Tour guide Chad Blakley shot this beautiful time-lapse footage of the aurora borealis (Northern Lights) over the Lapland province of Sweden in February.
The lights typically manifest during the winter months and appear until late March or early April. Their “dance” is caused by the interaction of charged electrons from the solar wind and elements in the earth’s atmosphere. In this case, the green coloration of the Northern Lights means the electrons are interacting with oxygen molecules, up to 150 miles in altitude. (Oxygen can also cause red lights once the electrons climb over 150 miles up.)
Watch the spectacular footage above.
