We celebrate 18 years of Planetary Radio with two great features and 10 personal questions for host Mat Kaplan from Planetary Society Chief Scientist Bruce Betts. Astronomer Jane Greaves is back with an update on the phosphine gas detected above Venus. Then we find water right out under the Sun on our own Moon. Research leader Casey Honnibal tells us how her team found it using the SOFIA telescope on a 747.

More Moon Water and an Update from Venus on Our 18th Anniversary!

Two hot Jupiters presented at the 248th American Astronomical Society meeting push our understanding of exoplanet atmospheres to the extreme. Research Scientist Tiffany Kataria from NASA's Jet Propulsion Laboratory shares new JWST observations of HD80606 b, the "Roasted Planet,”a gas giant on one of the most eccentric orbits ever discovered. Assistant Professor Lisa Dang of the University of Waterloo joins to discuss CoRoT-2 b, a young, inflated hot Jupiter whose hottest point shows up in an unexpected location on the exoplanet, possibly because the planet hasn't fully tidally locked with its star yet. Then Chief Scientist Bruce Betts joins for What's Up to explore atmospheric super-rotation, winds that outrun the worlds they ride on.

Hot Jupiters: The ‘Roasted Planet’ and the wrong-way hotspot

It may be the best book subtitle we’ve encountered in the Planetary Society book club: “Particles, Poetry and the Cosmic Dream Boogie.” Theoretical physicist and black feminist science theorist Chanda Prescod-Weinstein has followed her acclaimed first book, “The Disordered Cosmos,” with this new, equally celebrated, deeply personal romp across the Universe, “The Edge of Space-Time”.  Swinging from quantum mechanics to hip-hop, and from galaxies to Alice in Wonderland, she guides us through the looking glass to what we know and would love to know about the Universe. It all but guaranteed a mind-bending conversation with host Mat Kaplan that begins with Chanda’s concern for the state of scientific research in the United States, and ends among the stars.

Book Club Edition: “The Edge of Space-Time” by Chanda Prescod-Weinstein

“Baby's Guide to the Night Sky” introduces the youngest kids — down to newborns — to constellations and the wonders of the Cosmos. It comes from two people who've spent their lives chasing that same wonder in very different ways.

This week, we are joined by authors Sian Proctor and John Read. Sian Proctor is a geoscientist, artist, poet, and commercial space astronaut who served as pilot of Inspiration4 in 2021, becoming the first Black woman to serve as a mission pilot in space. John Read is an astronomer and science communicator who left a career in corporate finance after a single look through a telescope changed his life. He now hosts the YouTube channel LearnToStargaze and has authored several astronomy books, including “A Kid's Guide to the Night Sky.” We'll talk about how the two of them met, how they turned a lifetime of expertise into something a baby can enjoy, and why it's never too early to start looking up. 

Stick around after the interview for What’s Up with Bruce Betts, our chief scientist, to review the book and walk through some of the night sky objects it features.
