小朋友們，有沒有注意到晚上天空中的小月亮呢？這是一個年輕的彎月，因為當月亮在彎月的形狀時，它總是在太陽旁邊，所以下午的天空還是亮亮的，但那一小段亮亮的月亮還是可以清楚地看到哦！這張照片是在8月24日拍的，當時月亮在西邊的地平線附近，就在日落的時候。這個彎月大約只有1.5天大，亮亮的部分僅僅是月亮的2%而已。你知道嗎？在加那利群島的太空中心，有一個可以轉動的無線電天線，它正在對著這個小小的月亮發送信號呢！而且，晚霞的粉紅色也是因為撒哈拉沙漠的細沙和灰塵被風吹過來的呢！
原文:
A young crescent moon can be hard to see. That’s because when the Moon shows it’s crescent phase (young or old) it can never be far from the Sun in planet Earth’s sky. And even though the sky is still bright, a slender sunlit lunar crescent is cleary visible in this early evening skyscape. The telephoto snapshot was captured on August 24, with the Moon very near the western horizon at sunset. Seen in a narrow crescent phase about 1.5 days old, the visible sunlit portion is a mere two percent of the surface of the Moon’s familiar nearside. At the Canary Islands Space Centre, a steerable radio dish for communication with spacecraft is titled in the direction of the two percent Moon. The sunset sky’s pastel pinkish coloring is partly due to fine sand and dust from the Sahara Desert blown by the prevailing winds.
