The most energetic particles in the universe – ultrahigh-energy cosmic rays – likely come from supermassive black holes in the hearts of nearby active galaxies, says a study by scientists from nearly ...

The most powerful cosmic-ray electrons and positrons ever detected slamming into Earth's atmosphere carry energies so high they can only have come from relatively close by, new research has revealed.

At times, the sun ejects energetic material into space, which can have consequences for space-based and even ground-based ...

Spencer Axani, assistant professor in the Department of Physics and Astronomy, is the inventor of CosmicWatch, a portable, ...

You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics.

Particles raining down from space offer 3-D views inside swirling tropical storms. Muons created from cosmic rays that smash into Earth’s upper atmosphere have revealed the inner workings of cyclones ...

To reach this conclusion, scientists studied millions of data points captured by a cosmic ray detector on the ISS. When you purchase through links on our site, we may earn an affiliate commission.

CHICAGO (Reuters) - Ultra-high energy cosmic rays -- particles that pack the punch of a rifle shot -- make their way to Earth from massive black holes in nearby galaxies, scientists said on Thursday, ...

The 10,000-year-old remnant of a supernova 2,600 light years away is acting like a giant particle accelerator, and it’s flinging cosmic rays out across the galaxy — like the Large Hadron Collider on ...

Ben may have been right way back when Stan Lee and Jack Kirby created him and the rest of the Fantastic Four 64 years ago, but we know a heck of a lot more about cosmic rays today. Back then, Grimm, ...

Researchers have used cosmic rays from deep space to create a powerful probe to investigate the hidden mysteries of the Great Pyramid of Giza. The team, including Fermilab High Energy Physics (HEP) ...
