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:
“Beyond the sky there is more sky; beyond one person there are others as well.”
—Chinese proverb.
“After all anybody is as their land and air is. Anybody is as the sky is low or high. Anybody is as there is wind or no wind there. That is what makes a people, makes their kind of looks, their kind of thinking, their subtlety and their stupidity, and their eating and their drinking and their language.”
—Gertrude Stein (1874–1946)
