I agree, it is most likely the ark, the "master" control for the Halos. I believe this is why the Covenant captured Keyes in the first place, because they knew the ark was on Earth. So they found it, ravaged it, and now they finally found what they were lokking for. So it seems, "this is the way the world ends."
