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.)

​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.

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. Join planetary astronomer Franck Marchis and lead author Nicola Nari for a discussion on the search for exoplanets, what a habitable world could look like, and how HD 20794 d will help us understand our universe. (Recorded live 20 March 2025.)

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. (Recorded live 27 February 2025.)

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. Join senior planetary astronomer Franck Marchis as he chats with authors Adam Lesnikowski and Daniel Angerhausen about this revolutionary method and its implications for future discoveries.

Nearly 40 years ago, on November 20, 1984, the SETI Institute was incorporated with inaugural officers CEO Thomas Pierson and SETI scientist Jill Tarter. The goal was to provide SETI researchers with a place to grow the search for life beyond Earth. What began with one NASA-funded SETI project and two people has since grown to include over 100 researchers and various scientific areas of study, all seeking to understand the origins and prevalence of life and intelligence in the universe. As a part of our outreach and education efforts, we grew our presence on the Internet, reaching out to a wide audience through our website, social media, and livestreams like SETI Live. We have education programs across all age ranges. We produce the weekly podcast Big Picture Science. And today, we celebrate all of these accomplishments and look forward to the next 40 years of science. Join host and senior planetary astronomer Franck Marchis as he chats with SETI Institute President and CEO Bill Diamond, senior astronomer and Big Picture Science co-host Seth Shostak, long-time Board of Directors member Andrew Fraknoi, and the Director of the Carl Sagan Center Nathalie Cabrol. (Recorded live 14 November 2024.)

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. Join Dr. Franck Marchis as he discusses Dr. Schulze-Makuch's recent Nature Astronomy article and how we should follow the salts instead of the water. (Recorded 28 October 2024.)

Scientists now can work out what the atmospheres of worlds outside our solar system are made of. Using the James Webb Space Telescope, we have seen water, carbon dioxide, methane, and other gases. Could we, from this distance, know how those gases formed? Possibly. Looking for planets with signs of being intentionally changed - terraforming - would give us proof of an advanced civilization, and a new paper explores just how the investigation process would work. Senior astronomer Franck Marchis talks with authors Edward W. Schwieterman and Daniel Angerhausen about what these gases would be and why they would work as evidence of life. (Recorded 28 August 2024.)

When scientists found the first exoplanets over 30 years ago, the discovery defied all expectations. In the following decades, with the advent of NASA's Kepler and TESS missions and numerous ground-based observatories, the exoplanet count has risen to nearly 6,000 confirmed worlds and some 7,200 candidates. Press releases on newly confirmed planets tend to be about exciting or strange places, and this week's SETI Live is no exception. Discovered in TESS data, Gliese 12 b is a recently confirmed exoplanet the size of Earth or Venus, orbiting a red dwarf star every thirteen days and "only" about 40 light-years away from our solar system. This close-in, rocky world could potentially be studied using the JWST for more precise information on its size and atmospheric composition (if there is an atmosphere). Two separate teams of researchers confirmed the planet, and today, senior planetary astronomer Franck Marchis is joined by the two lead authors from one of those teams - Shishir Dholakia, a doctoral student at the Centre for Astrophysics at the University of Southern Queensland in Australia, and Larissa Palethorpe, a doctoral student at the University of Edinburgh. Join Franck, Shishir, and Larissa in what promises to be an interesting conversation about Gliese 12 b's discovery, confirmation, and potential for understanding planetary formation and evolution. (Recorded 27 June 2024.)

In 2023, scientists analyzed archival data from NASA's Magellan mission, which mapped the surface of our "twin" planet, Venus. They discovered evidence of a recent volcanic eruption on the world's surface by comparing the Magellan images over time. Now, a team of Italian scientists has found evidence for two more eruptions during Magellan's observations. Published in Nature Astronomy, this new research could help us understand why Venus took a different path in planetary evolution and provides some follow-up questions for the upcoming VERITAS mission. Join senior planetary astronomer Franck Marchis as he chats with lead author Davide Sulcanese of d'Annunzio University in Pescara, Italy, about this remarkable new work and what it means for future studies of Venus. (Recorded 20 June 2024.)

A potential future space mission known as the Large Interferometer for Exoplanets (LIFE) could study terrestrial worlds in their stars' habitable zones (where water can be liquid) using spectral emissions in the mid-infrared. With only one known example of a world with life - Earth - scientists recently examined whether or not such a mission could determine if a planet was habitable. Published in The Astrophysical Journal, the results of a recent study concluded that yes, LIFE could find "signatures of crucial atmospheric species and [detect] the planet's temperate climate as well as surface conditions allowing for liquid water." Co-author Björn S. Konrad joins senior planetary astronomer Franck Marchis from ETH Zurich for an engaging SETI Live on how they used remote sensing data to draw their conclusions and what the results mean for the search for life beyond Earth.

