MIT Deciphers Mysterious FRB 20221022A
In a groundbreaking 2024 study, MIT researchers pinpointed the origin of FRB 20221022A to a magnetar’s turbulent magnetosphere, located 200 million light-years away. Utilizing scintillation techniques, they mapped the burst to within 10,000 kilometers of the neutron star, debunking prior theories of distant shockwave sources. Published in Nature, this discovery not only settles a cosmic mystery but also sparks curiosity about the diverse origins of fast radio bursts. Who knew magnetars could be such chatterboxes?
