For the first time ever, scientists using NASA\u2019s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino traveled 3.7 billion years at almost the speed of light before being detected on Earth. This is farther than any other neutrino whose origin scientists can identify.\u00a0<\/span><\/p>\n

High-energy neutrinos are hard-to-catch particles that scientists think are created by the most powerful events in the cosmos, such as galaxy mergers and material falling onto supermassive black holes. They travel at speeds just shy of the speed of light and rarely interact with other matter, allowing them to travel unimpeded across distances of billions of light-years.<\/span><\/p>\n\n\n\n

The neutrino was discovered by an international team of scientists using the National Science Foundation\u2019s IceCube Neutrino Observatory at the Amundsen\u2013Scott South Pole Station. Fermi found the source of the neutrino by tracing its path back to a blast of gamma-ray light from a distant supermassive black hole in the constellation Orion.<\/span><\/p>\n

\u201cAgain, Fermi has helped make another\u00a0giant leap in\u00a0a growing\u00a0field we call multimessenger astronomy,\u201d said Paul Hertz, director of the Astrophysics Division at NASA Headquarters in Washington. \u201cNeutrinos and gravitational waves deliver new kinds of information about the most extreme environments in the universe. But to best understand what they\u2019re telling us, we need to connect them to the \u2018messenger\u2019 astronomers know best\u2014light.\u201d\u00a0<\/span><\/p>\n

Scientists study neutrinos, as well as\u00a0cosmic rays<\/a>\u00a0and gamma rays, to understand what is going on in turbulent cosmic environments such as supernovas, black holes and stars. Neutrinos show the complex processes that occur inside the environment, and cosmic rays show the force and speed of violent activity. But, scientists rely on gamma rays, the most energetic form of light, to brightly flag what cosmic source is producing these neutrinos and cosmic rays.\u00a0<\/span><\/p>\n

\u201cThe most extreme cosmic explosions produce gravitational waves, and the most extreme cosmic accelerators produce high-energy neutrinos and cosmic rays,\u201d says Regina Caputo of NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland, the analysis coordinator for the Fermi Large Area Telescope Collaboration. \u201cThrough Fermi, gamma rays are providing a bridge to each of these new cosmic signals.\u201d<\/span><\/p>\n

The discovery is the subject of two papers published Thursday in the journal Science. The\u00a0source identification paper<\/a>\u00a0also includes important follow-up observations by the\u00a0Major Atmospheric Gamma Imaging Cherenkov Telescopes<\/a>\u00a0and additional data from NASA\u2019s\u00a0Neil Gehrels Swift Observatory<\/a>\u00a0and many other facilities.<\/span><\/p>\n
