这是一项令人着迷的观测结果，因为当我们最终超越空间站后，特洛伊小行星相对稳定和距离接近的特点使其成为宇航员太空任务的可能目标。
It is a fascinating observation because the relative stability and proximity of Trojans would make possible targets for astronaut missions when we eventually go beyond the space station.
这是地球上一个正常的元素循环，我的科学沿时间回溯，表明我们的地球80%的时间曾是一个绿色、温暖、潮湿的行星。
It is a normal element cycled around in the earth and my science, which is looking back in time, is saying we have had a planet that has been a green, warm wet planet 80 per cent of the time.
这是一个太空望远镜，能够观察由行星在主星(恒星)前横移造成的最微弱的亮度变化。如果允许我们探测类似地球的行星，那么需要达到该亮度变化的十万分之一。
It's a space-borne telescope that will be able to measure the tiniest dimming (caused by a planet crossing in front of the host star), to one part in 100,000, allowing us to detect Earth-like planets.
