Swift Links Neutrino to Star destroying Black Hole

For only the second time, astronomers have linked an elusive particle called a highenergy neutrino to an object outside our galaxy. Using ground and spacebased facilities, including NASAs Neil Gehrels Swift Observatory, they traced the neutrino to a black hole tearing apart a star, a rare cataclysmic occurrence called a tidal disruption event.

Astrophysicists are particularly interested in highenergy neutrinos, which have energies up to 1, 000 times greater than those produced by the most powerful particle colliders on Earth. They think the most extreme events in the universe, like violent galactic outbursts, accelerate particles to nearly the speed of light. Those particles then collide with light or other particles to generate highenergy neutrinos. The first confirme
