一直以来，火星呈现的颜色被认为是液态水的作品，科学家认为是亿万年前流淌在这一行星表面的水锈蚀了岩石而造成的结果。

当前的计算机模型预测：近距离围绕恒星运行的炽热的木星类行星(巨大的气体球)只能像水星一样暗，后者能反射照射到它上面的大约10%的太阳光线。
Current computer models predict that hot-Jupiter planets-gas giants that orbit very close to their stars-could be only as dark as Mercury, which reflects about 10 percent of the sunlight that hits it.
为了解决全球气候变暖的问题，各种解决方案是千奇百怪的。例如“行星包围式地球工程”，可以减少到达地球表面的阳光。

而瑞士发现的那颗岩状行星上是否有生命，就要看它是否有大气层，大气层下面的水是 否以液态形式存在。
Whether there could be life on the Swiss team's rockyplanet depends very much on whether it has an atmosphere beneath which watercould exist in its liquid form.
证据包括从地球可探测到的小行星的化学组成、周围碎屑颗粒分布、或者温度方面的改变。
Evidence could include changes in the chemical composition of the asteroid, the size distribution of debris surrounding it, or other thermal changes that could be detected from Earth.
只要其中有行星表现出适合居住的可能性，科学家就将对其表面大气层的化学成分进行生物特征方面的研究。
And if any seem habitable, scientists will study the chemical content of their atmospheres for the hallmarks of biology.
我们已经知道了，坐在行星表面的情况。
The case that we actually know how to do fairly well is if you are just at the surface of the planet.
行星肥皂泡上的核火：我真对这些结果非常满意。这些特写表现了肥皂泡不同的一面，包涵表面的结构。
'Nuclear fires on planet bubble' : 'I'm really pleased with some of these results. The close-ups show a different side to bubbles, with the surface textures'.
如果你在为小行星会不会撞击地球而忧心忡忡，那么你应当清楚这样一个事实：由于地球引力而引发的小行星撞击，就好比飞驰的卡车，车头前面的格栅总是在不断吞噬着迎面扑来的飞虫。
If you happen to live in fear of asteroids, then here's a sobering fact for you: Our planet absorbs asteroid impacts like a truck grille eats bugs.
这些微行星体（planetesimals）的增长会用到几百万年到2千万年的时间，而最外面的部分最晚形成。
The accretion of these "planetesimals" is believed to take a few hundred thousand to about twenty million years, with the outermost taking the longest to form.
对摆线钢球行星传动进行了较全面的类型分析。
The type analysis of the cycloid steel ball planetary transmission is made.
他有两方面的证据：第一，现存的灾难性撞击的残骸与Baptistina和她的后代有相同的成分，这是必要条件，但并非充分条件，因为含碳的球粒状陨石在其它小行星上也有；
That is a necessary but not a sufficient condition, as the type of rock involved, called carbonaceous chondrite, is found in other asteroids, too.
所谓大大气层是指包围在某个行星或者其他巨大物体表面的一层气体。
The atmosphere is the layer of gases that surrounds a planet or other massive body.
我所居住的行星也是如此，丧失了太阳的引力控制，住在星球表面的我们丧生了。
The planet I lived on also did this, having no gravitational control of our Sun, but we lived on the surface and perished.
水星——太阳系最里面的行星—今天是东部最大的延伸。
Mercury - the solar system's innermost planet - is at its greatest eastern elongation today.
但通过这方面的努力，该研究小组还考虑到了偏振光的因素。因为行星的反照光往往会出现偏振，但恒星发出的光则不会如此。
But in this effort, the research team also took into account polarized light. Because light reflected off a planet is polarized. But light from the star is not.
这些愿景完全将地球物理层面的行星疗愈接纳为一种个人校准和扩展的必然结果。
These perspectives fully embrace geophysical planetary healing as an intrinsic consequence of personal alignment and expansion.
