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.

Ganymede, which is 50% larger than our own moon, has an ocean beneath its icy surface – up to 60 miles deep – and is suspected of being able to support primitive life.

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 ...

By Ashley Strickland, CNN (CNN) — 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 is the only moon in the solar system with a magnetic field. “This suggests we are seeing the remnants of a deep ocean brine that reached the surface of this frozen world,” said Bolton.

Ganymede is a tidally locked moon, which means it always shows the same face to Jupiter—and, as a result of the impact, the crater is permanently shielded from Jupiter’s view.

For context, Ganymede is not only the largest moon in the solar system at a radius of 1,637 miles (2,634 kilometers), but it is also larger than the planet Mercury. “I want to understand the origin ...

Two recent studies published in Icarus examine tectonic processes known as shear stresses which are also referred to as strike-slip faults on Saturn’s largest moon, Titan, and Saturn’s largest moon, ...

Discovered by Galileo in 1610 while he was messing about with his new telescope, Ganymede is not only the largest moon of the planet Jupiter, but the largest in the solar system.

By Ashley Strickland, CNN (CNN) — 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, is even bigger than Mercury and the dwarf planet Pluto. And past research has found evidence suggesting that beneath its thick, icy crust lies a ...
