As Saturn’s largest moon, Titan earns its name. It’s also the only known body other than Earth with seas, numerous surface lakes, and even rainy weather. Now scientists have mapped out Titan’s polar lakes for the first time, revealing information about the moon’s climate and surface evolution. They found that the lakes formed differently than had been previously thought—and differently than any lakes on Earth. A collaboration of scientists led by Alexander Hayes of Cornell [...]

NASA’s Cassini spacecraft has measured a curious abundance of methane spewing into the atmosphere of Saturn’s icy moon Enceladus. A team of American and French scientists published findings in Geophysical Research Letters suggesting two scenarios that could explain the methane abundance observed in the

“NASA’s Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn’s north pole. This is the first hexagon movie of its kind, using color filters, and the first to show a complete view of the top of Saturn down to about 70 degrees latitude.” Quoted

A larger version is here. From NASA JPL today: PASADENA, Calif. — Color and black-and-white images of Earth taken by two NASA interplanetary spacecraft on July 19 show our planet and its moon as bright beacons from millions of miles away in space. NASA’s Cassini spacecraft captured the color images of Earth and the moon from its perch in the Saturn system nearly 900 million miles (1.5 billion kilometers) away.

“From a distance, most of the Saturnian moon Dione resembles a bland cueball. Thanks to close-up images of a 500-mile-long mountain on the moon from NASA’s Cassini spacecraft, scientists have found more evidence for the idea that Dione was likely active in the past. It could still be active now.” Quoted from the NASA press
