Aurora Borealis: A new phenomenon discovered in the Northern Lights

Space researchers have revealed that stargazers and amateur photographers have recently captured a new form of the Northern Lights, or the so-called Aurora Borealis. The phenomenon of bright green lights rippling across the night sky has fascinated the public and experts alike. Some have suggested depicting the lights in prehistoric cave paintings, while the astronomer Galileo Galilei should have coined the Latin term.

The northern polar lights are created when the sun ejects charged particles, such as electrons, and directs them through the magnetic field of our planet to the earth's poles. There they interact with gases in the atmosphere, including oxygen and nitrogen, and increase the energy of these gases. Accordingly, this energy is then released as light.

It is believed that the phenomenon that its discoverers call “dunes” comes from waves of oxygen atoms that glow due to the particles released by the sun. In the recently published study, the scientists attributed the origin of the dunes to a waveguide. This has formed within the mesosphere and its boundary, the mesopause. The study also believes that this new form by Aurora Berealis researchers offers a new way to study conditions in the upper atmosphere.

Amateurs have taken thousands of great photographs of the Northern Lights so far. Scientists measured these and categorized them for the book. Each shape is like a fingerprint that is only typical of a particular phenomenon in the zone. During the classification, hobbyists indicated that a particular formation did not fit into one of the existing categories.

By an almost incredible coincidence, the photographers saw this unusual shape again a few days after the book was published. They immediately informed the space researchers. The phenomenon appeared as a greenish and even wave pattern that resembled a striped veil of clouds or dunes on a sandy beach. Investigations into these phenomena were started, with hobbyist observations combined with scientific methods and studies to explain the waves.
