Sunlight shining through clouds, giving rise to crepuscular rays over Lake Hāwea, New Zealand. Crepuscular rays, sometimes colloquially referred to as god rays, are sunbeams that originate when the Sun appears to be just above or below a layer of clouds, during the twilight period. [1]
Crepuscular rays as seen from Taipei, Taiwan (2018) Crepuscular rays or god rays are sunbeams that originate when the sun is just below the horizon, during twilight hours. [3] Crepuscular rays are noticeable when the contrast between light and dark is most obvious. Crepuscular comes from the Latin word "crepusculum", meaning twilight. [4]
Crepuscular rays can also occasionally be viewed underwater, particularly in arctic areas, appearing from ice shelves or cracks in the ice. Also they are also viewed in days when the sun hits the clouds in a perfect angle shining upon the area. There are three primary forms of crepuscular rays [citation needed]:

Crepuscular rays, in atmospheric optics, also known as sun rays or God's rays, are rays of sunlight that appear to radiate from a single point in the sky. These rays stream through gaps in clouds, or trees or other objects. The rays are beams of sunlit air, which are separeted by dark shadowed regions.

Anticrepuscular rays, or antisolar rays, [1] are meteorological optical phenomena similar to crepuscular rays, but appear opposite the Sun in the sky. Anticrepuscular rays are essentially parallel , but appear to converge toward the antisolar point , the vanishing point , due to a visual illusion from linear perspective .
