This week, the moon will continue its trip across the evening sky as it waxes towards Friday’s Full Frost Moon. Pull out your binoculars and telescopes and take a look! Low-angled sunlight will illuminate peaks and crater rims while casting deep black shadows from them. It will also reveal subtle topographic features that are otherwise invisible, such as ridges and cracks on crater floors. New sections of the moon will be highlighted every night as the terminator, the boundary line that separates the lit and dark hemispheres, migrates from lunar east to west.
