High-energy neutrinos are hard-to-catch particles that scientists think are created by the most powerful events in the cosmos, like galaxy mergers and material falling onto supermassive black holes. For the first time ever, scientists using our Fermi Gamma-ray Space Telescope have found the source of one of these zippy neutrinos from outside our galaxy!

Record-breaking neutrino tears through the Mediterranean Sea A neutrino with more energy than we've ever seen before was picked up by a cubic kilometre neutrino telescope (KM3NeT), a pair of detector arrays at the bottom of the Mediterranean Sea. The discovery of the 120 peta-electron volts neutrino has taken physicists by surprise, and it could be a first tantalising glimpse into some of the universe’s most cataclysmic events, such as the merging of supermassive black holes.
