More than 400 years after its discovery by Galileo, the largest moon in the solar system has finally claimed a spot on the map. A team of scientists led by Wes Patterson of the Johns Hopkins Applied ...

Last week, researchers released the first-ever geological map of Ganymede, Jupiter’s largest moon. Here’s the map again, flattened into a 2D, rectangular map ...

Technology has radically changed the contributions that amateurs can make to the field of astronomy. Using a readily-available ‘hobby’ telescope, off-the-shelf camera and computer equipment, plus ...

Our solar system’s largest moon, Ganymede of Jupiter, has never been completely mapped — until now. Scientists led by Wheaton College’s Geoffrey Collins combined data from NASA’s Voyager 1, 2 and ...

Image data reanalysis has revealed that ancient tectonic troughs are concentrically distributed across almost the entire surface of Jupiter's moon Ganymede. Computer simulation results suggest that ...

Left to right: The mosaic and geologic maps of Jupiter’s moon Ganymede were assembled incorporating the best available imagery from NASA’s Voyager 1 and 2 spacecraft and NASA’s Galileo spacecraft.

NASA’s Juno spacecraft has imaged Ganymede, Jupiter’s largest moon, and has captured images showing how its unusual magnetic field affects the ice at its poles. Juno passed by Ganymede on December 26, ...

With Europa and Enceladus getting most of the attention for their subsurface oceans and potential to host life, other frozen worlds have been left in the shadows—but the mysterious Jovian moon ...

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 in our entire solar system. Researchers made the discovery ...
