NASA’s ANITA Experiment Picked Up Strange Signals Beneath Antarctic Ice That Traveled Through Thousands of Kilometers of Rock

A decade after their detection, strange radio pulses emerging from beneath Antarctica continue to puzzle scientists. New research has ruled out some of the most exciting explanations, but the true origin of these signals remains unknown. The signals were first captured between 2016 and 2018 by NASA’s ANITA experiment, a balloon-borne antenna designed to detect radio waves produced by high-energy cosmic particles. Instead of observing expected re…
