The IceCube Neutrino Observatory at the South Pole is the world's largest neutrino detector, designed to solve the mystery of cosmic ray origins by detecting high-energy neutrinos. Unlike cosmic rays, neutrinos travel in straight paths, making them easier to trace back to their sources. On September 22, 2017, IceCube detected a neutrino, leading to a global effort to identify its source. Multi-messenger astrophysics, involving various telescopes, confirmed a blazar as the source. This discovery links blazars to cosmic ray production, providing insights into powerful cosmic events.
