银河系核心的新发现：人马座 A* 的新发现

最近对位于银河系中心的超大质量黑洞人马座 A* 的探索取得了引人注目的新发现。

Astronomers have made a groundbreaking discovery at the heart of our Milky Way galaxy, where a supermassive black hole named Sagittarius A lurks, approximately 27,000 light years away from Earth. This black hole spans an astonishing 23.5 million kilometers in diameter.

天文学家在银河系中心取得了突破性发现，那里潜伏着一个名为人马座 A 的超大质量黑洞，距离地球约 27,000 光年。这个黑洞的直径达到惊人的2350万公里。

Now, a team of astronomers, led by Florian Peißker from the University of Cologne, Germany, have identified a binary star system orbiting this colossal black hole. Their findings are published in the journal Nature Communications.

现在，由德国科隆大学弗洛里安·佩克 (Florian Peißker) 领导的天文学家团队发现了一个围绕这个巨大黑洞运行的双星系统。他们的研究结果发表在《自然通讯》杂志上。

Binary star systems consist of two stars that orbit around a common center. This arrangement is not typical for our Sun, which exists alone, avoiding the chaotic gravitational forces that could arise from additional stars nearby.

双星系统由两颗围绕共同中心运行的恒星组成。这种排列对于我们的太阳来说并不典型，太阳单独存在，避免了附近其他恒星可能产生的混乱引力。

Despite previous predictions, no binary star systems had been detected near supermassive black holes until now. The research team utilized the European Southern Observatory’s Very Large Telescope to capture the peculiar movement of starlight, allowing them to identify the binary stars through a method known as the Doppler effect.

尽管之前有预测，但迄今为止尚未在超大质量黑洞附近检测到双星系统。研究小组利用欧洲南方天文台的甚大望远镜捕捉到星光的奇特运动，使他们能够通过一种称为多普勒效应的方法来识别双星。

The revelation that these stars are approximately 2.7 million years old provides critical information about the black hole's gravitational influence and its capacity to disrupt nearby celestial bodies. As we delve deeper into the mysteries of black holes, each discovery brings forth a greater understanding of our universe.

这些恒星大约有 270 万年历史的消息提供了有关黑洞引力影响及其扰乱附近天体能力的关键信息。随着我们深入研究黑洞的奥秘，每一项发现都会让我们对宇宙有更深入的了解。
