The important fact is, that most of the real estate that's accessible to us -- I'm not talking about the stars, I'm talking about the solar system, the stuff that's within reach for spacecraft and within reach of our earthbound telescopes -- most of the real estate is very cold and very far from the Sun.
重要的一个事实是 那些我们能够去得到的地方——注意 我不是在讲那些恒星 我是讲太阳系内部 那些通过宇宙飞船和太空望远镜 可以到达的地方 太空中大多数地方都很冷 离太阳也很远
