宜居行星

今年八月，来自瑞士的一个研究团队报告称他们发现了另一个疑似宜居行星“HD85512b”，距离地球36光年。

In August , a team from Switzerland reported that another planet called HD 85512b and 36 light years away seemed to be habitable .

今年五月，法国天文学家发现宜居行星“格利泽581d”，该行星比“开普勒22b”要近得多，距离地球约20光年。

In May , French astronomers identified Gliese 581d , pronounced " gleezer , " which is far closer at around 20 light years away .

确认发现近地宜居行星

Confirmation of the discovery of a nearby habitable planet

美国国家航空航天局的科学家表示，银河系中遍布潜在宜居行星，至少有3亿颗。

Our galaxy is filled with potentially habitable planets -- at least 300 million of them , according to NASA .

根据发表在《天文学杂志》上的一项研究，银河系中大约有3亿颗宜居行星。

According to research released in The Astronomical Journal , there are roughly 300 million potentially habitable worlds in our galaxy .

对于我们科学团队来说，火星作为一个生命宜居行星，显得十分诱人，格罗青格说。

As a science team , Mars is looking very attractive to us as a habitable planet , Dr. Grotzinger said in an interview .

这类宜居行星过去都只是在科幻小说中才会出现。它们在宇宙中可能有很多，据研究人员估计，在银河系有多达400亿颗环境与地球类似的行星。

Once the stuff of science fiction , such habitable planets may be common in the cosmos -- as many as 40 billion Earthlike planets in the Milky Way , researchers estimate .

门德斯说，这项发现的主要一点是行星的大小，目前为止，全部可能宜居的行星体积都较大。

' The main point of this discovery is the size of the planet . So far , all potentially habitable planets were big ones . '
