在某种程度上，芝加哥就像现代的巨石阵。路是东向西，时间是今天。今天，每到春分，地球上的每一个地方，太阳都会完全朝向西方落下。因此，今天在芝加哥，太阳将直接落在长长的赤道排列的街道和建筑网格上，这一事件被称为#芝加哥巨石阵。这是2017年9月中旬春分期间拍摄的芝加哥巨石阵照片，沿着上瓦克大道的一部分拍摄。然而，许多城市的街道或其他特征与地球的自转轴很好地对齐。因此，很有可能，你最喜欢的街道也是东西走向的。今晚日落时分，你只需匆匆一瞥，就能找到答案。

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.
