The World’s 14 Most Mysterious Places.
Hessdalen Lights, Norway – Researchers can at least touch, examine, measure and revisit monoliths, sculptures and stone spheres, even if they remain mysterious. They can’t do the same with the as yet unexplained eerie lights that appear periodically in the Norwegian Hessdalen Valley. Sightings of unusual, colourful moving lights in the night sky were already reported a century ago, possibly even earlier, but reports peaked in the 1980s. Since then, Project Hessdalen has been monitoring the lights, and since 1998 an Automatic Measurement Station (AMS) has been documenting occurrences, capturing photographic evidence and trying to find scientific explanations. The fact that, almost 20 years later, they still haven’t arrived at a satisfactory conclusion is all the proof some UFO theorists need that extraterrestrial activity is to be blamed. hessdalen.org
