Europa is a rocky object covered with an extremely smooth, elaborately patterned surface of ice ...
Europa’s ocean is considered one of the most promising places in the solar system to look for life beyond Earth.

Europa is the fourth largest of Jupiter’s 95 moons. It's the sixth-closest moon to the planet. Europa may be one of the most promising places in our solar system to find present-day environments suitable for some form of life beyond Earth. Scientists believe a saltwater ocean lies beneath its icy shell, holding twice as much water as Earth's global ocean. It also may have the chemical ...
