The collision created the first observed instance of a single source emitting ripples in space-time, known as gravitational waves, as well as light, which was released in the form of a two-second gamma ray burst.
通过这次合并,科学家首次观测到太空中单源发射的引力波,并观测到了以两秒钟的伽马射线暴形式释放出的可见光。
It is being hailed as the first known instance of multi-messenger astrophysics: one source in the universe emitting two kinds of waves, gravitational and electromagnetic.
这预示着天体物理学首次进入多信使阶段:宇宙中的同一来源发射出两种形式的波,引力波和电磁波。
你戴的金戒指来自中子星碰撞?
中国紫金山天文台副研究员金志平参与的国际团队,通过对此次引力波光学信号的观测和光谱分析,首次提供确凿证据证实,中子星合并是宇宙中金银等元素的主要起源。金志平说:“这就是宇宙中的‘巨型黄金制造厂’。”
These images revealed a radioactive soup giving birth to unfathomable amounts of platinum, gold, and silver — not to mention elements like the iodine found in our bodies, the uranium in nuclear weapons, and the bismuth in Pepto-Bismol — while shooting those materials deep into space.
观测图像显示出了两个中子星的放射性碰撞场景,而这也产生了数量庞大的铂、金和银,以及我们身体中的碘、核武器中的铀、可以减轻肠胃不适的铋。中子星合并将这些物质四散进宇宙深处。
