国外媒体:科学家发现类似地球的星球

（单词翻译）

Gliese 581g is the sixth planet to be found circling a dwarf¹ star some 20 light-years away, in the constellation² of Libra. On paper it looks good – three times the mass of the Earth with possibly a rocky surface and enough gravity to hold on to an atmosphere.

Gliese 581g是发现的第六颗围绕天矮星的星球，它位于20光年外天秤座附近。理论上它看起来很不错——质量是地球的三位，岩石表面并有足够的引力能吸引住大气层。

The researchers also promised shirt-sleeve weather in some regions, but not everywhere. One side of the planet is almost always in sunshine; the other almost always in darkness and estimated temperatures range from minus four degrees Celsius³ to a very hot 71 degrees. A year meanwhile would go by in just 37 days.

研究者也发现有些地区有着温暖的气候，但并不是所有的地方都是这样。星球的一侧总是处于阳光中，另一侧总是处于黑暗中，温度估计从零下从读到零上71度。一年只有37天。

Of course, whether life could really be supported on Gliese 581g will need much more investigation⁴ and, most probably, technologies which don't exist yet. But the astronomers⁵ say planet hunting is getting easier and they were surprised how quickly they detected the tell-tale signs of this distant body, using ground-based telescopes.

当然，Gliese 581g上是否适合生命生存还需要很多的调查，而且，很可能这方面的技术并不纯在。天文学家说发现星球变得更加容易，当他们用地对空望远镜很快就发现这个遥远天气的明显迹象时，他们很惊讶。
