This object had a hydrogen atmosphere blown away by solar wind and was thought to develop ridges on its terrain when its neighboring satellite pulled it into an elliptical orbit, squeezing this moon and rumpling its crust. The Hubble Telescope detected an ozone here in 1995, and the Galileo spacecraft has detected a (*) magnetic field around this moon, which is stronger than those found on other satellites. One prominent feature of this moon is the dark plain named Galileo Regio. It is the largest of a group consisting of Callisto, Io, and others that orbit the same planet. For 10 points, identify this moon of Jupiter, the largest satellite in the solar system.
