Microorganisms isolated in space

Indian and British researchers say they have successfully isolated microorganisms living in the upper atmosphere, as high as 40 km up. Whether the organisms originate on Earth or are “seeding” the planet from passing comets is the subject of some debate. “Contamination is always a possibility in such studies but the ‘internal logic’ of the findings points strongly to the organisms being isolated in space, at a height of 41km,” said one of the lead researchers. “Of course the results would have been more readily accepted and lauded by critics had we isolated novel organisms, or ones with NASA written on them! “
