Jupiter’s Galilean Moons May Have Formed Slowly

Mara Johnson-Groh, Science Writer by Mara Johnson-Groh 30 September 201922 July 2024

A new model is the first to simultaneously explain many of the moons’ characteristics, including their mass, orbits, and icy composition

Mmm, Salt—Europa’s Hidden Ocean May Contain the Table Variety

Katherine Kornei, Science Writer by Katherine Kornei 9 July 20197 March 2022

Hubble Space Telescope observations suggest that sodium chloride exists in young, geologically active regions on Europa, likely fed by upwelling from the moon’s subsurface ocean.

Huge Blades of Ice May Partially Cover Jupiter’s Moon Europa

Katherine Kornei, Science Writer by Katherine Kornei 23 October 201829 September 2021

Conditions are right for “penitentes” up to 15 meters high to form on the Jovian moon, new research shows. The spires might prevent a lander from exploring Europa’s equatorial region.

How Hot Is Europa? Now There’s a Map for That

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 5 September 201822 March 2023

The new global map of Europa’s surface heat also highlighted one spot on the moon that is inexplicably cold.

New research suggests that the movement of Europa’s ice crusts could be a sign of life.

Seeking Salt That Surfaces from Europa’s Hidden Ocean

Sarah Stanley, Science Writer by Sarah Stanley 31 January 20187 March 2022

Irradiation-induced color changes in sodium chloride could reveal whether it came from ocean water mixing with surface water, a key component of the moon’s potential to support life.
