Polarlicher = Aurora Borealis/Australis
Aurora Borealis/Australis dance as green, red or blue veil on the horizon and can appear and disappear in a moments notice. Marvel with us about the beauty of the Aurora
Aurora Borealis lights dance in green, red or blue, sometimes only for a few seconds.
In northern Finland, one can observe the Aurora Borealis almost 200 nights a year.
The lights appear over 100 KM over the Polar regions of the earth. When the electric particles from the Sun collide with nitrogen and oxygen, the resulting energy will partially been seen as light. Depending on the height of those collisions, they create red, green, or blue-violet.
Galileo Galileo, Born: February 15, 1564, Pisa, Italy - Died: January 8, 1642, Arcetri, coined the phrase Aurora after the Roman Goddess. In the northern hemisphere, the phenomenon is called Aurora Borealis, whereas in the southern hemisphere it's called Aurora Australis.
In the year 37 AD, a flaming red light was seen passing over Ostia, the harbor of Rome. Emperor Tiberius dispatched Legionnaires to put out the conflagration. Alas, it was for naught, the troops only saw the Aurora Borealis (which is very seldom at this latitude).
A Hotel in Finland has an employee since 2016, working form 11:30 PM to 6:30 AM and his sole responsibility is to inform the guests that an Aurora Borealis is in full view.
Explanation:
Bottom line: When charged particles from the sun strike atoms in Earth's atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.
