Maria Mitchell Association Open Telescope Night

Open Nights are offered on Mondays and Wednesdays from 9pm-10:30pm, June 14-August 30.

Due to COVID-19 safety protocols, Open Nights in 2021 will have limited capacity and different viewing abilities. Masks are required.

Join our professional astronomers for an impressive tour of Nantucket’s night sky. Our staff will assist you and answer questions while you view the wonders of the night sky through up to three different telescopes, including our historic 8-inch Alvan Clark refractor and our modern 24-inch research telescope. Get a chance to view the Moon, planets, bright stars, nebulae, and even other galaxies! Learn about the cutting-edge research being conducted by Maria Mitchell Observatory astronomers and interns. The presentation will end with a constellation tour outside on the observatory deck. 

Programs take place at 59 Milk Street Extension and are weather permitting.
