A newly identified class of distant galaxies—nicknamed "little red dots"—may be doing something extraordinary: quietly creating the raw ingredients for life.

Join host Dr. Simon Steel as we explore groundbreaking new research from Dr. Remo Ruffini and Dr. Yu Wang from the International Center for Relativistic Astrophysics Network (ICRANet), suggesting that these compact, enigmatic galaxies could act as "molecular islands," forming complex organic molecules in environments surprisingly calm compared to the chaotic early universe.

- What makes these galaxies so special?
- How can such small, distant objects produce life's building blocks?
- And what does this mean for the possibility that life's chemistry is widespread across the cosmos?

We'll break down the science behind these "galactic oases," how they were discovered, and why they may reshape how we think about the origins of life in the universe.

Where should we actually be looking for life beyond Earth?

Astronomers have identified 45 Earth-like worlds that could be among the most promising places to search for biosignatures—chemical signs of life in distant atmospheres. Inspired by the idea of a real-life "Project Hail Mary," this research helps narrow the search for habitable planets and guides future telescopes toward the most compelling targets.

Join SETI Institute planetary astronomer Dr. Franck Marchis and guests Dr. Lisa Kaltenegger and Abigail Bohl from Cornell University as they explore:

- How scientists define an "Earth-like" world
- What makes a planet a strong candidate for life
- How these 45 planets were selected
- What telescopes, like the James Webb Space Telescope, can (and can't) detect
- What this means for the future of SETI and exoplanet exploration

Are we closer than ever to finding life—or just getting better at knowing where to look?

Join us for a special episode of SETI Live as host Lauren Sgro sits down with astronomer and entrepreneur Franck Marchis to explore the newly launched SkyMapper platform—now open to the public.

SkyMapper is a global, decentralized network of telescopes and all-sky sensors that connects professional observatories, citizen scientists, and classrooms around the world. In this live, interactive session, Lauren and Franck will go beyond the basics and show how SkyMapper works in real time—from navigating the interface and accessing live sky data to triggering observations and joining active discoveries.

We'll talk about what this launch means for the future of astronomy, how people are already using the platform, and why a continuously connected view of the sky could transform research, education, and public participation in science. We'll also highlight the SETI Institute's role in building this new global observing network.

✨ Ready to explore the universe yourself? This is your chance to see SkyMapper in action—and learn how to get involved.

Astronomers may have just witnessed the aftermath of a massive planetary collision in another star system—offering a rare glimpse into how worlds are destroyed… and possibly reborn.

Join host Dr. Moiya McTier and guest Anastasios Tzanidakis (University of Washington) as they break down new evidence suggesting that two large planetary bodies recently crashed into each other. What does this tell us about how planets form and evolve? How common are these catastrophic events? And could collisions like this help explain the chaotic early history of our own solar system?

From cosmic debris clouds to planetary recycling, we'll explore one of the most dramatic processes shaping worlds across the galaxy.

As NASA prepares to return humans to the Moon with Artemis II, what does it really take to live and work on the lunar surface?

Join host Simon Steel and planetary scientist Pascal Lee as they explore the science and strategy behind humanity's next giant leap. From cutting-edge spacesuit design and testing to the challenge of choosing where astronauts will land, this conversation dives into what comes next for lunar exploration.

We'll also explore:

- The mystery and importance of permanently shadowed regions
- Evidence for water ice on the Moon—and why it matters
- How Artemis is paving the way for future missions from the Moon to Mars

Artemis II is more than a mission—it's a proving ground for the future of human exploration.

How do scientists actually search for extraterrestrial intelligence?

Astronomer, professor, and Drake Award winner Jason Wright joins host Beth Johnson on SETI Live to discuss his new textbook, The Search for Extraterrestrial Intelligence: Theory and Practice. The book brings together the science, methods, and history of SETI into a single framework for students and researchers.

SETI has evolved dramatically in the past few decades—from early radio searches to modern investigations of technosignatures, including laser signals, infrared waste heat, and other possible evidence of advanced civilizations.

In this conversation, we explore:
Why SETI now deserves a full academic textbook
The many ways scientists search for alien technology
The history and philosophy behind the field
What would actually count as a real detection
How researchers are training the next generation of SETI scientists

Saturn's largest moon may have had a violent birth.

New research led by SETI Institute scientist Matija Ćuk proposes that Titan formed when two earlier Saturnian moons collided and merged hundreds of millions of years ago. This dramatic event may explain several long-standing mysteries in the Saturn system—including Titan's unusual orbit, the origin of the strange tumbling moon Hyperion, and even the relatively young age of Saturn's iconic rings.

Using computer simulations, researchers found that a once-stable Saturnian moon system may have become unstable, sending an outer moon on a collision course with Titan. The merger would have resurfaced Titan—erasing many ancient craters—and scattered debris that later formed Hyperion. The resulting changes to Titan's orbit could have destabilized smaller inner moons, triggering collisions that eventually created Saturn's rings.

Join SETI Institute Social Media Manager Beth Johnson and planetary dynamicist Matija Ćuk as they explore this new model for the Saturn system's evolution, what clues led scientists to propose a moon-moon merger, and how future missions—like NASA's Dragonfly mission to Titan—might test this dramatic hypothesis.

Could Titan really be the survivor of an ancient cosmic crash?

Astronomers have unveiled a novel technique for detecting faint signals from stellar and exoplanetary systems — potentially opening new pathways in the search for extraterrestrial technology and natural astrophysical phenomena alike.

In this episode of SETI Live, host Moiya McTier sits down with radio astronomer Cyril Tasse to explore the method described in Nature Astronomy. How does it work? Why is it different from traditional radio searches? And what kinds of signals could it reveal that we've been missing?

Radio waves from distant stars and planets are incredibly faint and often buried in noise. This new approach rethinks how we process and interpret complex data, potentially improving sensitivity to subtle, structured signals.
