A vivid display of Northern Lights illuminates the landscape below.
In this composite photo, the phases of a total solar eclipse stretch across the sky.
The total solar eclipse captured at the end of totality, displaying the sun's corona and the beginning of the "diamond ring effect" as the sun beings to reappear from behind the moon. The planet Mercury, which is normally difficult to see because it's so close to the sun, is located near the lens flare southwest of the eclipse.
