On Christmas eve this year, NASA told us to look up at the skies. Before you think you guessed it, this wasn't a command to perform the act of 'Santa-watching'; identifying a magical flying sleigh being pulled along by magical flying reindeers.
Instead, there was something else in the sky that was very rare and wonderful, that you would be lucky to get a glimpse of in your lifetime.
From 23:11GMT until Christmas morning, there was a rare full cold moon in the sky.
The moon was surely a sight to behold:
NASA's John Keller had some insightful remarks about the moon as everyone waited up to see the first full cold moon since 1977:
As we look at the moon on such an occasion, it’s worth remembering that the moon is more than just a celestial neighbor.
The geologic history of the moon and Earth are intimately tied together such that the Earth would be a dramatically different planet without the moon.
Bring on 2034 when we will see the next cold full moon.
