Dimitri Goderdzishvili Shot Extremely Rare Atmospheric Phenomenon Called Light Pillars
These colorful light beams don’t represent any kind of spotlights pointed up in the sky. What’s more, they don’t really exist – they are just an optical illusion.
Hexagonal shaped ice crystals, normally only present in high clouds, float in the air close to the ground and their horizontal facets reflect light back downwards. This is what causes the optical illusion of light pillars. However, coincidence of some more factors is needed to make it happen, such as strong cold and absolutely windless night.
