# Translating Cosmic Fast Radio Bursts Into Audible Sound A Finnish cathedral installation sonifies mysterious radio pulses from distant galaxies. - **Source:** [Space.com](https://www.space.com) - **Published:** 2026-11-11 - **Topic:** [science](https://brifing.si/c/science) - **Original article:** - **On Brifing:** https://brifing.si/s/58b393c5-9bd8-46e5-9a30-412f73431fb9 ## Invisible Cosmic Energy Fast radio bursts are intense, millisecond-long energy flashes originating from distant galaxies. Since their 2007 discovery, astronomers have detected thousands of these events, yet their exact origins remain a scientific mystery. These bursts release as much energy in a single millisecond as the sun produces over three full days of operation. ## CHIME Telescope Data The Canadian Hydrogen Intensity Mapping Experiment, located in British Columbia, revolutionized FRB detection. Between 2018 and 2023, this facility recorded 4,539 distinct bursts from 3,641 separate sources. By utilizing a wide field of view and advanced supercomputing, CHIME significantly increased the volume of known cosmic signals available for researchers to study. ## Artistic Sonification Process Composer Andrew Melchior and MIT physicist Kiyoshi Masui collaborated to translate raw radio data into acoustic signals. By mapping the structure of each real signal to varying musical pitches, they created an installation called The Logos. This project allows human ears to perceive cosmic phenomena that are otherwise completely invisible to us. ## Oulu Cathedral Installation The installation at Oulu Cathedral in Finland features 12 loudspeakers distributed throughout the space. Since early April, visitors have experienced the sounds of distant FRBs, which manifest as humming, rumbling, popping, and whistling tones. The exhibit is scheduled to remain open to the public through the end of the year 2024. ## Ancient Cosmic Signals The signals utilized in the installation vary significantly in age, reflecting the vast distances they traveled. The youngest bursts in the collection are approximately 50 million years old, while the oldest date back 8 to 9 billion years. These sounds represent a unique bridge between modern human technology and ancient cosmic history. ## Physics of Sound Dispersion Physics dictates the specific auditory experience of the installation. As radio waves travel through intergalactic gas, high frequencies arrive first, followed by lower frequencies. This dispersion effect creates a downward sweep in pitch, which Melchior captures as the sound falls from the cathedral dome, providing a literal representation of cosmic travel. ## Magnetar Origin Theories Recent observations using the James Webb Space Telescope identified a distant FRB in a young, star-forming dwarf galaxy. This finding challenges theories suggesting FRBs originate from merging neutron stars, which require billions of years. Instead, evidence increasingly supports the magnetar theory, where young, highly magnetic neutron stars produce bursts after massive explosions. ## Future Live Performance On November 21, the project will culminate in a live performance at Oulu Cathedral. Thirty singers will interact with the sonified bursts, singing in Finnish while Melchior plays live keyboard accompaniments. This event aims to create a layered, immersive experience that highlights the journey of signals across billions of years. ## Sources covering this story - https://www.space.com/astronomy/we-cant-see-fast-radio-bursts-but-we-can-now-hear-them-thanks-to-a-finnish-cathedral — --- _Summary written by Brifing from the original reporting.
