Ganymede News
Ganymede is the largest moon of Jupiter and the largest in the solar system, surpassing even the planet Mercury in diameter. Discovered by Galileo Galilei in 1610, Ganymede is primarily composed of water ice and silicate rock. It is unique among the moons of the solar system for possessing a magnetic field, likely generated by a liquid iron or iron-sulfide core, which suggests a differentiated internal structure. Ganymede’s surface features a mix of two distinct terrains: highly cratered dark regions and somewhat younger, lighter regions marked with extensive grooves and ridges. These characteristics indicate geological activity in its past. Additionally, it is believed that Ganymede has a subsurface ocean, which could contain more water than all of Earth’s oceans combined, making it a place of interest for astrobiological research.
