A deeply eroded giant volcano, active from ancient through recent times and with possible remnants of glacier ice near its base, had been hiding near Mars’ equator in plain sight. Its discovery points to an exciting new place to search for life, and a potential destination for future robotic and human exploration. “We were examining the geology of an area where we had found the remains of a glacier last year when we realized we were inside a huge and deeply eroded volcano,” said Dr. Pascal Lee, planetary scientist with the SETI Institute and the Mars Institute based at NASA Ames Research Center, and the lead author of the study announced at the 55th Lunar and Planetary Science Conference held in The Woodlands, Texas. Sourabh Shubham, a graduate student in the Department of Geology at the University of Maryland, is co-author of the discovery. Join Dr. Lee as he talks with communications specialist Beth Johnson about the recent discovery and its potential impact on the search for life beyond Earth. (Recorded 11 April 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.

The TRAPPIST-1 planetary system has fascinated both scientists and the public since the discovery of the last five of its seven terrestrial worlds in 2017. With four of those planets in the so-called habitable zone, where water can be liquid, the system has become a favorite target of ground- and space-based telescopes alike, especially with regard to the potential for harboring life. However, TRAPPIST-1 is a red dwarf star, cooler and smaller than our own Sun, leading to concerns about the ability of these tidally locked worlds to develop and maintain their own atmospheres. Now, in new research published in The Astrophysical Journal, a team of researchers has discovered that TRAPPIST-1e's atmosphere is being stripped by strong electric currents, quashing some hopes that the world is habitable. Communications specialist Beth Johnson is joined by co-author Dr. Cecilia Garraffo from the Harvard-Smithsonian Center for Astrophysics to talk about this disappointing news and its impact on the search for life beyond Earth, as well as her work in establishing AstroAI, "a cutting-edge research institute dedicated to advancing astrophysics through the application of artificial intelligence."

Only eight times in history have scientists found an asteroid, tracked its trajectory toward Earth, and caught the resulting fireball on cameras. The latest of these eight events happened in January 2024, with the discovery of asteroid 2024 BX1, a mere three hours before impacting the atmosphere over Europe. And of course, the SETI Institute's own Dr. Peter Jenniskens was hot on the trail, flying to Germany to help search for meteorite fragments. Within the week, several pieces were discovered, and early analysis found that they belong to a rare group of meteorites called "aubrites". Join communications specialist Beth Johnson as she chats with Dr. Jenniskens about this search, the resulting find and its implications, and prior work hunting for meteorites around the world.

Throughout human history, comets have fascinated us. They have gone from signs and portents of bad things to come to well-studied and even visited "dirty snowballs". Every year, observers search the skies, hoping to discover the Next Big Comet - Halley, Hyakutake, Hale–Bopp, McNaught. From SOHO and LINEAR to ATLAS and IRAS, numerous observatories have continued to add to the count of discovered comets. But it doesn't require expensive hardware or spacecraft to make similar observations from your own backyard; telescopes and even binoculars will work - at least for the brightest objects. For members of Unistellar's Citizen Science Network, however, comets can be seen at faint magnitudes under a range of night sky conditions. Join Beth Johnson as she welcomes SETI Institute Postdoctoral Fellow Ariel Graykowski to this week's SETI Live to discuss the results of citizen scientist observations of comets 12P/Pons-Brooks and C/2023 A3 (Tsuchinshan-ATLAS).

Join us for an exciting SETI Live where we’ll explore the wonders beyond Earth. We’re excited to have Valery Lainey, a renowned researcher from the Paris Observatory in France, as our guest. 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. (Recorded 8 February 2024.)

