百分之二的月亮
A Two Percent Moon

年輕的新月可能很難看到。這是因為當月亮顯示出它的新月期（年輕或年老）時，它在地球的天空中永遠不會遠離太陽。儘管天空依然明亮，但在這個傍晚的夜景中，一彎纖細的月牙還是清晰可見。這張長焦快照拍攝於 8 月 24 日，日落時分月球非常靠近西方地平線。在約 1 . 5 天的狹窄新月階段，可見的陽光部分僅佔月球近側表面的 2 %。在加那利群島航天中心，一個用於與太空飛行器通訊的可轉向無線電天線正對著月球表面的百分之二。日落時分的天空呈現粉紅色，部分原因是撒哈拉沙漠的細沙和塵埃被盛行風吹起。
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.
