February 18, 2009--Remarkably tall artificial light pillars are seen in Ontario, Canada, in January 2004 in this composite panoramic photo.

When the photographs were taken, the temperature hovered around -11 degrees Fahrenheit (-24 degrees Celsius), and the air was very still, with a gentle drizzle of ice crystals falling from the sky, according to photographer Lauri Kangas.

Extreme cold contributes to the formation of light pillars, which can be caused even by light from car headlights.
