In 1991, the University of Utah Fly's Eye experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray's energy shocked astrophysicists. Nothing ...

Using data from NASA's James Webb Space Telescope (JWST), astronomers led by researchers at the University of California, Riverside have produced the most detailed map of the cosmic web ever made, ...

The original version of this story appeared in Quanta Magazine. Of the 100 trillion neutrinos that pass through you every second, most come from the sun or Earth’s atmosphere. But a smattering of the ...

Re-creating a piece of the universe in a bottle might sound like science fiction, but it’s exactly what Linda Losurdo did. Losurdo, a doctoral student in materials and plasma physics at the University ...

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of ...

More than 600 feet below the surface of Antarctica, ultrasensitive detectors picked up the tracks of cosmic rays crashing down from outer space. The Askaryan Radio Array is a group of sensors drilled ...

The propagation of energetic charged particles and cosmic rays in magnetized thermal plasma is focused. We consider a four-fluid system that consists of thermal plasma, cosmic rays, and two opposite ...

Artist’s illustration of the extremely energetic cosmic ray observed by a surface detector array of the Telescope Array experiment, named “Amaterasu particle.” In 1991, the University of Utah Fly’s ...

Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics. Of the 100 trillion neutrinos that pass ...
