A Picturesque Equinox Sunset

Explanation: What’s that at the end of the road? The Sun. Many towns have roads that run east – west, and on two days each year, the Sun rises and sets right down the middle. Today is one of those days: an equinox. Not only is today a day of equal night (“aequus”-“nox”) and day time, but also a day when the sun rises precisely to the east and sets due west. Featured here is a picturesque road in northwest Illinois, USA that runs approximately east -west. The image was taken during the March Equinox of 2015, and shows the Sun down the road at sunset. In many cultures, this March equinox is taken to be the first day of a season, typically spring in Earth’s northern hemisphere, and autumn in the south. Does your favorite street run east – west? Tonight, at sunset, you can find out with a quick glance.

说明: 路的尽头有什么?太阳。许多城镇有东西向的道路,而每年有二次太阳会从马路的正中央升起与落下。今天就是这样的日子:春分,今天不仅是日夜等长,而且也是太阳从正东升起,从正西落下的一天。这张摄于2015年3月春分日落时分的美丽影像,呈现了落日从美国伊利诺州西北部一条接近东西向的马路西沉的景观。在世界许多文明里,春分标志了北半球春季或南半球秋季的第一天。你钟爱的街道是东西向的吗?在今天的日落之时,只要一瞥就能看出来。
