Planetarium Shows
Embrace your inner astronomer! Be inspired. Explore the far reaches of the universe. Discover the wonders beyond Earth’s atmosphere in the only public planetarium in central Massachusetts. Our full-dome movie offerings rotate bi-monthly! Check back next month for our next set of planetarium offerings.
You can also join us for a monthly Speaker Series in the Alden Planetarium and dive into the latest discoveries in the grandest science of all. Every month, a researcher from the Worcester area will come to the EcoTarium to discuss their work — everything from Martian water to astrophotography and from community science to space telescopes!
