This colorized radar image, taken by NASA’s Cassini orbiter on February 15, 2005, shows a 60-km (37-mile) wide crater on Titan. The appearance of the crater and the extremely bright (hence rough) blanket of material surrounding it is indicative of an origin by impact, in which a hypervelocity comet or asteroid, in this case, roughly 5-10 km (3-6 miles) in size, slammed into the surface of the moon. The bright surrounding blanket is debris, or ejecta, thrown out of the crater. The asymmetric appearance of this ejecta blanket could be an effect of atmospheric winds associated with the impact itself. Although clearly formed by impact, the feature lacks a central peak, suggesting that it has been eroded or otherwise modified after formation. Rainfall, wind erosion, and softening of the solid material in which the crater formed are all possible processes that might have altered this impact feature. Image credit: NASA / JPL-Caltech / ASI.
