The Cassini spacecraft--a joint operation between Nasa (United States), the European Space Agency (Esa), and the Italian Space Agency (Asi)--has found evidence of massive clouds of ethane on Saturn's moon Titan. Scientists think this cloud system rains or snows ethane into lakes of liquid ethane on the surface. Ethane is an odorless, colorless, flammable gas. The findings are published in the journal Science.
