Airglow (also called nightglow) is a faint emission of light by a planetary atmosphere. In the case of Earth's atmosphere, this optical phenomenon causes the night sky never to be completely dark, even after the effects of starlight and diffused sunlight from the far side are removed. This phenomenon originates with self-illuminated gases and has no relationship with Earth's magnetism or sunspot activity.

Green light is the brightest airglow. It comes from excited oxygen atoms located between 56 to 62 miles high. This band of green is readily observable from spacecraft looking back toward earth.
