Sky Brightness - Scattered Light From Extraterrestrial Sources

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:

    Thou blind man’s mark, thou fool’s self-chosen snare,
    Fond Fancy’s scum and dregs of scattered thought,
    Band of all evils, cradle of causeless care,
    Thou web of will whose end is never wrought;
    Desire! desire, I have too dearly bought
    With price of mangled mind thy worthless ware;
    Sir Philip Sidney (1554–1586)

    ... by desiring what is perfectly good, even when we don’t quite know what it is and cannot do what we would, we are part of the divine power against evil—widening the skirts of light and making the struggle with darkness narrower.
    George Eliot [Mary Ann (or Marian)

    The sources of poetry are in the spirit seeking completeness.
    Muriel Rukeyser (1913–1980)
