Saturn’s moon Mimas is already an oddity, being the most cratered object in the Solar System and likened to the Death Star of Star Wars fame. But new research this week points to Mimas being even weirder than previously thought.
Cassini, the NASA spacecraft, has found propylene, a chemical commonly used to make plastic kitchen containers on Titan. Titan is Saturn's moon and the chemical was detected in the lower atmosphere. This is the first finding of propylene outside Earth.
NASA scientists report that the Cassini mission has sighted a remarkable likeness to Egypt’s river Nile on Saturn’s large moon Titan. The river valley runs more than 200 miles (about 320 kilometres) from its source to what appears to be a large sea.
A new model developed by scientists working with radar data obtained by NASA's Cassini spacecraft shows that differing densities in the outermost layers of Saturn's moon Titan could explain unusual surface behaviour leading to formation of mountains.

NASA's Cassini spacecraft took this raw, unprocessed portrait of Saturn's moon Rhea on March 10, 2012 from approximately 26,000 miles (almost 42,000 kilometers) away.
