Bridgewater State University Observatory The Bridgewater State University Observatory is on top of the BSU Science and Mathematics Center—we do outreach, research, and astrophotography!

The BSU Observatory has an extremely active outreach program, and can run up to about a dozen telescopes at once. During public nights, we use a combination of telescopes on our patio decks, mostly with 8-inch apertures, to view planets, stars, galaxies and nebulae. The dome houses a Celestron C-14 Schmidt-Cassegrain telescope used primarily for student research. Call the observatory hotline (508-531-3275), check this page, or follow us on Twitter to find out whether the weather will allow an event to occur. You may also call the hotline or check our website (www.bridgew.edu/observatory) to find out opening times. Admission is always free. If you are interested in scheduling a private viewing event for a group of 25 ore more people, please call the observatory office at 508-531-2093. We also run hands-on workshops geared toward K-12 students intended to occur immediately before a viewing event.
