The images projected on the 10-meter-diameter dome are much brighter and sharper than before, and I’m very satisfied with the quality. This upgrade has truly elevated our mission of making astronomy accessible and inspiring to everyone.
Illuminating the cosmos in Japan’s Astronomical Observatory
Japan - 2024
The universe has always been a source of wonder, inspiring humanity to explore and understand the vast expanse of space. At the National Astronomical Observatory of Japan (NAOJ), this sense of discovery is at the heart of its mission. Among its many contributions to public education and research is the 4D2U Dome Theater, a unique facility that brings the mysteries of the cosmos to life. Through stunning visualizations of celestial structures and their evolution, the Barco-powered Dome Theater offers audiences an immersive journey through space and time.

Context
Since its opening in 2007, the 4D2U Dome Theater has been a cornerstone of NAOJ’s outreach efforts. With a 10-meter dome screen and visualizations powered by advanced simulation and observation data, the theater has allowed visitors to experience the universe on a grand scale with unparalleled clarity and accuracy. Central to its mission is providing a space where both scientific discovery and public education flourish side-by-side.
Since 2015, its original Barco F35 projectors provided reliable service and delivered exceptional image quality. However, the theater’s projection system was beginning to show its age. With demand for higher-quality visuals, the time had come for an upgrade to reinvigorate the dome’s ability to inspire.
Challenge
Over the years, the technology that powered the Dome Theater had become outdated. The diminished brightness and resolution impacted the clarity and sharpness of the visuals, reducing the impact of the immersive experience that was central to the theater’s appeal.
The theater also needed to improve its ability to represent intricate celestial phenomena with high scientific accuracy. The growing demand for engaging representations, combined with the need to integrate footage from telescopes like Subaru, added urgency to the upgrade.
In short, the update is centered around visual clarity, audience engagement and a desire to maintain a cutting-edge experience for visitors.
Solution
Having used Barco’s projectors in its projects without issue, NAOJ trusted Barco’s quality, performance, and customer support for this revamp. The new system features six F80-Q7 units, equipped with advanced optical blending and active shutter 3D technology.
This upgrade with F80 projectors offers a significant leap in image quality with enhanced brightness and resolution capabilities, creating visuals that were sharper, more vibrant, and truer to the complex details of astronomical phenomena and data. With stereoscopic 3D capabilities integrated into the system, the Dome Theater installation allows audiences to experience depth and dimension like never before, bringing celestial structures to life in a way that feels almost tangible.
In addition, for NAOJ, this revamp needed to not only improve brightness and resolution but also achieve a seamless blending of visuals across the dome’s 10-meter diameter. The F80s optical blending ensured a seamless and distortion-free projection across the curved dome, maintaining the scientific accuracy that NAOJ prioritizes in its presentations.
The installation represents a continuation of the relationship between Barco and NAOJ, offering not only improved technology but also the confidence in dependable, high-quality support.
Results
The revamped theater reopened to the public on October 5, 2024, and immediately garnered acclaim for its breathtaking visuals. The improvements not only elevated the theater’s entertainment value but also reinforced its role as an educational resource, inspiring curiosity and a deeper appreciation for astronomy.
One of the most celebrated additions was the ability to display the starry skies above Mauna Kea, captured by the Subaru Telescope’s full-sky camera. This feature transported viewers to the summit of the Hawaiian volcano, providing a deeply immersive experience that highlighted the beauty of an unpolluted night sky.
Mr Isao Endo, Public Outreach Officer at NAOJ, expressed his satisfaction with the upgrade, stating: “The images projected on the 10-meter-diameter dome are much brighter and sharper than before, and I’m very satisfied with the quality. This upgrade has truly elevated our mission of making astronomy accessible and inspiring to everyone.”
The 4D2U Dome Theater now stands ready to inspire the next generation of explorers and dreamers, offering a brighter and sharper window into the wonders of the universe.
