　　Scientists have discovered a planet which could have the most Earth-like environment ever found - raising a 'very compelling case' for life there. 　　对于外星生命的探索，人们从未停止过。近来，科学家们发现了迄今拥有最为类似地球环境的行星，再次提升了地外生命存在被发现的概率。 　　Gliese 581g, located around 123trillion miles away, orbits a star at a distance that places it squarely in the habitable - or Goldilocks - zone, Nasa said. 　　美国宇航局宣称：“位于123百万亿英里之外的，Gliese 581g恰好位于一颗恒星的宜居带量程内。” 　　The research, the product of more than a decade of observations at the WM Keck Observatory in Hawaii, suggests the planet could contain liquid water on its surface. 　　作为夏威夷WM Keck天文台数十年的研究产物，该研究表明此颗行星表面或含液态水。 　　The new findings are based on 11 years of observations of the nearby red dwarf star Gliese 581 using the HIRES spectrometer on the Keck I Telescope by a team of planet-hunters from University of California (UC) Santa Cruz and the Carnegie Institution of Washington.

　　这项发现就是建立在一个研究小组的研究成果的基础之上。该小组成员主要由加利福尼亚大学圣塔克鲁斯分校的“行星猎人”和华盛顿卡内基研究所的研究人员们组成，他们通过使用加载在Keck1号天文望远镜上的HIRES光谱仪来观测Gliese581g附近的红矮星，用时11年。
