Beneath this dome on Northerly Island along the shore of Lake Michigan is the Adler Planetarium. It offers three theaters, countless science and space exhibitions plus the Doane Observatory whose enormous telescope allows the public to see planets and stars that are light years away. When the planetarium opened in 1930, it was named after Max Adler who was an executive at Sears Roebuck & Company before becoming a philanthropist and the project’s major benefactor.
