银河系的中心
[img=627,570]http://www.eso.org/gallery/d/3123-2/phot-23a-02.jpg[/img][color=black]The centre of our Milky Way galaxy is located in the southern constellation Sagittarius (The Archer) and is "only" 26,000 light-years away. On high-resolution images, it is possible to discern thousands of individual stars within the central, one light-year wide region.[/color]
[color=black]Using the motions of these stars to probe the gravitational field, observations over the last decade have shown that a mass of about 3 million times that of the Sun is concentrated within a radius of only 10 light-days of the compact radio and X-ray source SgrA* ("Sagittarius A") at the centre of the star cluster.[/color]
[color=black]This means that SgrA* is the most likely counterpart of the black hole believed to exist at the centre of our Galaxy.

金山快译de一点都不准~~~~！！！ 我们银河系的中心位于南天的人马座，“仅有”26000光年远。在高解析度图像中，中心区域一光年的范围内就能目睹数千恒星。
利用这些恒星的运动来探查引力场，最近十年的观测表明在星群的中心大约有300万太阳质量的物质集中于半径仅十光天的范围内，致密的射电、X射线源也就是人马座A。这意味着人马座A极可能是我们星系中心黑洞的对应体 [quote]原帖由 [i]Rojer[/i] 于 2008-8-24 11:17 发表 [url=http://www.astronomy.com.cn/bbs/redirect.php?goto=findpost&pid=1003168&ptid=95846][img]http://www.astronomy.com.cn/bbs/images/common/back.gif[/img][/url]

谢谢你提供的译文.
直接看英文太累.一边看一边用金山词霸,只能勉强懂个大意.
