Polar lights (aurora polaris) are a natural phenomenon found in both thenorthern and southern hemispheres that can be truly awe inspiring. ... These changes generate currents of charged particles, which then flow along lines of magnetic force into the Polar Regions.
The earth's magnetic field is a modified bar magnet. ... This results in an oval ring around each magnetic pole where auroras occur. The north pole aurora is called the aurora borealis and the aurora at the south pole is called the aurora australis.

When charged particles from the sun strike atoms in Earth's atmosphere, they cause electrons inthe atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates thebeautiful aurora, or northern lights.
