Overview and Evidence[]
The Hessdalen Lights are a group of anomalous lights occasionally sighted throughout the Hessdalen Valley in Norway. They are the focus of Hessdalen AMS (Hessdalen Automatic Measurement Station), an autonomous research station located in the area founded in 1998.[1][2]
The lights are generally described as being white, yellow, or reddish in color. The frequency of appearances is inconsistent, appearing seemingly at any time of day and in any weather conditions. The duration of the sightings is also inconsistent with some manifestations clocking in at over an hour. They also display seemingly random behaviors in terms of the direction and speed at which they move about in the sky.
As with all unidentified lights, those in the Hessdalen Valley have invited all manner of speculation regarding their origins. The obvious conclusions, such as misidentification of car headlights and helicopters or ball lightning, have been suggested. Another popular hypothesis involves a phenomenon called piezoelectricity, in which electrical charges build up in certain phyical materials like minerals when subjected to applied mechanical stress.
