NASA MESSENGER: The Van Eyck crater on Mercury

Low sun elevation creates long shadows in and around Van Eyck crater on Mercury. 

This image obtained by MESSENGER spacecraft shows how material ejected from the Caloris basin has cratered the rim of Van Eyck. 

The smooth plains making up the floor of Van Eyck also show the scars of cratering, ranging from large primary impacts to deep, linear incisions by secondary crater chains. 

Jan Van Eyck, a Flemish painter, lived from about 1390 to 1441 CE.
