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.

Famous quotes containing the words scattered, light and/or sources:
“A country is strong which consists of wealthy families, every member of whom is interested in defending a common treasure; it is weak when composed of scattered individuals, to whom it matters little whether they obey seven or one, a Russian or a Corsican, so long as each keeps his own plot of land, blind in their wretched egotism, to the fact that the day is coming when this too will be torn from them.”
—Honoré De Balzac (1799–1850)
“They give birth astride of a grave, the light gleams an instant, then it’s night once more.”
—Samuel Beckett (1906–1989)
“On board ship there are many sources of joy of which the land knows nothing. You may flirt and dance at sixty; and if you are awkward in the turn of a valse, you may put it down to the motion of the ship. You need wear no gloves, and may drink your soda-and-brandy without being ashamed of it.”
—Anthony Trollope (1815–1882)
