Jupiter's Moons and Their Features

The video explores the discovery and characteristics of Jupiter's four largest moons: Io, Europa, Ganymede, and Callisto. Galileo Galilei first observed these moons, known as the Galilean moons, in 1610. Io is the most geologically active body in the solar system, with over 400 volcanoes. Europa, with its icy surface, may harbor an ocean beneath, potentially supporting life. Ganymede, the largest moon, has a magnetosphere, while Callisto is heavily cratered. Upcoming missions aim to study these moons further.
