Space is the Case: A Conversation with SETI Artist in Residence Martin Wilner
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.

Looking for Lunar Anomalies Using Automated Methods
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.

Earth Detecting Earth: How Far Away Can We Detect Earth's Technosignatures?
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. Join Simon Steel, Deputy Director of the Carl Sagan Center, for a chat with lead author Sofia Sheikh about the research's findings and their implications for the search for technosignatures.

Unistellar + SETI: Citizen Science Q&A (Part 5)
Join Dr. Franck Marchis, Chief Science Officer and co-founder at Unistellar and director of Citizen Science at SETI Institute, 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 review the 2024 citizen science accomplishments and discuss the 2025 campaigns so far. We will answer your questions about our program from the Unistellar community page and discuss some recent highlights. (Recorded 6 February 2025.)

Planets Form Where?? ALMA Observations Show Planet Formation in Harsh Environments
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. Join communications specialist Beth Johnson for an interview with lead author Dr. Jane Huang about this new research, its impact on understanding our solar system, and how it relates to the search for habitable worlds. (Recorded 23 January 2025.)
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.
