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。

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。

In September, astronomers announced that they had discovered an alien world in the habitable zone of its star.

今年九月，天文学家宣称他们发现了一个事宜居住的外星球。

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.
