PASADENA, Calif. (AP) -- Scientists say they have found the best evidence yet that an ocean of liquid water may be hidden below the surface of Saturn's giant moon Titan. If the results are confirmed, it would be a starting point for further study into whether the ocean could be capable of supporting life.

The latest evidence of an underground ocean is indirect and is based on analyzing radar images and Titan's spin rates from observations by the international Cassini spacecraft from 2004 to 2007.

Scientists found several dunes, channels, lakes and other geological features on Titan's surface drifted from a fixed point, likely as a result of an increase of the moon's rotation.

If an internal ocean exists on Titan, it would likely be buried below 62 miles of ice and made of water and traces of ammonia, Lorenz said.
