fresh-water life zone 淡水生物带
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。
Traveling on a nearly circular, 229-day orbit around both host stars, the planet lies outside the system's habitable zone—the region where liquid water, and thus life as we know it, could exist.
它的运行轨道为近似的圆形,以229天为周期,围绕着两个恒星作轨道运行,这个行星位于这个系统的可居住区之外——所谓可居住区,那里有液体水,正像我们所知道的那样,那里可能会有生命的存在。
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。
