The universe looks like it is mostly empty space. Remove the stars, planets, dust, and gas, and what remains is nothing at ...

A vast cloud of energetic particles surrounding a cluster of galaxies that existed around four billion years after the Big Bang could help scientists discover how the early universe took shape. But ...

A single subatomic particle that hit Earth in 2023 carried roughly 100,000 times more energy than anything humanity has ever produced in a particle collider. It was a neutrino, one of nature’s most ...

A deep-sea neutrino telescope has detected the most energetic neutrino ever recorded. The particle, known as a "ghost particle," was about 30 times more active than the previous record-holder.

NASA used a radiation-tested camera in the Artemis II mission after successful ground testing with high-energy particles at GSI and FAIR facilities.

Physicists provide a viable and testable explanation for how UHECRs are created. Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million ...

In the exotic world of particle physics, neutrinos may be the most mysterious members. They rarely interact with other matter ...

For decades, nuclear fusion has held the promise of clean, limitless energy. However, one persistent challenge has slowed progress: the inability to reliably contain the high-energy particles needed ...

MELBOURNE, FLA.—Florida Institute of Technology researchers are trying to solve one of the great mysteries in nature: how thunderstorms make lightning. Because, in principle, lightning is a big spark ...

Nuclear fusion, an energy generation method driven by the combination of two hydrogen atoms, has long been sought for its potential as a near-limitless source of energy. In the pursuit of cheap and ...

Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million times what can be achieved by humans. But while the existence of UHECRs has been ...
