There Will Be No Green Moon Tonight
It's your favorite space ranger here. I love keeping you up to date with an astronomical event here and there. I also love busting fake memes.
First off, the full moon was on April 11th. In fact, there will probably only be a sliver a moon tonight.
Next up, there is no combination of astronomical events that ever turns the moon green. That's it, it's never going to happen.
Basically, what we have here is some people having fun with the "420" concept this Thursday. I know some of you are going, "no duh!" But I saw the green moon meme more than once with someone saying "really?" underneath it.
So enjoy your little 420 holiday. Maybe you can spend a little time staring at the moon and contemplating the wonder of it all, but the moon or the part of it that can be seen will be it's plain old silvery white color.
