在某種程度上,芝加哥就像是一座現代巨石陣。方向是從東到西,時間就是今天。 今天,以及每一個春分日,太陽都會準確地落在西邊,地球上的任何地方都是如此。因此,今天在芝加哥,太陽將直接落在赤道上排列整齊的街道和建築上,這一事件被稱為 #芝加哥巨石陣#。 這裡展示的是 2017 年 9 月中旬春分時節沿上瓦克大道(Upper Wacker Drive)部分路段拍攝的芝加哥日落照片。 不過,許多城市都有與地球自轉軸對齊的街道或其他地貌。因此,很有可能你最喜歡的街道也是東西走向的。今晚日落時分,只需匆匆一瞥,您就能發現這一點。
原文:Chicago, in a way, is like a modern Stonehenge. The way is east to west, and the time is today. Today, and every equinox, the Sun will set exactly to the west, everywhere on Earth. Therefore, today in Chicago, the Sun will set directly down the long equatorially-aligned grid of streets and buildings, an event dubbed #chicagohenge. Featured here is a Chicago Henge picture taken during the equinox in mid-September of 2017 looking along part of Upper Wacker Drive. Many cities, though, have streets or other features that are well-aligned to Earth's spin axis. Therefore, quite possibly, your favorite street may also run east - west. Tonight at sunset, with a quick glance, you can actually find out.
