路的尽头是什么？太阳。许多城镇都有东西走向的道路，每年有两天，太阳从中间升起和落下。今天，在世界上的一些地方（明天在另一些地方），就是这样一个日子：春分。这一天不仅是夜晚（“aequus”-“nox”）和白天时间相等的一天，而且也是太阳从东方精确地升起，在正西方落下的一天。这里展示的是加拿大阿尔伯塔省一条风景如画的乡村公路，大致是东西走向的。这张特色图像是在2021年9月春分期间拍摄的，但每年的几何形状都是一样的。在许多文化中，三月春分被认为是一个季节的第一天，通常在地球的北半球是春天，在南半球是秋天。你最喜欢的街道是东西走向的吗？今晚，日落时分，你一眼就能找到答案。

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, in some parts of the world (tomorrow in others), is one of those days: an equinox. Not only is this 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. Displayed here is a picturesque rural road in Alberta, Canada that runs approximately east-west. The featured image was taken during the September Equinox of 2021, but the geometry remains the same every year. 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.
