===Airglow of the Earth===

The Earth's night sky is illuminated by diffuse light, called [[airglow]], that is produced by radiative transitions of atoms and molecules.<ref>{{cite journal | vauthors = Silverman SM | title = Night airglow phenomenology. | journal = Space Science Reviews | date = October 1970 | volume = 11 | issue = 2 | pages = 341–79 | doi = 10.1007/BF00241526

</ref> Among the most intense such features observed in the Earth's night sky is a group of infrared transitions at wavelengths between 700&nbsp;nanometers and 900&nbsp;nanometers. In 1950, [[Aden Meinel]] showed that these were transitions of the hydroxyl molecule, OH.<ref>{{cite journal
