Background
At night, people always raise head and look at stars. We may all have asked similar questions: are there any planets we can live other than earth? For decades, scientists and astronomers are devoted to these fascinating questions and have done lots of researches. Since the shining stars we can see with our naked eyes on earth are almost fixed stars like our sun, it’s absolutely impossible for life to exist there. Thus in order to search for second earth, the first thing to do is detecting Earth-sized and smaller planets in the habitable zone of stars. NASA’s Kepler Mission aims at this goal using the powerful telescope Kepler.
Kepler is designed to survey a portion of our region of the Milky Way galaxy to discover dozens of Earth-size
