I've been waiting for a long time to finally post this paper. I co-authored a paper with Avi Loeb analyzing the samples we collected from the Pacific Ocean. We discovered spherules that appear to be from a different solar system due to their ultra high abundance of Beryllium, Lanthanum, and Uranium (thus BeLaU).
The paper should be online soon and we can't wait for the peer review process. We also have a fairly good idea where the large fragments landed for the next expedition, which will allow us to determine if the object was artificial or just part of another planet's core. Regardless, this result means we likey have the first extrasolar object ever recovered.
