Researchers believe that Ganymede’s interior may be like a club sandwich, stacked with alternating layers of ice and ocean.

Ganymede is having a moment because NASA’s Juno mission observed salts and organic compounds on its surface, possibly from an ocean that lies beneath its crust of ice.

However, other current research suggests that Ganymede doesn’t have a liquid water layer directly touching its mantle. Instead, icy crusts separate the ocean from the rock.

A recent study published in Nature Astronomy examines how NASA’s Juno spacecraft identified the presence of mineral salts and organic compounds on Jupiter’s third Galilean moon, Ganymede, which ...

During a June 2021 flyby of Ganymede, NASA’s Juno spacecraft used its own infrared eyes, a spectrometer named the Jovian Infrared Auroral Mapper (JIRAM), to measure the components of the moon ...

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.

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, which is the largest moon in the Solar System, is also one of its ‘ocean worlds’. Most of these are moons that have an icy crust on top of a subsurface ocean.
