All of our programming is free and open to the general public. Seating is on a first-come basis. We 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, or to contact the planetarium director, use the mail link in the menu bar on the righthand side of this page. You can also leave a phone message at 860-832-2950.

Upcoming Public Planetarium Shows

Our next regularly scheduled public show will be on Saturday, August 3rd. The topic for that show will be The Sun. Later in the month on Saturday, August 17th, the public show will be focused on different types of Stars. Doors to the planetarium will open at 7:30 PM, and the program begins at 8 PM. Plan on being here at least 15 minutes before the show starts because the show starts promptly at 8 PM and late admittance is not guaranteed. After the show, if skies are clear, we invite you to join us on the roof for observing of the real night sky through our telescopes.

Announcing Our New Planetarium Head!

We are excited to announce that after a detailed search process, Ms. Carol Ivers has been selected to lead the planetarium and observatory and is now on board! Watch this space for some exciting new changes over the next few months! To schedule a free show for your public group, please use the email link in the navigation bar. We prefer this to phone calls because email provides a written record of your request.
