ANITA, a scientific instrument, detected unusual signals from high-energy neutrinos, as reported in the Astrophysical Journal. Suspended by a helium balloon over Antarctica, ANITA is designed to detect neutrinos that hit the Antarctic floor. The detected signals suggest neutrinos behaving abnormally, possibly traveling through Earth, which could indicate new physics beyond the standard model or a systematic error.
