Look to the sky Tuesday, and see the crescent Moon move side-by-side with Pleiades—also known as the Seven Sisters constellation.
The crescent Moon lit by “Earthshine,” as Leonardo Da Vinci called the light of our planet illuminating the Moon’s dark region, has been called one of the most beautiful sites in the heavens. Tuesday marks an especially momentous occasion. This Earthshine will gently illuminate the dark area opposite a 12 percent crescent, and the Seven Sisters will align with the Moon.
For best viewing, look west shortly after sunset, and use binoculars to see the show. The crescent Moon, Earthshine and Pleiades should all be visible in the same field.
