LIGHT PILLARS-STUNNING COLUMN IN SKY

Optical phenomena are any observable events that result from the interaction of light and matter. A mirage is an example of an optical phenomenon. Common optical phenomena are often due to the interaction of light from the sun or moon with the atmosphere, clouds, water, dust, and other particulates.

Generally seen in cold, arctic regions, light pillars are an optical phenomenon where columns of light can be seen emanating from below or above a light source. Light pillars occur when natural or artificial light reflects off flat ice crystals in the air close to the Earth's surface. Sun pillars or light pillars are formed by reflection from hexagonal plate-like ice crystals in Earth's air. These crystals drift through the atmosphere with a horizontal orientation, gently rocking from side to side as they fall. They are falling through Earth's atmosphere, rocking slightly from side to side.
