PASADENA, Calif., Jan. 8 (UPI) -- Blocks of hydrocarbon ice might be floating on the surface of existing lakes and seas of liquid hydrocarbon on Saturn's moon Titan, U.S. researchers say.
The presence of ice floes could explain some of the mixed readings the Cassini spacecraft has seen in the reflectivity of the surfaces of lakes on Titan, NASA's Jet Propulsion Laboratory in Pasadena, Calif., reported Tuesday.
