Volcanoes aren’t just an earthly phenomenon. They’re found all across the Solar System. In this compilation episode of Planetary Radio, we explore volcanic and geothermal activity on planets, moons, and distant dwarf planets. You’ll hear from Rosaly Lopes, Nick Schneider, Rae Paoletta, Robbie Herrick, Scott Hensley, and Christopher Glein as they share insights into everything from lava flows on Venus and eruptions on Io to the mysterious heat signatures of icy bodies like Eris and Makemake. This journey spans over 20 years of Planetary Radio, featuring interviews hosted by both current host Sarah Al-Ahmed and founding host Mat Kaplan.
Then, our Chief Scientist, Dr. Bruce Betts, returns for What’s Up and shares new findings from NASA’s Juno mission, which recently completed close passes by Jupiter’s volcanic moon, Io.
