    New Views of Titan's Land of Lakes and Seas

    Newly assembled radar images from the Cassini spacecraft provide the best view of the hydrocarbon lakes and seas on the north pole of Saturn's moon Titan, while a new radar image reveals that Titan's south polar region also has lakes.

    Hot Sources of Jets on Enceladus

    A recent analysis of images from NASA's Cassini spacecraft provides conclusive evidence that the jets of fine, icy particles spraying from Saturn's moon Enceladus originate from the hottest spots on the moon's "tiger stripe" fractures that straddle the moon's south polar region.

    Cassini on the Trail of a Runaway Mystery

    NASA scientists are on the trail of Iapetus' mysterious dark side, which seems to be home to a bizarre "runaway" process that is transporting vaporized water ice from the dark areas to the white areas of the Saturnian moon.

    Turbulence Ahead - Lessons From Titan

    Ever spilled your drink on an airline due to turbulence? Researchers are finding new ways to understand the phenomenon - both in Earth's atmosphere and in that of Saturn's moon, Titan, aided by Huygens probe data.

    Cassini 'Cat Scan' Maps Clumps In Saturn's Rings

    Saturn's largest and most densely packed ring is composed of tightly packed clumps of particles separated by nearly empty gaps, according to new findings from NASA's Cassini spacecraft.

    Frictional Heating Explains Plumes on Enceladus

    Rubbing your hands together on a cold day generates a bit of heat, and the same process of frictional heating may be what powers the geysers jetting out from the surface of Saturn's moon Enceladus.
