Why is the Moon colourless(無(wú)色的)?
為什么月亮沒(méi)有顏色?
▼
Despite(盡管) appearances, the Moon is not entirely devoid(缺乏的) of colour.
盡管月亮看起來(lái)沒(méi)有顏色，但它也不是完全缺乏色彩。
Apollo astronauts described its colour as ‘brownish’. Careful study shows that the dark areas, or ‘maria’, display hints(暗示) of blue or brown while the highland areas have faint(模糊的) traces(痕跡) of yellow, pink and pale blue.
阿波羅號(hào)宇航員稱(chēng)其顏色為“褐色”。仔細(xì)研究表明，黑暗地區(qū)(或稱(chēng)“瑪利亞”)顯示出藍(lán)色或棕色的跡象，而高地地區(qū)有微弱的黃色、粉色和淡藍(lán)色的痕跡。
These differences are mainly due to varying(不同的) amounts(數(shù)量) of metals such as iron or titanium(鈦) in the surface minerals. Unfortunately, the human eye isn’t sensitive(敏感的) enough to pick out these slight differences in colour from a distance. However, much of the lunar(月亮的) surface contains minerals that are naturally grey and these dominate(控制) the colour we perceive(察覺(jué)) from Earth. AGu
這些差異主要是由于表面礦物中含有不同含量的金屬，如鐵或鈦。不幸的是，人類(lèi)的眼睛不夠敏感，無(wú)法從遠(yuǎn)處分辨出顏色的細(xì)微差別。而且，月球表面的大部分物質(zhì)都是灰色的，這是我們?cè)诘厍蛏细兄伾闹饕獊?lái)源。
