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]

Oxygen detected in atmosphere of Saturn’s Moon Dione

Discovery could mean ingredients for life are abundant on icy space bodies Los Alamos National Laboratory scientists and an international research team have announced discovery of molecular oxygen ions (O2+) in the upper-most atmosphere of Dione, one of the 62 known moons orbiting the ringed planet. The research appeared recently in Geophysical Research Letters and [continue reading]
