The northern lights is a natural occurring phenomenon that lights up the sky in northern region. The "aurora borealis" most often occurs around the equinoxes, and a similar spectacle happens in the southern hemisphere, known as the aurora australis. Auroras occur when increased solar activity sends charged particles toward Earth.

Auroras are created when the charged particles flow along Earth's magnetic field lines. The particles hit the atmosphere at the Poles and excite air molecules, which release the extra energy as light.
