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, which are important for the upcoming Europa Clipper mission, may explain cryovolcanic eruptions across icy bodies in the solar system. On Jupiter’s icy moon… Continue Reading Researchers Model Source of Eruption on Jupiter’s Moon Europa
