Deep under Antarctic ice, a long-predicted cosmic whisper finally breaks through in 13 strange bursts
Summary
Phys.org reports the detection of Askaryan radiation in Antarctic ice from high-energy cosmic rays, validating a predicted phenomenon and enabling future ultrahigh-energy neutrino searches. Thirteen events over a 208-day campaign yielded a 5.1 sigma significance, confirming the technique used by the Askaryan Radio Array and shaping neutrino astronomy.
