I. What is Europa’s ice shell? Europa, one of Jupiter’s moons, is covered by a thick layer of ice that is estimated to be around 10-15 miles thick. This ice shell is thought to cover a subsurface ocean that could potentially harbor life. The ice shell is constantly shifting and cracking due to the gravitational … Read more
