To Be Young and Rayed on Mercury
This high-resolution image shows a bright, rayed crater in spectacular new detail; this crater is located just east of another small rayed crater, imaged early in MESSENGER's orbital mission. Both of these craters are considered relatively young features on Mercury's surface, since their bowl-shaped appearance hasn't been modified and their rays haven't yet faded with time. However, keep in mind that on Mercury, features less than about a billion years old are considered to be relatively young!
