These tiny subatomic particles<\/a> are central to understanding what goes on inside a supernova: because they zip out of the star\u2019s collapsing core and across space, they can provide information about any potentially new physics that occur under extreme conditions.<\/p>\n

At last month\u2019s Neutrino 2024<\/a> conference in Milan, Italy, Masayuki Harada, a physicist at the University of Tokyo, revealed<\/a> that the first hints of supernova neutrinos seem to be emerging from the cacophony of particles that the Super-Kamiokande detector collects every day from other sources, such as cosmic rays hitting the atmosphere and nuclear fusion in the Sun\u2019s core. The result \u201cindicates that we started observing a signal\u201d, says Masayuki Nakahata, a physicist at the University of Tokyo and spokesperson for the experiment, which is commonly referred to as Super-K. But Nakahata cautions that the supporting data \u2014 collected over 956 days of observation \u2014 are still very weak.<\/p>\n","protected":false},"excerpt":{"rendered":"
