Only in the fleeting darkness of a total solar eclipse is the light of the solar corona easily visible. Normally overwhelmed by the bright solar disk, the expansive corona, the sun’s outer atmosphere, is an alluring sight.

But the subtle details and extreme ranges in the corona’s brightness, although discernible to the eye, are notoriously difficult to photograph. Pictured above, however, using multiple images and digital processing, is a detailed image of the Sun’s corona taken during the 2008 August total solar eclipse from Mongolia.
