The particular sky (or perhaps celestial dome) can be anything that is above the top of the Earth, such as the natural environment in addition to outer space or room.With astronomy, the heavens is usually called the heavenly ballpark. This is actually seen from Earth's surface as an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling. The celestial sphere is conventionally divided into regions called constellations. Commonly, the phrase air is utilized informally as being the point of view from the Earth's surface; however, the meaning and usage can vary. In some cases, such as in discussing the weather, the sky refers to only the lower, more dense portions of the atmosphere.During daylight, the sky appears to be blue because air scatters blue sunlight more than it scatters red. At night, the sky appears to be a mostly dark surface or region scattered with stars. During the day, the Sun can be seen in the sky unless obscured by clouds. In the night sky (and a certain degree during the day) the moon, planets and stars are visible in the sky.
Some of the natural phenomena seen in the sky are clouds, rainbows, as well as aurorae. Fast along with rain can be affecting the sky during storms. Birds, insects, aircraft, and kites are generally usually viewed as to help travel in the sky.
Due to human activities, smog during the day and light pollution throughout the night tend to be observed above massive places.