Recorded 8 February 2024. Join us for an exciting SETI Live where we'll explore the wonders beyond Earth. We're excited to have Dr. Valéry Lainey, a renowned researcher from the Paris Observatory in France, as our guest. Dr. Franck Marchis, our Senior Astronomer, will be guiding the conversation, sharing insights from the universe. It's set to be an engaging event, and we hope you'll be part of it!   In a groundbreaking study published in Nature Journal, Valery Lainey and his team have unveiled a remarkable discovery about Saturn's moon Mimas. Once thought to be a cold, solid body of ice and rock, Mimas now appears to harbor a vast global ocean beneath its icy crust. This revelation comes after a meticulous analysis of Mimas's orbit, as observed by NASA's Cassini spacecraft, which showed unexpected wobbles that suggest the presence of an under-ice ocean.   For years, the scientific community was skeptical about the possibility of an ocean within Mimas, mainly because the expected surface deformations were absent. However, Lainey's research, based on recent simulations and precise orbital measurements, suggests that an ocean could exist without leaving visible marks on the moon's surface. This finding not only reshapes our understanding of Mimas but also opens new avenues in the search for habitable environments beyond Earth.    Press release: https://www.newscientist.com/article/2416084-saturns-moon-mimas-may-be-hiding-a-vast-global-ocean-under-its-ice/   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!

Recorded live on 28 September 2023. The Apollo missions showed scientists that the craters on the Moon were from impacts rather than volcanoes, overturning previously held hypotheses. Now, new research using data collected by China's Chinese Chang'E 1 and 2 orbiters has discovered a hot spot under the surface. Using an instrument that made observations at microwave wavelengths, the team mapped out temperatures and found one particular suspected volcano, known as Compton-Belkovich, glowed in the microwave.    However, surface evidence shows the volcano last erupted about 3.5 billion years ago, and the heat is coming from radioactive elements in the solid rock. That radioactivity led scientists to conclude that under the surface lies a large chunk of granite - magma that cooled underground - providing evidence for the most Earth-like volcanism found on the Moon to date.   Join planetary astronomer Dr. Franck Marchis as he discusses these interesting new findings with lead author Dr. Matt Siegler, Senior Scientist at the Planetary Science Institute.  Press release:  https://www.psi.edu/blog/evidence-of-new-volcanic-process-on-moon-discovered-pr/   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!

From Nov 21, 2023. Hosted by Dr. Franck Marchis. Up until now, the quest to find evidence of active volcanism on other worlds has been limited to our own solar system. We've definitively seen volcanoes erupting on Jupiter's moon, Io; we've possibly found evidence of geologically recent volcanism on Venus; and Mars has the largest volcano, although dormant, in Olympus Mons. With the advent of the JWST era, however, more possibilities have opened up. Colby Ostberg is an astronomer at UC Riverside and the lead author of an intriguing recent study on terrestrial exoplanet atmospheres and their potential volcanic activities, focusing on the direct imaging of such exoplanets.   Dr. Marchis and Colby discuss the results of the article, including the implication of volcanic activity on the color of an exoplanet and its atmospheric composition. Discover the future of exoplanetary science, where we're heading in our quest to understand these distant worlds, and how advances in technology and telescopic observations are bringing us closer to answers.

Recorded live 24 August 2023. An enigmatic cosmic entity has been consistently beaming radio waves to Earth every 22 minutes for over three decades, perplexing the scientific community. Identified as GPM J1839−10, this celestial body is believed to be a fading star emitting energy from its poles.    Yet, intriguingly, its spin is so leisurely it seems implausible for its existence, marking it both incredibly stable and unusually slow. We're thrilled to have Dr. Natasha Hurley-Walker, the leading radio astronomer from Curtin University in Australia, who spearheaded the research in conversation with the SETI astronomer and Chief Scientific Officer at Unistellar, Dr. Franck Marchis.    Together, they'll delve into this baffling find, initially spotted in archival data from 1988 and later confirmed through 2022 observations using the MeerKAT array. Could this star be something new? Maybe it changes what we think we know about other stars.

