Kiyoshi Masui Helps Transform Deep-Space Signals into Cathedral Sound
A new immersive sound installation at Oulu Cathedral, Finland, brings the research of astrophysicist Kiyoshi Masui into a striking sensory form, transforming more than 4,000 cosmic signals into spatial audio.

Opening on Easter Sunday, The Logos invites visitors to experience deep-space phenomena not as distant abstractions, but as something immediate and resonant. The project is led by artist and creative technologist Andrew Melchior in collaboration with Masui, philosopher Timothy Morton, and cathedral dean Satu Saarinen. Together, they treat the cathedral, built in 1832, not just as a setting but as part of the instrument itself. Its stone surfaces and reverberant acoustics give physical presence to signals that have travelled from distant galaxies.
At the heart of the installation is data gathered by the CHIME radio telescope, which detects Fast Radio Bursts (FRBs). FRBs are immensely energetic flashes lasting only milliseconds and originating in distant galaxies across the observable universe. The Logos represents one of the most extensive artistic sonifications of FRB data to date. Each day at noon, the cathedral is filled with a one-hour procedural composition derived from these bursts. Some bursts are singular events, never repeating, while others pulse again and again from unknown sources. These patterns remain one of astrophysics’ most compelling mysteries.
The fast flashes will echo as snare-like beats bouncing through the cathedral,” said Masui. “The sweeping dispersion of the signal — where different radio frequencies arrive at slightly different times — creates harmonies between high and low tones. It should feel rich and layered, while also revealing something real about how these signals travel across billions of years of cosmic space before reaching Earth.
Running through April 2027 to mark the cathedral’s 250th anniversary, The Logos will feature as part of Oulu2026 European Capital of Culture, and the Lumo Art & Tech Festival. By converting FRB data into a shared listening experience, the collaboration suggests a different way of understanding the universe: not only through analysis, but through attention.
