Really Cool.
Because Titan, Saturn’s largest moon, is spinning faster than expected, there is likely a liquid ocean 50 or 60 miles below the surface, a team of scientists reported in Friday’s issue of the journal Science. Based on radar images taken on repeated passes by NASA’s Cassini spacecraft, the scientists tracked motion on the surface and found the surface to be rotating slightly faster than expected. They believe seasonal winds in Titan’s atmosphere are pushing on the outer shell, causing it to spin faster. For the outer shell to spin independently, there must be a liquid ocean, probably made of water and ammonia, separating the shell from the inner part of Titan, the scientists reported.
