Europa: Facts - NASA Science
WEBBased on Europa's icy composition, scientists think the most likely material to create this magnetic signature is a global ocean of salty water. Scientists think Europa’s ice shell is 10 to 15 miles (15 to 25 kilometers) thick, floating on an ocean 40 to 100 miles (60 to 150 kilometers) deep.
