So we are going to go back to the moon to live underground. Kind of spoils it for me (watched too much UFO & Space 1999).

Is it me or does it look like an artifact (visual not alien)?

The article talks about possible methods of creation of this "skylight". Given it seems very nicely rounded, I'd say a meteorite impact was the most probable... It will be interesting to see the LRO pictures of the same area, with their higher resolution.
