S.E.T.I. doesn't seem like a legit or reliable source of info, the reporters just want to gain ratings, and the Vatican just wants to scare you to into believing God is your only salvation. I think they all have there own agenda on buying into this, the truth not being at the top of the list.
..And I've never heard of those places or sites either. Also, 240km is huge, I can see an asteroid floating around in space somewhere being that big, but not a ship.
It all seems like an interesting story, but I'm not buying any of it.
