SETI Live is a weekly production of the SETI Institute and is recorded live on stream with viewers on YouTube, Facebook, LinkedIn, X (formerly known as Twitter), and Twitch. Guests include astronomers, planetary scientists, cosmologists, and more, working on current scientific research. Founded in 1984, the SETI Institute is a non-profit, multi-disciplinary research and education organization whose mission is to lead humanity’s quest to understand the origins and prevalence of life and intelligence in the Universe and to share that knowledge with the world.

    Life in Titan’s Ocean? The Microscopic Possibility of Biomass on Saturn's Moon

    Saturn’s largest moon, Titan, is a world of methane rivers and lakes, icy boulders, sandy dunes, and a vast subsurface ocean. Could this distant world harbor life? A new study led by Dr. Antonin Affholder, now a fellow at ETH Zurich, suggests that Titan’s ocean might support life—but only in the tiniest amounts, making it incredibly hard to find. Join communications specialist Beth Johnson as she chats with Dr. Affholder to explore what this means for the search for life beyond Earth, why organics on Titan may not provide enough fuel, and how NASA’s Dragonfly mission might help answer these questions.

    LaserSETI Live Puerto Rico Edition: A New Observatory & Revisiting the Wow! Signal

    Join us for a special livestream featuring Dr. Abel Méndez from the University of Puerto Rico at Arecibo, hosted by SETI Institute researcher Dr. Lauren Sgro. They will discuss the latest on LaserSETI, the all-sky project searching for optical technosignatures, including exciting updates from the new installation in Puerto Rico. This special “LaserSETI Live” will also dive into Méndez’s new study on the legendary Wow! Signal, in which he and his team revisit one of the most intriguing mysteries in the search for extraterrestrial intelligence with fresh analysis and new insights. This event connects Puerto Rico’s rich legacy in radio astronomy with today’s cutting-edge search for signals of life beyond Earth, so don’t miss this livestream! (Recorded live 30 August 2025.)

    Pulsing White Dwarf! Decoding a Strange Radio Rhythm

    Join us for a 30-minute livestream with Simon Steel, Deputy Director of the Carl Sagan Center for Research at the SETI Institute, and Dr. Sanne Bloot, lead author of a recent study published in Astronomy & Astrophysics. They will discuss one of the universe’s most puzzling new discoveries: a white dwarf that emits highly polarized radio pulses in a strange, patterned rhythm. (Recorded live 28 August 2025.)

    Can We Recognize Alien Life? Ocean Worlds and the Search for Life

    Join communications specialist Beth Johnson for a conversation with Dr. Anastasia Yanchilina, Frank Drake Postdoctoral Fellow at the SETI Institute, as we explore how life might emerge and/or be mistaken for in environments beyond Earth. Dr. Yanchilla studies abiotic mineral structures, or “chemical gardens,” that resemble biological life but form entirely through non-living processes. By recreating these systems under conditions similar to hydrothermal vents on ocean worlds such as Enceladus and Mars, she investigates how to distinguish between life and non-life, and what this means for the origin of life on Earth. We’ll discuss how minerals, organics, and even UV light interact in these experiments, and how this research helps us refine the search for biosignatures across the solar system.

    Citizen Science in Astronomy (Part 7): Comet 3I/ATLAS and a Disintegrating Exoplanet

    Join Dr. Franck Marchis, Director of Citizen Science at the SETI Institute, Chief Science Officer and co-founder of Unistellar, and co-founder and Chief Executive Officer of SkyMapper, and Dr. Lauren Sgro, Outreach Manager at the SETI Institute, for a conversation on citizen science with the Unistellar network in partnership with the SETI Institute. We will talk about amateur astronomer observations of Comet 3I/ATLAS, a disintegrating exoplanet, asteroid (762) Pulcova, and the satellite Tanager. We will also answer your questions about our program from the Unistellar community page and discuss recent highlights. (Recorded live 14 August 2025.)

    Closest Exoplanet Yet? JWST Reveals Neighboring Planet Candidate

    Join astronomers Franck Marchis (SETI Institute) and Julien Girard (Space Telescope Science Institute) for a 30-minute live discussion unpacking NASA’s exciting new findings from JWST. Just announced, JWST has revealed strong evidence of a Saturn-mass gas giant orbiting Alpha Centauri A—the Sun’s nearest solar twin—located just 4 light-years away. The planet appears to orbit at about 1 to 2 AU, placing it within the star’s habitable zone, though as a gas giant, it's not likely habitable itself. (Recorded live 8 August 2025.)

    Orbital Oddity and Neptune: Resonant Object Hints at Planetary Migration

    Join us for a 30-minute live conversation with astronomer Dr. Rosemary E. Pike, lead author of a groundbreaking new study that reveals the discovery of a rare and distant object orbiting in resonance with Neptune. Hosted by Beth Johnson of the SETI Institute, this stream will explore the science behind this unusual trans-Neptunian object, what it tells us about the early solar system, and why its orbital alignment is so surprising.

    A Vaporizing Planet: Why BD+05 4868 b is Turning to Dust

    Join communications specialist Beth Johnson for a live interview with astrophysicist Marc Hon (MIT), lead author of a new study revealing one of the most extreme exoplanets ever discovered — a small, rocky world that's literally disintegrating as it orbits its star. BD+05 4868 b is a Mercury-sized planet just 140 light-years away that’s orbiting so close to its star, it’s roasting at around 1650°C. The heat is intense enough to vaporize the planet’s rocky surface, creating a massive comet-like tail of mineral dust stretching millions of kilometers across space. This rare discovery — only the fourth known disintegrating planet — offers scientists an unprecedented opportunity to study the geology of an alien world, and upcoming JWST observations could even reveal the chemical makeup of its interior.
