The origins of extremely high-energy particles that fill the universe—such as protons, electrons, and neutrinos—remain one of the longest-standing mysteries in modern astrophysics. A leading ...

A picture of the NOvA "far detector" located in Minnesota. Neutrinos sent from Fermilab's NuMI (Neutrinos at the Main Injector) beam travel 810 kilometers underground to reach this detector. Very ...

Why is there something instead of nothing? Versions of that metaphysical chestnut have troubled philosophers and physicists for centuries. Now, combined results from two research teams that study ...

On February 13, 2023, a single subatomic particle zipped across the Mediterranean Sea off the coast of Sicily, triggering thousands of sensors. This neutrino, or“ghost particle,” is the most energetic ...

At MIT’s Formaggio Lab, Peña’s work may help researchers pinpoint the elusive particle’s mass—and refine the fundamental laws of physics in the process. Growing up in South Central Los Angeles, Junior ...

Physicist Carlos Argüelles-Delgado gives us an introduction to this one-of-a-kind facility, one of the most successful neutrino detectors in the world. Reading time 6 minutes Neutrinos are strange ...

Neutrinos are fundamental particles characterized by no electric charge and very small masses, which are known to interact with other matter via the weak force or gravity. While these particles have ...

Physicists have caught neutrinos from a nuclear reactor using a device weighing just a few kilograms, orders of magnitude less massive than standard neutrino detectors. The technique opens new ways to ...

On July 21, 2000, the DONUT collaboration at Fermilab announced the detection of tau neutrinos for the first time. Here are a few ideas for celebrating 25 years of the most elusive of elusive ...

The neutrino is a notorious troublemaker in the world of particle physics. This tiny, elusive particle with no electric charge likely permeates every corner of the universe, but you’d be hard-pressed ...
