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:

    ... anybody is as their land and air is. Anybody is as the sky is low or high, the air heavy or clear and anybody is as there is wind or no wind there. It is that which makes them and the arts they make and the work they do and the way they eat and the way they drink and the way they learn and everything.
    Gertrude Stein (1874–1946)

    Two wooden tubs of blue hydrangeas stand at the foot of the stone steps.
    The sky is a blue gum streaked with rose. The trees are black.
    The grackles crack their throats of bone in the smooth air.
    Moisture and heat have swollen the garden into a slum of bloom.
    Pardie! Summer is like a fat beast, sleepy in mildew....
    Wallace Stevens (1879–1955)

    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)
