Aurora Borealis

Aurora Borealis / Northern Lights: 1000 years ago people have been very frightened, if they saw an Aurora Borealis, because there were no science to explain the phenomena. They had the anxiety, that some evil Gods might plan an attack. At least they thought, the light in the sky could be the mirrored reflection of a swarm of herrings in the sea – as ironically reported by the German physician G. C. Lichtenberg (1742-1799). Today we know, it’s a geomagnetic storm caused by solar wind. The results could be: some handy phones will disturbed, maybe an airplane’s navigation if on low altitude over the North Pole. Pilots usually change the route more to south. Let`s be thankful, that we have modern sciences and do not need anymore religious speculations about Gods, devils, angels or UFO’s coming from Mars. Sometimes science gives more peace to the mind than any superstition.
