A planetarium (plural planetariums or planetaria) is a theatre built primarily for presenting educational and entertaining shows about astronomy and the night sky, or for training in celestial navigation. A dominant feature of most planetariums is the large dome-shaped projection screen onto which scenes of stars, planets and other celestial objects can be made to appear and move realistically to simulate the complex 'motions of the heavens'. The celestial scenes can be created using a wide variety of technologies, for example precision-engineered 'star balls' that combine optical and electro-mechanical technology, slide projector, video and fulldome projector systems, and lasers. Whatever technologies are used, the objective is normally to link them together to provide an accurate relative motion of the sky. Typical systems can be set to display the sky at any point in time, past or present, and often to show the night sky as it would appear from any point of latitude on Earth.

Famous quotes containing the word planetarium:

    In a large university, there are as many deans and executive heads as there are schools and departments. Their relations to one another are intricate and periodic; in fact, “galaxy” is too loose a term: it is a planetarium of deans with the President of the University as a central sun. One can see eclipses, inner systems, and oppositions.
    Jacques Barzun (b. 1907)
