India, June 18 -- Scientists have recently detected a pattern of strange signals in the sky above Antarctica. It defies current physics models and could represent a new particle, scientists told Space.com.

Discovered by the Antarctic Impulsive Transient Antenna (ANITA) experiment, the signal pulses were found at about 40 kilometers above the surface of the Earth.

According to a report by The Pennsylvania State University(PSU), Antarctic Impulsive Transient Antenna (ANITA) comprises ranging instruments that are flown on balloons. Designed in a specialized manner to detect radio waves or subatomic particles from cosmic rays that hit the atmosphere, ANITA experiment balloons hover high above Antarctica skies.

"We use radio detectors to tr...
