A planetarium is a theater built especially for presenting views of the skies. A specially designed digital projector sends images onto the domed ceiling.  The planetarium computer can replicate views of the night sky from just about any location on Earth. Explore the constellations, the solar system, and the cosmos in the Observatory's planetarium.  The planetarium seats 28 people.
