The Hessdalen Light
Unusual Light Phenomenon Often Executing Breakneck Maneuvers

For generations mysterious lights have been observed in the remote valley of Hessdalen, Norway. On several occasions flying beneath treetops at varying speeds.

The phenomenon has been reported as large as a house or as small as a soccerball. Often executing breakneck maneuvers, or heading for outer space with speeds up to 20,000 mph.

The Hessdalen Light is unexplained light (a type of will-o'-the-wisp) usually seen in the Hessdalen valley in the municipality of Holtålen in Sør-Trøndelag county, Norway.

Unusual lights have been reported here since 1940s or earlier. Especially high activity of Hessdalen lights took place from December 1981 until the summer of 1984 when lights were observed 15 to 20 times per week.

The frequency of the lights caused a gathering of numerous tourists staying there overnight to see the phenomenon. Since then, the activity has decreased and now the lights are observed some 10 - 20 times per year.

The Hessdalen light most often is a bright, white or yellow light of unknown origin standing or floating above the ground level.

Sometimes the light can be seen for more than one hour. There are several other types of unexplained lights observed in the Hessdalen valley.

Since 1983 there has been ongoing scientific research often nicknamed "Project Hessdalen", initiated by Dr. Erling Strand. In 1998, the Hessdalen AMS automated scientific research station was built in the valley.

It registers and records the appearance of lights. Later, the EMBLA program was initiated. It brings together established scientists and students into researching these lights.

Leading research institutions are Østfold University College (Norway) and the Italian National Research Council.

In spite of on-going research there is no convincing explanation to the origin of these lights. However, there are numerous working hypotheses. One explanation attributes the phenomenon to an incompletely understood combustion process in the air involving clouds of dust from the valley floor containing scandium.

Some sightings though, have been identified as misperceptions of astronomical bodies, aircraft, car headlights, and mirages. One recent hypothesis suggests that the lights are formed by a cluster of macroscopic Coulomb crystals in a plasma produced by the ionization of air and dust by Alpha particles during radon decay in the dusty atmosphere.

Several physical properties (oscillation, geometric structure, and light spectrum) observed in Hessdalen lights phenomenon can be explained through the dust plasma model. Radon decay produces alpha particles (responsible by helium emissions in HL spectrum) and radioactive elements such as polonium.

Hessdalen is the only know site on the planet that has a 24/7 observation facility for monitoring and assessing this extraordinary phenomenon, paid for by public support and a Norwegian University.

Scientists from around the world come here to learn about the phenomenon. It is this kind of open-minded international scientific collaboration that the world needs; to delve into the unknown and use science to discern what it is we are observing.

In 2004, Teodorani showed an occurrence where a higher level of radioactivity on rocks was detected near the area where a large light ball was reported.

In fact, when radon is released into air, its solid decay products readily attach to airborne dust.

A new computer simulation shows that dust immersed in ionized gas (i.e., dusty plasmas) can organize itself into double helixes.

The simulations suggested that under conditions commonly found in space, the dust particles first form a cylindrical structure that sometimes evolved into helical structures.

Along some spirals, the radius of the helix was seen to change abruptly from one value to another and then back again, providing a mechanism for storing information in terms of the length and radius of a section of a spiral.

Hessdalen Lights may take the helical structure. Surprisingly, dusty plasmas may also assume this structure.

Another hypothesis explains HL as a product of piezoelectricity generated under specific rock strains because many crystal rocks include quartz grains which produce an intense charge density. In recent paper, based in the dusty plasma theory of HL, it is suggested that piezoelectricity of quartz cannot explain a peculiar property assumed by the HL phenomenon – the presence of geometrical structures in its center.
