NASA encuentra fosiles de bacterias extraterrestres en meteorito

Traducción desde buzzfeed.com

Estas bacterias fosilizadas no son contaminación terrestre sino vestigios fosilizados de organismos vivientes que vivieron en el cuerpo fuente de donde se desprendieron dichos meteoritos (como cometas, lunas u otros cuerpos celestes). El descubrimiento implica que la vida está en todas partes, y que la vida en la tierra pudo haber llegado desde otros planetas

Fossils of Cyanobacteria in CI1 Carbonaceous Meteorites
Richard B. Hoover, Ph.D. NASA/Marshall Space Flight Center

Dr. Hoover has discovered evidence of microfossils similar to Cyanobacteria, in freshly fractured slices of the interior surfaces of the Alais, Ivuna, and Orgueil CI1 carbonaceous meteorites. Based on Field Emission Scanning Electron Microscopy (FESEM) and other measures, Dr. Hoover has concluded they are indigenous to these meteors and are similar to trichomic cyanobacteria and other trichomic prokaryotes such as filamentous sulfur bacteria. He concludes these fossilized bacteria are not Earthly contaminants but are the fossilized remains of living organisms which lived in the parent bodies of these meteors, e.g. comets, moons, and other astral bodies. The implications are that life is everywhere, and that life on Earth may have come from other planets.

Members of the Scientific community were invited to analyze the results and to write critical commentaries or to speculate about the implications. These commentaries will be published on March 7 through March 10, 2011.
