Within the 440-mile-wide Rembrandt impact basin on Mercury we find radiating fractures extending across a central plain and a younger sharp-edged crater, the tip of its central peak peeking into the sunlight.
This impact basin was discovered by the MESSENGER spacecraft in October of 2008. It is one of the youngest impact basins on Mercury, although that may still mean it is over 4 billion years old.
The angle of the sunlight in the image above helps accentuate the topographic features of the basin floor. The photo was taken on September 29, 2009. I rotated it 90º…north on Mercury is to the right.
