A Siberian solstice. 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 five hours of 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!
