The Northern Lights, or the Aurora Borealis. The Vikings thought it was a road to the Gods, but we now know exactly what those beautiful lights actually are.


If the people of Wisconsin can get away from city lights this weekend, there's a chance there'll be northern lights to take in.

The National Oceanic and Atmospheric Administration expects a geomagnetic storm to peak late Saturday and early Sunday, meaning northern lights — aka aurora borealis — could be visible in high-latitude areas across the U.S., including northern Michigan and Maine. 

The forecast indicates some of the action could be visible in the northern half of Wisconsin. 

Aurora borealis are caused by electrons colliding with the upper reaches of Earth's atmosphere. There's an energy release in the form of light. In best-case scenarios for onlookers, splashes of pink, green, yellow, blue and violet fill the night sky. Here's a longer explanation from the NOAA.

The best place to go to see the light is away from cities and other sources of light pollution. Basically, the farther you are from clusters of light — whether from streets, businesses, homes or other sources — the better your odds at catching a glimpse.
