Few moons in the solar system are as intriguing as Jupiter’s moon Europa. A global ocean of salt water almost certainly surrounds the moon — and it holds more water than any ocean on Earth. Above this immense sea, where surface temperatures dip to minus 300 degrees Fahrenheit, a crust of water ice forms a shell. Astronomers predict that Jupiter, which bombards the moon with intense radiation, causes the entire moon to groan with gravity’s tug. Europa’s liquid water is a tempting target for future missions looking for possible alien microbes.
