We have begun to understand the composition of worlds that are hundreds of trillions of kilometers from Earth. Astronomer Nikole Lewis is co-leader of a team that has used the Hubble Space Telescope to do this with the four Earth-like planets circling a star called TRAPPIST-1. Host Mat Kaplan talks with Digital Editor Jason Davis about a new probe designed to discover thousands of additional exoplanets.  Want to win a Planetary Radio t-shirt?

Visiting the Earth-Like Worlds of TRAPPIST-1

On April 8, 2024, a total solar eclipse passed over Mexico, the United States, and Canada. This week on Planetary Radio, we take a trip to The Planetary Society’s Eclipse-O-Rama festival in Fredericksburg, Texas, where hundreds gathered to witness totality. We share the reactions of festival attendees along with snippets from the talks given by special guests at the event, including Bill Nye, the CEO of The Planetary Society, Bethany Ehlmann, president of The Planetary Society and principal investigator for the NASA Lunar Trailblazer mission, and Bee Hayes-Thakore, Vice President of Marketing at Kigen and member of The Planetary Society's board of directors. Tim Dodd, better known as the Everyday Astronaut, and Bob Pflugfelder, popularly known as Science Bob, share their experiences. Bruce Betts, the chief scientist of The Planetary Society, tells us about the solar features people may have seen during the eclipse in What's Up. Then we get an update on the Mars Sample Return mission with Casey Dreier, The Planetary Society's chief of space policy, and Jack Kiraly, our director of government relations.

Eclipse-O-Rama

This week on Planetary Radio, we explore "The Lost Universe," NASA's first tabletop role-playing game, with Christina Mitchell, a senior multimedia specialist at NASA's Goddard Space Flight Center in Maryland, U.S.A. Then, we'll shift our gaze from the mythical to the methodical with Amaury Triaud, an astronomer from the University of Birmingham in the U.K. He and his colleagues have found a new method for potentially detecting liquid water on the surfaces of terrestrial exoplanets. We close out with our chief scientist, Bruce Betts, for What's Up and a new random space fact.

Tabletops and telescopes: NASA’s RPG and the hunt for habitable worlds

Sometimes, misunderstandings can spark beautiful adventures. This week on Planetary Radio, we explore the story behind the naming of Zoozve, a quasi-moon of Venus, with Latif Nasser, co-host of Radiolab. He shares how a typo on a space poster led the Radiolab team on an epic quest to convince the International Astronomical Union to name this quirky space object. Then, Bruce Betts, our chief scientist, pops in for What's Up and a discussion of some of the things asteroid hunters have found lurking in our Solar System.
