Glossary term: Planetarium
Description: A planetarium is a theatre with specialized equipment that can be used for visualizing astronomical phenomena. Most planetaria consist of specialized projection equipment and a hemispherical dome. When stars and planets are projected onto the dome, the audience is sitting under an artificial night sky. Traditional, opto-mechanical, projectors are built specifically for simulating the night sky. Digital planetariums instead use one or more "specialized beamers", which can project not only the night sky, but any kind of moving image. This allows for "full dome movies" not only on astronomy, but on other topics – the audience can travel in a virtual spaceship, but also explore the micro-world of human DNA, for example.See this term in other languages
