A century after their discovery, cosmic rays—particles of extreme energy originating from the far reaches of the ...

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 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.

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 ...

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 ...

For scientists studying the impacts of space weather, one of the central mysteries of solar flares. Solar flares are the colossal release of magnetic energy in the Sun’s atmosphere that erupts with ...

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 ...

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 ...
