The Dark of the Moon

image by Quentin Déhais, Normandy, France

When I first glanced at Quentin's image of a plane in the same field as the Moon I thought that LPOD has had enough of these and there is nothing new to say. And I thought that I'd need to lighten the Moon if the image was used. But then I realized that the Sun is shining on both the plane and the Moon, and thus the Moon really is dark. Of course, I know that. The Moon's average albedo or reflectivity is only 11%, which is a pretty deep gray. But knowing it and viscerally understanding are different; this image dramatically illustrates it.
