Hessdalen rose from obscurity in December 1981 to become one of the most talked about places in Norway and beyond.

Hessdalen is a valley in central Norway. It lies southeast of Trondheim and about 30 kilometres northwest of the town of Roros. The whole valley stretches 12 kilometres in length and has only around 200 inhabitants.

In December 1981, a number of unknown lights appeared in the skies above Hessdalen. Sometimes they would move about at a fast rate of speed, and other times simply hover motionless for hours.

What makes this more unusual than similar lights, like the Paulding or Brown Mountain lights, is that these are sometimes caught on radar. In one case, an orb of light was tracked as it travelled more than 8 500 meters per second.

The vast majority of these lights are seen within the valley, below the mountain ridges around. There are three main shapes that are reported by witnesses: bullet shaped, football shaped and inverted xmas tree shaped. The colours vary from white to yellow and even red.

The sightings continued until the winter of 1983 when observations dropped off drastically. However by the following year, reports were again on the incrase.

In 1983 Project Hessdalen was established to investigate the lights. Fifty-three light observations were made during the 1984 field investigation. In 1985 none were spotted when equipment has been deployed and now 20 observations a year are reported.

In the spring of l994 a group of 20 scientists attended a workshop in Hessdalen which lasted for four days. These included Professor Boris Smirnov from the Institute of High Temperatures in Moscow, Russia, Professor David Fryberger from the Stanford Linear Accelerator in the USA, and Professor Yoshi Othsuki from Waseda University in Japan.

All the scientists agreed that the Hessdalen lights were “real” and not illusions of any kind and that they were worthy of further scientific study.

In 1997 another private non-profit group called ‘The Triangle Project’ was set up to work closely with Project Hessdalen to investigate the lights.

The lights have been observed as recently as January and May of 2010. On January 11, late at night, an object hovered lit up like a Xmas tree as it soared overhead before disappearing into the night. In May a massive light was observed hovering stationary in the sky before moving away and vanishing.

Some theories put forward by individuals over the years have been:

– Car headlamps
– Light from the train
– Airplanes
– UFOs (aliens)
– Sun lights – high speed solar wind streams (Kind of Northern Lights)
– Lights from planets, meteorites,light rain
– Magnetic fields
– Electron density
– Ionized dust from the valley floor

None of these theories has been proven, which keeps the lights a complete mystery.

Below is a fascinating documentary in 5 parts about the Hessdalen Lights:
