Adler Planetarium and Astronomy Museum

Adler Planetarium and Astronomy Museum, Chicago

The Adler Planetarium & Astronomy Museum in Chicago was the first planetarium built in the Western Hemisphere and is the oldest in existence today.

The Adler has three full-size theaters. Since the museum's opening in 1930, visitors view representations of the night sky in the historic Sky Theater planetarium, the outer protective dome of which is visible from the exterior of the building. The Zeiss Planetarium projector is capable of accurately reproducing the movement of every aspect of the night sky.
