I am fully, 100 percent confident that they have no idea. But then, how could they? What they are trying to do is figure out how spaghetti was made by looking through a telescope from 5 miles away at a bowl made last month, without knowing what spaghetti is supposed to be. This was the equivalent of sending a drone over to look, where they discover that it looks different from up close than it does from a long ways off. While this is a start, nobody's really going to know until we can stand on it with a full set of a analysis tools on hand.
