壹苹派生活美语　月亮的神秘灰光（二）

　　When Leonardo da Vinci wrote about earthshine, he suggested that it might be caused by sunlight reflected from the Earth’s oceans. He was almost completely correct, except for one detail. Most of the reflected sunlight actually comes from the clouds in our atmosphere. The reflected light from the Earth is bright enough to light up the side of the Moon that isn’t receiving direct sunlight. The Da Vinci glow is not easy to see. Conditions need to be just right for the faint glow to appear.

　　李奥纳多．达文西写到地球反照时，他认为这可能是由地球海洋反射阳光引起的。除了一个细节之外，他几乎完全正确。大部分的反射阳光其实来自我们大气中的云层。从地球反射的光够明亮，足以照亮月亮上没有受到阳光直射的一面。达文西灰光并不容易看到。条件必须刚好达成才会出现微弱的光辉。
