Entry No. 64 — the Chicago file — filed under: after-dark
Cernan Earth and Space Center
A small, unflashy planetarium on the Triton College campus named for Apollo 17 commander Gene Cernan, the last person to walk on the moon. On Saturday evenings it runs back-to-back domed programs, including a 7pm sky show and an 8:30pm laser light show under the projection dome. Tickets are cheap, the crowds are local, and there's a free 'Star Store' gift shop attached.
The story
Most Chicagoland stargazers default to fighting for parking on Northerly Island to visit Adler. You, on the other hand, pull onto the suburban community college campus of Triton College in River Grove, past a real Nike Tomahawk missile and an Apollo test capsule sitting outside the building like casually parked sedans. The Cernan Earth and Space Center exists because Captain Eugene 'Gene' Cernan—commander of Apollo 17 and the last human to leave footprints on the lunar surface in December 1972—grew up right down the road in Bellwood and Maywood. When Triton dedicated the center in 1974 (and opened its current building in 1985), Cernan attended in person, helping establish a neighborhood space hub that traded downtown tourist hype for real astronomical gear.
Inside the lobby, before you even buy a show ticket, you're standing inches from authentic NASA artifacts: Cernan’s worn Apollo 10 spacesuit from his 1969 lunar dress rehearsal, an illuminated Lucite pyramid housing a genuine moon rock sample collected during Apollo 17, space navigation hardware, and local Illinois fossil collections. The venue's core is its 93-seat, 44-foot-diameter dome theater, equipped with a Konica-Minolta Super MediaGlobe II fulldome digital projector alongside a Voyager laser system.
While daytime hours are reserved for student groups and astronomy classes, Saturday nights are when the center opens to the neighborhood. The 7:00 PM slot presents standard astronomy programming—live tours of the night sky and fulldome science featurettes—followed at 8:30 PM by full-dome cosmic laser shows set to rock and pop soundtracks. You won't find slick corporate sponsorships or overpriced concessions here, just local families, space enthusiasts, and an attached Star Store gift shop selling inexpensive science gear.
What it's like
Expect a refreshingly low-key suburban experience with zero downtown friction—parking in the campus lots directly outside is free. Plan to arrive 15 to 20 minutes before showtime to examine Gene Cernan's Apollo 10 suit and the moon rock exhibit in the lobby without fighting crowds. Tickets are cheap and purchased at the door on a first-come, first-served basis for the 93-seat dome theater. If you catch both the 7:00 PM sky show and the 8:30 PM laser show, use the intermission to wander through the tiny Star Store gift shop.
The move: Catch the Saturday-evening sky show followed by the 8:30 laser light show, then browse the little Star Store.
