Construction begins on massive underground neutrino experiment designed to unlock the secrets of the universe

Nearly a mile underground in South Dakota, scientists are building a world-leading experiment to study neutrinos and investigate some of the universe’s greatest mysteries, including how the universe took shape after the Big Bang and if neutrinos are the reason our world is predominantly made of matter. Currently, crews from Fermilab, CERN and SURF are assembling large steel beams to form the outer structure of the neutrino experiment’s massive detector modules.

The research space, more than 500 feet long and about seven stories tall, will house one of the experiment’s massive detector modules. Credit: Aaron Thompson, Fermilab

Momentum builds for world-leading neutrino experiment hosted by Fermilab

Construction of the Long-Baseline Neutrino Facility is entering its next phase, marking a major step forward for the international Deep Underground Neutrino Experiment hosted by Fermilab. With the arrival of critical components and growing momentum across partner institutions, DUNE is moving closer to unlocking long standing mysteries in particle physics and the origins of the universe.

Neutrino Day 2026

    Each year for Neutrino Day, SDPB hosts a special live broadcast a mile underground. This year, SDPB spoke with Mike Headley, SURF laboratory director, Dr. Sowjanya Gollapinni, senior scientist for Deep Underground Neutrino Experiment and others about DUNE and Neutrino Day events in Lead, SD.

    Fermilab marks 70 years of neutrino science and leads next-generation experiment

    As Fermilab commemorates 70 years since the discovery of the neutrino at the Savannah River Site in the United States, the lab also celebrates its multiple generations of pioneering neutrino research. Today, Fermilab is building the next era of neutrino discovery through the development of the world-leading Deep Underground Neutrino Experiment.
