【英语时差8,16】类地行星探测器（下）

（单词翻译）

 TPF will be able to search the habitable zones of stars located up to fifty light years away, analyzing¹ the composition of planets’ atmospheres. It will look for gasses that signal the possibility of life, gasses such as oxygen, water vapor², methane³, and carbon dioxide. And TPF will be capable of taking pictures that are one-hundred times more detailed⁴ than the photographs of the Hubble Space Telescope. Many astronomers⁵ are hopeful that these new telescopes will lead to a groundbreaking discovery of life elsewhere in the universe. Regardless of what discoveries they may yield, TPF and other space telescopes in development promise to bring exciting changes to space exploration.
