Explanation of Northern lights.

When charged particles from the sun strike atoms and molecules in the Earth's atmosphere, they excite those atoms, causing them to light up. When charged particles from the sun strike atoms in Earth’s atmosphere, electrons move to higher energy orbits, further away from the nucleus. Then when an electron moves back to a lower energy orbit, it releases a particle of light. Science says that different gasses in the earth's atmosphere give off different colors when they are excited. Oxygen gives off the green colors, and nitrogen gives off the red and blue colors. http://sciblogs.co.nz/app/uploads/2010/08/aurora.jpg
