In this carousel, you can see how the terminator line—the imaginary line dividing day and night—has shifted over the past six months. Swipe left to see how on 21 December, the day of the solstice, the terminator line reached its greatest angle relative to the Earth’s axis (about 23.5 degrees). The solstice is celebrated in many cultures around the world, with traditions such as the Persian Yalda and the Northern European Yule. We’d love to hear about yours!

This is so magnificent
