The Logos: 4,000 cosmic signals transformed into sound in Oulu Cathedral

Share

A year-long immersive sound installation transforming more than 4,000 cosmic signals into spatial audio opens on Easter Sunday inside Oulu Cathedral as part of Oulu2026 European Capital of Culture. The opening will be celebrated on Holy Saturday, 4 April, at 21:00.

The Logos, created by artist and creative technologist Andrew Melchior — whose work has previously spanned projects with David Bowie, Björk and Massive Attack — in collaboration with MIT astrophysicist Kiyoshi Masui, philosopher Timothy Morton and Oulu Cathedral Dean Satu Saarinen, will also feature in the Lumo Art & Tech Festival in November 2026.

A new sound installation opening at Oulu Cathedral on Easter Sunday will transform more than 4,000 mysterious cosmic signals into immersive spatial audio.

Created by British-German artist and creative technologist Andrew Melchior in collaboration with Kiyoshi Masui of the MIT Kavli Institute, philosopher Timothy Morton of Rice University, and cathedral dean Satu Saarinen, The Logos turns real astrophysical data into a daily sonic ritual inside the historic cathedral.

The opening celebration will take place on Holy Saturday, 4 April, at 21:00 at Oulu Cathedral, with free admission. The installation opens officially on 5 April and will remain on view for a full year, until April 2027, coinciding with the cathedral’s 250th anniversary.

Each day at noon, The Logos presents a one-hour procedural composition, filling the neoclassical cathedral — designed by Carl Ludvig Engel in 1832 — with sonified data from the CHIME radio telescope in British Columbia, Canada, the most prolific detector of Fast Radio Bursts.

In addition to its regular daily opening hours from 12:00 to 13:00, the Logos will be open in April as follows:

5 April, 13:00–16:00
6 April, 13:00–20:00
7 April, 12:00–17:00
9 April, 12:00–17:00
10 April, 12:00–16:30

Cosmic signals from billions of light years away

Fast Radio Bursts (FRBs) are intense flashes of radio energy lasting only milliseconds, originating from sources billions of light years away. First detected in 2007, their origins remain one of astrophysics’ great mysteries.

The CHIME/FRB collaboration now detects several bursts per day and has catalogued more than 4,000 to date. The Logos represents one of the most extensive artistic sonifications of Fast Radio Burst data ever undertaken.

“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.”

Listening across deep time

For Melchior, the installation explores how humans encounter phenomena that vastly exceed ordinary scales of time and perception.

“These signals have travelled billions of years through space before reaching Earth,” Melchior said. “The Logos brings these extraordinary ancient signals into this inner space — not to explain them, but to listen with them.”

“Listening across billions of years might sound abstract,” Morton said. “But when we actually hear something, it becomes intimate. The vastness of cosmic time doesn’t push us away — it reminds us of our own bodies, our own capacity to listen, here on Earth.”

A shared space for listening

“People are in the same cathedral space, listening to the same sound, yet each experiences it in their own unique way,” Saarinen said. “It is wonderful to welcome a work like this to Oulu Cathedral — a place that has gathered people together for centuries. Bringing the sounds of the universe into this space invites us to reflect on both the vastness beyond us and the shared human experience of listening.”

Year-long programme of performances and public events

Alongside the daily noon ritual, The Logos will host performances and public events throughout 2026–2027, including appearances by Helsinki-based artist Heli Hartikainen and ambient music pioneer Alex Paterson of The Orb, as well as community choirs and talks exploring the intersection of art and astrophysics.

A new work titled Requiem for the Air That Held Us by Andrew Melchior and Miikka Lehtoaho will also premiere as part of the programme.

An interactive VST instrument allowing musicians and audiences to experiment with sonified Fast Radio Burst data will be available as a free download at www.thelogos.art.

About The Logos

The Logos is a year-long immersive sound installation at Oulu Cathedral (5 April 2026 – April 2027) commissioned as part of Oulu2026 European Capital of Culture. It transforms astrophysical data from more than 4,000 Fast Radio Bursts detected by the CHIME radio telescope into daily one-hour procedural compositions. The installation also features in the Lumo Art & Tech Festival (November 2026). Further information: www.thelogos.art
