About Zacheis Planetarium

The Harry Zacheis Planetarium and Observatory was completed in 1964 using only privately donated funding. It was completely renovated in 2012 as part of a grant from the U.S. Department of Education.

It is located on Richardson Ave. between the art and business buildings, right on the Richardson Hall lawn. Free public parking is available on the street.

Planetarium interior before renovation

Planetarium renovation:  As part of a 5-year grant from the U.S. Department of Education, Zacheis planetarium has been completely renovated. The goal of the grant is to increase enrollments and graduates in STEM (science, technology, engineering, and math) fields, particularly among Hispanic students. Among other things, the grant also includes the completion of the third floor of the science building and the construction of a new observatory at the north end of campus which houses most of our telescopes.

The planetarium, which can seat 45, now has a Spitz SciDome 1600 projector, capable of projecting a 1600-pixel diameter circle on the screen. The screen is a top-of-the-line Nanoseam dome, also by Spitz. The renovation also included all new carpet and seating.

We currently have approximately 50 professionally produced full-dome shows in our library, including “Space School”, “Cleopatra’s universe”, “Seven Wonders”, “Dream to Fly”, “Stars of the Pharaohs”, “Escher’s Universe”, “Lamps of Atlantis”, and “Bella Gaia”. The full list can be found on our Movie Library page.

    • The Zacheis planetarium is at the south end of the Adams State College campus, between the art building and the business building. It is just off Richardson Ave, which has on-street parking. On June 5th we will have telescopes set up outside for viewing the transit, though the theater will be closed for renovations.
