Hessdalen Lights
The quaint country of Norway has experienced something crazy in its skies. Sometimes, there are floating streaks of light that take the colors of white, yellow, and even red. They appear over the Hessdalen Valley, hence the name, and remain in the sky for nearly two hours.
The lights have been appearing since the 1930s. Researchers believe that ionized iron dust causes the lights in the skies, but it's hard to tell. It's basically a form of an aurora borealis, but even more peculiar.
