Ganymede is larger than Europa, the largest of all moons we have in the solar system. And it is the only moon that produces its own magnetic field in the interior. Only planets and suns or stars ...

A new study revealed that a massive asteroid may have hit Jupiter’s moon Ganymede about 4 billion years ago, shifting the moon on its axis.

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.

“Because Ganymede is so big, its interior structure is more complicated” than that of smaller worlds, explains University of Arizona geologist Adeene Denton, ...

New simulations show that Jupiter's massive moon Ganymede was knocked off its axis when it was struck by a roughly ...

The solar system's largest moon, Ganymede, which orbits the largest planet, Jupiter, was hit by an asteroid four billion years ago that shifted the gas giant's satellite on its axis, new research ...

Ganymede, which is 50% larger than our own moon, ... but the thermal and structural effects of the impact on the interior of Ganymede have not yet been investigated at all," Hirata said.

This impact that caused Ganymede to shatter hasn't left an obvious crater because it basically splashed the surface, which filled in the hole soon afterward. And that's where things get interesting.

"This impact would affect the interior structure of Ganymede significantly, because the size of the transient crater reaches 25 percent of the size of Ganymede." A giant asteroid colliding with a ...
