Alden Digital Planetarium

Immerse yourself in outer space

Discover the fascinating world of astronomy – from the closest star to the furthest reaches of the universe. Experience cutting edge scientific visualization and imaginative animation as well as a fully navigable model of the solar system and the galaxy.

The Alden Digital Planetarium was the first digital planetarium in Massachusetts! Featuring Digital Light Processing technology from Sky-Skan, Inc., the EcoTarium's planetarium uses images from NASA and the Hubble Space Telescope to create a three-dimensional solar system projected onto a 40-foot dome. With immersive surround sound technology from Bose, the planetarium offers a 360-degree, multi-sensory experience.


Tickets can be purchased at the Information Desk on the day of your visit.
