Craters appear well defined on icy Rhea in front of the hazy orb of the much larger moon Titan in this Cassini spacecraft view of these two Saturn moons. Lit terrain seen here is on the leading hemispheres of Rhea Continue reading
The international Cassini mission has spotted what appears to be a miniature extraterrestrial version of the Nile River: a river valley on Saturn’s moon Titan that stretches more than 400 km from its ‘headwaters’ to a large sea. It is Continue reading
Data from NASA’s Cassini spacecraft tie a shift in seasonal sunlight to a wholesale reversal, at unexpected altitudes, in the circulation of the atmosphere of Saturn’s moon Titan. At the south pole, the data show definitive evidence for sinking air Continue reading
A giant of a moon appears before a giant of a planet undergoing seasonal changes in this natural color view of Titan and Saturn from NASA’s Cassini spacecraft. Titan, Saturn’s largest moon, measures 3,200 miles, or 5,150 kilometers, across and Continue reading
Saturn’s moon Titan turns out to be flatter than it should be. Two Cassini scientists have a new and unusual theory about what causes Titan to have the shape it has: weather. The moon hits your eye like a big Continue reading
A literal shot in the dark by imaging cameras on NASA’s Cassini spacecraft has yielded an image of a visible glow from Titan, emanating not just from the top of Titan’s atmosphere, but also – surprisingly – from deep in Continue reading
