Adler Planetarium

The Adler Planetarium is a public museum for astronomy in Chicago, Illinois, United States. It is run by the Chicago Park District and was the first planetarium ever built in the United States. It was founded in 1930 by a local businessman named Max Adler.

Located on the northeastern tip of Northerly Island on Lake Michigan, the Adler Planetarium is part of Chicago's Museum Campus, which also includes the Shedd Aquarium and the Field Museum of Natural History. The planetarium's goal is to help people explore and understand the universe.

The Adler Planetarium opened to the public on May 12, 1930. Its building was designed by an architect named Ernest A. Grunsfeld Jr. In 1987, the planetarium was named a National Historic Landmark. Today, it has three theaters, space science exhibits, including the Gemini 12 space capsule, and a collection of old scientific instruments. It also has a public observatory. Around the planetarium are several sculptures, such as Man Enters the Cosmos by Henry Moore.

History of the Adler

Establishment

In 1913, a man named Oskar von Miller asked a company to make a special machine. This machine could show pictures of stars and planets on a rounded ceiling. This idea was called a planetarium when it was first shown in 1923. The idea became very popular.

A man named Max Adler, who lived in Chicago, Illinois, wanted to build a planetarium there. He heard about one in Munich and decided to build the first one in the Western Hemisphere.

The planetarium was built on an island in Chicago. It opened on May 12, 1930, which was Max Adler’s birthday. Later that year, it hosted an important meeting for astronomy experts.

2025 – Elizabeth Babcock becomes the new leader of the Adler Planetarium.

Research

The Adler Planetarium’s Astronomy department and Webster Institute for the History of Astronomy do research and share what they learn with scientists and the public.

Astronomers at Adler study many parts of space science, including planetary geology, star formation, gamma-rays, and using telescopes to watch the skies.

The Collections department cares for and studies the planetarium’s collections, which have grown to about 8,000 items such as objects, books, paintings, and photographs. The Adler keeps special archives from Derek J. de Solla Price, Michael J. Crowe, and Jim Lovell, along with the biggest group of historic science tools in the Western Hemisphere.

The Space Visualization Laboratory started in 2007 to let people explore the universe using computers.

The Adler Citizen Science Department is the U.S. home of The Zooniverse, a citizen science website where people work together to help scientists.

Far Horizons is a program where students and others design and build experiments to fly on balloons higher than 100,000 feet. This gives them real chances to work on science, math, physics, and engineering problems.

The Doane Observatory, opened in 1977, is the biggest telescope that the public can use in the Chicago area. Its 20-inch mirror collects much more light than human eyes can see, letting visitors view the Moon, planets, stars, and faraway galaxies.

The Adler Planetarium is part of the Large Synoptic Survey Telescope project.

Theaters

The Adler Planetarium has two special domed theaters and one regular theater. The biggest one is called the Grainger Sky Theater. Its dome is 21 meters (about 69 feet) wide. In 2008, a politician named John McCain made a funny comment about the new projection system they were planning.

Programs

The Adler Planetarium has special events for different visitors. "Adler After Dark" is an evening event for adults over 21. Guests can explore the museum, enjoy activities, and watch sky shows.

"Astro Overnights" let families spend a night under the stars. They get museum access, a sky show, and learn about space.

The planetarium holds "Hack Days" every few months. These bring together people who love creating things, like software developers, designers, and artists, to solve problems together. In summer camps for kids ages 5 to 14, children can build rockets, launch balloons, and learn more about space through hands-on activities. The Astronomy Department shares space news through talks every three months.
