Galileo's Europa Remastered

Europa, one of Jupiter's large moons, likely hides a deep, global ocean beneath its icy surface. The Galileo spacecraft, looping through the Jovian system in the late 1990s, recorded these views. Improved calibrations reveal the moon's long, curving fractures, hinting at subsurface liquid water. This remastered image approximates what the human eye might see.
