Forget pictures in textbooks of Saturn, Jupiter, and the Moon, and look through a telescope at the real thing. The Judson B. Coit Observatory at Boston University not only allows BU astronomy majors to expand their knowledge of the brightness of stars and the wavelengths of light, it also enables members of the public to discover this world beyond — a world otherwise diminished in the photographs inside old school books.

Public Open Nights at the Observatory are held Wednesday evenings and offer a place for couples to stargaze or for families to explore the night sky. During the fall and winter, Open Nights start at 7:30pm and during the spring and summer at 8:30pm. The program lasts about an hour and is held on the roof of the College of Arts and Sciences building.

Visitors are given telescopes and binoculars to observe the night sky. Of course, because weather is a factor, observations are canceled when there are clouds, haze, or rain. Call the information number to be sure the Open Night will be held. Don't forget, Boston is very cold in the winter so dress warmly when attending a winter program.

As well as a great view of the stars, you also can get a great view of Boston from the roof. The Observatory provides a unique location to survey a familiar city and sky from a new point of view.
