Astronomers with The LHAASO Collaboration have found that last year's GRB 221009A gamma-ray burst, subsequently nicknamed the Brightest of All Time (BOAT), carried with it 13 teraelectronvolts of energy. In their study, reported ...
(PhysOrg.com) -- To produce "green" fuels, some scientists are looking for a little help from above. Sunlight is the key ingredient in photocatalytic water splitting, a process that breaks down water into oxygen and, most ...
