Crepuscular rays are columns of sunlit air, streaming through gaps in clouds or other objects (for example, mountain peaks). Darker cloud-shadowed regions lie between the sunlit columns. These rays are really parallel to each other. But they appear to diverge, much as a road that looks narrow in the distance appears wide beneath your feet. This beautiful photo of a winter sunset over the Gulf of Mexico shows them clearly.
