Astronomers detect subatomic particles from a gigantic black hole in a nearby galaxy

Among the many cosmic rays of the universe that pass through the Earth unseen, scientists have spotted astrophysical neutrinos that emanate from a nearby galaxy. Observed by an international team of scientists for the first time, the neutrinos were detected by the one billion ton IceCube Neutrino Observatory, that is situated 1.5-2.5 kilometres below the surface at the South Pole. A new study, published in the journal Science, reports the detection of high-energy astrophysical neutrinos that emerged from a galaxy called NGC 1068 located in the constellation Cetus. Due to the highly inert nature of the galaxy, neutrinos emerging therefrom give scientists a chance to study the surroundings of supermassive black holes in a more detailed manner. The jump from detecting of a dozen neutrinos from TXS 0506+056 to 80 neutrinos from NGC 1086 shows that the enhanced techniques and updated detector calibration of the IceCube Observatory may open new doors in the study of neutrino astronomy, which has been envisioned by scientists for close to six decades.
