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 September 1 and 15, we will have our next regularly scheduled free show in our planetarium.

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.  September’s planetarium programs are based on an audience participation program trying to find the missing fortune of an amateur astronomer who has left his estate to his two sons but they can’t find the missing inheritance.  There are clues to the missing fortune scattered about the house for the audience to find and many of them are astronomical in nature.  It is the first time we have ever done a program quite like this one and if you like to solve mysteries this may be the planetarium program for you.   These programs are not intended for children under 10 years old.  After our the planetarium programs if the sky is clear we will observe the real night sky with our rooftop telescope and look at some of the planets that are out in the night sky in September.

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 the evening of October 30).

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).
