Description

Night View PosterThis stunning image of the Earth at night is both beautiful and saddening. The clarity of the continents from space is a testament to how light pollution has destroyed our view of the heavens. Also included are views of the Los Angeles Basin as seen from Mount Wilson in 1908 and the present. Use this striking poster to educate others about the loss of our precious natural resource, the night sky. Size: 34"x26"
