US EditionScientists Perplexed by Strange Signals From Beneath Antarctica
- On June 16, 2025, an array of balloon-borne detectors operating over Antarctica recorded unusual radio signals originating from approximately 30 degrees below the horizon.
- The signals pose a challenge to existing particle physics models because they appear to have traveled through extensive layers of rock and ice, which under normal circumstances would have prevented their detection by absorbing the radio waves.
- ANITA is a balloon-based instrument array flying at altitudes between 37 and 40 kilometers above the Antarctic ice, aimed at capturing radio signals produced when cosmic rays interact with the Earth's atmosphere across an immense volume of ice exceeding one million cubic kilometers.
- The research team shared their unexpected findings in Physical Review Letters, and Stephanie Wissel suggested that there might be an unusual radio wave behavior happening close to the ice surface and near the horizon that is not yet fully understood.
- Researchers are developing the larger, more sensitive PUEO detector, originally planned for 2024 launch, to detect more anomalies and possibly clarify their origin or find neutrinos.

‘Edge of the observable universe’: Scientists detect mysterious radio waves coming from beneath Antarctica’s ice
from WND: ‘This is the double-edged sword problem. If we detect them, it means they have traveled all this way without interacting with anything else’ A group of researchers in Antarctica have found strange radio waves coming from below the ice. According to the results published in the Physical Review Letters, the mysterious radio waves […]
Physicists can't explain mysterious radio wave emissions in Antarctica
For nearly two decades, balloons carrying highly sensitive atmospheric instruments have drifted more than 25 miles above one of the world’s most remote regions. The floating array is the Antarctic Impulsive Transient Antenna (ANITA) experiment, a project overseen by an international group of researchers tasked with measuring some of the universe’s oldest and hardest-to-detect cosmic rays. Specifically, the team is hunting for neutrinos—particles…
