Holcomb Observatory and Planetarium

Holcomb Observatory is an astronomy center located on Butler University's campus in Indianapolis with a large telescope available for public viewing. The building also features a planetarium with shows presented under a dome ceiling, along with interactive displays about space.

The facility was built in 1954 as a centennial gift to the university from a private donor and his wife. Since its opening, it has remained a key site for astronomical observation and education on campus.

This facility serves as a gathering place where visitors of all ages come to explore the night sky and learn about astronomy together. The planetarium shows bring the cosmos to life on a dome ceiling, making celestial discoveries feel personal and immediate.

The observatory welcomes visitors during daytime and evening hours with free access to the telescope, while planetarium shows have a small admission fee. It is helpful to check opening hours in advance, as weather and special events can affect when the facility is accessible to the public.

The floor inside the facility features zodiac symbols rendered in shimmering terrazzo, creating a striking visual element as soon as you walk through the doors. This decorative detail transforms the entrance into part of the astronomical experience itself.
