Located on Lake Michigan, the Adler is America's first planetarium and is the only museum in the world with two full-size planetarium theaters. The night sky has been visible from the historic Sky Theatre since 1930, while the all-digital StarRider Theatre is the first of its kind in the world and affords a virtual outer space experience in its 55-foot (17m) wide and three story high area. The Adler is also home to numerous exhibits including antique astronomical instruments dating back to 12th-century Persia and interactive displays.
