  Several theories have been made based on research work by 
different kind of persons, both students, hobby amatours and scientific person. Many of them 
are so called non-ufologists, and they have an open approach to find 
out what the phenomena really is. 
The Hessdalen phenomena varies both in shape, movements and colours and time 
when it occurs. 
According to Project Hessdalen (www.hessdalen.org) the phenomena can be 
organised in four different types: 
1. White, or blue-white flashing light. 
2. A yellow light, with a red light on the top. 
3. A yellow or white light. 
4. A black "object" with light on. 
Some of the theories are: 
- 
Locals who live in the fantasy 
world (for many years people from outside the village wouldn`t believe the 
incredible stories, but some are still sceptical) 
- Car 
headlamps 
 
  - Light from the train 
- Airplanes 
  - UFOs (aliens) 
- Sun 
lights - high speed solar wind streams 
- Lights from planets - meteorites - 
light rain 
- Kind of Northern Lights 
     - Magnetic fields 
- Electron 
density 
- Etc. 
Or could it be an 
combinition of these theories that could make the ultimate conclusion? 
       
        
For us in Travel Explorations it only seems that the mystery in Hessdalen 
grows bigger day for day, but we hope that all the experts and the advanced 
scientic equipment can solve the Norwegian riddle in the sky.
