Birth conditions fixed water contrast on Jupiters moons
While Io, the most volcanically active moon in the solar system, appears completely dry and devoid of water ice, its neighbor Europa is thought to harbor a vast global ocean of liquid water beneath an icy crust. A new international study co-led by Aix-Marseille University and Southwest Research Institute finds that this stark contrast in water content was imprinted at birth as the moons formed a
