The Fascinating Aurora


Aurora is a light ray which occurs in the ionosphere layer of a planet. It is really famous for its striking colours and beautiful shapes. This phenomenon could happens because of the interaction between a planet's magnetic field and charged particles from the sun.

On earth, aurora could be seen in the north pole (known as Aurora Borealis) and in the south pole (known as Aurora Australis). Sometimes, aurora also appears at the peak of tropical mountains.
