天文学家在一天内探测到三次异常长的伽马射线暴 信号是一场神秘的宇宙事件 Astronomers detected three unusually long gamma-ray bursts in one day, signaling a mysterious cosmic event.

2024年7月,天文学家在24小时内发现了一系列罕见的三次重复的伽马射线暴,这与过去50多年来观察到的情况不同。 In July 2024, astronomers detected a rare series of three repeating gamma-ray bursts within 24 hours—unlike any previously observed in over 50 years. 与通常持续毫秒至分钟的暴风雨不同,这些暴风雨持续了100至1000倍以上。 Unlike typical bursts lasting milliseconds to minutes, these lasted 100 to 1,000 times longer. 美国航天局的Fermi Gamma-射线空间望远镜首次发现,从爱因斯坦探测器、Swift天文台和地面望远镜得到的后续数据证实了远在数十亿光年之外的银河系中的这一来源。 First spotted by NASA’s Fermi Gamma-ray Space Telescope, follow-up data from the Einstein Probe, Swift Observatory, and ground-based telescopes confirmed the source in a distant galaxy billions of light-years away. 原因仍然不明,主要理论包括超新星或白矮星被稀有的中间质量黑洞撕裂。 The cause remains unknown, with leading theories including a prolonged supernova or a white dwarf torn apart by a rare intermediate-mass black hole. 利用James Webb空间望远镜正在进行的研究旨在查明其起源,并评估这类事件是极为罕见的还是被忽视的宇宙现象的一部分。 Ongoing studies using the James Webb Space Telescope aim to uncover the origin and assess whether such events are extremely rare or part of an overlooked cosmic phenomenon.
