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。

If the source of Enceladus' south polar geysers, discovered by Cassini in 2005, is indeed liquid water, then the geysers will transport the dissolved sodium into space.

如果2005年我们通过卡西尼探测器在土卫二南极地区发现的冰晶喷泉，实际上是土卫二内部的液体水从土卫二逃逸的出口。那么这些冰晶喷泉也许就是现在被发现的钠元素的起源地。
