Story summary

Scientists from The Pennsylvania State University (Penn State) and the Pierre Auger Observatory study unusual radio signals detected by NASA's Antarctic Impulsive Transient Antenna (ANITA) in Antarctica during 2016–2018.
The signals originate from below the ice and challenge physics models.
Researchers say the signals are likely not neutrinos, as they cannot be traced to known sources.
The team is developing PUEO to enhance sensitivity and clarify these anomalies.
