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:

    The important question is not, what will yield to man a few scattered pleasures, but what will render his life happy on the whole amount.
    Joseph Addison (1672–1719)

    Are not the days of my life few? Let me alone, that I may find a little comfort before I go, never to return, to the land of gloom and deep darkness, the land of gloom and chaos, where light is like darkness.
    Bible: Hebrew, Job 10:20.

    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)
