All of our programming is free and open to the general public. Seating is on a first-come basis. Our regularly scheduled planetarium shows occur at 8 PM on the first and third Saturdays of each month, except when they fall on Christmas Eve, Christmas Day, or New Years Eve or Day. Directly after each show, if the skies are clear, the public is invited up to the roof to view the night sky through a variety of telescopes and other instruments. 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.

Are You Ready for the August 21, 2017 Solar Eclipse?

Dubbed "The Great American Eclipse," this amazing celestial event will be visible from Connecticut as a partial, not total, eclipse. This means that you need proper preparation to view it safely. CCSU astronomy professor Dr. Kristine Larsen is available to speak on this important topic at libraries, schools, and other public venues within 20 miles of CCSU between now and August 15, free of charge, schedule permitting. Please send email to the link on the navigation bar with the subject line "SOLAR ECLIPSE TALK." The venue needs to provide a projection screen and a projector that can be hooked up to a laptop (or equivalent facilities).

Eclipse Resources:
