On December 9, 2009, a curious spiral of blue and white light appeared in the night sky over northern Norway and Sweden, freaking out a section of the public and generating an intense debate among astronomers and scientists as well as conspiracy theorists. Hundreds of people called the Norwegian Meteorological Institute to ask what it was. Everything from anomalous Northern lights, to aliens and trans-dimensional wormhole was suggested. Some even linked the event to the high-energy experiments that was going on at that time at the Large Hadron Collider in Switzerland. The light was seen from all across northern Norway as well as from northern Sweden, and was reported to have lasted for 10 minutes.
