This coming Tuesday could be quite interesting: in addition to the many winter solstice festivals carried out throughout the northern hemisphere, this year’s solstice also coincides with a total lunar eclipse for the first time in 456 years. The eclipse will be the first in three years and should be visible throughout North America and some of Europe. Look for the moon to appear pink — that is if you don’t have cloud cover and heavy snow.

For those taking note, December 21, 2010 also marks two years remaining in the countdown to the end of the 5,125 year Mayan Long Count Calendar, which famously ends on the winter solstice of 2012.
