Cosmic rays are charged subnuclear particles that move close to the speed of light, constantly raining down on the Earth. These particles are relativistic, as defined by Albert Einstein’s special ...

Cosmic rays inside a dense molecular cloud were measured for the first time, helping scientists better understand how stars begin forming.

Astronomers have found compelling evidence that a supernova shock wave has produced a large amount of cosmic rays, particles of mysterious origin that constantly bombard the Earth. This discovery, ...

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, ...

The 10,000-year-old remnant of a supernova 2,600 light years away is acting like a giant particle accelerator, and it’s flinging cosmic rays out across the galaxy — like the Large Hadron Collider on ...

(Nanowerk News) Astronomers from the International Centre for Radio Astronomy Research (ICRAR), in collaboration with international teams, have made a startling discovery about a new type of cosmic ...

LIGO confirmed the existence of gravitational waves in 2015, detecting one-time perturbations of spacetime from the merger of large black holes. There should be a background of gravitational waves ...

The Large Hadron Collider at CERN is one of the most ambitious undertakings in particle physics. For nearly $5 billion, scientists were able to build a ring of superconducting magnets chilled to ...
