Europa (in astronomy)

Europa (yŏŏrō´pə), in astronomy, one of the 39 known moons, or natural satellites, of Jupiter. Magnetic-field data collected by the space probe Galileo in 2002 strongly indicates a liquid-water ocean—similar to oceans found on Earth and possibly capable of supporting simple life forms—beneath Europa's frozen surface.

Europa

Europa Smallest of Jupiter's Galilean satellites, with a diameter of 3138km (1950mi). Mainly rock, Europa's smooth water-ice crust is criss-crossed by a network of light and dark linear markings. A form of ice tectonics might be operating on the planet, since there are very few craters.
