Using a particle accelerator, an NYU professor partnered with an international team of researchers in Switzerland to recreate ...

Proton-oxygen collisions at the LHC reveal how extreme cosmic rays trigger particle showers when they slam into Earth’s atmosphere.

A neutrino from space recently plunged into the Mediterranean Sea with an energy that blows all other known neutrinos out of the water. Packing a punch of some 220 million billion electron volts, this ...

In 1991, an experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power ...

More than one million sources of energy are featured in the first X-ray images from the eROSITA space telescope. By Laura Baisas Published Feb 5, 2024 12:00 PM EST Add Popular Science (opens in a new ...

A faint hydrogen signal from a 5-billion-year-old universe emerged after astronomers stripped away overwhelming radio foregrounds.

Some of the most energetic cosmic rays in the galaxy may come from a surprisingly small source. If Max Planck Institute for Astrophysics researcher Laura Olivera-Nieto and her colleagues are right, ...

New research suggests that these ultra-high energy rays derive their energy from magnetic turbulence. Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments -- like the ...

An artist's rendition of the detection of the cosmic ray by the Telescope Array experiment. When high-energy cosmic rays reach Earth's atmosphere, they collide with and break apart atomic nuclei, ...

Massive stars know how to go out in style. Some of the brightest, longest-lived flares probably come from megastars getting shredded by supermassive black holes, researchers report in the June 6 ...
