IceCube reports first evidence of a source of high-energy cosmic neutrinos

Scientists at IceCube observatory and collaborators identify what deem to be a source of very high energy neutrinos and, thus, of cosmic rays. 

Blazar TXS 0506+056 was first singled out as the source. A blazar is a giant elliptical galaxy with a massive, rapidly spinning black hole at its core, which emits twin jets of light and elementary particles.
