Happy Solstace everybody!

I nicked this little idea from Scott Little about why Winter Solstace happens, and why it happens to be today. All info comes via Robert Roy Brit at Livescience:

While snow marks the beginning of winter for many people, the first official day of winter is Sunday, Dec. 21, known as the December solstice.

It’s a point in time that marks a transition in our planet’s annual trip around the sun.

The sun comes up each day because Earth rotates once on its axis every 24 hours or so. Seasons, and the arrival of the solstice, are a result of Earth being tilted 23.5 degrees on its spin axis coupled with the planet’s 365-day orbit around the sun.

Imagine Earth as an apple sitting on one side of a table, with the stem being the North Pole. Tilt the apple 23.5 degrees so the stem points toward a candle (the sun) at the center of the table. That’s summer for the top half of the apple.

Keep the stem pointing in the same direction but move the apple to the other side of the table: Now the stem points away from the candle, and it’s winter on the top half of the fruit. The very top of the apple, representing the north polar region, is in total darkness 24 hours a day.

Now, of course, I’m going to have to try this. The original article also has links to more information about tilt and ancient calendars and other kinds of goodies. Go check it out.
