The orb is shopped. It's either that or just some light reflections in the lens of the camera.
The "alien" looks more like a growth from the tree it's peeking around from. Or a growth from a tree behind that tree.
What I think happened here is that someone took this picture, and then someone saw it and thought that the tree growth looked like an alien and then for some stupid fucking reason decided to put a lens flare in the image. So basically what's happening here is we've all been trolled by someone with photoshop.
Come on guy, with the technology available today, they can put a monkey sucking off a bum infront the white house and make it seem legitimate. So, I conclude that this is fake.

The can be made easily by anyone with little photoshop skills. As for the "alien," I will agree with 420. There is ton of tools/software available that can probably make it.
Honestly, I don't see why this is even up for debate..
