Fresh and Bright Canuleia
This image from NASA's Dawn spacecraft features the distinctive crater Canuleia on the giant asteroid Vesta. Canuleia, about 6 miles (10 kilometers) in diameter, is distinguished by the rays of bright material that streak out from it. There is also a more subdued unnamed crater of about the same size to the northeast. A comparison of these two craters illustrates how freshly excavated materials on Vesta appear quite different from background soils.
The image was taken by Dawn's framing camera on Oct. 20, 2011, from an altitude of about 420 miles (680 kilometers).
