(CNN) — Scientists are trying to solve a decade-long mystery by determining the identity of anomalous signals detected from below ice in Antarctica. The strange radio waves emerged during a search for ...

Physicists have spent decades trying to explain puzzling radio bursts and other odd signals that seem to arrive from deep space with no obvious source. Some technologists now wonder whether the same ...

Anomalous radio signals detected in Antarctica by the ANITA experiment were coming upward from Earth rather than down from the sky. Researchers used digital and mathematical simulations to test ...
