Stargazing Fridays

See the Moon, planets, and stars through our historic—and now computer controlled—Alvan Clark & Sons 8" refracting telescope.

The Observatory is open to the public every Friday from 7:00 to 10:30 PM, weather permitting. Friday admission to the Observatory is free (does not include access to the Museum).

Phone 410-545-2999 after 5:00 PM on Fridays to find out if the Observatory will be open that night.

The Observatory is on the roof of the Maryland Science Center. On Fridays, enter through the Harborside Entrance on the northern side of the building facing the Inner Harbor. (The Group Entrance, on the southern side, is for Camp-In only.)

The Observatory is open to the outdoors, so please dress appropriately. If a large group (20-plus people) plans to visit, please notify us at least a week ahead of time.
