Microscopic, metallic spheres were discovered during a 2023 oceanic expedition.
The BeLaU spherules are a collection of microscopic, metallic spheres enriched in beryllium (Be), lanthanum (La), and uranium (U), discovered during a 2023 oceanic expedition led by Harvard astrophysicist Avi Loeb. This mission aimed to locate remnants of a meteor, designated IM1, which entered Earth’s atmosphere in 2014 and was hypothesized to be of interstellar origin
Mystery at Blind Frog Ranch (Discovery Channel) visited the Serpent Mound in Ohio and were shown shatter cones from the meteorite impact that happened there.
Shatter cones are distinctive geological features that serve as compelling evidence of hypervelocity impact events, such as those caused by meteorites. They are cone-shaped, striated rock structures formed under extremely high pressures, typically exceeding 2 GPa (gigapascals), in the moments following an impact.
