Titan Radar Image: Multi-Ring Impact Basin

Here is a RADAR image showing what appears to be a giant impact basin on Titan. This basin, 440 km wide using the outer diameter, is one of the first definitive craters on Titan. Previously, no craters had been found, or if a circular feature was found, a different origin was found to be more likely (viscous volcanism or calderas). The circular feature seen here has been by ISS and can be seen as the bright/dark annulus toward the upper right in the image below.
