The surface of Europa is predominantly water-ice, the darker brown color is due to rocky material. The dark lines, some thousands of km long, are fractures in the crust. The bright feature towards the lower right of the disk is the 45 km diameter crater Pwyll, centered at 25.2 S, 271.4 W. Europa is 3122 km in diameter and north is up. (Galileo, P-48040)
