"天关"卫星捕获EP250702a事件艺术想象图。（图片来源：国家天文台） 2025年7月2日，搭载于卫星上的宽视场X射线望远镜WXT（昵称"万星瞳"）在例行巡天观测中，发现一例突然出现的，存在剧烈光变的暂 现源。 "这种现象， 非常类似于罕见的带喷流的黑洞瓦解恒星事件。 "国家天文台副研究员张文达解释说。 据新华社，记者2月9日从中国科学院国家天文台获悉， 我国"天关"卫星在巡天中，捕捉到一个异常明亮且急剧变化的X射线源， 随后全球多台望远 镜将"镜头"对准此处，展开了一场跨波段的联合观测。 这个被编号为EP250702a（亦因其伽马射线耀发被称为GRB 250702B）的事件，其亮度变化、辐射节奏与光谱特征均与以往任何已知的 爆发显著不同。在最新一期《科学通报》的封面文章中，科研团队提出一个突破性解释： 这很可能是一个中等质量黑洞撕裂并吞噬一颗白 矮星的过程。 这也是人类首次捕捉到如此极端的黑洞"进食"现场。 基于这些观测事实，"天关"科学团队提出了一个物理上自洽的图景：一个中等质量黑洞，撕裂并吞噬了一颗白矮星。 下载财联社APP获取更多资讯 准确 快速 权威 专业 7x24h电报 头条新闻 VIP资讯 ...
