Dearborn Observatory at Northwestern University
Hours: 9-11 p.m. April 1-Sept. 30; 8-10 p.m. Oct 1-March 31
Historical telescope still in operation. Young eyes can roam the skies here every Friday night. Gaze through an 18.5-inch telescope, see planets and star formations, ask questions and get answers. Great for kids to spark an interest in science. Please note that the building does not have an elevator and the dome is not heated.
