城市电网传递了这种天象(The city grid delivers this celestial phenomenon)

在秋分和春分期间，当太阳在芝加哥西面和东面街道两旁的建筑之间直接升起或落下时，就会出现被称为芝加哥柱的天象。这座城市几乎完全对齐的网格是这次活动的主因。

During the fall and spring equinox, the celestial phenomenon known as Chicagohenge occurs when the sun rises or sets directly between the buildings lining Chicago’s west- and east-facing streets. The city’s almost perfectly aligned grid is responsible for the event.
