brightest star in Centaurus; second nearest star to the sun

However, getting enough antimatter for the 26 trillion-mile, one-way trip to Alpha Centauri and storing such a volatile fuel for long periods is prohibitively expensive and difficult.

然而，要到达26万亿英里之外的半人马座阿尔法星，携带和储存足够量的反物质难度极大，这种燃料不仅状态不稳定，而且耗资不菲。

For now, the jury is still out on whether the Alpha Centauri system has smaller, Earth-like worlds in life-friendly regions, but Fischer expects answers shortly.

目前，对于半人马座阿尔法星系是否有类似于地球而且适合生命存在的区域，科学家仍然无法确定，但费希尔认为不久答案便可揭晓。

The action takes place on Pandora, a fictional moon in the Alpha Centauri star system.

影片发生的地点是位于阿尔法星系的潘多拉星球。

We「ve grown wary about these funky blue aliens, about the value of this 「revolutionary」 3-D look, about the convoluted back story required to get us to that blue moon in the Alpha Centauri system.

我们已经长大，会对这些质朴的蓝色外国人，对这个「革命性」的3D技术，对错综复杂的、让我们进入半人马座阿尔法蓝色卫星的背景故事产生疑问。

Interstellar travel is a daunting and humbling notion, but Alpha Centauri is an alluring target for such a trip: It is the closest star system to our own, and there might be planets in the system.

提到星际旅行，人们往往望而却步、自觉渺小，但半人马座阿尔法星系是一个很有诱惑力的目标：它是距离我们自己的太阳系最近的一个星系，而且可能有行星存在。

In recent years, astronomers have amassed data suggesting the possibility of an Earth-size planet orbiting Alpha Centauri b.

天文学家近年来搜集的数据显示，可能存在一颗地球那么大的行星，在围绕半人马座阿尔法星b旋转。

Fortunately, if life has taken root in the Alpha Centauri system, it is not likely to suffer this fate.

值得庆幸的是，如果半人马座阿尔法星系存在生命，它们遭受此厄运的可能性微乎其微。

The star, Alpha Centauri is the closest star besides our sun.

除了太阳之外， 半人马座a星离地球最近。

Their proposed destination is the Alpha Centauri star system, which includes two larger, sunlike stars in addition to Proxima Centauri.

他们提出的目的地是半人马座阿尔法星系(Alpha Centauri，又称南门二)，除了比邻星，其中还有两颗更大的类日恒星。

That」s not to say that Alpha Centauri doesn't have a habitable world of some kind—it would just have to be a planet like our own, rather than a moon.

但这并不代表半人马座阿尔法星不具有某种适宜居住的环境——它最好是类似于我们地球的行星，而不是卫星。

Matrixes from Alpha Centauri tend to be more angular in nature;

来自半人马α座的矩阵在性质上倾向有更多的角；

In Avatar: the white-yellow glow of Alpha Centauri a, a star very similar to our Sun, illuminates the giant gaseous planet Polyphemus and its tropical moon Pandora.

影片中：与我们的太阳非常相似的半人马座阿尔法甲发出淡黄色的光芒，光芒照耀下的是巨大的气态行星波吕斐摩斯和它的卫星——炎热的潘多拉。
