What is sky?

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:

    The temples, the tank, the jail, the palace, the birds, the carrion, the Guest House, that came into view as they issued from the gap and saw Mau beneath: they didn’t want it, they said in their hundred voices, “No, not yet,” and the sky said, “No, not there.”
    —E.M. (Edward Morgan)

    What is saved in the cinema when it achieves art is a spontaneous continuity with all mankind. It is not an art of the princes or the bourgeoisie. It is popular and vagrant. In the sky of the cinema people learn what they might have been and discover what belongs to them apart from their single lives.
    John Berger (b. 1926)

    The sky it seems would pour down stinking pitch,
    But that the sea, mounting to the welkin’s cheek,
    Dashes the fire out.
    William Shakespeare (1564–1616)