Led by Anicia Arredondo, researchers used the Stratospheric Observatory for Infrared Astronomy (SOFIA) to investigate the metallic nature of the asteroid Psyche, believed to be rich in metals. SOFIA observed the entire surface of Psyche, using mid-infrared instruments to analyze its emissivity and porosity. The results confirmed that Psyche is a metallic body with some differences between the northern and southern poles. This study paves the way for NASA's mission to Psyche, launching in October 2023, promising insights into planetary cores and planet formation. Psyche's size and potential for differentiation make it a significant subject for understanding Earth-like planets. Join Anicia and SETI Institute senior astronomer Franck Marchis to learn more!

Up until now, the quest to find evidence of active volcanism on other worlds has been limited to our own solar system. We've definitively seen volcanoes erupting on Jupiter's moon, Io; we've possibly found evidence of geologically recent volcanism on Venus; and Mars has the largest volcano, although dormant, in Olympus Mons. With the advent of the JWST era, however, more possibilities have opened up. Colby Ostberg is an astronomer at UC Riverside and the lead author of an intriguing recent study on terrestrial exoplanet atmospheres and their potential volcanic activities, focusing on the direct imaging of such exoplanets. Dr. Franck Marchis and Colby discuss the results of the article, including the implication of volcanic activity on the color of an exoplanet and its atmospheric composition. Discover the future of exoplanetary science, where we're heading in our quest to understand these distant worlds, and how advances in technology and telescopic observations are bringing us closer to answers.

Recorded live 13 July 2023. Hosted by Dr. Franck Marchis. If an alien civilization wanted to communicate with other civilizations throughout the Milky Way, the galaxy's core holds potential as a strategic site for a beacon. Until now, radio SETI has primarily dedicated its efforts to the search for continuous signals. A new study sheds light on the remarkable energy efficiency of a train of pulses as a means of interstellar communication across vast distances. This marks the first-ever comprehensive endeavor to conduct in-depth searches for these signals. Join us in discussion with Dr. Vishal Gajjar, a SETI Institute astronomer working at the Allen Telescope Array.

The Apollo missions showed scientists that the craters on the Moon were from impacts rather than volcanoes, overturning previously held hypotheses. Now, new research using data collected by China's Chinese Chang'E 1 and 2 orbiters has discovered a hot spot under the surface. Using an instrument that made observations at microwave wavelengths, the team mapped out temperatures and found one particular suspected volcano, known as Compton-Belkovich, glowed in the microwave. However, surface evidence shows the volcano last erupted about 3.5 billion years ago, and the heat is coming from radioactive elements in the solid rock. That radioactivity led scientists to conclude that under the surface lies a large chunk of granite - magma that cooled underground - providing evidence for the most Earth-like volcanism found on the Moon to date. Join planetary astronomer Franck Marchis as he discusses these interesting new findings with lead author Matt Siegler, Senior Scientist at the Planetary Science Institute.

Who hasn't looked up at the stars at some point and thought maybe there are other intelligent creatures out there? Astronomers scan the cosmos and they've found plenty of intriguing but inconclusive signals so far. Are they no more than magnetic waves from far off dead planets, or something more?

In this week's Bunker Gold we revisit an out of this world episode from May 2022… As scientists seek extraterrestrial life, what would we do if we actually found it? How would we manage first contact, and could we even communicate with aliens? Franck Marchis, a senior planetary astronomer from the SETI Institute, unpacks the prospect with Andrew Harrison – and the idea aliens might already know we're here, but we're too boring for them to care. “The most important question is intelligent life.” “This discovery will not be a big surprise for a lot of humans on this planet.” “If we find a civilisation slightly more advanced to us, maybe 100 years, they may be much more intelligent in terms of technology.” “We may not see them because perhaps their technology is invisible to us.” Support us on Patreon: https://www.patreon.com/bunkercast Written and presented by Andrew Harrison.

An enigmatic cosmic entity has been consistently beaming radio waves to Earth every 22 minutes for over three decades, perplexing the scientific community. Identified as GPM J1839−10, this celestial body is believed to be a fading star emitting energy from its poles. Yet, intriguingly, its spin is so leisurely it seems implausible for its existence, marking it both incredibly stable and unusually slow. We're thrilled to have Natasha Hurley-Walker, the leading radio astronomer from Curtin University in Australia, who spearheaded the research in conversation with the SETI astronomer and Chief Scientific Officer at Unistellar, Franck Marchis. Together, they'll delve into this baffling find, initially spotted in archival data from 1988 and later confirmed through 2022 observations using the MeerKAT array. Could this star be something new? Maybe it changes what we think we know about other stars. Or could it be a signal from aliens?  Record live 24 August 2023. Paper: https://www.nature.com/articles/s41586-023-06202-5

