We did it. I led a Galileo Project expedition to the Pacific Ocean to retrieve spherules of the first recognized interstellar meteor, IM1, and brought back to Harvard College Observatory more than 50 that lay on the deep ocean floor for nearly a decade.
These sub-millimeter-sized spheres, which appear under a microscope as beautiful metallic marbles, were concentrated along the expected path of IM1, about 85 kilometers off the coast of Manus Island in Papua New Guinea.
