Photos

Solar eclipse totality [11:49AM MDT]

This photo captures a huge range of light in a single composite image. That's 17.3 stops of dynamic from multiple exposures - or a contrast ratio of 160,000:1 - enough to capture a corona "wingspan" of over 2 million miles. Also captured is illumination of the moon's surface by light reflected from Earth - called "earthshine". The eclipsed sun is flanked by two other visible stars: Regulus on the left, Nu Leonis on the right.
