Both a total lunar eclipse and the winter solstice occur today - a celestial concurrence with a frequency of perhaps once a millennium.

In case your astrological [correction: astronomical - h/t Thomas Henry] vocabulary is in need of brushing up, a total lunar eclipse occurs when the Earth blocks the sun's rays and the moon is fully enshrouded by the shadow, and the winter solstice marks the sun's lowest arc in the northern sky.

So go look at the sky, wonder for a moment, and take part in a little piece of history.
