Not to be mistaken for Northern Lights, these bright colorful stripes are called Light Pillars. They form during cold weather when plate shaped crystals float horizontally close to the ground. These crystals reflect the light coming from unshielded artificial light source (also known as light pollution) and make the light appear as if it was coming from the sky.
