有一天，一位冒險的天文攝影師來到阿爾卑斯山的高峰。他期待著看到天空中兩道美麗的銀河拱門：一邊在日出前，另一邊在日落後。不過，當夜幕降臨時，他驚訝地發現天空中有三道拱門！除了銀河的內外兩道拱門，還有一道非常微弱的黃道光，它連接了這兩道銀河拱門。黃道光是陽光照射到太陽系內部的塵埃上所形成的。這讓攝影師驚呼不已，他花了40個小時來處理和組合那些夜晚拍攝的照片，最後完成了這幅美麗的三拱門全景圖。這故事告訴我們，大自然總能帶給我們驚喜，只要我們願意去觀察和探索！

Why are there three arches across the sky instead of two? Last month, after being dropped off by a helicopter at a high mountain peak in the Alps near the Swiss Italian border, an adventurous astrophotographer expected two arches of our Milky Way galaxy to be visible during the night. These were the inner arch looking in toward the center of our galaxy on the left, visible just before sunrise, and the outer arch on the right visible just after sunset. But there were three arches. The surprised astrophotographer soon realized that the sky was so dark that an entire arc of faint zodiacal light was also noticeable — sunlight scattered by inner Solar System dust. And it artfully connected the two Milky Way arches! The next morning a helicopter picked the astrophotographer back up, and after 40 hours of processing and combining that night’s images, the featured triple-arch 360-degree panorama resulted.
