Saturn's rings are so young that they may have formed when dinosaurs walked the Earth. Richard Durisen, a Professor Emeritus of Astronomy from Indiana University Bloomington, and Paul Estrada, a Research Scientist at NASA Ames Research Center, join Planetary Radio to discuss their research on the surprisingly recent formation of Saturn's rings and why they are disappearing over time. Then Bruce Betts and host Sarah Al-Ahmed share what's in the upcoming night sky and chat about creepy-crawly constellations.

Every major NASA center built after the agency’s inception is located in the American South. Why? Dr. Brian Odom, NASA’s chief historian, joins the show to explore the relationship between NASA and the South, how politics and geography led to this focus, and why NASA’s expansion during the Apollo era was likened to a second reconstruction of a previously rural and underdeveloped region of the United States.

Space Policy Edition: NASA and the American South

Scientists have discovered over 5,500 exoplanets, but they’re just getting started. We dive into the stunning variety of exoplanets beyond our Solar System with Jessie Christiansen, the project scientist for the NASA Exoplanet Archive. But first, The Planetary Society's science editor, Asa Stahl, shares more about the upcoming Habitable Worlds Observatory, a cutting-edge space telescope designed to hunt for worlds that could harbor life. We also give an update on the International Space Station with our senior communications advisor, Mat Kaplan. Stick around for What's Up with Bruce Betts as we discuss the advances in exoplanet detection and share a new Random Space Fact.

Every year on June 30, the space community observes Asteroid Day, the anniversary of the Tunguska blast. Markus Payer, Asteroid Foundation Chair, joins us to talk about this year's Asteroid Day festivities. We also get an update on the results of the Double Asteroid Redirection Test (DART) with Terik Daly, a planetary scientist and the Planetary Impact Laboratory manager at Johns Hopkins Applied Physics Lab. He’ll tell us more about the aftermath of DART’s smashing encounter with asteroid Dimorphos. Then Bruce Betts, our chief scientist, discusses what The Planetary Society’s asteroid-hunting grant winners have been up and in What's Up.
