsin–Madison, where scientists have identified over 270 self-replicating chemical reactions that may have sparked life, not just on Earth, but potentially anywhere in the universe. Led by astrobiologist Dr. Betül Kaçar, this study reframes our understanding of how life can emerge from simple chemistry. Discover how these "chemical recipes" might reveal a universal pattern for life, help us search distant planets more effectively, and bring us one step closer to answering one of humanity’s biggest questions: Are we alone?

Red Planet, Blue Past: How Rain Shaped the Martian Landscape 33:21

11 days ago33:21

33:21

A groundbreaking study from the University of Colorado Boulder suggests that ancient Mars was far from the cold, arid planet we know today. Led by Amanda Steckel, the research team utilized computer simulations to reveal that billions of years ago, Mars experienced significant precipitation—either rain or snow—that carved out extensive networks of valleys and channels across its surface. These findings challenge previous theories that Mars was predominantly cold and dry, instead supporting the idea of a warmer, wetter climate during the Noachian epoch, approximately 4.1 to 3.7 billion years ago. The study provides compelling evidence that precipitation played a crucial role in shaping the Martian landscape, offering new insights into the planet's climatic history and its potential to have supported life. Join planetary scientist Beth Johnson and Dr. Steckel as they discuss the results of this study and its implications for finding life, especially past life, on Mars. (Recorded live 8 May 2025.)…

Tiny Asteroids, Big Threats: JWST Reveals a Hidden World of Mini Asteroids 31:21

18 days ago31:21

31:21

One significant threat to life here on Earth is the possibility that a massive asteroid will collide with our planet and destroy life as we know it. To understand the possibilities, large surveys of the sky have found around 95% of potentially hazardous asteroids larger than a kilometer. Smaller asteroids, however, can also cause massive amounts of damage. Estimates range from 40 to 60 percent when it comes to asteroids over 100 meters in diameter, which would be considered city-killers. Even smaller asteroids, such as the 20-meter one that exploded over Chelyabinsk in 2013, can cause destruction and injury. The more asteroids we can find, the better our predictions and future protections will be. In light of this threat, scientists have used the JWST to detect 138 of the smallest asteroids (as small as 10 meters) ever observed in the asteroid belt. These tiny asteroids are important because they can become near-Earth objects (NEOs), posing a risk to Earth through possible impacts, including powerful explosions. By analyzing the size and frequency of asteroids, researchers found a significant change in the population of asteroids around 100 meters in size, likely due to collisions breaking larger asteroids into smaller ones. The observed asteroids originated from known asteroid families and were detected using advanced tracking and infrared imaging techniques. This research enhances our understanding of asteroid behavior and may aid in predicting and mitigating future asteroid threats. Join planetary astronomer Franck Marchis in a conversation with lead authors Artem Y. Burdanov and Julien de Wit as they discuss these smaller asteroids and what they can reveal about potential threats to our planet. (Recorded live 1 May 2025.)…

Is Intelligent Life Easy? Human-Like Life Probably Evolves "Right on Time" 30:08

25 days ago30:08

30:08

A recent study proposes a new model for the evolution of intelligent life, which challenges the long-standing "hard steps" theory that the emergence of intelligent life is an exceedingly rare event due to a series of improbable evolutionary milestones. A team led by postdoctoral researcher Dan Mills from the University of Munich suggests that the development of intelligent life is a natural outcome of planetary evolution. They argue that Earth's environment underwent sequential "windows of habitability," periods when conditions became favorable for complex life to emerge. (Past Drake Award winner Jason Wright is a co-author on the study.) The study emphasizes the importance of interdisciplinary collaboration between astrophysics and geobiology to understand the evolution of life. Join planetary astronomer Franck Marchis in an in-depth discussion with Dr. Mills about why intelligent life may be common and how this could affect our search for life beyond Earth.

A road trip to a gypsum quarry in Algeria led Youcef Sellam on a journey of scientific discovery. From the road trip to an internship in Italy, he and his colleagues later discovered microbial fossils—marking a first for Algerian gypsum. As a Ph.D. student at the University of Bern, Sellam and his team took this research further. They used a special instrument to detect the chemical signatures of these ancient microbes, demonstrating a method that could one day help search for traces of life on Mars. Their findings, published in Frontiers in Astronomy and Space Sciences, highlight how chemical analysis can reveal biological traces in minerals. Join planetary scientist Beth Johnson and Youcef for a discussion of how this research brings us one step closer to understanding how we might detect past life on the Red Planet.

