A light pillar or ice pillar is an atmospheric optical phenomenon in which a vertical beam of light appears to extend above and/or below a light source. The effect is created by the reflection of light from tiny ice crystals that are suspended in the atmosphere or that comprise high-altitude clouds (e.g. cirrostratus or cirrus clouds). [1]
Meteorologist Alex O'Brien explains the science behind how light pillars occur and why they have been appearing in the sky recently. Light Pillars in nighttime sky explained [Video] Skip to main ...
A light pillar, or sun pillar, appears as a vertical pillar or column of light rising from the Sun near sunset or sunrise, though it can appear below the Sun, particularly if the observer is at a high elevation or altitude. Hexagonal plate- and column-shaped ice crystals cause the phenomenon.

Diffraction of light through the eyelashes; Haidinger's brush; Monocular diplopia (or polyplopia) from reflections at boundaries between the various ocular media; Phosphenes from stimulation other than by light (e.g., mechanical, electrical) of the rod cells and cones of the eye or of other neurons of the visual system; Purkinje images.
Light rays coming from the zenith take the shortest-possible path (1 ⁄ 38) through the air mass, yielding less scattering. Light rays coming from the horizon take the longest-possible path through the air, yielding more scattering. [11] The blueness is at the horizon because the blue light coming from great distances is also preferentially ...
Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun. They can be seen anywhere in the world during any season, but are not always obvious or bright.
