Ontario Lacus, a lake near to Titan's South Pole
This view of Titan's south pole reveals the intriguing dark feature named Ontario Lacus and a host of smaller features dotting the south polar region.
The true nature of this feature, seen here at left of centre, is not yet known with absolute certainty. However, the feature's darkness, the shore-like smoothness of its perimeter, and its presence in an area where frequent convective storm clouds have been observed by Cassini and Earth-based astronomers made it the best candidate for an open body of liquid on Titan when this image was taken in June 2005.