We will present the first on-sky demonstration of the Fibered Imager foR a Single Telescope (FIRST) instrument at the Subaru Telescope. Using techniques of aperture masking and spatial filtering, FIRST combines the power of spectro-interferometry to deliver high contrast capabilities and spatial resolutions beyond the reach of traditional coronagraphic instruments. We will explain the 'pupil remapping' technique - the heart of the FIRST instrument - and its practical applications. This process divides the telescope pupil into sub-pupils, enabling simultaneous measurements of all baseline fringe patterns. Our researchers tested this instrument on two types of targets: a point source (Keho'oea - α Lyrae) and a binary system (Hokulei - α Aurigae), achieving a contrast and stability sufficient to study the close surroundings of those stars. The successful demonstration of FIRST signifies a significant step forward for future interferometric instrumentation on extremely large telescopes, opening new observing capabilities in the visible wavelength range at the Subaru Telescope. With the SETI Institute's Franck Marchis and Sebastien Vievard, exoplanet instrumentation scientist on SCExAO. Recorded live 20 July 2023

The search for life beyond Earth received a slight boost from new research published in Nature this month. Scientists working with data collected by NASA's Cassini mission to Saturn discovered evidence of phosphates in ice particles ejected via cryovolcanism into the E-ring structure by the tiny moon Enceladus. Although a mere 500 kilometers in diameter, Enceladus is a huge target in the quest for astrobiology in our solar system as beneath the outer ice shell lies a subsurface ocean about 10 km deep. That ocean is warmed via tidal heating, and plumes of water vapor escape through cracks in the surface. Enter the Cassini mission, which spent over 13 years orbiting Saturn, collecting data on the gas giant, the rings, and various moons, including Enceladus. The spacecraft even flew through the plumes, using instruments such as the ion and neutral mass spectrometer (INMS) and the cosmic dust analyzer (CDA) to directly sample the material. Over the years, five of the six elements considered to be the building blocks for life as we know it - carbon, hydrogen, nitrogen, oxygen, and sulfur - have been found within those ice grains. The recent discovery of the sixth element, in the form of phosphates, not only completes the set but provides an ingredient necessary for the creation of DNA and RNA. While the discovery is not evidence of life on Enceladus, the potential for life in that subsurface ocean continues to grow. Please join lead author Frank Postberg, a planetary scientist at Freie Universität Berlin, and SETI Institute senior scientist Franck Marchis as they discuss the impact of this discovery, the deeper meaning for the search for life beyond Earth, and what's next for the research.

Using data from NASA's Hubble and Spitzer Space Telescopes, researchers at the University of Montreal found evidence that two exoplanets orbiting a star 218 light-years away are “water worlds,” where water makes up a large fraction of the entire planet. These planets are unlike planets in our solar system -- they were previously believed to be rocky Earth-like planets but instead are really water worlds. Listen to Franck Marchis in conversation with lead researcher Caroline Piaulet to learn about these new findings.

We have to admit that 2022 was an impressive year for space science, what with JWST starting to collect science data and even releasing early results, the launch and return of the Artemis 1 mission, the DART mission, a NASA Juno flyby of Europa, and the end of the NASA InSight lander mission. And that was just NASA's part of the activity! China, Japan, and South Korea all launched missions, while commercial launches and space tourism continued to increase. 2023 is definitely shaping up to match. There are more potential mission launches for NASA, ESA, China, India, and Japan; a total solar eclipse; a sample return; more Juno flybys; and even a comet or two that can be seen with the unaided eye. Join SETI Institute senior scientist Franck Marchis and communications specialist Beth Johnson as they take a look at what's in store for the new year. Recorded live 4 January 2023.

Franck Marchis is a SETI (Search for Extraterrestrial Intelligence) senior planetary astronomer and chair of the exoplanet group at the Carl Sagan Center of the SETI Institute. Prior to this, his work has involved the discovery and characterisation of numerous asteroids, study of the volcanism on Io (one of Jupiter's moons) and the enhancement of adaptive optics. He is also the co-founder of Unistellar, a company that develops extremely high quality telescopes. To find out more, visit http://franckmarchis.com/ or https://unistellaroptics.com/. "We are a young technological intelligent civilization and we are like teenagers. We've only recently learned what we can do and how great life can be." To start off today, Konner and Franck chat about his origins, his studies of Io, the aversion of physical activity within academia, as well as the importance of branching out into other fields and travel for all of us. But around 30 minutes in, the guys begin talking about what all good discussions around astronomy eventually get to, which is aliens. They discuss some actual SETI findings, such as the staggering number of planets out there that could be harbouring life. We talk about the philosophy of alien life, how that might affect humanity, and finally, what it could be like if humanity became a space faring civilization.
