The Adler Planetarium is a public museum dedicated to the study of astronomy and astrophysics. It was founded in 1930 by Chicago business leader Max Adler. It is located on the northeast tip of Northerly Island at the shore of Lake Michigan in Chicago, Illinois. The Adler was the first planetarium in the United States and is part of Chicago's Museum Campus, which includes the John G. Shedd Aquarium and The Field Museum. The Adler's mission is to inspire exploration and understanding of the universe.

The Adler Planetarium opened to the public on May 12, 1930. For its design, architect Ernest A. Grunsfeld Jr. was awarded the gold medal of the Chicago chapter of the American Institute of Architects in 1931. It was declared a National Historic Landmark in 1987.

The Adler is home to three full size theaters, extensive space science exhibitions, the Gemini 12 space capsule, and a significant collection of antique scientific instruments and print materials. In addition, the Adler boasts the Doane Observatory, one of the only research-active, public urban observatories.

Outdoor sculptures at the planetarium include Man Enters the Cosmos by Henry Moore (1980), Spiral Galaxy by John David Mooney (1998), and America's Courtyard by Ary Perez and Denise Milan.

In 1913, Oskar von Miller of the Deutsches Museum commissioned the Carl Zeiss Works to design a mechanism that projects an image of celestial bodies onto a dome. This was achieved by Walther Bauersfeld and the invention became known as a planetarium when it debuted in 1923. Its popularity quickly spread, and by 1929, there were fifteen in Germany, two in Italy, one in Russia, and one in Austria. Max Adler, a former executive with Sears, Roebuck & Co. in Chicago, Illinois, had recently retired to focus on philanthropic endeavors, primarily on behalf of the local musical and Jewish communities. However, after listening to a friend describe a Munich planetarium, Adler decided that a planetarium would fit in well within the emerging Museum Campus in Chicago. Adler visited the Munich planetarium with his cousin, architect Ernest Grunsfeld Jr., whom Adler would commission to design the Chicago structure. He also learned about a sale of astronomical instruments and antiques by W. M. Mensing in Amsterdam, which he purchased the following year. The Mensing Collection became the focus of the Astronomical Museum. Adler offered $500,000 in 1928 for the construction of the first planetarium in the Western Hemisphere.

The Adler Planetarium was originally planned as a part of the Museum of Science and Industry.

The planetarium was originally considered for part of the Museum of Science and Industry, an endeavor led by Adler's brother-in-law Julius Rosenwald. Rosenwald was determined to convert the former Palace of Fine Arts of the 1893 World's Columbian Exposition into a museum, but was struggling to manage the many required renovations. These delays caused Adler to look elsewhere for a location. The South Park Commissioners, the precursor to the Chicago Park District, had just completed Northerly Island, the first of five intended (but otherwise never executed) recreational islands that were to be consistent with Daniel Burnham's 1909 Plan of Chicago. The Adler Planetarium and Astronomical Museum opened on Adler's birthday, May 12, 1930. The Chicago chapter of the American Institute of Architects awarded Grunsfield a gold medal for his design. The planetarium hosted the 44th meeting of the American Astronomical Society later that year.

The Webster Institute for the History of Astronomy cares for, studies, and interprets the Adler's collections. Since the opening of the Adler, the collection has grown to approximately 8,000 objects, books, works on paper, archival collections, paintings, and photographs. The Adler boasts the largest and most significant collection of historic scientific instruments in the Western Hemisphere, as well as one of the most significant collections in the world.

At the Space Visualization Laboratory (SVL), scientists, technology experts, artists, and educators work together to create new ways for people to virtually explore the Universe. Since its inauguration in 2007, the SVL has brought cutting edge research from scientists in the most prominent institutions around the country, as well as immersive and interactive technologies to the museum floor. In SVL visitors can experience new interactive and immersive visualizations, and attend presentations by astronomers and related researchers featuring these visualizations.

The Adler Citizen Science Department is also the U.S. headquarters of The Zooniverse, one of the world's leading citizen science platform and a global collaboration across several institutions that design and build citizen science projects. As of early 2014, the Zooniverse has engaged more than 1.1 million online volunteers as active scientists by discovering planets, mapping the surface of Mars, and detecting solar flares.

Far Horizons is the Adler's high-altitude balloon program. Participants design, build, and launch experiments flown to heights above 100,000 feet (30,000 m) on high-altitude balloons. The program offers real world opportunities for students and the community to participate in science, mathematics, physics, and engineering challenges.

Opened in 1977, the Doane Observatory is the largest aperture telescope available to the public in the Chicago area. With its 20-inch (510 mm; 51 cm) diameter mirror, the Doane can gather over 5,000 times more light than an unaided human eye, allowing guests to see celestial objects like the Moon, planets, stars, and galaxies that are trillions of kilometers, if not many light years, away. The original telescope, a 16-inch (410 mm; 41 cm) Cassegrain reflecting telescope built by the Adler optical and machine shop staff, was retired in 1987 and replaced with the current telescope.

In 2013, the Adler Planetarium announced undertook the first major renovation of the Doane Observatory. Completed in 2015, renovations included the addition of an indoor classroom, a restroom, HVAC systems, accessible entry ramps, and telescope and technology upgrades.

The Adler Planetarium is a member institution of the Large Synoptic Survey Telescope project.


The largest of Adler's domed theaters, the Grainger Sky Theater, offers audiences unique shows using the most immersive, technologically enhanced theater experience ever developed for a planetarium. The dome itself measures 21 metres (69 ft; 830 in) across. In 2008, when funding for an advanced projection system (part of a major renovation completed in 2011) was being debated in Congress, politician John McCain infamously characterized the upgrade as a new "overhead projector".

The Adler's second domed theater, the Definiti Theater, takes audiences on a spectacular journey in any one of its featured shows using an all-digital projection system.

The Adler's newly redesigned Samuel C. Johnson Family Star Theater allows audiences to the chance to see one "incomparable" show in dazzling, high definition 3D.


'Adler After Dark', the Adler Planetarium's 21+ evening event, was voted "Best After Hours Event" of 2013 by the Chicago Reader and "Best Date Night" by Chicago Parent. Guests at Adler After Dark have open museum access, themed programs, sky shows and views of the Chicago skyline. 'Astro Overnights' give families a chance to spend a night under the stars at the Adler. Guests have open museum access, a sky show and educational programming. The Astronomy Department at the Adler brings current topics in astronomy to guests through a quarterly lecture series.

The Adler hosts quarterly 'Hack Days', intended to encourage software developers, designers, scientists, engineers, artists and people who just like to create and build, to work together to solve problems. Participants at the Adler's summer camps build rockets, launch high-altitude balloons, and explore the edge of space. The Adler's hands-on summer camps are designed for children ages 5–14.
