Aurora Borealis arise when electrically charged particles from the solar wind hit oxygen and nitrogen atoms in the upper layers of the earth's atmosphere and ionize them.
They mainly occur in the polar regions of the northern and southern hemisphere, where the magnetic field lines immerse in earth's atmosphere.
Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky.
