On Monday (June 7), NASA's Juno probe zoomed within just 645 miles (1,038 kilometers) of Jupiter's enormous satellite Ganymede, which is bigger than the planet Mercury. It was the closest any ...

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's interior, seen here, is composed of an iron core, rocky mantle, icy mantle, 100 kilometer deep liquid ocean and icy crust. Image released March 12, 2015.

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 ...

“— right.” “It’s that we keep seeing Ganymede as an object we’re studying and not as a place we live —” “Please stop explaining the food to me and let me eat it.” “Sorry.
