Far across the solar system, from where Earth appears merely as a pale blue dot, NASA's Galileo spacecraft spent eight years orbiting Jupiter.

Russian plans to send a lander to Ganymede, the Laplace mission, and an orbiter to Mercury. This video from the Russian space agency ROSCOMOS provides an update on the missions.

NASA's Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon.

The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon's makeup.

First Global Geologic Map of Ganymede

More than 400 years after its discovery by Galileo, the largest moon in the solar system has finally claimed a spot on the map.

On Dec. 6, 1998, the crew of space shuttle mission STS-88 began construction of the International Space Station, attaching the U.S.-built Unity node and the Russian-built Zarya module together in orbit.

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 experienced observing skills, Emmanuel I. Kardasis of the Hellenic Amateur Astronomy Association has produced the first amateur albedo map of Jupiter's moon Ganymede.

"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 experienced observing skills, Emmanuel I. Kardasis of the Hellenic Amateur Astronomy Association has produced the first amateur albedo map of Jupiter's moon Ganymede. This demonstration has implications for the future role of amateur astronomers. The work will be presented at the European Planetary Science Congress in Madrid. An albedo map details higher areas of reflectivity on an object's surface recording where material is brighter or darker. Kardasis' albedo map closely aligns with professional images of Ganymede's surface, indicating features such as Phrygia Sulcus (furrows and ridges 3700km across) and the Nicholson region (a low-lying darker area)."
