The realm of immersive science and cultural storytelling is witnessing a revolutionary leap with the introduction of Europe’s first LED dome at the Prague Planetarium. Around the world, planetariums and immersive venues are evolving into multifaceted hubs that blend education, entertainment, and technology. Recent global developments underscore the rising demand for cutting-edge presentation formats that offer audiences breathtaking clarity and interactivity. According to a 2024 report from the International Planetarium Society, audiences are increasingly drawn to venues that provide not only astronomical education but also diverse multimedia experiences that extend beyond traditional star shows. The Prague Planetarium’s transformation exemplifies this trend by embracing state-of-the-art LED technology that enhances both visual quality and experiential immersion.
The historic Prague Planetarium, with its roots stretching nearly a century, had long been a beacon for astronomy education in the Czech Republic. After a comprehensive renovation, it emerged as a technology leader, featuring a 22-meter, 8K+ LED dome powered by Cosm’s innovative CX System. This upgrade marks a pivotal moment in planetarium technology. Martin Fuchs, the planetarium’s creative director, explained, “When I arrived at the planetarium in 2018, the projectors and electronics were well beyond their lifetime. The dome itself was still the original from the 1950s. So, we decided to rebuild the planetarium completely” (Fuchs, blooloop.com). This decision reflects a wider industry acknowledgement that legacy projection systems, while iconic, increasingly fail to meet the demands of modern immersive storytelling.
One of the most compelling advantages of the CX System’s LED dome is its ability to deliver true immersion by eliminating traditional sightline issues associated with projection-based systems. Kirk Johnson, COO of Cosm, highlighted, “With LEDs emitting the light directly, we were able to bring the display right down to where visitors stand and even integrate the seating platform into the dome itself. That means you’re not just watching what’s on the dome—you’re sitting inside it” (Johnson, blooloop.com). This direct lighting approach overcomes challenges such as shadows and light spillage that diminish image quality in traditional domes. For practitioners and designers of immersive environments, such advancements present opportunities to rethink spatial design and audience interaction within domed venues, making the experience more enveloping and participatory.
Another significant feature that distinguishes the Prague Planetarium’s transformation is the integration of Cosm’s CX System with Unreal Engine, a real-time 3D creation platform widely used in gaming and virtual production. This fusion allows live rendering of ultra-high-definition content, enabling interactive explorations of immersive worlds. Johnson elaborated, “We now have a direct interface with it, which opens up a whole new range of possibilities. Beyond traditional video playback and astronomy content, creators can now leverage everything Unreal offers” (Johnson, blooloop.com). This advancement ushers in a new era for content creators who can develop dynamically rendered shows, multi-genre presentations, and hybrid performances that were previously impossible in fulldome environments.
The implications for the fulldome and immersive cinema industry are profound. The Prague Planetarium’s LED dome sets a new benchmark for brightness, resolution, contrast, and operational longevity, posing a challenge and inspiration for content producers and venue managers worldwide. Higher contrast ratios and vibrant colors enable the presentation of diverse programs, from dazzling astronomical simulations to richly detailed natural landscapes, cultural narratives, and technological showcases. This diversity can attract broader audiences, extend programming possibilities, and enhance educational impact by supporting varied learning styles and interests. For fulldome filmmakers and software developers, the coupling of LED tech with real-time rendering engines like Unreal opens unprecedented creative potential to craft interactive and narrative-rich immersive experiences.
Moreover, the sustainable nature of LED technology — with a lifespan around 100,000 hours and far greater energy efficiency than traditional projection systems — aligns with growing environmental and operational concerns across museums and science centers. Venues can plan for long-term use without frequent costly replacements, while also reducing their carbon footprint. This foresight makes LED domes an attractive investment, helping ensure the vitality and future relevance of immersive venues in the cultural and educational landscape.
As immersive venues like the Prague Planetarium pioneer these advances, they catalyze a redefinition of what dome theatres can offer. They are no longer just venues for observing stars but vibrant multimedia stages that invite deeper engagement and exploration. Content creators, educators, and technologists are thus called to envision and realize new forms of storytelling that leverage the full capabilities of these LED systems and real-time content engines, pushing the boundaries of audience immersion and interactivity in the fulldome sector.
