TXS 0506+056

TXS 0506+056 is a blazar: first known source of a high-energy neutrino in the constellation Orion, about 4 billion light-years (z = 0.337) from Earth.

In September 2017 the IceCube detector at the South Pole caught a high-energy neutrino from this direction while the blazar was flaring in gamma rays: the first known source of a high-energy cosmic neutrino.
