Fifty miles above sea level, much beyond the far reaches of the ozone layer, there lies a huge stretch of air called the thermosphere, where temperatures reach up to 2000° Centigrade. Particles in this part of the sky are pretty scarce, yet there is lots of heat to transfer. When particles do collide as they are moved around by the solar wind, they create the stunning display of atmospheric pyrotechnics we call the Aurora Borealis and Aurora Australis, or the Northern and Southern Lights.
This stunning image comes from pastel works by French artist and astronomer Étienne Léopold Trouvelot, for The Trouvelot Astronomical Drawings published in 1882.
