Henry B. duPont III Planetarium

Discover the wonders of the night sky

When the room is darkened, the dome is transformed into a realistic simulation of the starry sky. The images that are created completely envelop viewers’ senses for an immersive theater experience.

Planetarium shows suitable for very young children and for those over eight years old run daily and are approximately 20 – 35 minutes long. Cost is included in general admission.

The Henry B. duPont III Planetarium was recently upgraded thanks to the generosity of the duPont Family and The Birkmaier Fund.

The Birkmaier Fund

The Birkmaier Fund was created in tribute to Leslie E. Birkmaier, former Director of the Henry B DuPont III Planetarium at The Discovery Museum and Planetarium, and its original incarnation as the Museum of Art, Science, and Industry. He served as Planetarium Director, as well as other museum capacities, for 42 years, from January of 1962 to October of 2004.

Leslie left a legacy of hundreds of thousands, young and old, who were introduced to the wonder and beauty of the night sky through his engaging, spirited Planetarium lectures. In tribute to his tireless work, the Leslie E. Birkmaier Fund was founded to underwrite on-going Planetarium improvements and provide scholarship dollars to young astronomy scholars in the formative stages of their career.

About the Henry B. duPont III Planetarium

The Henry B. duPont III Planetarium has served our region for over 50 years. When the Planetarium first opened in 1962, space exploration was new — it would still be several years before astronauts landed on the Moon. Recognized at its opening as one of 12 major planetarium facilities in the nation, the Planetarium has since been upgraded to incorporate digital projection, new seats, and enhanced lighting and sound systems.

The Planetarium was named in 1976 in honor of Henry B. duPont III, a long-time Museum Board member and the Chair of the Planetarium Committee. Mr. duPont was a fervent and generous supporter of the Planetarium and its learning programs, and the Museum thanks his family for their ongoing support for STEM learning and Planetarium programs.
