What makes up the matter we perceive in the universe? To start, there are the usual suspects, like electrons, protons, quarks and neutrinos. But if those particles aren't strange enough for you, I'm ...

A new study broadens the horizon of knowledge about how matter behaves under extreme conditions and helps to solve some great unknowns about the origin of the universe. An international team of ...

TRONDHEIM, Norway — Particles racing through space at nearly the speed of light pack energy millions of times greater than anything we can create on Earth. For decades, these cosmic bullets have ...

A comprehensive review explores how particles containing heavy quarks (known as charm and bottom hadrons) interact in a hot, dense environment called hadronic matter. The authors have published a ...

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 ...

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from outside ...

For more than half a century, scientists have tried to understand dark matter—a mysterious form of matter that doesn’t emit or absorb light but is thought to make up most of the universe’s mass. Its ...

"It's astonishing to find such a strong radio signal at this distance." A vast cloud of energetic particles surrounding a cluster of galaxies that existed around four billion years after the Big Bang ...

In many ways, Lina and Neriman's refugee journey from Iraq to Utah parallels that of a cosmic ray: covering great distances, ...
