‘Alien’ spherules dredged from the Pacific are probably just industrial pollution, new studies suggest

Microscopic metallic spheres recovered from the Pacific Ocean are likely the result of manmade industrial pollution — rather than pieces of an interstellar meteor — according to several new studies.

Last summer, Harvard astrophysicist and extraterrestrial hunter Avi Loeb declared that several tiny, metallic balls dredged up from the bottom of the ocean were likely remnants from an interstellar meteorite, and could even contain signatures of alien technology. Now, independent analysis suggests the spheres have a much less distant origin: They are more likely a by-product of burning coal on Earth.
