安朵美达的一颗巨型恒星在亮光后消失 可能直接坠入黑洞 却没有超新星 提供了罕见的黑洞形成证据 A massive star in Andromeda vanished after brightening, possibly collapsing directly into a black hole without a supernova, offering rare evidence of black hole formation.

安朵美达银河系的一颗恒星在2015年突然亮起之后消失,随后迅速消失,只留下微弱的红外信号。 A star in the Andromeda Galaxy vanished after suddenly brightening around 2015, then fading rapidly, leaving only a faint infrared signal. 研究人员使用15年NEOWISE数据, 认为它可能直接塌成一个黑洞而没有超新星, Researchers, using 15 years of NEOWISE data, believe it may have collapsed directly into a black hole without a supernova, a rare event predicted by theory but rarely observed. 消失与"失败的超新星"的模型一致 巨大的恒星静悄悄地死去 The disappearance aligns with models of a "failed supernova," where a massive star dies quietly. 虽然有些专家提出其他解释, 如尘埃或星体合并, 但关键测试将是剩余恒星是否继续消退, 以证实恒星最终死亡。 While some experts suggest alternative explanations like dust or merging stars, the key test will be whether the remnant continues to fade, confirming the star’s final death. 此次活动为观察黑洞形成提供了最好的机会之一。 This event offers one of the best chances yet to observe black hole formation.
