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:
“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)
“When the sky is clear, carry an umbrella; though your stomach is full, carry provisions.”
—Chinese proverb.
“Seas of bright juice suffuse heaven.
The earth by the sky staid with, the daily close of their junction,
The heav’d challenge from the east that moment over my head,
The mocking taunt, See then whether you shall be master!”
—Walt Whitman (1819–1892)
