在极遥远的未来，居住于此超级星团中的天文学家将如何描述宇宙的历史呢？
What will astronomers of the far future, living in this supercluster conclude about the history of the universe?
两个星系发生撞击，星团中产生数十亿恒星。最亮最密的星团叫做超级星团。
As the two galaxies smash together, billions of stars are born in clusters.
一些星系单独出现或成对出现，但它们更经常以叫做星群、星团和超级星团的较大的星协的组成部分来出现。
Some galaxies occur alone or in pairs, but they are more often parts of larger associations known as groups, clusters, and superclusters.
