Northern lights are natural radiations seen in the sky in the polar regions, resulting from the interaction of the Earth's magnetic field and the charged particles from the Sun. In northern latitudes, this effect is called the lights of the north. The formation of the aurora australis (southern aurora) at southern latitudes has similar characteristics; however, it can be seen from higher latitudes in Antarctica, South America, and Australia.Northern lights, usually observed at night, occur predominantly in the ionosphere. This phenomenon commonly appears between 60 and 72 degrees north and south latitudes, which falls within the arctic and antarctic polar circles.
The likelihood of auroral appearances increases as you get closer to the north magnetic pole. Northern lights formed near the magnetic pole are precisely 90 degrees, but from far, they illuminate the northern horizon with a greenish glow, sometimes a pale red as if the Sun were rising from an unusual direction. Northern lights often occur on solstices.
Northern lights can be observed from all over the Earth and on other planets. The closer they are to the poles, the more visible they are due to the more extended darkness and magnetic field duration.
The Cree people called this exciting event the Dance of the Spirits. In the middle ages in Europe, it was believed that the northern lights were a sign from God.
Northern lights in the upper atmosphere (from 80 km above) gain electrons from ionized nitrogen atoms. The excited (high energy level) oxygen and nitrogen atoms return to the ground energy level, resulting in photon emission. They were ionized by the collision of solar wind particles and accelerating along Earth's magnetic field lines. The high energy level decreases due to the emission of a photon of light or its collision with another atom or molecule.
Green is the most common of all northern lights, followed by pink (mixture of light green and red), pure red, yellow (mixed of red and green), and pure blue.
