The world will witness an extremely rare event in the sky on the night of December 20 to 21 (yes, tonight!). First time in 372 years a red moon total lunar eclipse coincides with winter solstice, the shortest day and longest night of the year.
The solstice will not be seen, but North and South America, as well as the northern and western parts of Europe, and a small area of northeast Asia should get a great view of the total eclipse of the moon. During a lunar eclipse, the earth is exactly in line between the full moon and the sun, blocking the sun’s light from bouncing off the moon.
A minor meteor shower is expected to send a few shooting stars across the sky during the height of the eclipse. No telescopes are required to enjoy the eclipse. The event could be seen with the naked eye or with binoculars.
NASA has created a Flickr group for moon watchers to post their pictures of the event.
Space.com provides a detailed viewer's guide for the eclipse on this link.
