The planetarium is room 211, located on the main (second floor) of Nicolaus Copernicus Hall on the east side of campus (closest to Route 9).

All of our events are free, open to the public, and include free parking on surface lots near Copernicus Hall and in the Vance Parking Garage.

We book planetarium shows, observing sessions, lectures, and hands-on activities for organizations and school groups at your request absolutely free! However, we do not book birthday parties or other non-astronomical events. Please allow AT LEAST 2 weeks lead time for scheduling. All scheduling blocks are on a first-come basis and prime slots sometimes fill up months in advance.

    Planetarium Shows and Events:


    On Saturday October 3 and 17 at 8 PM, we will have our regularly scheduled free show in our planetarium. This month's show is "Planets of the Sun."

    For planetarium shows, seating is first come, first served. The planetarium is located in Copernicus Hall (Building 23 on the campus map). Convenient parking is in the Copernicus (South) garage (building 17).


    Observatory Events:

    On Saturday  October 3 and 17 join us for a free observing session directly afterward the planetarium show (observing is weather permitting: we need a clear sky).


    The observatory is located on the roof of Copernicus Hall. Take the elevators to the 5th or 6th floor and follow the signs.
