Solar winds

Explanation:

Auroras are beautiful colorful lights in the sky. This phenomenon occurs when charged particles (Solar Winds) from the Sun interacts with the magnetic field of the Earth. Photons are released when the electrons in the atoms of the atmosphere drop from high energy state to low energy state. The color depends upon the type of gas present. It usually occurs near the poles as the strength of the magnetic field is strongest near them. Northern light or Aurora Borealis occurs around north pole and southern lights or Aurora Australis around south pole.
