Astronomers Trace Origin of Ghost Particle for the Very First Time

A neutrino detected in Antarctica has been traced back to a blazar in the constellation Orion , providing an explanation high-energy cosmic rays that have baffled astronomers for decades. "This whole project is an interesting mix of scientists whose work together began through things like the IceCube Alerts and Astronomer's Telegrams, and progressed to an impressive collaboration of facilities working together on one paper ", said Sivakoff.
