巨引源

“巨引源”所在天空区域的哈勃空间望远镜的图像。

巨引源（英语：Great Attractor）指的是位于拉尼亚凯亚超星系团中心的长蛇-半人马座超星系团附近的引力异常处，一个相当于数万个银河系质量的引力中心，距离地球1.5亿至2.5亿光年。大约几亿光年外的包括本星系群和室女座星系团成员在内数百万个星系都受到它的影响。

所有这些星系都发生红移，依据哈伯定律显示它们之间以及地球都在相互远离，红移量和哈勃定律预测值的差异（即本动速度）揭示了巨引源的存在。它们向巨引源方向的本动速度从+700km/s到-700km/s间不等。

Hubble Telescope image of the region of the sky where the Great Attractor is located

The Great Attractor is a gravitational anomaly in intergalactic space within the vicinity of the Hydra-Centaurus Supercluster at the centre of the Laniakea Supercluster that reveals the existence of a localised concentration of mass tens of thousands of times more massive than the Milky Way. This mass is observable by its effect on the motion of galaxies and their associated clusters over a region hundreds of millions of light-years across. The Great Attractor is moving towards the Shapley Supercluster.
