Arlin P.S. Crotts Radical Hypothesis lecture - The Galilean Moons of Jupiter were thanks to Saturn

The four Galilean moons of Jupiter are thought to have formed within a disk around Jupiter during the last stages of the giant planet’s formation. However, the opening of a gap in the main protoplanetary disk makes delivery of the raw material for these moons very difficult. Thomas Ronnet and colleagues (including myself) have examined the role of Saturn in transporting material across the gap and forming the Galilean moons. If we are right, Galileo Galilei’s discovery of a miniature solar system that kick-started the Copernican revolution depended on Saturn. But more than that, it has implications for the main belt of asteroids, for exomoons, and for potentially solving a puzzle regarding the amount of heavy elements in Jupiter’s envelope
