Aurora is a phenomenon that the light burning in a layer of the ionosphere of a planet. This light is created by the interaction between the planet's magnetic field with particles emitted by the sun. On Earth, auroras occur in the area around the north pole and south pole. Aurora is happening in the northern region known as the Aurora Borealis, while occurring in the south known as the Aurora Australis. But sometimes the aurora also appears on top of a mountain in the tropics.
