NASA's Voyager 2 spacecraft snapped this color image of Jupiter's moon Ganymede, the largest satellite in the solar system, on July 7, 1979 from a distance of 745,000 miles (1.2 million kilometers).

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.

Photos: NASA Jupiter probe images huge moon Ganymede like never before But if an impact was to blame, quite a large asteroid — at least 30 miles (50 kilometers) across and possibly more like 90 ...

Ganymede and Jupiter are in a complicated relationship, and some of that relationship extends to Ganymede's surface chemistry, where Jupiter's plasma strikes the moon's poles and irradiates the ice.

Astronomers find 12 new moons orbiting Jupiter 00:33. NASA has detected water vapor for the very first time in the atmosphere of Ganymede — not only Jupiter's largest moon, but the largest moon ...

It’s Ganymede, Jupiter’s monster-sized moon, which NASA’s Juno spacecraft has been seeing a lot of lately. During its most recent close flyby ...

Ganymede, Jupiter's biggest moon, is throwing shade at gas giant Jupiter -- and you can watch live. Jackson Ryan Former Science Editor. Jackson Ryan was CNET's science editor, and a multiple award ...

🔭 Ganymede, Jupiter's moon, has its own radiation belts. ... After a few orbits of Ganymede, particles from Jupiter's magnetosphere can either return to it or impact the moon's surface.

The European Space Agency’s $1.7 billion Jupiter Icy Moons Explorer (JUICE) spacecraft blasted-off in April ultimately to go into orbit around Ganymede for nine months from late 2034.

Jupiter may have two moons capable of supporting life as we know it. Like its famous neighbor Europa, the huge Jovian satellite Ganymede might have an ocean of liquid water in contact with a rocky ...
