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. They shouldn’t have long to wait.

译：设计Cobe卫星就是要观察这些最大的物体结构，但天文学家想看到更小的热点，即，像星系中的星团和超星团这样一些局部物体的粒子。看来他们不必等待很长时间。

1. 本句主干为but连接的并列句。

2. but之前为被动句，即：Cobe/ is designed，主干为被动句，翻译时可译为主动。to see just the biggest structures为目的状语。

3. 后半句主干为主谓宾结构，即：astronomers /would like to see /much smaller hot spots as well，主干可直接顺序翻译即可。

4. all seeds of local objects like clusters and superclusters of galaxies为名词短语，充当hot spots 的同位语，解释其具体内容。
