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。

Because if you found one in the habitable zone, would that mean it had life?

如果你在适合居住地带发现了一颗行星，就能说明这里有生命吗？

We are finding Earth-size planets. Not in the habitable zone.

我们正在搜索不在适居带的地球般大小的行星。

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.