Why is Mars Red? New Research Suggests Ferrihydrite is the Key 33:38

7 weeks ago33:38

33:38

In a recent study, Dr. Janice Bishop of the SETI Institute, along with postdoctoral researcher Adomas Valantinas from Brown University, propose that Mars' characteristic red hue is primarily due to ferrihydrite—a water-rich iron oxide mineral—rather than the previously assumed hematite. Analyses of data collected by Martian orbiters, rovers, and laboratory experiments showed that ferrihydrite closely matches the composition of the dust covering Mars' surface. Ferrihydrite typically forms in environments abundant in cool water, suggesting Mars once had significant liquid water on its surface. The research implies that Mars transitioned from a wet to a dry environment billions of years ago. Confirming these findings would require returning samples from Mars to Earth for comprehensive analysis. Join planetary scientist Beth Johnson for a chat with Dr. Bishop about the evidence for ferrihydrite and what it could have meant for life on Mars. (Recorded live 3 April 2025.)…

26:20

With over 7,000 exoplanets identified in our galaxy, scientists are shifting their focus to studying these worlds' characteristics in the quest for extraterrestrial life. The backdrop for one team is the discovery of super-Earth HD 20794 d, an exoplanet detected by researchers from the University of Geneva (UNIGE) and NCCR PlanetS. Orbiting in an eccentric path, HD 20794 d moves in and out of its star’s habitable zone, making it a compelling subject for further study. This breakthrough, built on two decades of observations with the world’s most advanced telescopes, has just been published in Astronomy & Astrophysics.

The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) mission has been a resounding success, from taking a sample of asteroid Bennu to returning that sample to Earth. The first in-depth analysis of the space rocks is complete, and the results have been published in Nature and Nature Astronomy. One of the most intriguing results shows that 14 of the 20 amino acids life on Earth uses to form proteins have been found in the sample. This result supports the hypothesis that objects that formed farther from the Sun provided precursor ingredients for life.

A PUNCH for the Sun: NASA’s Polarimeter to Unify the Corona and Heliosphere 36:23

11 weeks ago36:23

36:23

NASA’s Polarimeter to Unify the Corona and Heliosphere, or PUNCH mission, is a constellation of four small satellites in low Earth orbit that will make global, 3D observations of the Sun’s corona to better understand how the mass and energy there become the solar wind that fills the solar system. Imaging the Sun’s corona and the solar wind together will help scientists better understand the entire inner heliosphere—the Sun, solar wind, and Earth—as a single connected system. Solar wind and energetic solar events like flares and coronal mass ejections can create space weather effects throughout the solar system. These phenomena can significantly impact human society and technology, sparking and intensifying auroras, interfering with satellites, and triggering power outages. The measurements from PUNCH will provide scientists with new information about how these potentially disruptive events form and evolve. This could lead to more accurate predictions about the arrival of space weather events at Earth and the impact on humanity’s robotic explorers in space. The launch of PUNCH and the SPHEREx mission is scheduled for no earlier than 27 February 2025 from Vandenberg SFB. Simon Steel, Deputy Director of the Carl Sagan Center, and MUSE Outreach Lead Rebecca Robinson will attend the launch and return to the SETI Institute for a chat about the mission, its scientific goals, and its relevance to understanding life on Earth.

During his time as an Artist in Residence (AIR) at the SETI Institute, visual artist, psychiatrist, and psychoanalyst Martin Wilner invited prominent SETI Institute scientists to participate in his ongoing project, The Case Histories. Interested in exploring how scientists relate to the possibility of encountering an alien life form, Wilner invited researchers such as Jill Tarter, Seth Shostak, and Franck Marchis to send him daily messages and share thoughts of interest. These messages, filtered through the prism of psychoanalytical principles, were then transformed into drawings and visualized as daily elements of a calendar. More recently, Wilner has expanded his conversations into the realm of AI, an “alien” intelligence that is already in our midst. In this conversation, hosted by SETI AIR Director Bettina Forget, discover how Wilner weaves connections between the human mind, machine learning, consciousness, and our ideas about extraterrestrial life.

Over the past decade, NASA's Lunar Reconnaissance Orbiter (LRO) has captured thousands of high-resolution images of the Moon's surface—far more than humans can manually review. To tackle this challenge, scientists have developed an automated system that quickly identifies scientifically significant images from the LRO data, making it the first anomaly detector for planetary imagery. Experiments show that the system reliably highlights unusual features, such as striking geological formations and sites of human landings or spacecraft crashes. This approach fills a critical gap in planetary science, offering a groundbreaking way to uncover hidden insights in vast archives of remote-sensing data.

If an extraterrestrial civilization existed with technology similar to ours, would they be able to detect Earth and evidence of humanity? If so, what signals would they detect, and from how far away? Researchers used a theoretical, modeling-based method, and this study is the first to analyze multiple types of technosignatures together rather than separately. The findings revealed that radio signals, such as planetary radar emissions from the former Arecibo Observatory, are Earth’s most detectable technosignatures, potentially visible from up to 12,000 light-years away.

New research using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope reveals that planet formation can occur in harsh, high-radiation stellar environments. This contradicts earlier assumptions and suggests planet formation is more resilient than previously thought. The study observed protoplanetary disks within the Sigma Orionis cluster, finding structures indicating potential planet formation despite intense ultraviolet radiation from a nearby star. These findings expand our understanding of planetary formation and its prevalence throughout the galaxy, informing studies of our own solar system's origins. The high-resolution images obtained by ALMA were crucial to these discoveries.

