Northern lights over the mountains in Norway.

The peculiarity of the northern lights is that which is never the same. Ribbons, spots, stripes are blurred and transformed again, becoming clearer and brighter. The color of the aurora depends on what parts of the atmosphere the solar wind passes through, for example, the nitrogen is colored violet, the oxygen is green and red.
