一颗行星是否能够维持生命取决于它的恒星--即它的"太阳"--的大小和亮度。
Whether a planet can support life depends on the size and brightness of its star, that is its 'sun'.

Are there intelligent species living far beyond our solar system?
一些研究人员认为，拥有厚厚大气层和液态甲烷湖的“泰坦”是太阳系内最有可能发现地外生命的天体。
Some researchers think that Titan, with its thick atmosphere and lakes of liquid methane, is the likeliest spot to find extraterrestrial life in our solar system.
在真正的意义上，死肉产品是没有生命支持的，但水果是生食食品并且是太阳能的储存房。
Dead meat products are not life supporting in the real sense but fruits are live foods and are a store house of solar energy.

There's probably no intelligent life in the outer solar system.
从月亮反射的太阳光形成一个地球大气层的“指纹”，可以帮助天文学家断定他们发现的那些太阳系之外的行星上是否孕育着生命。
Sunlight that bounced back from the Moon carried a fingerprint of the Earth's atmosphere that could help astronomers determine if the extrasolar planets they're finding harbour life.
但是，研究者们认为一种近似的技术可被用来寻找太阳系以外行星上生命的足迹。
But the researchers say a similar technique could be used to find signatures of life on planets orbiting other stars.
由于我们正在太阳系寻找生命迹象，所以，我们的思维必须更开阔一些，角度更多一些，对未知的生命进行研究。
As we pursue our efforts to seek signs of life in the solar system, we have to think more broadly, more diversely and consider life as we do not know it.
尽管任何有多个太阳的太阳系都提供了巨大的焦化机会，他们都不会给生命以可乘之机。
While perhaps offering great tanning opportunities, any solar system with multiple SUNS would probably never allow life to develop.
