    This week, the National Science Foundation announced a groundbreaking discovery that provides answers to a question scientists have been asking for decades. A team at the NSF IceCube Neutrino Observatory at the Amundsen-Scott South Pole Station was able to trace the source of high-energy cosmic rays to their source: a blazar, which is a galaxy center that produces massive particle jets, powered by a supermassive black hole.

    Cosmic rays are energetic particles radiation that travel at nearly the speed of light and bombard the Earth. We know they originate outside our galaxy, but because they are deflected along the way, it's been impossible to trace their source. It's a puzzle scientists have been trying to solve since the discovery of cosmic rays in 1912.
