Cobe is designed to see just the biggest structures, but astronomers would like to see much smaller hot spots as well, the seeds of local objects like clusters and superclusters of galaxies.
Cobe 的设计只是为了观测最大的结构，但天文学家们也希望看到更小的热点，即星系团和超星系团等局部天体的种子。
Some galaxies occur alone or in pairs, but they are more often parts of larger associations known as groups, clusters, and superclusters.
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。
