Cassini Spies Possible Lake on Saturn's Moon Titan
Could Saturn's moon Titan be a land of lakes? A new image captured by the Cassini spacecraft indicates that it just might -- though the possible lake in question could be filled with liquid methane rather than water, NASA said on Tuesday, June 28, 2005. The putative lake appears in a Cassini image of Titan's south polar region, a well-defined but irregularly shaped dark spot with smooth, shore-like boundaries unlike anything previously seen on this Saturn satellite.
