Adler Planetarium sits at the far tip of Chicago's Museum Campus, pairing immersive sky shows and historic space exploration exhibits with sweeping skyline views. The museum is also home to the Doane Observatory, which holds the largest public telescope in the Chicago area, plus interactive spaces like Planet Explorers that give young children room to climb and play.
Chicago CityPASS® tickets include Adler Planetarium as a choice attraction, with museum entry plus your choice of two sky shows. Here are the experiences worth prioritizing, how long to stay, and what else is nearby.
Exploring the Wonders of the Adler Planetarium in Chicago
Adler Planetarium is the first planetarium in the Western Hemisphere, a distinction it has held since opening on Chicago's lakefront in 1930. Founder Max Adler, a Chicago business leader, wanted a public place where anyone could learn about the universe.
The centerpiece is the Grainger Sky Theater, set beneath the original copper-clad dome of the Art Deco building. This was the country's first planetarium theater, and today it uses ultra-high-resolution projection to surround you with stars, planets, and distant galaxies.
Adler also plays an active role in public space science. Its researchers lead people-powered projects that invite volunteers to help study real data, and astronomers share their work with guests in the Space Visualization Lab.
Immersive Sky Shows and Award-Winning Theaters
Chicago CityPASS® tickets include two sky shows with your museum entry at Adler Planetarium. You choose both Dome Shows, so you can pair a live, narrated program with a fully produced film. Reserve your first show when you book museum entry and choose your second after you arrive, since shows can sell out later in the day.
Adler's two dome theaters each offer a different feel:
- Grainger Sky Theater: A 70-foot dome curves 190 degrees down toward the floor, so the imagery wraps around you from nearly every angle.
- Space Theater: Opened in 1999 as the nation's first full-dome planetarium, this 55-foot dome tilts over stadium-style seating. Its high-contrast projection makes stars look especially crisp during Skywatch Live, a guided tour of Chicago's night sky without the light pollution.
Most shows run about 30 minutes, and the lineup changes throughout the year. Families with preschoolers should look for One World, One Sky, which takes Elmo and Big Bird to the Moon and back. The shows turn big astronomy concepts into something you can see and feel.
Must-See Space Exploration Exhibits and Historic Artifacts
The standout Adler Planetarium exhibits mix rare artifacts with hands-on displays.
Mission Moon follows the late Captain James A. Lovell Jr., commander of Apollo 13, through his personal journey into space. Its headline artifact is the Gemini 12 spacecraft, which Lovell flew with Buzz Aldrin in 1966. You can even get close enough to peek inside. The gallery also displays a real Moon rock and interactive stations that put you in the middle of the Apollo 13 rescue.
Other Worlds, Adler's newest exhibition, explores gas giants, ice giants, super Earths, and mini-Neptunes. Highlights include a climbable ringed exoplanet model and the second-largest fragment of the Canyon Diablo meteorite.
Astronomy history comes into focus at Telescopes: Through the Looking Glass, a historic telescope exhibit spanning four centuries of instruments and featuring Chicago's legendary Dearborn refractor.
That story continues outdoors at the Doane Observatory. Its 24-inch reflector telescope, installed in 2020, is the largest publicly available telescope in the Chicago area and gathers more than 7,000 times the light of the unaided eye. Trained volunteers run public observing sessions on select evenings, weather permitting, so confirm the observing status a day or two ahead.
Hands-On Learning for Families and Young Explorers
Adler Planetarium is a good fit for toddlers and preschoolers, thanks to play areas designed for small visitors. Planet Explorers is the main draw for kids ages 3 to 8, who can climb inside a two-story rocket, work the controls, and tackle missions on an imaginary planet.
For the youngest guests, PlayLab in the Community Design Labs offers a block-building zone for children 6 and under, though it opens only on select days. Older kids can head to Star Studio to create space-inspired artwork.
Stroller parking, lockers, and restrooms with changing tables make the day easier. Consider booking a morning sky show while little ones are fresh, then saving Planet Explorers for when they need to burn off energy.
Practical Tips for a Stellar Museum Campus Visit
Plan to spend about three hours at Adler Planetarium to see the major exhibits and two sky shows at a comfortable pace. If you're short on time, focus on one Dome Show and Mission Moon.
Arriving close to opening gives you calmer galleries and the widest choice of show times. Illinois residents receive free admission on Wednesday evenings, which tends to bring bigger crowds. Those evenings are also your best chance to look through the Doane telescope, and seeing Adler Planetarium at night gives the museum a different mood as the city lights up across the water. Reservations are required for Chicago CityPASS® ticket holders, so book your entry time once your plans are set.
Adler sits on the northeastern tip of Northerly Island, a short walk from Shedd Aquarium and the Field Museum. Solidarity Drive, the road leading to the planetarium, offers one of the best panoramic views of the Chicago skyline.
