Large Ocean Inside Saturn's Moon Enceladus

  NASA’s Cassini spacecraft and Deep Space Network have uncovered evidence Saturn’s moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the moon as a potential home to extraterrestrial microbes. Gravity measurements by NASA’s Cassini spacecraft and Deep Space Network suggest that Saturn’s moon Enceladus, which has jets of water vapor [continue reading]

Household Plastic in Titan's Atmosphere

  NASA’s Cassini spacecraft has detected propylene, a chemical used to make food-storage containers, car bumpers and other consumer products, on Saturn’s moon Titan. This is the first definitive detection of the plastic ingredient on any moon or planet, other than Earth. NASA’s Cassini spacecraft looks toward the night side of Saturn’s largest moon and sees [continue reading]

Titan has a Thick, Rigid and Weathered Ice Shell

  An analysis of gravity and topography data from Saturn’s largest moon, Titan, has revealed unexpected features of the moon’s outer ice shell. The best explanation for the findings, the authors said, is that Titan’s ice shell is rigid and that relatively small topographic features on the surface are associated with large roots extending into [continue reading]

Saturn's Moon Dione Might Have a Subsurface Ocean

  From a distance, most of Saturn’s moon Dione resembles a bland cueball. Thanks to close-up images of a 500-mile-long (800-kilometer-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. The Cassini spacecraft looks [continue reading]

Anne's Picture of the Day: Saturn’s moon Titan

April 16, 2013 Titan, Saturn’s largest moon Image Credit: NOAA/NASA/ESA Titan is, with a diameter of 5,150 kilometers (3,200 miles), Saturn’s largest moon and the second largest moon in our Solar System (only Jupiter’s moon Ganymede is larger), roughly 50% larger than our own Moon and 80% more massive. Titan orbits Saturn at a distance [continue reading]
