December 21st: The Day the Sun Never Rose

The world didn't end on December 21st. (In fact, that was the 7th failed prediction of the end of the world in the last two years.)
But what DID happen?
It was The Day the Sun Never Rose. It was also The Day the Sun Never Set.
December 21st was the Winter Solstice in the northern hemisphere. That's the day when Earth's north pole was pointed completely away from the Sun.
If you lived north of the Arctic Circle, like Santa Claus, you would have experienced 24 hours of darkness. It was the day Sun never rose.
However, if you lived south of the Antarctic Circle, like many penguins, you would have experienced 24 hours of daylight. It was the day the Sun never set.

Imagine this image of Earth turning on its axis. Everything north of the Arctic Circle stays in the darkness of Earth's shadow and doesn't see sunlight. Everything south of the Antarctic Circle stays in the sunlight and never sees darkness.
Where did the Sun appear from your place on the globe?
So celebrate the changing of the seasons, and bundle up to enjoy the long nights of winter stargazing.
For the next six months, the nights will be getting shorter for us in the northern hemisphere and longer for those in the southern hemisphere.
