Airglow

"Night glow" redirects here. For the hot air balloon event, see Balloon glow. For luminance of the night sky caused by artificial light sources, see skyglow.

Airglow over the VLT platform[1]
The yellow line of the lowest airglow, at about one hundred kilometers at the edge of space and the lower edge of the thermosphere (invisible), which continues with green and red bands of airglow or aurorae over several hundred kilometers, and lies above the pink mesosphere, white and blue stratosphere, as well as orange troposphere afterglow and silhouettes of clouds at the bottom.

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.
