The photo above shows a fine example of crepuscular rays emerging from the serrated edges of a cumulus congestus cloud. Crepuscular rays form when sunlight is scattered by clouds, dust, haze, or other aerosols to form alternating beams of light and shadow that appear to radiate from a single point. Note also the shadow cast by this same cloud -- just above its sunlit upper edge. Photo taken from near Heathrow, Florida, just before sunset, on November 26, 2006.
