The study’s sole author, Richard Hoover of NASA’s Marshall Space Flight Center in Huntsville, Ala., describes filament-shaped structures he found in freshly fractured slices of the Ivuna, Orgueil and Alais meteorites. He concludes that these structures resemble the remains of single-celled cyanobacteria, which live in water and convert sunlight into food. According to the study, his chemical analysis suggests that the putative fossils are most likely from bacteria that grew while in space rather than terrestrial contaminants that infiltrated the rocks after they fell to Earth.
