Stunning! Aurora Borealis in the Finnish Lapland [Video]

The term aurora borealis means "dawn of the north." Aurora australis means "dawn of the south." These fantastic light displays are produced by collisions between electrically charged particles from the sun as they enter Earth's atmosphere near the magnetic poles, where Earth's protective magnetic field is weakest. In most instances, northern and southern auroras are mirror images of each other that occur at the same time.

This film was shot in Finnish Lapland in 2011.  (H/t: Flatlight Films; Geeks are Sexy; Northern Lights Centre)
