Hessdalen Lights and the Unsolved Mystery of Norway’s Skies
You might spot the Hessdalen Lights as glowing light balls in Norway’s skies. These unexplained lights appear without warning. Some appear small, others stretch up to 30 meters. Thus, their shapes can shift, sometimes glowing brightly, and at other times forming rectangles. The Hessdalen Lights often move in strange ways, even oscillating. Moreover, you find them in a quiet valley, far from busy cities. Scientists link their light to helium emissions and higher radioactivity in the area. The mystery continues to draw curious minds, prompting you to question what you see.
Hessdalen Lights
Appearance
Color and Shape
You might spot the Hessdalen lights as glowing orbs or balls. Most often, you see them in white or yellow. Sometimes, they look shiny and solid. Other times, they stretch into cylindrical shapes. These lights can appear small, like a soccer ball, or grow up to 30 meters long. Further, you may even notice a green tint in rare cases. Scientists say these lights sometimes leave traces of radiation behind.
- Common colors: white, yellow, and sometimes green
- Shapes: orbs, balls, and cylinders
- Size: from decimeters to 30 meters
The Hessdalen lights stand out from other natural lights. They do not look like the northern lights. Instead, they appear as strange balls of light that float or move quickly across the sky.
Movement
The movement of the Hessdalen lights will surprise you. Sometimes, they hover in one spot. Other times, they shoot across the sky at high speeds. Scientists have measured speeds up to 20,000 meters per second. Hence, the lights can move horizontally, vertically, or even in zigzag patterns. Moreover, you might see them split into two or change color as they move.
- Hovering in place
- Sudden, fast movements
- Changing direction without warning
- Splitting into smaller lights
- Touching the ground without burning it
The Hessdalen Automatic Measurement Station (AMS) keeps watch day and night. Additionally, it uses cameras, radio receivers, and sensors to track these unpredictable movements. Sometimes, the lights show up on radar even when you cannot see them. The AMS streams live data, so researchers can study the lights in real time.
Location
Hessdalen Valley
You find the Hessdalen lights in a quiet part of central Norway. Indeed, the Hessdalen Valley is famous for these glowing lights. The valley stretches about 12 kilometers. Additionally, it has a unique microclimate and special geology. Some scientists think the valley acts like a giant battery, helping to power the lights. The area does not need storms for the lights to appear. Certainly, you can see them in clear weather or cloudy nights.
The Hessdalen lights have appeared here for decades. People from all over the world visit the valley to watch the lights dance in the Norwegian night sky.
Observation Area
The main observation area covers several kilometers. You can stand on hills, mountain ledges, or near Lake Oyungen to watch the lights. Groups often spread out about 2.5 kilometers apart to get the best view. The lights move slowly at times, lighting up the ground below. You might see them from Heggsethggda Hill, Varhuskjglen Hill, or Fjellbekkhggda Mountain. The area has no set borders, but most sightings happen within this 12-kilometer stretch.
- Multiple vantage points: hills, valleys, and lakes.
- Lights seen from different angles and distances.
- No fixed boundary for sightings.
Mysterious Phenomenon
Unpredictable Behavior
You never know when the Hessdalen lights will appear. Sometimes, you see them for just a few seconds. Other times, they linger for over an hour. Basically, the lights can show up in any season. You might spot them in the middle of winter or on a summer night. They do not follow any clear pattern. Thus, this makes the phenomenon hard to predict.
The lights can change color and shape without warning. One moment, you see a glowing orb. Next, it stretches into a long cylinder. Sometimes, the lights split into two or more parts. You may even see them move in zigzags or hover in one spot. Therefore, this unpredictable behavior adds to the mystery. Many people try to track the phenomenon, but it always surprises them.
Distinct from Aurora
You might think the Hessdalen lights look like the northern lights. However, they are very different. Here’s how this phenomenon stands out:
- Firstly, you can see the Hessdalen lights both day and night. Auroras usually appear only at night.
- The lights can hover, move fast, or change direction. Moreover, auroras flow slowly across the sky.
- Hessdalen lights show colors like white, yellow, red, and green. Auroras have more common color patterns.
- Sometimes, you see clusters or double helix shapes. Hence, auroras do not form these geometric structures.
- The phenomenon may come from local geology. Similarly, some ideas include burning dust with rare elements, plasma from radon decay, or electric charges from quartz rocks.
- The lights move at speeds up to 20,000 meters per second. Auroras do not move this fast.
- Scientists find radioactive elements and ionized dust in the area. Hence, this is unique to the Hessdalen phenomenon.
Sightings History
Early Reports
You might think the Hessdalen Lights started recently. Actually, people in the valley noticed strange lights as early as December 1981. Locals described a “burning fireball” in the evening sky. Some saw the lights close to their homes. Others spotted them high above the ground, but always below the mountain tops.
- The lights appeared in many forms:
- Small, strong white or blue flashes.
- Secondly, yellow or yellow-white lights, sometimes stationary and sometimes moving fast.
- Groups of lights, often with two yellow or white and one red in front.
You could see these lights anywhere—above roofs, near the ground, or in the sky. Sometimes, they stood still for over an hour. Other times, they moved quickly, even up to 8,500 meters per second. Indeed, the lights made no sound. Photographs showed bullet-shaped, round, or even upside-down Christmas-tree shapes. Mostly, glowed white or yellow-white, but some flashed red, green, or blue.
1980s Surge
In the early 1980s, you would have noticed a big change. Sightings increased a lot. Sometimes, people saw the lights many times each week. Thus, this surge happened because more people paid attention. Scientists and journalists visited the valley. Additionally, they brought cameras and radar. News spread quickly. Hence, more eyes watched the sky.
A journalist who doubted the lights changed his mind after seeing them himself. He even took photos. The valley’s unique minerals—scandium, zinc, iron, and copper—may play a role. Some scientists think water in the ground helps create electric currents. Therefore, these currents might cause the lights. Still, the main reason for the surge was more people looking and reporting.
Scientific Interest
You might wonder why scientists care so much. The Hessdalen Lights show up again and again. This makes them different from other strange sky events. In the 1980s, researchers started to document the lights with new tools. They used cameras, radar, and even spectral measurements.
- People in Hessdalen talked about the lights since the 1940s. But real records started in the 1980s.
- Scientists kept coming back because the lights did not stop.
- In 2009, a documentary called “The Portal: the Hessdalen lights phenomenon” brought new attention.
- Norwegian and Italian scientists began to work together.
- Today, you can watch live camera feeds from the valley.
- Researchers have many ideas. Some think the lights are a kind of cold plasma. Others believe the valley’s minerals create electric currents.
- No one has solved the mystery yet. Scientists keep studying, hoping to find answers.
