The sky’s not the limit at the Cleveland Museum of Natural History, where a new planetarium takes visitors deep into outer space. The Nathan and Fannye Shafran Planetarium promises to be one of the world’s great stargazing facilities, with a special projector that displays more than 5,000 celestial bodies on a 40-foot-wide dome. It also reproduces the motions and appearances of Mercury, Jupiter, Venus, Mars, and Saturn. In other words, the place is really far out. (800) 317-9155,
