马克斯·普朗克射电天文研究所的研究团队发现，位于星系Mrk 501中心的两个超大质量黑洞正在螺旋靠近，预计在未来100年内发生碰撞1。研究人员通过观测到的第二条粒子喷流确认了第二个黑洞的存在1。
这两个黑洞的质量范围为太阳质量的1亿倍至10亿倍1。根据长达约23年的观测数据，这两个天体每121天完成一次轨道运行，彼此间的距离仅为日地距离的250至540倍1。2022年6月，研究人员观测到了不寻常的爱因斯坦环现象1。研究团队综合了多个频率的射电观测数据进行分析1，相关研究已发表在《皇家天文学会月刊》2026年第548卷第4期1。
Astronomers have discovered two supermassive black holes locked in a spiral orbit at the center of galaxy Mrk 501, with a potential collision occurring within the next 100 years.1 The research team, led by Silke Britzen at the Max Planck Institute for Radio Astronomy, confirmed the existence of the second black hole by detecting a second particle jet through observations spanning approximately 23 years across multiple radio frequencies.1 The two black holes complete one orbital cycle every 121 days and maintain a separation of between 250 and 540 times the Earth-Sun distance.1
The discovery was bolstered by an unusual Einstein ring phenomenon observed in June 2022.1 Each black hole is estimated to possess a mass between 100 million and 1 billion times that of our Sun.1 The findings have been published in the Monthly Notices of the Royal Astronomical Society, Volume 548, Issue 4, in 2026.1