In a groundbreaking cosmic quest, the SETI Institute’s Commensal Open-Source Multimode Interferometer Cluster (COSMIC) at the Karl G. Jansky Very Large Array (VLA) is expanding the search for extraterrestrial intelligence (SETI). This cutting-edge technology is not a distinct telescope; it’s a detector. COSMIC searches for extraterrestrial signals and paves the way for future science using a copy of the raw data from the telescope’s observations. At the heart of COSMIC’s mission is pursuing the age-old question: Are we alone in the universe? Project scientist Dr. Chenoa Tremblay and the team detailed the project in a paper published in The Astronomical Journal. At the American Astronomical Society's winter 2024 conference in New Orleans, Simon Steel, Deputy Director of the Carl Sagan Center, interviewed Dr. Tremblay about the project and its mission.

NASA’s Juno mission has observed mineral salts and organic compounds on the surface of Jupiter’s moon Ganymede. Data for this discovery was collected by the Jovian InfraRed Auroral Mapper (JIRAM) spectrometer aboard the spacecraft during a close flyby of the icy moon. The findings, which could help scientists better understand the origin of Ganymede and the composition of its deep ocean, were published on Oct. 30 in the journal Nature Astronomy. Federico Tosi, a Juno co-investigator from Italy’s National Institute for Astrophysics in Rome and lead author of the paper, speaks with senior astronomer Franck Marchis about this discovery and what it could mean for Ganymede's subsurface oceans and possibly life.

Critically acclaimed, bestselling authors Kelly and Zach Weinersmith (Saturday Morning Breakfast Cereal) set out to write the essential guide to a glorious future of space settlements, but after years of research, they aren’t so sure it’s a good idea. Space technologies and space business are progressing fast, but we lack the knowledge needed to have space kids, build space farms, and create space nations in a way that doesn’t spark conflict back home. In a world hurtling toward human expansion into space, A City on Mars investigates whether the dream of new worlds won’t create nightmares, both for settlers and the people they leave behind. With deep expertise and a winning sense of humor, the Weinersmiths investigate perhaps the biggest questions humanity will ever ask itself—whether and how to become multiplanetary. Join them in a special conversation with SETI Institute's Beth Johnson.

Join us for an exclusive SETI Live event, as we take a first look at the next-generation telescope from Unistellar - the ODYSSEY. First introduced in 2017 with their eVscope, Unistellar has been a prominent collaborator with the SETI Institute since 2019. eVscopes have been used by schools, colleges, and the public to observe exoplanets, supernovae, and asteroids in a truly global network that continues to grow. Simon Steel, Deputy Director of the Carl Sagan Center, and Franck Marchis, Co-founder of Unistellar and citizen science director at the SETI Institute, will talk about the technology of the new telescope, insights on how such a telescope is beta tested, and how the ODYSSEY will dramatically impact citizen and amateur astronomer’s contribution to cutting edge scientific research. We’ll take a tour of this beautiful instrument, inside and out, and look at some early results and images. (Recorded 10 January 2024.)

In a new study published in the Astronomical Journal, researchers used the known population of exoplanets to set better thresholds for planetary effects on signals from ETIs (extraterrestrial intelligences). Megan Grace Li, a Ph.D. student at UCLA in UCLA SETI, conducted this research as a National Science Foundation Research Experience for Undergraduates intern in the Breakthrough Listen project at the Berkeley SETI Research Center. Join Megan as she chats with Beth Johnson about her work and what it means for the future of SETI searches. (Recorded 30 November 2023.)

On Earth, we understand how and where earthquakes happen due to the discovery of plate tectonics – the continental crust’s creation, movement, and destruction. However, when astronauts placed seismometers on the lunar surface during NASA’s Apollo mission era, those instruments recorded quakes on the Moon. In the 1970s, the Viking landers also recorded quakes on the surface of Mars. Since neither of these worlds has plate tectonics, scientists set about collecting more data to understand the phenomena, which led to the recent NASA InSight lander. Now, a new paper in Geophysical Research Letters explains how the largest recorded seismic event on Mars provided evidence for a different sort of tectonic origin — the release of stress within the Martian crust. Join communications specialist Beth Johnson as she talks to lead author Benjamin Fernando about the results of an amazing international collaboration that led to this new discovery.
