"Unveiling the Enigma: Astronomers Discover New Clues to Mysterious Fast Radio Bursts"

Astronomers have discovered a new quirk in a repeating fast radio burst (FRB) called FRB 20220912A. The burst, detected using the Allen Telescope Array, exhibited a noticeable drop in the center frequency, resembling a celestial slide whistle. The researchers were unable to find a pattern in the timings between each burst, suggesting that FRBs can be unpredictable. The study provides valuable clues to understanding the source of FRBs, which may originate from extreme objects such as magnetars, but existing models cannot explain all observed properties. The findings highlight the importance of new telescopes like the ATA in unraveling the mysteries of FRBs.
