3月23日傍晚，天空观测者可以看到金星和一个年轻的新月，它们都在西方地平线附近。在那一天，在意大利多洛米蒂的圣彼得罗迪卡多雷的一座教堂塔楼旁，这张长焦照片捕捉到了地球上明亮的晚星、暗淡的月球夜侧和细长的阳光下的新月。当然，微妙的月球照明是地球的光，地球的光从月球的夜间反射。500多年前，列奥纳多·达·芬奇（Leonardo da Vinci）就地球海洋反射的阳光照亮了月球黑暗的表面，描述了地球的光辉。3月24日，从某些地方可以看到月球隐没或从金星前面经过。今晚在地球周围，一个盈盈的月牙将出现在昴宿星团附近。

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 San Pietro 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.
