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:

    “Across the lonely beach we flit,
    One little sandpiper and I;
    And fast I gather, bit by bit,
    The scattered driftwood, bleached and dry.
    The wild waves reach their hands for it,
    The wild wind raves, the tide runs high,
    As up and down the beach we flit—
    One little sandpiper and I.”
    —Celia Thaxter (”Laighton”)

    “Decade after decade, artists came to paint the light of Provincetown, and comparisons were made to the lagoons of Venice and the marshes of Holland, but then the summer ended and most of the painters left, and the long dingy undergarment of the gray New England winter, gray as the spirit of my mood, came down to visit.”
    —Norman Mailer (b. 1923)

    “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)
