Latest Ganymede Stories
The Jupiter Icy Moon Explorer (JUICE) proposal to study the moons of Jupiter is leading the pack of proposed missions.
A team of scientists led by Arizona State University has produced the first complete geologic map of Jupiter’s moon, Io, revealing geologically unique features, volcanoes, and lava flows as well as some relative ages of the moon.
Researchers report this week in the journal Geophysical Research Letters that NASA's Cassini spacecraft has detected oxygen on one of Saturn's moons.
With input from scientists around the world, American and European scientists working on the potential next new mission to the Jupiter system have articulated their joint vision for the Europa Jupiter System Mission.
The frigid ice of Jupiter's moon Europa may be hiding more than a presumed ocean: it is likely the scene of some unexpectedly fast chemistry between water and sulfur dioxide at extremely cold temperatures.
Jupiter's moon Io could be a potential target to look for extraterrestrial life.
Differences in the number and speed of cometary impacts onto Jupiter's large moons Ganymede and Callisto some 3.8 billion years ago can explain their vastly different surfaces and interior states
Planetary scientist Francis Nimmo will outline the impact of ice dynamics on the habitability of the moons of Saturn and Jupiter on Tuesday, December 15, at the annual meeting of the American Geophysical Union in San Francisco.
NASA's Galileo spacecraft began what would become a 14-year odyssey of exploration 20 years ago this Sunday, Oct 18.
Studies of features in Jupiterâ€™s spectacular and rapidly changing aurorae have given new insights into the complex electromagnetic interactions between the giant planet and two of its innermost moons.
Aquila (the Eagle) Constellation -- Location: Northern Hemisphere; Coordinates: Right Ascension: 20h; Declination: 05; Source: Various cultures - Greek, Arab, Persian, Indian, Japanese, Chinese, Korean The story behind the name In the ancient Middle Eastern and Mediterranean cultures, the constellation Aquila is seen as the shape of a flying bird. The pattern contains three prominent stars that can be seen to outline the wings of a bird, but are also the focus of quite different myths...
Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
Jupiter's Moon Callisto -- With a diameter of over 4,800 km (2,985 miles), Callisto is the third largest satellite in the solar system and is almost the size of Mercury. Callisto is the outermost of the Galilean satellites, and orbits beyonds Jupiter's main radiation belts. It has the lowest density of the Galilean satellites (1.86 grams/cubic centimeter). Its interior is probably similar to Ganymede except the inner rocky core is smaller, and this core is surrounded by a large icy...
Jupiter's Moon Ganymede -- Ganymede is the largest satellite in the solar system with a diameter of 5,268 km (3270 miles). It is larger than Mercury and Pluto, and three-quarters the size of Mars. If Ganymede orbited the Sun instead of orbiting Jupiter, it would easily be classified as a planet. If Ganymede orbited the Sun instead of Jupiter it could be classified as a planet. Like Callisto, Ganymede is most likely composed of a rocky core with a water/ice mantle and a crust of rock and...
Jupiter's Moon Europa -- Europa is a puzzle. The sixth largest moon in our Solar System, Europa confounds and intrigues scientists. Few bodies in the Solar System have attracted as much scientific attention as this moon of Jupiter because of its possible subsurface ocean of water. The more we learn about this icy moon, the more questions we have. Because the nature of science is to ask questions, we cannot resist the mystery of Europa and its potential for possessing an ocean. Early...
