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, ...

Astronomers have detected an enormous γ-ray bubble that could be a source of the Milky Way’s most powerful cosmic rays — high-energy particles that rain down on Earth from space. The turbocharged ...

Researchers recently detected an "ultra-high-energy" cosmic ray, which is the most powerful since the famous "Oh My God" particle was detected in 1991. They have no idea where it came from. When you ...

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 ...

The Auger collaboration, which operates a cosmic ray observatory spanning 3000 km2 (~1158 sq mi) in the Argentine Andes, announces the observation of an unexpected structure in the spectrum ...

When you have a lot of responsibilities, like family, work, keeping a household running, and taking care of yourself, it can be exhausting. You feel like you don’t have the physical and mental energy ...

The “Oh-My-God” particle has a new companion. In 1991, physicists spotted a particle from space that crashed into Earth with so much energy that it warranted an “OMG!” With 320 quintillion electron ...

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 ...
