Recently named after the 12th century Chinese artist, the Xiao Zhao crater on the central left side of this image is small in comparison with many other craters on Mercury. The fresh, bright rays, which were created during the impact that formed the crater, indicate that Xiao Zhao is a relatively young crater on Mercury's surface. (NASA)
