Henry B. duPont III Planetarium
Digital and Live Full-Dome Planetarium Shows
Our digital full-dome theater features a seamless 33-foot diameter dome and a dual-projector 4k laser projection system. Digistar 2025 by Evans & Sutherland transforms our planetarium into a virtual starship, creating real-time visualizations that transport our audience to other planets, star systems, and beyond. Our planetarium also screens pre-recorded shows on a variety of topics including spaceflight, aviation, biology, and history.
We have an audience capacity of 65 seats for regular shows, with the ability to expand to 85 seats for special events. All seats are removable for easy accessibility.
Admission to public shows requires a media pass, which can be purchased at the front desk. One media pass grants admission to all planetarium shows and special presentations for the day.
The planetarium is also available for private bookings and events, including school trips, scout groups, birthday parties, corporate events, and weddings. Contact us for more info.

Astronomy After Dark
Our new Astronomy After Dark series is designed for ages 13+ and will feature content for true space enthusiasts. Join us for a chance to nerd out with like-minded community members in these deep-dive space explorations.
Astronomy After Dark features a curated selection of digital planetarium shows that dive deeper into space than our typical planetarium programming, as well as unique live programming expanding on interesting topics in astronomy. How do we measure the distance to objects in space? What do we know about the evolution of stars? How do we categorize and study galaxies? Learn the answers to these questions and more in Astronomy After Dark!
Shows run between 30-45 minutes. Please be aware that Astronomy After Dark is geared towards an adult audience and viewers younger than 13 may be asked to leave to respect others' experience.
Entry at or after 6 p.m. requires only a media pass--no general admission required! Doors close promptly at 6:15 and no late entry will be permitted.
