Physicists at CERN have directly measured proton-oxygen collisions at 9. 62 TeV per nucleon pair, closely recreating an ...

Every second, particles zip through your body at nearly the speed of light. They rain down from a storm high in the sky, ...

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 ...

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 ...

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 ...

A new analysis of more than 1,700 supernovae is questioning whether the universe is really accelerating at all. After accounting for the ages of the stars that produce these explosions, researchers ...

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, ...

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, ...
