Looking at time lapses taken from the International Space Station, I discovered that the Earth's atmosphere can glow at night, even when it seems that those pictures were taken far away from auroras.
Here is the origin of airglow, according to this Wikipedia article:
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.
Now, my question is about whether or not airglow should be visible (with the naked eye) when looking at Earth's atmosphere from space at night. If not always visible or if the intensity of it varies a lot, is there a way to compute how intense it would be ?
