They are not for everyone, but there’s no doubt that alcoholic beverages have been part of human culture for as long as there has been human culture. And there’s no reason to think booze won’t follow us across the solar system. Host Mat Kaplan talks with Chris Carberry about his comprehensive and eye-opening book, Alcohol in Space: Past, Present and Future. The December Solstice edition of The Planetary Report has just been published online. Editor-in-chief Emily Lakdawalla provides an enticing overview of its contents. We’ve also got headlines from The Downlink, and a glance at the crowded night sky in What’s Up.

A Toast to Alcohol in Space

Could a single ancient impact have briefly transformed one of the Solar System’s darkest moons into a cryovolcanic world?

When Voyager 2 flew past Uranus in 1986, it captured the only close-up images we have of Umbriel, a heavily cratered, charcoal-dark satellite long considered geologically inactive. But one feature stands out: a bright ring inside the 131-kilometer-wide Wunda crater.

In this episode, Sarah Al-Ahmed speaks with Adeene Denton, NASA postdoctoral program fellow at the Southwest Research Institute, about her team’s new study published in the Journal of Geophysical Research: Planets. Using shock physics simulations, Denton and her colleagues reconstruct the impact that formed Wunda crater to determine what Umbriel’s interior must have been like at the time. Their modeling explores whether impact-induced cryovolcanism can explain the bright deposits observed on the crater floor.

Then, in What’s Up, Bruce Betts, chief scientist of The Planetary Society, joins Sarah to break down one of the key mechanisms that keeps icy moons from freezing solid, tidal heating driven by orbital resonance.

A new study explores whether a massive ancient impact briefly triggered cryovolcanism on Uranus’s moon Umbriel. Sarah Al-Ahmed speaks with Adeene Denton about how crater modeling reveals clues to the moon’s hidden interior.

Did an impact trigger cryovolcanism on Umbriel?

They informed and entertained together throughout the first 20 years of Planetary Radio. Listen in as the Society’s chief scientist and book club edition host Mat Kaplan share the mic once again for a delightful conversation about Dr. Betts’ two new space books for young people. “Are We Alone?” introduces the search for life across the Universe, while “The Size of Space” collects many of Bruce’s brilliant and hilarious ways to cut our Solar System down to human size.

Book Club Edition: Planetary Society Chief Scientist Bruce Betts’ latest for kids

This week on Planetary Radio, we mark a major leadership transition at The Planetary Society. Host Sarah Al-Ahmed sits down with Bill Nye, outgoing chief executive officer and newly appointed chief ambassador of The Planetary Society, and Jennifer Vaughn, incoming chief executive officer and former chief operating officer, for a candid conversation about this long-planned transition. Together, Bill and Jenn reflect on how the organization, under their shared leadership, grew into the world’s largest and most effective nonprofit dedicated to advancing the scientific exploration of space.

Then, Bruce Betts, chief scientist of The Planetary Society, joins Sarah for What’s Up. They discuss an upcoming planetary alignment on and around February 28, 2026.
