Are also known as Auroras or Aurora Borealis, which occur in high latitudes. Charged particles are emitted from the sun and are funneled into the upper atmosphere (known as the ionosphere) by the Earth’s magnetic field. The particles collide and their energy level changes. The color variation is the result of different elements being excited and returning to their ground state.
