Mysterious New Signals Detected by SETI: Unlocking the Strange Puzzle of Fast Radio Bursts

This work proves that new telescopes with unique capabilities, like the ATA, can provide a new angle on outstanding mysteries in FRB science.

A team of SETI Institute scientists have unveiled new insights into a cosmic mystery known as Fast Radio Bursts (FRBs). The discovery and detailed observation of the repeating FRB 20220912A, made at the SETI Institute’s upgraded Allen Telescope Array (ATA), shed light on the nature of these space signals.

FRBs are brief, intense flashes of radio waves from deep space. While most happen only once, some “repeaters” send out signals more than once, adding to the intrigue of understanding their origin. Over 541 hours of observation, researchers detected 35 FRBs from repeater FRB 20220912A. The observations, made using the ATA, covered a wide radio frequency range and revealed fascinating patterns. All 35 FRBs were found in the lower part of the frequency spectrum, each with its unique energy signature.
