The Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermosphere, the outermost actual atmosphere. Above this layer, the exosphere has so few molecules that they can escape into space.(see the related question below)

Charged particles from the Sun striking the upper atmosphere.
In the upper mesosphere and the lower thermosphere, gas particles become electrically charged. Because these charged particles are called ions, this part of the thermosphere is called the ionosphere. In polar regions these ions radiate energy as shimmering lights called auroras, usually in latitudes above 50 degrees.

The "Northern Lights" (or Aurora Borealis) and their southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermosphere, the outermost actual atmospheric layer. Above this layer, the exosphere has so few molecules that they can escape into space.(see the related question below)

1. The lowest part of it is higher then a jet plane flies. 2. It is considered a natural light
Aurora borealis is caused by collisions between gaseous particles.
Aurora Borealis.
One consequence is increased ionization of earth's upper atmosphere. The good part of that is spectacular displays of the aurora borealis. The bad part is increased radio, telephone and satellite interference.
The aurora borealis is the closest thing to "nothing" that you can actually see; it is VERY thin air, partially ionized by the solar radiation spiraling in toward the Earth along the magnetic field lines. It is, for the most part, above the highest altitude that aircraft can reach. If you were to go up in a high-altitude balloon and jump out with a space suit and a parachute, you could "fall into the aurora borealis" and suffer no ill effects. Without the space suit, you would be dead in moments from lack of air, and without a parachute, you would be killed on impact with the ground 30 miles below.
The upper part of the thermosphere is called the Ionosphere A+ Magnetosphere
Anders Celsius took part of an expedition to verify Isaac Newton's theory that the world was not actually a perfect sphere. He and his assistant discovered that the aurora borealis influenced compass needles.
