In this composite photograph, the northern lights, or aurora, reflect off Jökulsárlón, a glacial lake in Iceland. Photographer Stephane Vetter stitched together six photographs to make this image, which reveals the band of the Milky Way galaxy, the Pleiades star cluster and the Andromeda Galaxy in the night sky. The photo took first place in 2011's Second International Earth and Sky Photo Contest. Credit: Stephane Vetter
