太空最大望远镜“退休”

▍原文

'The little telescope that could' has retired. It changed how we see the universe.

After 16 years of incredible discoveries, NASA's retiring Spitzer Space Telescope is going gently into that good night, slumbering against a background of stars -- the very ones it helped study.

The infrared telescope completed science activities on Tuesday, relayed back data on Wednesday and on Thursday will enter a safe hibernation mode thanks to a command sent from the engineering team.
