It hasn't happened for over three centuries, but last night Northern Colorado and all of North America was treated to an early Christmas present, a Total Lunar Eclipse. We have pics in case you missed it! From

Hanging high in the sky, the moon slowly turned from bright silver into a red disk early Tuesday.

A total lunar eclipse occurs when the Earth casts its shadow on the full moon, blocking the sun's rays that otherwise reflect off the moon's surface. Some indirect sunlight still pierces through to give the moon its eerie hue.

The 3 1/2 hour celestial spectacle was visible from North and Central America where skies were clear. Portions of Europe and Asia only caught part of the show.

The totality phase -- when the moon was completely immersed in Earth's shadow -- lasted 72 minutes.
