The aurora borealis is a natural atmospheric phenomenon that consists of multicolored lights visible to the naked eye in polar zones.

The aurora are produced when electrically charged solar particles become trapped at the polar regions by the earth's magnetic field. When these solar particles come into contact with atmospheric gases, they produce light particles called photons which, in large quantities, become visible to the naked eye. -
