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 Copernicus 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.

    Interested in viewing the total lunar eclipse on October 8? Get outside before dawn and look to the West. The moon enters the main part of earth's shadow (umbra) about 5:15 AM and the eclipse is total at 6:24 AM, but the moon unfortunately sets at 7:00 AM. Because we do not have a good Western horizon here we are not hosting viewing. You only need your eyes to see the eclipse, but binoculars are always a treat.


    SAVE THE DATE! On Saturday, October 18 we will be hosting Earth Science Day at CCSU. Join us in Copernicus Hall from 1:00 PM onward for fun, hands-on science activities for the entire family!



    Planetarium Shows and Events:

    On Saturday October 4 and 18 at 8 PM, we will have our regularly scheduled free show in our planetarium. Our shows in October will be on the 4th and 18th.

    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 4 and 18 join us for a free observing session directly afterward the planetarium show (observing is weather permitting: we need a clear sky). Our events in October will be on the 4th and 18th.

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