在这张从地球上拍摄的引人注目的天景中，新月的阳光臂似乎拥抱着暗淡的月球夜晚。这张跟踪天空的单长焦曝光照片是在4月19日晚上拍摄的，当时一颗刚出生两天的月球在其椭圆轨道上接近近地点。在那一天，年轻的月亮也靠近天空中可爱的昴宿星团。随着月光被云遮住，昴宿星团的姐妹星聚集在月亮明亮的月牙下，透过微弱但色彩斑斓的月冕可以看到。月球的夜面是由地球反射的太阳光照亮的。月亮灰白色的光芒，也被称为“老月抱月”，在北半球的春天往往是明亮的。目前，月球的轨道使它每个月都在地球的天空中靠近昴宿星团，尽管当月球接近月牙相时，它们的紧密结合最容易被看到。

Sunlit arms of a crescent moon seem to embrace the faint lunar night side in this dramatic celestial view from planet Earth. The single telephoto exposure tracking the sky was captured on the night of April 19, when a two day old Moon was near perigee in its elliptical orbit. On that date, the young Moon was also close on the sky to the lovely Pleiades Star Cluster. With the moonlight dimmed by clouds the Pleiades sister stars gather below the Moon's bright crescent, seen through a faint but colorful lunar corona. The lunar night side is illuminated by earthshine, sunlight reflected from the Earth itself. The Moon's ashen glow, also known as the "old moon in the young moon's arms," tends to be bright in the northern hemisphere spring. And for now, the Moon's orbit takes it near the Pleiades stars each month in planet Earth's sky, though their close conjunctions are easiest to see when the Moon is near a crescent phase.
