Signs of Ocean Beneath Titan's Crust?

March 25, 2008 / Posted by: Daniella Scalice

NASA’s Cassini spacecraft has discovered evidence that points to the existence of an underground ocean of water and ammonia on Saturn’s moon Titan. The Cassini science team detail their findings in this week’s Science, explaining that radar mapping of Titan revealed a shift in landmarks on the moon’s surface of up to 30 kilometers between October 2004 and May 2007. The best explanation, they say, is an underground ocean that disconnects Titan’s icy crust from its rocky interior.
