Strange Radio Signals from Antarctic Ice Leave Scientists Baffled

Scientists have detected mysterious radio signals coming from deep within the Antarctic ice, and they don’t know what’s causing them. Researchers at Penn State used a special cosmic particle detector—a device that picks up tiny particles from space—to find these unusual signals.

According to a press release, these signals “defy the current understanding of particle physics,” meaning they don’t match what scientists currently know about how particles behave.

The detector, which is part of a project called the Antarctic Impulsive Transient Antenna (ANITA), is an unusual setup—it’s actually hanging from a cluster of high-altitude balloons.

Normally, ANITA detects particles that come from space and bounce off the Earth’s surface. But this time, the signals seemed to be coming from below the ice, which was unexpected and confusing....<<<Read More>>>...
