- In 1933 Zwicky estimated the total amount of mass in a cluster of galaxies, the Coma Cluster, based on the motions of the galaxies near the edge of the cluster. 在1933年Zwicky估计一星系团Coma星团总物质量在星系运动的基础上接近星团的边缘。
- Caption:: NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe. 后发座星系团位于银河系的北端，由于没有尘埃与气体的阻隔，所以在地球上能清楚看见。

- Explanation: Across the heart of the Virgo Cluster of Galaxies lies a striking string of galaxies known as Markarian's Chain. 说明：一条引人注目的星系长链横穿室女座星系团的中心，我们称之为“马卡良星系链”。
- To start, most of the yellowish objects in the above image from the Hubble Space Telescope are galactic members of a massive cluster of galaxies known as Abell 2667. 在上面这张由哈勃太空望远镜拍摄到的影像中，大多数微黄色的天体就是我们所知道阿贝耳2667星系团内巨大的成员。
- For earth-based astronomers, NGC 1350 is seen on the outskirts of the Fornax cluster of galaxies, but its estimated distance suggests that it is not itself a cluster member. 对于地球上的天文学家来说，NGC 1350看起来好像位于天炉星系团的边界上，不过估计距离暗示它不是星团成员。
- A new observation of gravitationally magnified faint galaxies far in the distance behind a massive cluster of galaxies is shedding new dark on the subject. 针对大质量星系团后方遥远星系进行了一次新的重力透镜效应观测，结果发现了新的暗物质。
- On larger scales, analogous halos are thought to keep clusters of galaxies bound together. 在更大的尺度上，有人相信，由于存在著类似的晕体，星系团才凝聚在一起。
- A cluster of stars smaller than a constellation. 星群，星座比星座小的一簇星星
- A supercluster is an aggregate of several clusters of galaxies, extending over about 10 Mpc. 超星系团是几个银河群集合体,伸展大约10Mpc。
- If the lens is not a single galaxy but an entire cluster of galaxies, the image can be a kaleidoscope of strongly distorted arcs and arclets. 如果透镜不是单一星系，而是一整个星系团，影像就可能像万花筒，是一些极度扭曲的弧形与小弧形。
