While Ganymede hasn’t yet been observed spewing plumes of water vapor like Saturn’s moon Enceladus, Jupiter’s largest moon is most likely hiding an enormous saltwater ocean.

Jupiter’s moon Ganymede may have shifted on its axis when a massive asteroid smashed into it about 4 billion years ago, according to a new study. Ganymede, the largest moon in the solar system ...

Jupiter presents the brightest auroras in the solar system. One of the unique features of this planet, which it shares with Saturn, is also the presence of auroral emissions caused by three of its ...

A colossal asteroid slammed into Jupiter's largest moon Ganymede with so much power it dramatically and permanently reoriented the moon roughly 4 billion years ago, new research suggests.

Ganymede, one of those moons and the largest moon in the solar system — at 3,270 miles (5,268 kilometers) wide, it's bigger than the planet Mercury — has a vast ocean underneath its icy crust.

Credits: NASA/JPL-Caltech/SwRI) Ganymede is one of Jupiter’s 79 confirmed moons and it’s the only moon with its own magnetic field. It’s also thought to have an underground saltwater supply.

New data from NASA’s Juno spacecraft suggests that there are mineral salts and organic compounds on the surface of Jupiter’s giant moon Ganymede.

Nearby Jupiter has such a strong magnetic field that organic compounds and salts on the surface of Jovian moons would have a hard time surviving. However, the region around Ganymede's equator ...
