"Revisiting Extraterrestrial Claims: New Findings on Interstellar Signals and Alien Debris"
A recent study suggesting the discovery of interstellar material on the ocean seabed has been challenged by a new study, which found that the iron isotopes of the spherules in question indicate a local origin, likely from the Australasian tektite strewn field caused by a large impact 790,000 years ago. While these particular spherules have a local origin, the search for interstellar objects on Earth continues.
