The Harvard astronomer discovered the objects on the sea floor while searching for pieces of an interstellar meteorite.
Back in June of 2023, Loeb - who had been on an expedition to search for pieces of a potentially artificially constructed interstellar object that fell somewhere in the Pacific Ocean - published a blog article describing the discovery of mysterious metal spherules with a composition he claimed to be "anomalous" when compared to human-made alloys.
"We found ten spherules," he said. "These are almost perfect spheres, or metallic marbles. When you look at them through a microscope, they look very distinct from the background."
"It has material strength that is tougher than all space rock that were seen before."
At the time, his claims were universally panned by scientists who ultimately concluded that what he had found was likely to be little more than - as University of Chicago physicist Patricio A Gallardo described it - "coal fly ash, a waste product of the combustion of coal in power plants and steam engines."
Not content with this explanation, Loeb is now back once again with new findings that he claims debunks this particular interpretation and again points toward extraterrestrial origins.
"What we did is compare 55 elements from the periodic table in coal ash to those special spherules that we found," he said. "And it's clearly very different."
"It's not based on opinions. And, of course, if you're not part of this scientific process and you are jealous of the attention that it gets, then you can raise a lot of criticism."
The Harvard astronomer also maintains that more should be done to track and study other nearby objects that could have come from distant solar systems.
"The best approach to figure it out is actually to do the scientific work of building observatories that look out and check what these objects are," he said.
"And if they happen to be birds, or airplanes, or Chinese balloons, so be it. We can move on after that. But we need to figure it out, it's our civil duty as scientists."
