At Zeiss-Planetarium Jena, a historic venue with deep roots in the evolution of planetarium design, a recent modernization effort has reframed the dome not just as a projection surface, but as a full learning environment. The renewed space is built to support astronomy presentations, fulldome films, concerts, educational events, and other immersive productions, making it a flexible public classroom as much as a cultural attraction. In that sense, the project speaks to a broader educational mission: using spatial design, image, and sound to help audiences engage with science, technology, and the arts in a setting that encourages curiosity and attention.
That mission matters because planetariums occupy a unique place in public learning. They can translate abstract scientific ideas into experiences that are visual, memorable, and shared. In the case of Jena, the renovation also carries symbolic weight: it connects a landmark of planetarium history to contemporary expectations for immersive education. The result is not simply a technical upgrade, but a renewed platform for public engagement—one that can support school groups, families, and general audiences in ways that feel both accessible and inspiring.
“The key was to treat the dome as a single architectural, acoustic and technological system,” explained Behrens. “The screen had to deliver a seamless image, the treatment behind it had to control the room, and the loudspeakers had to remain effective through the surface. None of those requirements could be resolved in isolation.” That statement captures an increasingly important lesson in immersive learning design: the best educational spaces do not separate content delivery from the room itself. Instead, they integrate acoustics, sightlines, and technology so that the audience can stay focused on the experience rather than on the mechanics of it.
The acoustic strategy developed for the cylindrical lower walls reflects that integrated thinking. By combining quadratic residue diffusers, broadband absorbers, and reflective surfaces, the design team aimed to reduce problematic focusing effects from the curved geometry while preserving enough liveliness to keep the room from feeling over-deadened. This kind of balanced treatment matters in educational venues because clarity and comfort directly influence comprehension. If spoken narration is easier to understand and the environment feels more evenly distributed, audiences are more likely to stay engaged with the science or story being presented.
Using the acoustic model, WSDG refined the placement and balance of the different treatments to promote an enveloping and evenly distributed sound field. For educators and exhibit designers, that matters because immersive learning works best when the environment supports multiple modes of attention at once: listening, looking, and emotionally connecting. A well-tuned dome can help a presenter guide audiences through complex topics like planetary motion, scale, or the structure of the universe with fewer distractions and more impact. It also opens the door for interdisciplinary programming, from astronomy talks to music performances, that can reach audiences who might not otherwise visit a science venue.
“Planetariums bring architecture, image and sound together in a uniquely immersive way,” said Behrens. “At Jena, the aim was to respect a landmark that helped define modern planetarium design while creating the acoustic conditions required for the next generation of planetarium experiences. It is a very special project because its historic engineering and contemporary technology are inseparable.” The quote points to a larger opportunity for the field: immersive spaces can honor heritage without becoming static. When they are thoughtfully updated, they can continue serving schools, museums, and the public as living tools for discovery.
The reopening of the modernized Zeiss-Planetarium Jena in July 2026, during its centenary celebrations, makes the project especially relevant as a model for the immersive education sector. It suggests that future-ready planetariums may need to be designed less as single-purpose projection halls and more as adaptable learning ecosystems. That approach could influence how institutions think about STEAM education, accessibility, and cross-disciplinary programming, while also broadening access to high-quality dome experiences. In that sense, Jena offers more than a renovation story: it offers a blueprint for how immersive venues can deepen learning while remaining culturally meaningful.
