Holcomb Observatory and Planetarium, Public observatory at Butler University in Indianapolis, United States.
The Holcomb Observatory houses a 38-inch Cassegrain reflector telescope, which stands as the largest astronomical instrument in the state of Indiana.
The observatory opened its doors in November 1954 through funding from James Irving Holcomb and his wife as a centennial gift to Butler University.
The facility maintains research programs focused on asteroids, eclipsing variable stars, exoplanets, and long period variables in globular star clusters.
The observatory offers public viewing sessions through its telescope at no cost, while planetarium shows require admission fees of $8 for adults.
The building features a distinctive terrazzo floor decorated with zodiac symbols and includes interactive touch screens for exploring the solar system.
