太阳敏感器的测量精度主要受地球反照的影响。
The measurement accuracy of sun sensor is mainly influenced by earth albedo.
你可以看到地球的光谱，这是地球反照光谱。是一个非常明确的讯号。
You can see the spectrum of the Earth, this Earthshine spectrum, and that is a very clear signal.
对地球反照光的分析显示：这个行星拥有一个云雾大气层，还被海洋和一些植被所覆盖。
The analysis of earthshine correctly revealed that the planet it came from has a partly cloudy atmosphere and is covered with oceans and some vegetation.
我们怎样寻找（太阳）系外行星上的生命？步骤一：把地球当做一个（太阳）系外行星进行研究。这是研究人员最近根据地球反照光想到的一个办法。
How can we search for life on exoplanets? Step one: examine the Earth as if it were an exoplanet. That's the idea behind a recent look at earthshine.
我们记录辐射收支的一种方法是观察地球上不同表面的反照率。
One way we keep track of the radiation budget is by looking at the albedo of the different surfaces on the planet.
新月抱旧月“只不过就是月球表面上正处于黑夜的那一部分被地球的反射光反照的结果。”
"The old moon in the new moon's arms" is nothing but that part of the moon's surface on which it is night, lighted up by earth light.
它把光照反射到外太空（也就是人们所熟知的增加地球的反照率）同样也能降低地球的温度。皇家学会的笔者认为有两种途径实现此作用。
Reflecting sunlight back into outer space (increasing the Earth’s albedo, as it is known) would also cool the planet, and the Royal Society’s authors consider two ways of doing so.
海冰的消退以及冰雪的融化降低了地球的反照率，这将导致温度继续增高冰雪继续消融。
Sea ice retreat and snow melt reduce Earth's albedo, which can lead to increased warmth and further melting.
他们对地球的反照光进行了测量：太阳光被地球反射到月球，然后又反射回来。
They measured earthshine: sunlight that reflects off the earth, hits the moon and bounces back.
他解释道：“因为你改变了地球的反照率。”
