A physics paper published September 8, 2026, in Physical Review Letters has used the world's largest cosmic-ray observatory in a way no experiment has tried before — measuring how much the number of ...

A reanalysis of cosmic gamma-ray measurements found no evidence of the tested departures from Lorentz invariance. The researchers tightened limits on specific photon-sector parameters by about a ...

Proton-oxygen collisions at the LHC reveal how extreme cosmic rays trigger particle showers when they slam into Earth’s atmosphere.

Francis Halzen Nobel Prize 2026: the Belgian-American physicist who built IceCube, a cubic-kilometer neutrino telescope under ...

Beijing, Mar 16 (PTI) After commissioning the world’s biggest telescope, China is now building one of the largest and most sensitive cosmic-ray facilities, costing about USD 180 million, official ...

This discovery suggests that there are many binary systems producing energetic ultraviolet radiation that have remained ...

Around 11 billion years ago, the Universe experienced a period of peak activity known as the ‘Cosmic noon’, characterised by ...

BEIJING, Sept. 21 (Xinhua) -- By combining data from a satellite and a ground-based observatory, Chinese scientists have discovered an X-ray trail stretching 42 light-years across the cosmos. This ...

Washington, April 1 (IANS) A mysterious flash of X-rays probably resulting from a “completely new type of cataclysmic event” in space has been discovered by NASA’s Chandra X-ray Observatory, a study ...

Artist’s impression of an ultra-high energy cosmic ray reaching Earth. New research suggests that some of the highest-energy cosmic rays may consist of atomic nuclei heavier than iron. The background ...

Recently detected gamma rays are best accounted for by relativistic protons accelerated by a millennia-old supernova. The cosmic-ray spectrum measured at facilities such as the Large High Altitude Air ...
