All of our programming is free and open to the general public. Seating is on a first-come basis. We also offer free planetarium shows, observing sessions, and hands-on astronomy workshops to school and community groups and civic organizations. We do not schedule shows or observing sessions for individual families. To book a special group event, use the mail link in the menu bar on the righthand side of this page.

Upcoming Public Planetarium Shows

On Saturday October 6 and 20, we will have our next regularly scheduled free show in our planetarium. Our show will be "Inventions that Changed the World". Join us as we explore inventions that have revolutionized our lives. As always, a tour through the current night sky will be included.

The shows begin at 8:00 PM in our planetarium but come a bit earlier if you want to participate in some of our physics fun demonstrations that start at 7:30 PM. 


Bidding a Fond Farewell to Craig Robinson

After more than 3 decades of sharing the night sky with the general public at the Copernican Planetarium (and prior to that at other planetariums), Craig Robinson is retiring. Craig's last public show will be September 15 so please be sure to wish him a happy, healthy, and long retirement!

Craig's shoes (or should we say sweater?) will be very difficult to fill! Until a new head for the planetarium is hired, other staff will be filling in as they can. Be sure to check this website regularly for updated information as our show schedule may change during this transition.

Special Events:

Keep checking this site for information on CCSU's participation in International Dark Matter Day (a special event at CCSU is tentatively scheduled for October 30).

Students in the Observational Astronomy class will be hosting their annual several nights of free public observing at the end of the semester. More information will be available around Thanksgiving.

It's not too early to prepare for the April 8, 2024 Total Solar Eclipse!

Plan ahead for the April 8, 2024 total solar eclipse (totality will be visible from parts of New England!)

What's it like to experience a total solar eclipse? Listen to Dr. Larsen's enthusiastic comments in this video taken during the total solar eclipse in the Faroe Islands (her 4th total solar eclipse).