Get ready to giggle and make bad jokes. Uranus is back in the news. In 1986, Voyager 2 flew by the distant ice giant and made a strange discovery—the planet's magnetic field was weird. It's not just weird; it's unlike every other planet in the solar system. For nearly 40 years, scientists have tried to understand why. To solve the mystery, researchers delved into the data collected by Voyager 2 and found a "cosmic coincidence". The solar wind was unusually strong just prior to the flyby, causing the strange observations. This is good news for Uranus's moons, which were thought to be inactive as a result of the Voyager 2 findings. Join planetary scientist Beth Johnson and space plasma physicist Jamie Jasinski from NASA's Jet Propulsion Laboratory as they discuss the initial observations, how the data was reevaluated, and what this all means for future missions to Uranus.

Imagine that scene from every apocalyptic asteroid movie—you know the one. The scientist comes rushing in because a "new" asteroid has been detected and is on a collision course with Earth. What happens next? The answer depends on several factors: how big is the asteroid, what is it made of, and how soon is the impact? (That's simplified but roll with it.) NASA's DART mission showed that an impactor can change the orbit of an asteroid, but that tested the hypothesis on the tiny moon of a small asteroid. What if the asteroid is much larger? Scientists at Sandia National Laboratories in New Mexico may have an answer -- a controlled nuclear blast that deflects (rather than destroys) the asteroid.

How to Kill an Asteroid with Dr. Robin George Andrews 42:21

28 weeks ago42:21

42:21

OSIRIS-REx and the Hayabusa spacecraft have sample asteroids to understand what they're made of. NASA sent the DART mission to change the orbit of a tiny asteroid orbiting another asteroid. ESA sent Hera as a follow-up mission to see what the impactor did. All of these missions have been done in the name of planetary defense -- protecting Earth from the worst of the rocks in space. While none of the asteroids so far discovered are a threat to our planet in the next century, there are still more out there that are small enough to do major damage to a city or even country. So what do we do if we find a near-Earth asteroid that's a real threat? Launch a team a la "Armageddon"? Ignore the problem? Try to flee off-planet or below ground? As DART showed, the best answer seems to be "move it out of the way". In his new book "How to Kill an Asteroid", Dr. Robin George Andrews tells the story of planetary defense and how we got to this point in saving ourselves.

Looking for Life in All the Wrong Places: The Atacama, NASA Viking Experiments, and Salts 26:50

26:50

In 1976, NASA's two Viking spacecraft touched down on Mars, becoming the first successful landers on the red planet. On board Viking 1, the craft carried several biological experiments to search for life. While most scientists consider the results of those experiments to be negative for Martian life, one experiment gave a positive result. The resulting controversy has spanned decades, with numerous scientists weighing in. Now, Dirk Schulze-Makuch from the Centre of Astronomy and Astrophysics (ZAA) at Technische Universität Berlin questions how those experiments were performed in light of what we know of extremely dry environments here on Earth. These Mars analogs, such as the Atacama desert in Chile, show that while microbes can survive in harsh conditions, too much water becomes a problem. And those Viking experiments may have involved too much water.

Naked Eye Comets? October May Yield a Bounty 37:02

34 weeks ago37:02

37:02

Comets are small objects in our solar system made of ice and dust. As they get closer to the Sun in their orbits, the ices turn into gas and give off a glow that can be seen in telescopes. With luck, that glow brightens to the point where a comet can be seen with the unaided eye. Some, like Halley's Comet, return on a regular schedule. Others are more one and done, breaking apart as they near the Sun or getting a gravity assist to leave our solar system. And every year, astronomers hope for the "comet of the century" -- a rare but visible comet that provides a show with a glorious coma and tail. This October, the observing community hopes that not just one but TWO recently discovered comets will put on that show. This week, Beth Johnson is joined by Dr. Ariel Graykowski, the Cometary Activity Lead for the SETI Institute and Unistellar citizen science project, to chat about the search for comets and the hope that either Comet C/2023 A3 Tsuchinshan-ATLAS or C/2024 S1 (ATLAS) will soon be visible to the unaided eye.

Exoplanets are planets that orbit stars outside our solar system. We've been finding potential exoplanets more often since the Kepler and TESS spacecraft were launched. But confirming these planets takes time, and telescope time is limited. To speed up the process, amateur astronomers are using their own telescopes. One program, called UNITE (Unistellar Network Investigating TESS Exoplanets), brings together a global group of volunteer and professional astronomers. They use Unistellar telescopes to gather data when exoplanets pass in front of their stars, blocking some of the light. Scientists from the SETI Institute and Unistellar analyze this data. Recently, they confirmed two exoplanets—a hot Jupiter and a warm sub-Saturn.
