Sunlight Near the North Pole
This image was taken with an extremely high incidence angle, indicating that the depicted surface is close to the terminator. Unlike a low incidence angle, at which color observations are optimal, a high incidence angle highlights surface morphology. The image was taken relatively near the north pole of Mercury, a region that receives little sunlight.
