The Darkest day in 456 years…  North and Central America will be able to view a full lunar eclipse starting Tuesday morning, Dec. 21. This eclipse is also a special one—it falls on the winter solstice, the transition between fall and winter, and it is the shortest day of the year in the northern hemisphere. It has been 456 years since the last time these two celestial events coincided.
