The Physics, Astronomy and Geosciences Department offers planetarium shows on the third Friday of every month throughout the academic year. These shows are open to the public and usually include a tour of the night sky and discussion of topics in astronomy.

The Planetarium is Towson University’s primary tool for public outreach in astronomy. Located in the Science Complex, Room 2206, our Planetarium allows us to simulate the Universe at any time of the day or night, regardless of weather.  It has seating for 50 people under its 24-foot (7.3 meter) diameter dome.

Our all-new Planetarium was built by Spitz, Inc. in 2021.  The SciDome presentation system projects simulations from StarryNight, The Layered Earth, Zygote Body, and full dome video through two 4K Canon projectors.  The state-of-the-art NanoSeam dome ensures an immersive 4K-by-4K ultra-high-definition image.  The quadraphonic sound system allows for an extra dimension of experience as you tour the cosmos.

Public Shows

Public shows are held the evening of the third Friday of every month, and last approximately 30 to 45 minutes in length.  Seating is on a first-come, first-served basis except for the designated ADA/wheelchair seating.  Extra showings are added to accommodate overflow audiences.

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.

Private Shows

Private showings can be arranged for schools, events, and other organizations. We ask that groups range in number from 15 to 50 persons. We regret that we cannot accommodate small groups on demand. Please use our Planetarium Request Form to inquire about a private showing for your organization.
