Callisto’s H Corona: Offspring of the Surface or the Atmosphere?

by Beatriz Sánchez-Cano and Anni Määttänen 7 December 202222 July 2024

The mostly unknown Callisto’s H corona is created by a global tenuous H2 atmosphere and not by surface water as previously believed, providing the first evidence for H2 in Callisto’s atmosphere.

Europa’s Plate Tectonic Activity Is Unlike Earth’s

by Morgan Rehnberg 29 November 202227 January 2023

The moon of Jupiter has likely experienced intermittent, regional plate tectonic activity in the past, although the plates are currently dormant.
