Alden Planetarium

We want every child in our community to know they can reach for the stars! Support us to make our planetarium upgrades possible Donate Now. The EcoTarium is home to the only planetarium in central Massachusetts. The new digital planetarium will inspire all who experience it and will help contribute to our ability to teach astronomy and other science, technology, engineering, and math (STEM) content interactively. The optimized space and new laser projectors will allow us to offer dynamic new shows and programs, share updated content and scientific discoveries, and create new special events focused on celestial events. Improving the planetarium’s capabilities and physical space will directly correlate with the quality education we can provide to the community and especially to Worcester Public School students. We are proud to say this new space will truly be for everyone in our community.
