This is beautiful. Sorry about the potentially noob question: is there an API you plug into for the live moon phase?

I'm building an app that could do with this live feed if it's easily available.

If all you need is the phase it is easily calculated; there are several examples in Google

Thanks. I wanted the graphic of the moon that comes along with it, but not sure if that's generated procedurally or through the API? (as you can tell I'm a complete noob when it comes to this stuff). Currently I just use images of each stage of the moon, but it's static so not the most accurate.
