The full Moon

The full Moon

. The near side of the Moon that is always turned toward the Earth. This Earth-based view of the full Moon enhances the consrast between the dark maria and the bright-rayed craters, such as Tycho (near bottom center), named after Tycho Brahe. The dark circular Mare Imbrium (Sea of Rains) is prominent in the northwest (upper left), immediately above the bright rays of craters Copernicus and Kepler (middle left). The dark circular Mare Serenitatis (Sea of Serenity) lies to the east (right) of Imbrium. (Lick Observatory photograph.)
