Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't expect it to be blue - the name has nothing to do with the color of our closest celestial neighbor.
A full moon occurred on Dec. 2. It will appear again on Thursday in time for the New Year's countdown.
So...if you're out tonight, look up in renewed wonder.
Glory to God in highest heaven,
Who unto man His Son hath given;
While angels sing with tender mirth,
A glad new year to all the earth .
