The eclipse tonight should be a pretty cool sight for those who can see it.

Three snow hikers watch the almost full moon rise behind the Weissfluhjoch in Arosa, Switzerland, on Dec. 20. There will be a total lunar eclipse visible from Britain on Tuesday morning, when the Earth casts a shadow onto the Moon. On the day of the winter solstice, December 21, the full Moon will start to pass through the cone of Earth's shadow at 6.32 GMT.
