Mechanism explains how the most energetic form of light can be produced in areas dominated by bright, young stars In 2002, when astronomers first detected cosmic gamma rays — the most energetic form ...

While the San Francisco 49ers and the Baltimore Ravens were butting heads and other body parts a couple of Sundays ago, they were simultaneously taking a whole different type of pounding, though they ...

Ever since French physicist Pierre Auger proposed in 1939 that cosmic rays must carry incredible amounts of energy, scientists have puzzled over what could be producing these powerful clusters of ...

The highest-energy cosmic rays come from subatomic interactions within star clusters, not supernovae, say Michigan Tech physicists and collaborators. For decades, researchers assumed the cosmic rays ...

The study of cosmic rays, high-energy particles originating from extraterrestrial sources, has significantly progressed with the advent of both ground-based and space-borne detection techniques.

An incredibly fast-moving particle from space recently arrived on Earth, and physicists are rushing to figure out what it is and where it came from. Called the Amaterasu particle, after the Shinto ...

WASHINGTON – Researchers studying global warming have often been confounded by the differences between observed increases in surface-level temperatures and unchanging low-atmosphere temperatures.
