Photos of Aurora Borealis hide horrible faces and arouse netizens' recollection of September 11

Sihai science and technology channel, November 19 - a recent photo of the northern lights captured by a photographer in Iceland has aroused a lot of speculation among netizens. Because there is a terrible face in the photo, many netizens have also taken out the famous Satan's smile in the September 11 incident for comparison. Although there is no necessary connection between the two, this strange natural phenomenon has attracted the attention of fans and scholars.

Aurora Borealis is a colorful luminous phenomenon that appears over the high magnetic latitude region of the planet's North Pole. The aurora of the earth is produced by the excitation (or ionization) of molecules or atoms in the upper atmosphere by the high-energy charged particle stream (solar wind) from the earth's magnetosphere or the sun.
