Upcoming Public Planetarium Shows

On Saturday December 15, we will have our next regularly scheduled free show in our planetarium. This month's shows feature the fifth installment/chapter of "Inventions That Changed the World." The show will explore inventions which have influenced communications on a global scale from the Gutenberg printing press to the internet and world wide web.

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 34 years of sharing the night sky with the general public at the Copernican Planetarium (and prior to that at other planetariums), Craig Robinson has retired. Craig's last public show was September 15, and we all 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.

Your generous support helps us keep our programming free for all members of the public as well as school and community groups:

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).
