Sky

The sky (or 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 viewed 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. Usually, the term sky is used informally as 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 to some extent 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, and aurorae. Lightning and precipitation can also be seen in the sky during storms. Birds, insects, aircraft, and kites are often considered to fly in the sky. Due to human activities, smog during the day and light pollution during the night are often seen above large cities.

Places in The Hitchhiker's Guide to the Galaxy

This is a list of places featured in Douglas Adams's science fiction series, The Hitchhiker's Guide to the Galaxy. The series is set in a fictionalised version of the Milky Way galaxy and thus, while most locations are pure invention, many are based on "real world" settings such as Alpha Centauri, Barnard's Star and various versions of the Earth.

The Galaxy

"The Galaxy" is our home galaxy, the Milky Way, though it is referred to exclusively as "the Galaxy" in the series. Apart from a very brief moment during the first radio series, when the main characters were transported outside the galactic plane into a battle with Haggunenons, and a moment when one of Arthur's careless remarks is sent inadvertently through a wormhole into "a distant galaxy", the Galaxy provides the setting for the entire series. It is home to thousands of sentient races, some of whom have achieved interstellar capability, creating a vast network of trade, military and political links. To the technologically advanced inhabitants of the Galaxy, a small, insignificant world such as Earth is considered invariably primitive and backward. The Galaxy appears, at least nominally, to be a single state, with a unified government "run" by an appointed President. Its immensely powerful and monumentally callous civil service is run out of the Megabrantis Cluster, mainly by the Vogons.

Sky blue

Sky blue is the name of a color that resembles the color of the sky at noon. The entry for "sky-blue" in Murray's New English Dictionary (1919) reports a first sighting of the term in the article on "silver" in Ephraim Chambers's Cyclopaedia of 1728. However, many writers had used the term "sky blue" to name a color before Chambers. For example, we find "sky blue" in A Collection of Voyages and Travels (London: Awnsham and John Churchill, 1704), vol. 2, p. 322, where John Nieuhoff describes certain flowers: "they are of a lovely sky blue colour, and yellow in the middle". The sense of this color may have been first used in 1585 in a book by Nicolas De Nicolay where he stated "the tulbant of the merchant must be skie coloured".

Variations of sky blue

Celeste

Celeste (pronounced che-les-te in Italian se-lest in English) is the colloquial name for the pale turquoise blue colour associated with Italian bicycle manufacturer Bianchi S.p.A and sometimes known as Bianchi Green. In Italian, as the name indicates (Celestial), it is an attempt to reproduce the colour of clear skies. In English, this colour may also be referred to as Italian sky blue.
