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 ...

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 ...

Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together. The razor-thin chain of galaxies sits inside a much larger filament that ...

For the first time, scientists have used Earth-based telescopes to look back over 13 billion years to see how the first stars in the universe affect light emitted from the big bang. Using telescopes ...

Earth is under constant bombardment by cosmic rays, showers of high-energy particles that blast our planet from all directions at near light speed. While this might sound like the precursor to a ...

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 ...

Astronomers using NASA’s James Webb Space Telescope have created the clearest map yet of the universe’s “cosmic web” — the enormous hidden structure that connects galaxies across space. By analyzing ...

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 ...
