Not only is tonight the winter solstice, but there is a full lunar eclipse, too! The last full moon on the solstice was 20 years ago; the last full lunar eclipse on the solstice was December 21, 1638.

Start here on the NASA site to read up about it–they’ll even have a live web cam (!). The eclipse should start about 11:30 p.m. tonight, with totality starting Tuesday morning at 12:41 a.m. and ending at 1:53 a.m. The whole thing will be happening in the western sky. I hope it’s not cloudy!

(Bonus activity: sing “Total Eclipse of the Moon” to the Bonnie Tyler tune. You’re welcome.)
