A balloon drifting 37 kilometers above Antarctica once caught a whisper from the ice that should never have been heard. In 2016, NASA’s Antarctic Impulsive Transient Antenna (ANITA) detected radio ...

Unusual radio signals from beneath Antarctica’s ice continue to defy explanation. Several years ago, scientists using a ...

In 2016, a NASA experiment detected something completely unexpected above Antarctica. A balloon-based antenna picked up radio ...

A balloon-borne experiment now flying high above Antarctica is headed for an unprecedented second loop around the South Pole in search of the origin of cosmic rays, atomic particles that travel ...

(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 ...

Scientists are baffled by weird signals detected beneath Antarctica. A cosmic particle detector designed to pick up rays from space instead recorded a series of bizarre signals from under the ice.

It’s day 42 in Antarctica. The group has survived temperatures ranging from 35 degrees Fahrenheit to just below zero. They have learned to build snow walls, work as a team to navigate through ...

Nearly two decades ago, an experiment floating high above Antarctica caught a weird signal. The balloon-borne suite of instruments recorded a similar event in 2014, and scientists have been scratching ...
