It's one of the most dazzling displays on Earth.
The northern lights or, if you want to get technical, Aurora Borealis, are one of the most beautiful displays on Earth. It's an incredible show of dancing green lights with the occasional appearance of blue, yellow, and red.
The lights are caused by a cosmic collision between between electrically-charged particles released from the sun that enter the earth's atmosphere and meet with gases such as oxygen and nitrogen.
The lights have been mythologized all over the world. The ancient Greeks believed it was caused by Aurora, the sister of Helios and Seline (the sun and moon), racing across the early morning sky in her multi-colored chariot.
