Aurora borealis is a luminescence in the atmosphere. In ancient times flashes of cold fire were considered as words of gods, their fiery dance in the northern sky. The scientific explanation of appearing of these beautiful lights relates to the solar wind and Earth's magnetic field.
The aurora has different visual forms - stripes, rays, arcs, and twists through which we can see the stars. This atmospheric phenomenon, similar to long colorful curtains in the sky, may extend for thousands of kilometers from west to east. The lower edge of the aurora is usually sharp and clear, while the top edge is blurred. We always enjoy these spectacular shining views, continuously and rapidly changing, with the rich color spectrum.
