A new type of polar light has been discovered

New one a study Reports indicate that it represents a new type of light phenomenon in the atmosphere University of Iowa website. When analyzing an image spanning nearly two decades, the researchers noticed that the diffused polar light – the faint accompaniment of the bright and striking aurora – darkens in several places and then shines again. According to the team, no similar person has been presented in the literature before.

Polar lights are formed when charged particles from the sun interact with the Earth’s magnetic field. Some particles can make their way through the shield and collide with the gas in the atmosphere, creating a glow. Team member Alison Gaines said the question is whether the type they’ve noticed is common. The researcher believes that it is conceivable that the phenomena are the result of a process that has not yet been studied.

On March 15, 2002, David Knudsen, a physicist at the University of Calgary, captured the polar lights at Churchill in Hudson Bay. The conditions weren’t very conducive to surveillance, but he did make videos. When analyzing his recordings, Knudsen later noticed a strange pulse as well. The video and accompanying notes were forgotten for a while until Jaynes passed them on to one of his students, Riley Troyer.

Troyer began scanning the video with special software and spotted a total of 22 moments when the new phenomenon was visible. Experts don’t yet know what causes the fading or glare in the diffuse polar light.
