Seen from the shores of Lake Superior, an August 4 aurora glows green topped with blueish-purple. Auroras glow in different colors based on the types of atoms in the atmosphere and how high they are in the sky.
Humans mostly see auroras in shades of yellowish-green. That's because the eye sees a light show created by oxygen atoms at lower altitudes, about 62 to 186 miles (100 to 300 kilometers) above the surface.
Blues and purples are created by lighter gases such as hydrogen and helium, while low-level nitrogen can add red fringes to the bottoms of green auroral curtains.
