Add Yahoo as a preferred source to see more of our stories on Google. A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of an ...
Combination of a Hubble Space Telescope image of SN 1987A and the compact argon source. The faint blue source in the centre is the emission from the compact source detected with the JWST/NIRSpec ...
Stellar black holes form from the collapse of massive stars at the end of their lives, typically weighing 3 to 50 times the mass of the sun. When a star runs out of fuel, it explodes in a supernova, ...
How is lightning initiated in thunderclouds? This is difficult to answer – how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, ...
Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through ...
The last gasp of a primordial black hole may be the source of the highest-energy “ghost particle” detected to date, a new MIT study proposes. In a paper appearing today in Physical Review Letters, MIT ...

A single subatomic particle that hit Earth in 2023 carried roughly 100,000 times more energy than anything humanity has ever produced in a particle collider. It was a neutrino, one of nature’s most ...
