研究人员确定了神秘无线电信号的来源是北斗七星中的一对恒星。 Researchers identify source of mysterious radio signals as a pair of stars in the Big Dipper.

科学家们追踪了十多年来定期探测到的神秘无线电信号，指向北斗七星中的一对轨道恒星：一颗红矮星和一颗白矮星。 Scientists have traced mysterious radio signals, detected periodically over a decade, to a pair of orbiting stars in the Big Dipper: a red dwarf and a white dwarf. 这些信号持续数秒到数分钟，与快速射电暴 （FRB） 相似但不同。 These signals, lasting seconds to minutes, are similar but distinct from fast radio bursts (FRBs). 《自然天文学》杂志上的这一发现揭示了这些信号的新来源，这是以前无法解释的，并提供了对天文现象的见解。 This discovery in the journal Nature Astronomy reveals a new source of these signals, previously unexplained, and offers insights into astronomical phenomena.
