Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO ...

For the first time, scientists have watched high‑energy cosmic rays at work deep inside a thick cloud of gas, not just at its outer surface. Using the High Altitude Water Cherenkov Observatory (HAWC), ...

A seven-hour gamma-ray burst, GRB 250702B, stuns astronomers and hints at powerful new cosmic engines still unknown to science.

Gamma-rays are the highest energy (the shortest wavelength) type of electromagnetic radiation. They are classified as a type of an ionising radiation; with respect to alpha and beta particles they ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

For the first time, scientists have caught lightning in the act of unleashing a powerful burst of gamma radiation known as a terrestrial gamma-ray flash (TGF). Researchers at the University of Osaka ...

Scientists use distant gamma ray bursts to prove that light maintains its constant speed, reinforcing Einstein's theory.

Using NASA's Fermi Gamma-ray Space Telescope, Chinese astronomers have observed a gamma-ray binary system known as PSR ...

The Australian Nuclear Science and Technology Organisation (ANSTO), will launch its new radiation detection technology, the CORIS360 Gamma Neutron ...
