The moon is about to be blackety-black, y'all.

On Friday, September 30, a rare black moon will rise in the skies of the Western Hemisphere — a phenomenon that hasn’t happened since March 2014, Cosmo noted

So, what exactly is a black moon?

According to AL.com, it’s when there are two full moons in a calendar month and is described as when the sun hits the side of the surface that's facing away from Earth on its dark side. The moon occurs around every 32 months and the last time we’ve seen one was in 2014.

Sounds pretty dope, huh? But here’s the deal: Because the sun’s not illuminating that side for us to see, the black moon will be pretty invisible to folks staring at the night’s sky. But there is an upside: Black moons are great for stargazing.

So go and get your constellation on! The lunar event starts at 8:11 p.m. Eastern Time/7:11 Central Time. And if you can’t make it this time around, you’ll have to wait a minute for the next one, which won’t happen until July 2019.

P.S: Please ignore those old wives tales that this is a symbol of something sinister or a sign of the apocalypse. The world isn’t going to end over a black moon. Now a black hole? That might be another story.
