The Adler Planetarium located in Chicago, Illinois, was opened in 1930 as the first planetarium in the United States. It is named after founder Max Adler to enable all citizens the chance to observe the sky like astronomers. It was also featured at the Chicago exposition and is considered a National Historic Landmark. Today, the planetarium receives more than half a million visitors annually and features many outreach programs designed to get citizens, and especially kids, into science.
