Life on the Moons of Jupiter and Saturn through Panspermia?

  A new study suggests the possibility of transfer of life from the inner Solar System to the moons orbiting Jupiter and Saturn, although very rare, cannot be ruled out. A comparison portrait of Jupiter’s four Galilean moons Io, Europa, Ganymede, and Callisto, each with different characteristics. (In this image composite, Jupiter is not at [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]

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]

Ice on Lakes and Seas at Saturn's Moon Titan

  A new paper by scientists on NASA’s Cassini mission finds that blocks of hydrocarbon ice might decorate the surface of existing lakes and seas of liquid hydrocarbon on Saturn’s moon Titan. The presence of ice floes might explain some of the mixed readings Cassini has seen in the reflectivity of the surfaces of lakes [continue reading]
