The sky (also sometimes called celestial dome) is everything that lies above the surface of the Earth, including the atmosphere and outer space.
In the field of astronomy, the sky is also called the celestial sphere. This is an abstract sphere (concentric to the Earth) on which the Sun, Moon, planets, and stars appear to be drifting. The celestial sphere is conventionally divided into designated areas called constellations.
The daytime sky usually appears blue because air molecules scatter shorter wavelengths of sunlight more than longer ones (redder light). The night sky appears to be a mostly dark surface or region with stars.
Some of the common natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning and precipitation are also often visible in the sky.
Some might be wondering: what is a black hole? A black hole is certainly a region of spacetime where gravity is so strong that nothing (no particles or even electromagnetic radiation such as light) can really escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a certain black hole.
