Cassini finds fresh organic molecules on Saturn's Moon
NASA's Cassini mission has detected fresh, complex organic molecules erupting from the subsurface ocean of Saturn's moon Enceladus. The spacecraft, flying just 13 miles above the surface, sampled ice grains in active plumes and found aliphatic, cyclic, nitrogen- and oxygen-bearing compounds, including double-bonded molecules. The findings support evidence that Enceladus could be habitable.
