wow I didnt knew about this and it looks amazing!!!!
I dont know i have a feeling that is actually kind of debris, like a a part of a spaceship that was destroyed and this are the remains that entered into orbit.

The shape makes me think that probably it was kind of ripped of from a large housing in another big ship. I dont know but there were some pictures floating around the net some months ago about this space hulk in the moon partially buried, might this be a distress beacon of some sort?
