On Sept. 22, 2017, the IceCube Neutrino Observatory at the South Pole, represented in this illustration by strings of sensors under the ice, detected a high-energy neutrino that appeared to come from deep space. NASA's Fermi Gamma-ray Space Telescope (center left) pinpointed the source as a supermassive black hole in a galaxy about 4 billion light-years away. It is the first high-energy neutrino source identified from outside our galaxy. Credits: NASA/Fermi and Aurore Simonnet, Sonoma State University
