Jovian Worlds

August 9, 1997 | Volume 152 | Number 6

Cover: Four alien worlds -- the large moons of Jupiter known as (top to bottom) Io, Europa, Ganymede, and Callisto -- are revealing their distinctive personalities. Data recorded by the Galileo spacecraft are providing new evidence that the tug-of-war between these moons and Jupiter has profoundly affected the moons' evolution. This composite image includes a snapshot of Callisto taken by Voyager in 1979 and photos of the other moons from Galileo's current mission (Image: NASA/JPL)
