An international research team in Antarctica has detected unusual radio signals that defy current scientific understanding. The signals were recorded by the Antarctic Impulsive Transient Antenna (ANITA) experiment, which uses a balloon-borne instrument to detect radio waves.
The signals appear to originate from beyond the horizon, contradicting expected patterns. These findings, published in Physical Review Letters, have left scientists without a clear explanation.
The team is now considering various hypotheses, including the possibility of an unknown radio propagation effect near the ice. Further research with the PUEO project, equipped with advanced technology, aims to provide more precise data and potentially solve the mystery.
