Again last week Dr. Robert Andrews Millikan reiterated that the universe is constantly being regenerated. Sir James Hopwood Jeans, and others, argue that it is blowing into wavy smithereens. While 100 ...

For thousands of years, archaeologists and grave robbers have searched every nook and cranny of the Great Pyramid, second-to-last resting place of the ancient Egyptian ruler Khufu — but the ancient ...

The Large High Altitude Air Shower Observatory (LHAASO) has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time that the origin ...

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 ...

Cosmic rays, high-energy particles that travel through space, have puzzled scientists for decades. One particular feature of their energy spectrum—the “knee”—has long remained a mystery. Recent ...

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 ...

Michigan State University astrophysicists are closing in on one of space science’s biggest mysteries: where the galaxy’s most energetic particles come from. Their studies uncovered a pulsar wind ...

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 ...

Researchers have detected an extremely energetic cosmic ray from an unknown source in the universe. The detection of a cosmic ray with such high energy is "exceedingly rare" and the latest discovery, ...

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 ...
