Scattered Light From Extraterrestrial Sources
Not only sunlight is scattered by the molecules in the air. Starlight and the diffuse light of the milky way are also scattered by the air, and it is found that stars up to V magnitude 16 contribute to the diffuse scattered starlight.
Other sources such as galaxies and nebulae don't contribute significantly.
