Adler Planetarium: Free Day

The Adler Planetarium is free for Illinois residents (with proof of residency) every Wednesday evening from 4:00 pm–10:00 pm. Stop by after work or school, or for date night and enjoy everything the Adler has to offer at night, for free as part of our Illinois Resident Discount Days program.
Reserve your free Museum Entry tickets and add on any sky shows for the full experience! Illinois residents may upgrade to a Museum Entry +2 pass at a discounted price and gain access to any of our breathtaking sky shows. You’ll be given an option to do this upon checkout. All tickets must be purchased online and in advance. All sales are final. Proof of residency will be required upon checkout. To show proof of residency, you can use a valid Illinois driver’s license or photo ID, Illinois student ID with photo, or a photo ID plus a document (utility bill, lease, etc.) that shows your name and Illinois address.
