Northern lights light up Calgary sky
Calgary residents were treated to a spectacular aurora over night on Thursday, after the astronomical phenomenon put on a spectacular show.
While most of the world slept, a vivid aurora borealis sent purple, pink, teal and green hues dancing and shimmering across the sky.
The sight of northern lights reduced adults to gleeful children.
The lights are created by charged particles that emanate from the sun, move through space and hit the Earth’s atmosphere, according to Frank Florian, the director of planetarium and space sciences at the Telus World of Science in Edmonton in Canada.
