Collider Beacon

"Collider Beacon" is an aerial installation consisting of a powerful beam of light that slowly rotates over the Museo de Arte Moderno's Sculpture Park, functioning like a timekeeper or a sky-scanning radar. The beam’s intensity subtly flickers in real time, responding to otherwise invisible cosmic radiation measured by a custom-built sensor displayed at the museum’s entrance. The sensor, composed of a dozen Geiger counters arranged to read directional data, detects the angle at which muons strike the Earth, and this live information directly modulates the beacon's brightness.

Cosmic rays—high-energy particles such as protons and alpha particles originating from stars, supernovae, and black holes—constantly bombard the planet. When they collide with the upper atmosphere, they produce showers of secondary particles, including muons: short-lived, highly penetrating particles that reach the Earth’s surface and are registered by the sensor. The installation serves as an observatory for this ceaseless radiation, a phenomenon that, while harmful without the atmosphere's protection, is also partly responsible for the genetic mutations essential to the evolution of all life on Earth.

Earlier iterations of this “collider” series were exhibited at Lulu Island in Abu Dhabi (2023) and across the façade of Herzog & de Meuron’s Parrish Museum in Watermill, New York (2025).
