LIFE ON OTHER PLANET
the next-best shot at finding extra-terrestrial life forms is on Europa, a moon of the planet Jupiter. Right now, there is no other body in the solar system that attracts as much scientific attention as this bright strange-looking moon, the smallest of Jupiter's four large satellites. Europa is the fourth largest moon of Jupiter and the sixth largest moon in the solar system. Europa's surface is covered with ice. Europa has an icy crust that has been severely fractured, as indicated by the dark linear, curved, and wedged-shaped bands seen in images of the surface. These fractures have broken the crust into plates as large as 30 kilometers (18.5 miles) across. we can tell that it has a shell of water ice, parts of which could be liquid. Models of Europa's interior show that beneath a thin 5 km (3 miles) crust of water ice, Europa may have oceans as deep as 50 km (30 miles) or more.
