No need to buy a ticket to the Adler Planetarium for a few days this November.
The planetarium will offer free general admission for Illinois residents on Nov. 10 and Nov. 15-17 with proof of residency.
The museum will run normal hours from 9:30 a.m. to 4 p.m. on all four days.
Illinois residents will also have access to discounted prices on all-access passes, which include admission to the museum's sky shows.
Non-Illinois residents will still be charged the normal $15 for general admission.
