Perfect examples of icy moons are 3 of the Galilean satellites, Europa, Ganymede, and Callisto. Except maybe for Europa and Triton, these moons have no atmosphere and no magnetosphere. Surfaces of some of these moons, particularly that of Ganymede, reveal, however, that their evolution included activity in the interior which ultimately resulted in a change in the moon's appearance. Activity in the interior could also provide an environment suitable for life. |

But the surfaces of these moons, especially Ganymede, show that in their history, something may have happened inside which changed the way the surface of the moon looks today.
