Physicists can't explain mysterious radio wave emissions in Antarctica

Breakthroughs, discoveries, and DIY tips sent every weekday. 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 with no charge that also possess the smallest known subatomic mass. But according to their recent report, ANITA has repeatedly picked up some truly weird signals that defy explanation.
