Winter solstice

The whole Northern Hemisphere will experience the winter solstice today, but the farther north you get, the more obvious it'll be. In high-latitude areas like here in Siberia, the sun's arc cuts especially low across the sky as winter sets in. Today, this spot near the city of Raduzhny will barely get 5 hours' daylight.

Of course, even in the hotter climes of Earth's northern half, today is the shortest day of the year. So, while you wait for the long night to set in, make those daylight hours count!

冬至

今天整个北半球都将经历冬至，但你越往北走，冬至就越明显。在西伯利亚这样的高纬度地区，冬天来临时，太阳的弧线划破天空的距离特别低。今天，拉杜兹尼市附近的这一地区几乎没有5小时的日照。

当然，即使在地球北半球的炎热气候中，今天也是一年中最短的一天。所以，当你等待漫漫长夜来临的时候，让那些白天变得有意义！
