科學圖說 Scientific introduction

朔的前後幾天，月球的暗部被地球反射的太陽光線隱隱照亮，形成「新月抱舊月」的天文現象，又名「灰光」。灰光是一種常見的天文現象，但前景的選擇尤為重要。清華大學天文臺始建於1931年，原名氣象臺，為中國大陸重點文物的保護單位。將天文臺和「灰光」這種天文現象拍攝在一起，顯得更有意義。

The first few days after a new moon, the dark part of the moon is faintly illuminated by sunlight reflected from the earth to create the astronomical phenomenon known as “old moon in the new moon’s arms”. It is also referred to as “ashen light”. Ashen light is a common astronomical phenomenon. The Tsinghua University observatory was constructed in 1931. It was an important cultural artifact preservation unit in China. Photographing this observatory together with ashen light makes this image more meaningful.
