Summary Author: Bill Curry; Jim Foster
The photo above showing rays of sunlight breaking through a sullen sky was taken after a brief but intense snow squall in Port Maitland, Nova Scotia, Canada. Many people refer to scenes such as this as Jacob’s Ladder or God Rays as the light coming through the clouds does appear as if it's leading one to ascend to heaven. Of course, what we're seeing is sunlight streaming through gaps in clouds in the vicinity of the Sun. They can be seen any time of day but are most noticeable when the Sun is low in the sky or even below the horizon. When observed at dusk or dawn, the rays are appropriately called crepuscular rays (twilight rays). Perspective makes it seem that the rays are fanning out from the Sun (hidden by the clouds), but in fact, they're basically parallel to each other. Photo taken at 4:48 p.m., about 45 minutes before sunset, on January 30, 2012.
