Peering Below Callisto’s Icy Crust with ALMA


What exists beneath the surface of Jupiter’s icy moon, Callisto? This is what a recent study accepted by The Planetary Science Journal hopes to address as a team of researchers investigated the subsurface composition of Callisto, which is Jupiter’s outermost Galilean satellite. This study has the potential to help scientists better understand the interior composition of Callisto, which is hypothesized to possess a subsurface liquid water ocean, and develop new techniques for exploring planetary subsurface environments.
