11 July 1997 Nanobacteria are alive on Earth as well as Mars

Nannobacteria are minute spherical to worm-shaped cells (diameter 0.03 to 0.2 micrometers ) that participate in the formation of carbonates, clays, and other minerals on Earth. The supposed nannobacterial objects found by the National Aeronautics and Space Administration in the Martian meteorite can be exactly duplicated as to morphology and size by earthly examples. Grapelike colonies of 0.05-micrometers carbon balls in the Allende meteorite also resemble nannobacterial colonies in south Italian volcanic clays.
