年轻的新月很难看到。这是因为当月亮出现新月阶段（年轻或年老）时，它在地球的天空中永远不会远离太阳。但即使天空仍然明亮，在这张傍晚的天空中，一个细长的月光清晰可见。这张长焦快照拍摄于8月24日，日落时月球非常接近西方地平线。在大约1.5天前的狭窄月牙形阶段，可见的阳光照射部分仅占月球近侧表面的2%。在加那利群岛航天中心，一个用于与航天器通信的可操纵无线电天线倾斜于月球的2%方向。日落的天空呈现出柔和的粉红色，部分原因是由于盛行风吹来的撒哈拉沙漠的细沙和灰尘。

A young crescent moon can be hard to see. That's because when the Moon shows its crescent phase (young or old) it can never be far from the Sun in planet Earth's sky. But even though the sky is still bright, a slender sunlit lunar crescent is clearly 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 tilted 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.
