Latest Ganymede Stories
Jupiter's moon Ganymede, the largest satellite in our solar system, has two types of terrain on the surface: highly cratered dark regions comprising nearly 40 percent of the surface, with the rest being lightly grooved in intricate patterns.
While astronomers have long believed that Jupiter’s moon Ganymede was home to a thick ocean sandwiched between two layers of ice, researchers now claim that the largest natural satellite in our solar system could actually have several layers of ice and ocean stacked one upon another.
A team of scientists from Wheaton College have produced the first geological map of Jupiter's largest moon, Ganymede. The map, which has been published by the USGS, was created using images taken by NASA's Voyager and Galileo spacecraft.
Forty years ago, man’s perspective of what blanketed the night sky grew even more dense as NASA's Pioneer 10 made its closest approach to Jupiter.
Researchers from Chalmers University of Technology in Sweden have announced the development of a groundbreaking sensor that could eventually be used to scan the atmospheres of Jupiter’s moons and other planetary bodies.
Concentrations of volcanic activity in Jupiter's moon Io are significantly displaced from where they are expected to be based on models used to predict how the moon's interior is heated.
The JUpiter ICy moons Explorer mission, JUICE, will carry a total of 11 scientific experiments to study the gas giant planet and its large ocean-bearing moons, ESA announced today.
New research based on observations from NASA's Cassini spacecraft show that Titan, Saturn's largest moon, may look younger than it really is.
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...
