Scientists (科学家) showed the first image of the black hole (洞) which is at the center of our galaxy (星系) .
科学家们展示了位于银河系中心的黑洞的第一张图像。
The image doesn’t actually(实际上) show the black hole . The black hole’s gravity (重力) is so strong(强烈的) that we can see only a bright (明亮)ring (环状) around it. The ring is the material(物质), gas (气体) , and dust (灰尘) which the black 
hole is swallowing (吞噬) .
这张图片实际上并没有显示黑洞。黑洞的引力很强，我们只能看到它周围有一个明亮的环。环是黑洞吞噬的物质、气体和尘埃。
The black hole is four million times(倍) the mass (质量) of our Sun . The ring around it is about 60 million kilometers(千克), which is about the same as(与…一样) Mercury’s(水星) orbit (围绕…运动) around the Sun .
黑洞的质量是太阳的四百万倍。它周围的环长约6000万公里，与水星围绕太阳的轨道大致相同。
To take(拍照) the image, scientists (科学家) used eight different telescopes (望远镜) around 
the world. They believe the image will help them understand gravity and how materials behave (行为) in the black hole .
为了拍摄这张照片，科学家们在世界各地使用了八台不同的望远镜。他们相信这张图像将帮助他们理解引力以及黑洞中物质的行为。
