在地球上,我們看見月亮的彎彎光輝彷彿在擁抱著那微弱的夜邊,這真是一幅美麗的天文場景!這張特別的照片是在4月19日晚上拍攝的,那天的月亮只有兩天大,正好在它的橢圓軌道裡靠近地球的最近點。當時,這月亮還與美麗的昴宿星團在天空中相近。雲朵把月光變得柔和,讓昴宿兄弟們聚集在月亮亮亮的彎月下,透過那微弱卻色彩繽紛的月暈來看。月亮的暗面閃著地球的反光,這就是地球光,來自於地球自己的陽光。這柔和的月光,也叫做“老月亮在小月亮的懷抱裡”,在北半球的春天通常會更加明亮。而目前,月亮會每個月在地球的天空裡靠近昴宿星,每當月亮正處於彎月相時,最容易看到這些美麗的親密接觸。
原文:
Sunlit arms of a crescent moon seem to embrace the faint lunar night side in this dramatic celestial scene 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 brighter 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.
