Watson-King Planetarium

On the third Friday of every month throughout the year, faculty, students and friends of the TU Physics, Astronomy, and Geosciences Department give presentations at the planetarium. Shows start at 8 p.m. and are open to the public. They usually include a tour of the night sky and discussion of topics in astronomy.

The Watson-King Planetarium, located in The Science Complex, Room 2206, is Towson University’s primary tool for public outreach in astronomy.

Established in 1965, the Watson-King Planetarium allows us to view the stars at any time of the day or night, in any weather. It has seating for 44 people under its 22’ diameter dome. The stars and planets are displayed by a Digital Starlab projector, and can show views from any point in space at any time. Our new quadraphonic sound system allows for an extra dimension of experience as you tour the cosmos.

When weather permits, the planetarium shows are followed by telescope observing using our new 16” diameter Ritchey-Chretien reflecting telescope as well as with some of our portable 8” Celestron telescopes.
