Tides of Titan Reveal Undergroud Ocean
Saturn’s largest moon Titan may have a huge subsurface ocean according to new data from NASA’s Cassini spacecraft.
"Saturn’s gravity is generating tidal forces, tugging and stretching Titan, just as (to a lesser extent) the Moon raises tides on Earth," says Cassini scientist Dr Sami Asmar from NASA’s Jet Propulsion Laboratory in Pasadena, California.
"By monitoring how much Titan is deforming, we can start to draw conclusions about the composition of its interior."
