Winter Solstice

Tonight is the longest night of the year. The earth's axis is at its maximum tilt away from the sun. It has happened every year for eons. Ancient civilizations have marked this occasion for millenia, using observatories such as Stonehenge and New Grange. It is perhaps the most important date in the history of mankind, since it represents the point at which the light returns and days get longer. A very powerful sign of hope as the world seemed to plunge endlessly into cold and darkness.
