It is a beautiful phenomenon of the emission of light rays without raising the atmospheric temperature known as aurora borealis, it occurs when an expulsion of solar mass collides with the north and south poles of the outer zone of the earth's atmosphere where the aurora arises, a diffuse light projected on the layer of the Earth's atmosphere, composed of proton particles that diffuse color.
It is said that it is boreal when this phenomenon is observed in the middle of the surface of the northern terrestrial sphere and the southern aurora when it is observed in the middle of the southern surface.
The northern and southern aurora can produce different or different colors depending on the inclined direction with which the solar particles collide with a pole.
The sun emanates all kinds of tiny bodies or small parts that some will simply cross the gaseous mass that surrounds a star and collide with the earth, but others can be affected by the earth's magnetic field, so that positive charges will take a destination and the negative charges will take on others.
The disposition of the magnetic field of the earth, both very small body flows or very small parts will reach the opposite poles, to finally collide with the space that surrounds the earth producing all appearance or material or spiritual manifestations of light that we know as aurora borealis..
The discipline that occurs between small bodies or small positive and negative parts, of the same emission of light rays without raising the temperature, almost only in the darkness that occurs at the north pole.
