Astronomers unveil first image of black hole at the heart of the Milky Way.天文学家揭开银河系中心黑洞的第一张照片
部分节选:
The first image of the supermassive black hole at the heart of the Milky Way was unveiled on Thursday thanks to the efforts of astronomers from around the world, including 17 from China.
The new image was captured by researchers from the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes.这幅新图像是由事件视界望远镜(EHT)合作组织的研究人员利用全球射电望远镜网络的观测结果拍摄的。
In 2019, the EHT Collaboration released the first direct image of a black hole of Messier 87, a massive galaxy in the Virgo cluster.2019年,EHT合作组织发布了第一张Messier 87黑洞的直接图像,这是室女座星系团中的一个大质量星系。
The image of this object known as Sagittarius A-star, often referred to as Sgr A*, shows the telltale sign of a black hole, as did the earlier one in the Messier 87 galaxy: a bright ring of superhot glowing material circling a dark center so dense and bottomless that not even light can escape. The way the light bends around the dark center, known as the event horizon, shows the object's powerful gravity which is 4 million times that of our sun, according to a report from The Harvard Gazette.这个被称为人马座A星(通常被称为Sgr A*)的物体的图像显示了黑洞的迹象,就像梅西耶87星系中的早期黑洞一样:一个明亮的超高温发光物质环围绕着一个黑暗的中心,密度如此之大,深不见底,甚至连光都无法逃脱。根据《哈佛公报》的一份报告,光线围绕黑暗中心弯曲的方式,即所谓的事件视界,显示了该物体强大的引力,是我们太阳的400万倍。
The new picture provides the first direct visual evidence that the giant, lurking 27,000 light-years away at the center of Earth's galaxy is, in fact a supermassive black hole. It also bolsters theories of where these cosmic monsters exist and may help to explain how galaxies are formed, read the report.这张新照片提供了第一个直接的视觉证据,证明潜伏在27000光年外地球星系中心的巨大黑洞实际上是一个超大质量黑洞。报告称,这也支持了这些宇宙怪物存在于何处的理论,并可能有助于解释星系是如何形成的。
