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

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 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.

Space crash: New research suggests huge asteroid shifted Jupiter's moon Ganymede on its axis An asteroid 20 times larger than the one that struck Earth and led to the extinction of the dinosaurs ...

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.

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. In fact, it's ...

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.

Ganymede is a particularly weird place. Not only is it Jupiter’s most massive satellite, it’s the biggest moon in the whole solar system.

🔭 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.

Jupiter's jumbo-size moon Ganymede and icy moon Europa posed for the most detailed images ever taken of them from Earth. Planetary scientists from the University of Leicester used the European ...

Essentially, water vapor is escaping from Ganymede’s surface, resulting in the molecules detected in the moon’s atmosphere. HERE’S THE BACKGROUND — Jupiter has a total of 79 known moons.
