The guys at EarthSky.org took it upon themselves to answer that question. You should read the whole article, really, but for those of us with shorter attention spans, here’s the bullet point:

It’s a total lunar eclipse. The phrase blood moon is new (as of this year) to astronomers, but 2 pastors wrote a book that referred to blood moons last year. They use the phrase to refer to the full moons of the upcoming tetrad (four successive total lunar eclipses, with no partial lunar eclipses in between, each of which is separated from the other by six lunar months.) But, um, they’re also suggesting that these next lunar eclipses are signs of end times.¬†

Fun Fact: There are a total of 8 tetrads in the 21st century (2001 to 2100.) Smart money says the earth will still be here after all of them.

Blood Moon" is a completely new pop culture phrase for a total lunar eclipse. Frankly it sounds like the title of a Twilight movie to me, and the fact that it was most likely coined by a pastor who claims last night’s eclipse is a sign of end times makes me shudder every time it’s uttered. You’ll notice that in a 2 minute talk about total lunar eclipses, not once does NASA mention the phrase blood moon. But hey, whatever gets you looking at the stars, I suppose…

I love that the voice of Peter Griffin is the voice of science advocacy.

I was too much of a lazy sack to get out of bed at 1am to see this last night. Fortunately for me, this guy wasn’t.
