Latest Callisto Stories
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 is approaching Earth for the closest encounter between the two planets in more than a decade--and it is dazzling.

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
NASA's Galileo spacecraft began what would become a 14-year odyssey of exploration 20 years ago this Sunday, Oct 18.
Scientists have assembled the first global geological map of the Solar Systemâ€™s largest moon â€“ and in doing so have gathered new evidence into the formation of the large, icy satellite.
A new study plans to determine just how hazardous an impact the radiation belts have on the Jovian system.
Ursa Minor (little dipper) Constellation -- Ursa Minor is a constellation in the northern sky, whose name means the "Lesser Bear" in Latin. It is one of the 88 modern constellations, and was also one of the 48 listed by Ptolemy. It is notable as the location of the north celestial pole, although this will change after some centuries due to the effects of precession. Notable features Ursa Minor contains an asterism colloquially known as the "Little Dipper" because its brightest...
Ursa Major (big bear) Constellation -- Location: Northern Hemisphere; Coordinates: Right Ascension: 11h; Declination: +50; Source: Greek, Roman, and Native American mythology The constellation name, Ursa Major, means Big Bear. The "bear" association has its origins in two major civilizations which saw two very different bears in the sky. The Greeks who named this constellation (later translated into the Latin name we use today) thought that the stars outlined the shape of a bear walking...
Big Dipper Constellation (Ursa Major) -- Ursa Major is a constellation visible throughout the year in the northern hemisphere. Its name means "Great Bear" in Latin, and is derived from the legend of Callisto. Its seven brightest stars form a famous asterism known in the United States as the Big Dipper, because the major stars can be seen to follow the rough outline of a large ladle, or dipper. The Big Dipper is recognized as a grouping of stars in many cultures and eras. In the United...
Saturn's moon Rhea -- Rhea is the second largest moon of Saturn. It was discovered in 1672 by Giovanni Cassini. Rhea is an icy body with a density of about 1.24 gm/cm3. This low density indicates that it has a rocky core taking up less than one-third of the moon's mass with the rest composed of water-ice. Rhea's features resemble those of Dione, with dissimilar leading and trailing hemispheres, suggesting similar composition and histories. The temperature on Rhea is -174°C in direct...
Saturn's moon Tethys -- Tethys is a moon of Saturn that was discovered by Giovanni Cassini in 1684. Tethys is an icy body similar in nature to Dione and Rhea. The density of Tethys is 1.21 g/cm3, indicating that it is composed almost entirely of water-ice. Tethys's surface is heavily cratered and contains numerous cracks caused by faults in the ice. There are two different types of terrain found on Tethys, one composed of densely cratered regions and the other consisting of a dark...
