“我们已经对这些星球做了100多年的记录……但鉴于天文学家进行分析的方法，他们无法看见这种定相的不稳定，”雷恩德说。

"We've been recording these stars for over 100 years now... but the way astronomers were doing the analysis, they would not have seen any such phased jiggling around," Learned said.

地球目前的气候状态很是不稳定；在过去的70万年间，我们的星球大约经历了7次冰川时期。

The earth's current climate is something of an anomaly; in the past 700,000 years, there have been at least seven major episodes of glaciers spreading over much of the planet.
