Light Pillars: What Are Those Mysterious Light Beams From The Sky?

Light pillars are optical phenomena visible in extremely cold temperatures when ice crystals form in the atmosphere. These crystals reflect light from sources like street lights, the sun, or the moon, creating vertical columns of light. The phenomenon is an illusion, not a physical beam, and occurs mainly in Arctic regions but can also be seen in other cold areas. Light pillars vary in color based on the light source. They are related to other phenomena like sun pillars and sun dogs, which also involve ice crystals. Despite their appearance, light pillars are not evidence of UFOs but a natural spectacle.
