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 stars are scattered all over the sky like shimmering tears, there must be great pain in the eye from which they trickled.

    When the sky is clear, carry an umbrella; though your stomach is full, carry provisions.
    Chinese proverb.

    And there is nothing in the eye,
    Shut shutter of the mineral man
    Who takes the fatherless dark to bed,
    The acid sky to the brain-pan;
    And calls the crows to peck his head.
    Allen Tate (1899–1979)
