At Brookhaven National Laboratory on Long Island, the Relativistic Heavy Ion Collider has powered down for the last time, ending operations at the only particle collider still running in the United ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

Before the RHIC shut down, it was the only operational particle collider in the U.S. and one of two heavy-ion colliders in the world, the other being the Large Hadron Collider at CERN in Switzerland.

A neutrino with almost unimaginable energy slammed into Earth in early 2023, carrying roughly 220 petaelectronvolts, far beyond anything human machines can produce. The event, tagged KM3-230213A, has ...

A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole ...

When the universe first burst into being, all of space was a cosmic cauldron filled with a roiling, fiery liquid of ...

The Relativistic Heavy Ion Collider , the largest particle collider in the United States, collided its last particles in early February. RHIC is a massive accelerator ring and set ...

After 25 years, Brookhaven National Laboratory’s Relativistic Heavy Ion Collider—the U.S.’s largest particle collider—has ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic ...

A new data center has been built at IN2P3, France’s nuclear and particle physics research body. The VIL3 data center, at ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that ...

At a fundamental level, what is our Universe made of? This question has driven physics forward for centuries. Even with all the advances we've made, we still don't know it all. While the Large Hadron ...
