Life from space

"Richard Hoover, an astrobiologist at the US space agency's Marshall space flight centre in Alabama, said filaments and other structures in rare meteorites appear to be microscopic fossils of extraterrestrial beings that resemble algae known as cyanobacteria. Some of the features look similar to a giant bacterium called Titanospirillum velox, which has been collected from the Ebro delta waterway in Spain, according to a report on the findings.... Hoover, an expert on life in extreme environments, has reported similar structures in meteorites several times before. So far, none has been confirmed as the ancient remains of alien life.
But writing in the Journal of Cosmology, Hoover claims that the lack of nitrogen in the samples, which is essential for life on Earth, indicates they are the remains of extraterrestrial life forms that grew on the parent bodies of the meteorites when liquid water was present, long before the meteorites entered the Earth's atmosphere."
