At www.jpl.nasa.gov/news/news.cfm?release=2012-048&cid=release_2012-048 there is some interesting information available about Saturn's moon, Titan, the subject of a number of papers in the science press recently. The Cassini spacecraft has beamed back some wonderful images and has shown how Titan's atmosphere resembles that of the earth - with clouds, rainfall, and river valleys, lakes and other geological characteristics that have surprised astronomers to a certain degree.
