Parts of the US may see aurora borealis Friday night, with rare views of the northern lights possible in places like Illinois and Colorado. I guess that makes up for the Polar Vortex? The gorgeous bands of light are regularly seen in places like Norway and Greenland, but solar flares on Tuesday sparked the possibility of views in America, too. "Aurora borealis," which means "dawn of the north," refers to the lights in the northern hemisphere, but the physical phenomenon happens in the southern hemisphere, too, where it's referred to as aurora australis. In both regions, striking colors span across the sky, making for incredible views and beautiful photo ops. In anticipation of tonight's possible viewing, take a look at some of the most gorgeous photos of the northern lights through the years.
