The Moon’s hidden southwest corner


Damian Peach from Hampshire, U.K.

Favorable libration briefly tilts the Moon’s southwestern limb into view in this image, exposing three heavily foreshortened craters: Bailly (center left) at roughly 180 miles (300 kilometers) across; the well-preserved Hausen (upper left); and 149-kilometer Drygalski (upper right), so close to the limb it is normally hidden entirely, and lies close to the permanently shadowed regions of the lunar south pole.
