This image features a very fresh crater in the Southern hemisphere. The crater is termed fresh because it is well-preserved with steep walls and obvious small-scale ejecta.

The crater has a set of dark rays extending from it; these rays are ejecta that sprayed out when the crater formed. Boulders ejected during the impact surround the crater.
