[New Image of Black Hole Revealed]

Two years after producing the first-ever image of a black hole, an international team of researchers has released an updated image that shows magnetic fields surrounding it -- a development they say brings them one step closer to understanding the M87 galaxy's ability to "launch energetic jets from its core." 

Using the same data from the first image, scientists analyzed polarized-light around the black hole -- light whose waves are vibrating in one direction only. By looking at how the light became polarized, astronomers can learn about the material that produced it. To study the center of M87, scientists around the world used a global network of eight telescopes. Scientists from Shanghai Astronomical Observatory of Chinese Academy of Sciences also participated in the research.

偏振测量，帮助天文学家绘制出存在于黑洞边缘的磁力线，这也是理解黑洞利用磁场"吞噬"物质并发出能量巨大的喷流的关键。

为观测M87星系的中心，世界各地的科学家把全球各处八台射电望远镜连接起来，创建了一个虚拟口径等效于地球直径的望远镜EHT。由中科院上海天文台科研人员领衔的我国团队深度参与了这项研究。
