He said there are two ways to interpret the signals from Gliese 581.

他说有两种方法可以检验葛利斯581的信号。

Gliese 876 is a small, red star with about one-third the mass of the sun.

“格里斯876”是一颗小型红色恒星，其质量约为太阳的三分之一。

Gliese 581g has a mass three to four times Earth's, the researchers estimated.

研究人员估测gliese 581g行星的质量大约是地球的3到4倍。

Even if Gliese 581c turns out to be void of little green men, there is time yet.

即使人们最终发现Gliese 581c上面并没有什么小绿人，我们有的是时间。

Like our solar system, the planets around Gliese 581 have nearly-circular orbits.

Gliese 581周围的行星拥有同太阳系的行星一样类圆形轨道。

Like the solar system, the planets orbiting Gliese 581 have mostly circular orbits.

和太阳系一样，围绕着Gliese 581运行的行星轨道大部分都是圆形的。

The planet orbits a dim red dwarf star 20 light years from Earth called Gliese 581.

这颗行星所绕行的是一颗暗淡的红矮星，距地球20光年远，名为Gliese 581。

The other newfound planet, Gliese 581f, is outside the habitable zone, researchers said.

研究人员称，另一颗新发现的行星是Gliese 581f，位于适宜居住区域之外。

Unfortunately, subsequent research has tempered the initial excitement over Gliese 581 c.

不幸的是，接下来的研究消退了对格利泽581 c的热情。

The planet – Gliese g – appears to have an atmosphere and gravity similar to that of Earth.

这颗行星—格里斯g—大气和重力与地球相似。

According to theory, a planet the size and mass of Gliese 581c should be rocky, like the Earth.

根据这一理论，象Gliese 581c这么大尺寸和体积的行星应该象地球一样，岩石很多。

The newly found "Goldilocks" planet, called Gliese 581 g, lies in between the hot and cold ones.

最近发现的Gliese 581 g不冷不热，正好位于之前两颗行星之间。

It found that Gliese 581g has a mass three to four time the Earth's and orbits its star in just under 37 days.

Gliese 581g的质量是地球的3 - 4倍，并且公转时间仅为37天。

Unlike the previously discovered planets, Gliese 581g lies squarely in the region of space were life can thrive.

和从前发现的行星不同，Gliese 581g幸运的正好落在了适合生命繁衍的区域。

The previous five planets found around Gliese 581 were named b to f, making the latest discovery Gliese 581g.

早先在Gliese 581周围发现的五颗行星以b到f来命名，最新的一颗则被命名为Gliese 581g。

It is orbiting a star called Gliese 876, 15 light years from Earth, with an orbit time of just 1.94 Earth days.

这颗行星围绕着一颗名为“格里斯876”的恒星运转，该恒星距地球15光年，绕轨道运行一周的时间约为地球上的1.94天。

The planet in question orbits a star called Gliese 581 that lies a mere 20 light years away in the constellation Libra.

我们这颗行星围绕一颗称为Gliese 581的恒星运转，该恒星距地球仅20光年，位于天秤座。

When it was announced last September, Gliese 581g was heralded as the first known planet that could harbor alien life.

去年九月份宣布发现它时，大家把葛利斯581视作第一颗可能孕育生命的星球。

That's what a French team did for the planet Gliese 581d, which orbits a red dwarf star about 20 light-years from Earth.

一个法国团队就对就对格雷司581d行星这样做过，这个行星环绕着距离地球20光年的一颗红矮星运转。

Scientists were surprised by the discovery because Gliese 581d was previously ruled out as a habitable planet candidate.

科学家们对于这项发现感到非常意外，因为在此前格利泽 581d一直被排除在适宜居住的星球之外。

The one that the Swiss team thinks it hasdiscovered is in orbit around a star called Gliese 581, some 20 light yearsfrom Earth.
