Sky

The sky, also known as the celestial dome, commonly refers to everything that lies a certain distance above the surface of Earth, including the atmosphere and the rest of outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling. The celestial sphere is divided into regions called constellations. Usually, the term sky is used from the point of view of the Earth's surface. However, the exact meaning of the term can vary; in some cases, the sky is defined as only the denser portions of the atmosphere, for example.

Famous quotes containing the word sky:

    With spring the father-sky remakes the world:
    The male shower has flowed into the bride,
    Earth’s body; then shifted through sky and sea and land
    To touch the quickening child in her deep side.
    Allen Tate (1899–1979)

    Usually the scenery about them is drear and savage enough; and the logger’s camp is as completely in the woods as a fungus at the foot of a pine in a swamp; no outlook but to the sky overhead; no more clearing than is made by cutting down the trees of which it is built, and those which are necessary for fuel.
    Henry David Thoreau (1817–1862)

    Suspended lion face
    Spilling at the centre
    Of an unfurnished sky ...
    Philip Larkin (1922–1986)
