The new discovery set the record for the most habitable-zone planets found around a single star.

这一新发现创造了单恒星发现最多可居住带行星的记录。

First, a climate conducive to life on Earth depends upon the extraordinarily narrow orbital parameters that define a continuously habitable zone where water can exist in a liquid state.

首先，地球上适宜生命存在的气候取决于极其狭窄的轨道参数，这些参数定义了一个持续可居住的地带，在那里水可以以液态存在。

Exoplanet hunters announced a new world orbiting in its dim star's habitable zone, the not-too-hot, not-too-cold region where liquid water is stable and life could potentially find a foothold.

太阳系外行星搜索者宣布发现了一个新行星，环绕其遥远恒星的可居住带运行，这一区域既不太热，也不太冷地区有稳定的液态水，有可能成为生命的一个立足之地。

If so, promising planets may have been sterilized by solar flares or frozen in the past, which wouldn't be reflected in present-day habitable-zone calculations.

This range is called the habitable zone - or colloquially, the Goldilocks zone.

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.
