銀河系核心的新發現：人馬座 A* 的新發現

最近對位於銀河系中心的超大質量黑洞人馬座 A* 的探索取得了引人注目的新發現。

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.

天文學家在銀河系中心取得了突破性發現，那裡潛伏著一個名為人馬座 A 的超大質量黑洞，距離地球約 27,000 光年。這個黑洞的直徑達到驚人的2350萬公里。

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.

現在，由德國科隆大學弗洛里安·佩克 (Florian Peißker) 領導的天文學家團隊發現了一個圍繞這個巨大黑洞運行的雙星系統。他們的研究結果發表在《自然通訊》期刊。

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.

雙星系統由兩顆圍繞共同中心運行的恆星組成。這種排列對於我們的太陽來說並不典型，太陽單獨存在，避免了附近其他恆星可能產生的混亂引力。

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.

儘管先前有預測，但迄今尚未在超大質量黑洞附近偵測到雙星系統。研究小組利用歐洲南方天文台的甚大望遠鏡捕捉到星光的奇特運動，使他們能夠透過一種稱為多普勒效應的方法來識別雙星。

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.

這些恆星大約有 270 萬年歷史的消息提供了有關黑洞引力影響及其擾亂附近天體能力的關鍵資訊。隨著我們深入研究黑洞的奧秘，每項發現都會讓我們對宇宙有更深入的了解。
