SPACE LIFE in METEORITES?

    On Friday, March 22 Alexei Rozanov, a corresponding member of the Russian Academy of Science, delivered a talk on space microorganism traces possibly found in meteorites. Everybody seems to remember the "Science" hit, the paper of American astrophysicists on microorganisms which are likely to have been found in "Martian" meteorites discovered in Antarctic. It was about strange oblong structures, some tens of nanometres in size. This paper, on the one hand, initiated American administrators in investments into the projects aimed at researching Mars and, on the other hand, was criticized vigorously by colleagues. First, nobody could justify those meteorites having arrived from Mars, second, they were too small to infer conclusions about them. Nearly at the same time Rozanov's team had an article being under inquiry in the editorial board of "Geohimia" (Geochemistry) magazine (Zhmur S.I., Rozanov A.Yu., Gorlenko V.M., Litified remnants of microorganisms in carbonaceous hondrites, Geohimia, 1997, V.1b, pp.66-68 (in Russian)). The paper told about discovering "gigantic" (compared with American ones) bacteria fossils in carbonaceous hondrites.

    The story with microorganisms in meteorites is likely to have begun much earlier than it was mentioned in the review by Rozanov's team (reprinted here from the "Paleontologia" magazine (in Russian)). Early researchers, however, did not apply but poor microscopes and chemical methods while investigating them. It is for the first time that Rozanov's team applied powerful electronic microscopes for the inquiry and discovered strange bacteria-like formations similar to those you can see in the picture ("Yefremovka" meteorite).

    I can hardly ever judge how reliable are identifications of these structures with bacteria. I think, professional geochemists and biologists can do it better. Nonthelees, the number and size of "life" traces found in meteorites are strikingly impressive. Now Alexei Rozanov is working in tight collaboration with his NASA colleagues.
