Quote:
Auroras are produced when charged particles from the sun strike atoms in Earth's atmosphere, and the colors depend on which types of atoms get hit. Oxygen usually generates green lights, but lower energy oxygen collisions or nitrogen atoms can create red glows. --National Geographic

Cool perspective, isn't it, with the red light dancing on top of the green.
