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:

    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”)

    So fallen! so lost! the light withdrawn
    Which once he wore!
    The glory from his gray hairs gone
    Forevermore!
    John Greenleaf Whittier (1807–1892)

    The American grips himself, at the very sources of his consciousness, in a grip of care: and then, to so much of the rest of life, is indifferent. Whereas, the European hasn’t got so much care in him, so he cares much more for life and living.
    —D.H. (David Herbert)
