Explanation: 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 [5] , the sun's outer atmosphere [6] , is an
alluring sight. But the subtle details and extreme ranges [7]  in the corona's
brightness, although discernible to the eye, are notoriously difficult to
photograph. Pictured here [8] , however, using multiple images and digital
processing, is a detailed image of the Sun's corona taken during the 2008
August total [9] solar eclipse [10]  from Mongolia [11] . Clearly visible are
intricate layers [12]  and glowing caustics of an ever changing mixture of hot
gas and magnetic fields [13] . Bright looping prominences [14] appear pink
just above the Sun's limb [15] . A similar solar corona might be visible [16]
through clear skies in a thin swath across the USA [17]  during a total solar
eclipse that occurs just one week from tomorrow [18] .
