Tour guide and photographer, Oliver Wright, recorded an unusual sound in the north of Sweden, which resembles the noise that makes the gun from “Star Wars”. He believed that the sound was caused precisely by Northern Lights.
Wright, who works as a guide at “Lights Over Lapland”, heard the unusual noises when he led a group of people at Christmas to see the phenomenon of “Aurora Borealis” in Northern Sweden.
– “I stood under the intense display of aurora when I heard that noise”, he told the Spaceweather.com.
He claimed his first cause was that the sound might coming from the transmission lines in the vicinity, and that the people around him also heard the same noise. Then, as he said, he approached the pylons and recorded the sound on his smart phone.
Wright says that the noise intensified as he was approaching the pylons and decreased as he get away. He added that in his previous tours he has already heard the same noise, but now he recorded it for the first time.
But Oliver is not the only person who is interested in the sounds of the Northern Lights. Throughout history, people often spoke of these sounds, describing them as cracking, noise, hum or whistle. Danish researcher Knud Rasmussen indirectly mentioned them in 1932, speaking about folk customs of the Greenland Eskimos, as well as the Canadian anthropologist Ernest Hawks back in 1916. Cornelius Tacitus, historian of ancient Rome also wrote that the people of the north claimed to have heard the same sort of noises.
There are various theories about local electrostatic phenomena on the ground arising as a result of the Northern Lights and so far they best describe the origin of these unusual sounds, but scientists still disagree about the origins of these mysterious sounds.
Today are still arriving reports of sounds of Northern Lights, but so far scientists believed that it was unbelievable for any sound to be produced in Aurora and the same to be able to come to the ground, because the sound would have been taking a long time to arrive.
This means that these particles or geo magnetic disturbance which produce the sound is much closer to the ground. Finnish researchers from Aalto University few years ago located that the sounds associated with the northern lights occur at about 70 meters above the ground. Researchers have located the sources and have installed three separate microphones in places where the sounds of Northern Lights were recorded. Then they compared the sounds and determined the location of the sound source.
However, most details of how really sounds the Northern Lights still remains unsolved.
