天文学家探测到来自古代星系的快速无线电爆炸 挑战了以前关于FRB来源的理论 Astronomers detect a fast radio burst from an ancient galaxy, challenging previous theories on FRB origins.

天文学家已经从一个古老的死星系中 探测到一个快速的无线电爆破 挑战了这样的理论 即FRBs只起源于年轻的恒星成形星系 Astronomers have detected a fast radio burst (FRB) from an ancient, dead galaxy, challenging the theory that FRBs originate only from young, star-forming galaxies. FRB 202402009A是加拿大氢气强度绘图实验(CHIME)在距地球20亿光年的11.3亿年星系外围发现的。 FRB 20240209A was found by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) near the outskirts of an 11.3-billion-year-old galaxy, 2 billion light-years from Earth. 这一发现表明FRB可能来自较古老的系统, This discovery suggests that FRBs could originate from older systems and raises new questions about their formation.
