A cosmic explosion that lasted seven hours: this is the unusual spectacle recently observed by astronomers. Named GRB 250702B ...

The most powerful cosmic-ray electrons and positrons ever detected slamming into Earth's atmosphere carry energies so high they can only have come from relatively close by, new research has revealed.

Electrons released when cosmic rays strike water-ice can provide energy for microbes and facilitate the formation of complex organic molecules.

Scientists have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the origins ...

PD Dr Philipp Girichidis at Heidelberg University’s Centre for Astronomy provide insights into our place in the Milky Way and ...

The investigation of cosmic rays and their potential connection with dark matter occupies a central role in contemporary astrophysics. Recent experimental and theoretical advances have refined our ...

An illustration of a young solar system immersed in high-energy cosmic rays from a nearby supernova. Unlike considering only direct injection of supernova ejecta, this process naturally explains key ...

(a)The UHE gamma-ray emission is clearly observed from the W51 complex, which hosts the supernova remnant W51C and star forming region W51B. (b) The “bending” feature around tens TeV indicates the ...

Ben may have been right way back when Stan Lee and Jack Kirby created him and the rest of the Fantastic Four 64 years ago, but we know a heck of a lot more about cosmic rays today. Back then, Grimm, ...
