In 2013, the IceCube neutrino telescope detected dozens of high-energy neutrinos. Now, reports Astronomy magazine, researchers “have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of [those] 2013 observations confirming the existence of cosmic neutrinos.” According to the report, Albrecht Karle from UW-Madison notes that while the neutrino-induced tracks recorded by the IceCube detector have a good pointing resolution, within less than a degree, the IceCube team has not observed a significant number of neutrinos emanating from any single source. … “The plane of the galaxy is where the stars are. It is where cosmic rays are accelerated, so you would expect to see more sources there. But the highest-energy neutrinos we’ve observed come from random directions,” said Karle. “It is sound confirmation that the discovery of cosmic neutrinos from beyond our galaxy is real.”
