The image was captured with Cassini’s radar mapper during its January 13, 2007 flyby of Titan. The crater is about 180 km (110 miles) wide, and the bright material around the dark centre is the ejecta blanket hurled out during the impact. The inner crater is dark; for radar images, that means it’s a smooth surface, possibly from deposits covering the inside of the crater.
