Around the central area of Moon, the crater of Copernicus is well-proportioned one with a diameter of 93km positioned at the southern edge of Imbrium, MARE (Sea of rain). You can detect three central peaks in it and can see white stripes spread out from the crater during near full moon, called "ray". In addition to Copernicus, the ray can be seen around the Tycho in southern mountainous region. Although the origin of ray is considered the scattered matter of collided meteorite, detailed cause hasn't been known yet.
