Planetariums/Observatories

Taxonomy Code: TA-5500.7500

Observatories that maintain telescopes and other instrumentation for astronomical study and often conduct public tours which feature information about the facility's ongoing work as well as educational displays and exhibits of astronomical phenomena. Most observatories also maintain planetariums which have public auditoriums with large domed ceilings on which images of the sun, moon, planets, stars and other celestial bodies are projected by a complex optical instrument that can revolve to show principle celestial motions.
