Halos are formed when light refracts in ice crystals in cirrus clouds.
Rainbows form when light is refracted (or bent) through raindrops. The interior of the rainbow is bright, whereas the outside of the main rainbow is dark.
Auroras occur when highly charged particles from the sun interact with the air molecules at the top of our atmosphere.
