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:
“Awake! the land is scattered with light, and see,
Uncanopied sleep is flying from field and tree:”
—Robert Bridges (1844–1930)
“Why is light given to one in misery, and life to the bitter in soul, who long for death, but it does not come, and dig for it more than for hidden treasures; who rejoice exceedingly, and are glad when they find the grave?”
—Bible: Hebrew, Job 3:20-22.
“Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
