This year wraps up with a rare event! A total lunar eclipse—of the full Moon—on the winter solstice! A triple whammy!
Delightfully, this eclipse will be fully visible from North America. The partial eclipse begins in the wee hours of December 21 at 1:32 A.M. (ET) with totality starting at 2:40 A.M. (For those on the West cost, the show begins on the 20th!)
With the total eclipse, we will enjoy a celestial canvas of superb beauty. A lunar eclipse occurs when the Earth passes between the Sun and the Moon. In this alignment, the shadow of the Earth falls upon the Moon, dimming the Moon and giving it unusual coloring, ranging from muted gray to coppery orange.
While every eclipse is special, this one is attended by many stars and constellations that are beautiful in their own right. See more—plus, a special Sky Map!
