Summary

With the public still dazzled by the possibility of life on Mars, space scientists announced new views of another set of alien worlds: Jupiter and its moons. As it swung through the Jovian system, the Galileo spacecraft took new images of Jupiter and another moon, Europa. The data suggest that a watery ocean—one of the criteria for life as we know it—may lie beneath the cracked, icy shell of Europa's surface. And on Jupiter itself, Galileo snapped images of Earth-like thunderclouds, shoring up the idea that thunderstorms sweep across the planet.
