"Light pillars are an atmospheric phenomena created when tiny ice crystals reflect either natural (sun or moon) or artificial light (such as streetlights)," says The Weather Network meteorologist Erin Wenckstern. "This type of ice crystal is flat and hexagonal in shape, and when they are suspended in the air, together they act like a gigantic mirror, reflecting the light source upwards or downwards."
