The ideal discovery would be a planet similar in composition to Earth that lies within the Goldilocks Zone and orbits a stable star.

理想的情况是这样的：在居住区内发现和地球组成结构类似的行星，并且围绕稳定的恒星公转。

This newest planet, No. 5, resides in the habitable zone, about 0.8 Earth-sun distances from its star.

最新发现的这颗5号恒星，位于可居住区内，距离它的恒星距离为地-日距离的0.8倍。

The planet is in the "Goldilocks zone" of space around a star where surface temperatures are neither too hot nor too cold for liquid water to form.

这颗行星幸运的位于其恒星附近的“可居住带”，地表温度适中，这使液体水的形成成为了可能。

They were also able to extrapolate whether those super-Earths were likely to be orbiting in the habitable zone around the star.

The astronomers who will use these telescopes are particularly interested in finding any Earth-like objects in the so-called habitable zone around a star, where temperatures permit water to exist in a liquid state.

"What's particularly interesting is four new planets - less than twice the size of Earth - that are potentially in the habitable zone, the location around a star where it could potentially have liquid water to sustain life, " Dr Burke told BBC News.
