You must’ve heard about this by now, but I’ll mention it to make sure you know: there’s a full lunar eclipse happening tonight, and it just so happens that it’s also the winter solstice, a.k.a. the shortest day/longest night of the year. Just a coincidence, but a relatively rare one. Lunar eclipses aren’t super-rare- we get one about once every 2-3 years, but they can be pretty spectacular if the earth’s atmospheric conditions cast an eerie orange-red hue on the moon. There’s no way to know if that will happen for sure, but from my experience it happens more often than not. Unfortunately there’s a very good chance it will cloudy and/or raining tonight in middle TN, but if you’re elsewhere, good luck! It starts at about 1:30am EST, that’s 12:30am central, 11:30pm mountain, and 10:30pm pacific.

And I can’t help but post this comic from xkcd: I agree 100%
