Plumes on Icy Worlds Hold Clues About What Lies Beneath

Dec. 16, 2020

A new model shows how brine on Jupiter’s moon Europa can migrate within the icy shell to form pockets of salty water that erupt to the surface when freezing. The findings are important for the upcoming Europa Clipper mission and may explain cryovolcanic eruptions across icy bodies in the solar system.
