Enceladus day for Cassini

The Cassini spacecraft continues its tour of the Saturn system with a close encounter with the SII/Enceladus today. NASA has released some new images of Titan which add more evidence in support of fluid activity on Titan's surface. (These images and more are featured in a paper in the current (10 March 2005) issue of Nature.) Those sure look like coastlines and rivers to my untrained eye. I don't think you'll be wanting to book a vacation on the Titanian coast though. The fluid is almost certainly liquid methane (CH4).
