Next #SETILive: When We Find Life
TODAY, 18 September, 11:00 am PDT
What happens after we discover life beyond Earth? The question is no longer “if,” but “when”—and how humanity responds could shape our future. Host and planetary astronomer Franck Marchis welcomes Martin Dominik, one of the authors of a new white paper on the societal, political, and philosophical challenges we’ll face once alien life is confirmed.

#ICYMI: Are we close to discovering life beyond Earth? Dr. Martin Dominik isn't certain, but he thinks we should be prepared to handle the consequences of finding that life. He spoke with Dr. Franck Marchis in this week's #SETILive. Watch the full interview: https://youtube.com/live/cULB0k2Cb7s
How do we find new trans-Neptunian objects, given that they are small and distant? Astronomer Dr. Rosemary E. Pike explains the necessary observations taken before, during, and after the expected place in the sky. Listen to the latest #SETILive #podcast: https://feeds.libsyn.com/462636/rss
Next #SETILive: Hidden Habitability on Ceres
Thursday, 2 October 2025, 2:30 pm PDT / 5:30 pm EDT
Join host Beth Johnson and guest Dr. Sam Courville, lead author of a new study on Ceres, as they dive into the possibility that the dwarf planet may have had the energy needed to support habitability for much longer than once believed. Could this small world in the asteroid belt have been more habitable than we ever imagined?

And that's a wrap! Our last #SETILive for the year has ended. We'll be back in 2025 with all new shows, guests, and science. Thank you for a wonderful 2024!
#ICYMI: The Kaçar Lab, led by Dr. Betül Kaçar at the University of Wisconsin-Madison, is challenging the assumptions about life as we know it, its origins, and its future. Beth chatted with Dr. Kaçar in this week's #SETILive, and wow, we all learned a lot! Watch the full interview: https://youtube.com/live/hLw4olNyBng
Next #SETILive: A Cookbook of Life
TODAY, Thursday, May 15, 2025 12:00 PM PDT
Join Beth Johnson as we explore groundbreaking research from the University of Wisconsin–Madison. 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.

In a new study using #JWST, scientists have discovered a hidden population of tiny asteroids in our solar system. These objects might be a more significant threat than we ever realized.
In a recent #SETILive episode, Senior Planetary Astronomer Dr. Franck Marchis and the study's lead authors, Dr. Artem Y. Burdanov and Dr. Julien de Wit, discussed the role of minor asteroids and what they can reveal about potential threats to Earth.

No new #SETILive #podcast this week, so let's go back to April 1 and an interesting exoplanet called HD 20794 d with an eccentric orbit. The temperature differences make it a great place to study a planet's potential habitability!
