[1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2018 July 16 [2] Neutrino Associated with Distant Blazar Jet Illustration Credit: DESY [3] , Science Communication Lab [4] Explanation: With equipment frozen deep into ice beneath Earth's South Pole, humanity appears to have discovered a neutrino [5] from far across the universe. If confirmed, this would mark the first clear detection of cosmologically-distant neutrinos [6] and the dawn of an observed association [7] between energetic neutrinos and cosmic rays [8] created by powerful jets emanating from blazing quasars (blazars [9] ). Once the Antarctican IceCube [10] detector measured an energetic neutrino in 2017 September, many of humanity's premier observatories sprang into action to try to identify a counterpart in light [11] . And they did. An erupting counterpart was pinpointed by high energy observatories including AGILE [12] , Fermi [13] , HAWC [14] , H.E.S.S. [15] , INTEGRAL [16] , NuSTAR [17] , Swift [18] , and VERITAS [19] , which found that gamma-ray blazar TXS 0506+056 [20] was in the right direction and with gamma-rays [21] from a flare arriving [22] nearly coincidental in time with the neutrino. Even though this and other position and time coincidences [23] are statistically strong, astronomers will await other similar neutrino - blazar light associations to be absolutely sure. Pictured here [24] is an artist's drawing of a particle jet [25] emanating from [26] a black hole at the center of a blazar.
