原文:
What are those streaks of light in the sky? First and foremost, the arching structure is the central band of our Milky Way galaxy. Visible in this galactic band are millions of distant stars mixed with numerous lanes of dark dust. Harder to discern is a nearly vertical beam of light rising from the horizon, just to the right of the image center. This beam is zodiacal light, sunlight scattered by dust in our Solar System that may be surprisingly prominent just after sunset or just before sunrise. In the foreground are several telescopes of the Bosque Alegre Astrophysical Station of the National University of Cordoba in Argentina. The station schedules weekend tours and conducts research into the nature of many astronomical objects including comets, active galaxies, and clusters of galaxies. The featured image was taken early this month.

🌌✨ 看看這些天空中的光線！首先，這道拱形結構是我們的銀河系——銀河帶。這條銀河帶中可見數以百萬計的遙遠星星，還有許多黑暗塵埃的陰影。更難辨認的是圖像中心右側幾乎垂直升起的光束，這就是黃道光（Zodiacal Light），它是太陽光被我們太陽系中的塵埃散射而成，通常在日落後或日出前會變得格外明亮。前景中是阿根廷科爾多瓦國立大學的Bosque Alegre天文物理站的幾個望遠鏡。該站安排周末導覽，並進行有關彗星、活躍星系和星系團等多種天文學對象的研究。這張圖片是在本月初拍攝的。
