It's going to be a white Christmas this year – not necessarily with snow, but with bright moonlight.
It's rare for Christmas to line up with the full moon. It won't happen again for another 19 years, until 2034, according to The Weather Channel, which spoke to a NASA moon expert.
The timing means that Christmas Eve will be the brightest night of the holiday season in the U.S. (As long as there's no cloud cover.)
No word from NORAD, the U.S. military agency that tracks Santa's flight around the globe every year, on how moonlight affects his travel plans.
