Explanation: On March 23 early evening skygazers could watch Venus and a young crescent moon, both near the western horizon. On that date Earth’s brilliant evening star, faint lunar night side and slender sunlit crescent were captured in this telephoto skyscape posing alongside a church tower from Danta di Cadore, Dolomiti, Italy. Of course the subtle lunar illumination is earthshine, earthlight reflected from the Moon’s night side. A description of earthshine, in terms of sunlight reflected by Earth’s oceans illuminating the Moon’s dark surface, was written over 500 years ago by Leonardo da Vinci. On March 24, from some locations the Moon could be seen to occult or pass in front of Venus. Around the planet tonight, a waxing lunar crescent will appear near the Pleiades star cluster.

说明: 在2月23日入晚时分的西方地平线附近，观星者可同时见到金星与新月。这幅以长焦镜头拍摄的天空影像，就记录了在那一天，从意大利多洛米蒂山脉的Danta di Cadore村看出去，教堂钟楼之旁悬着地球天空的明亮昏星、暗淡的月球夜面、及日曜的纤细蛾眉月。想当然耳，照耀月面的微光是地照，或者说是从月球夜面反射的地照光。而远在500多年前，达芬奇就指出映在月亮黝黑夜面的地照，是从地球海洋反射的阳光。3月24日那天，在某些地点见到了月掩金星的景观。今晚在全球各地，皆可见到上弦蛾眉月与昴宿星团的近合。
