It goes by the nondescript label “ALH 84001” but is more generally known as the Alan Hills meteorite, the said hills being the place where it was found in Antarctica. Scientists stirred a huge debate in 1996 when they announced that this meteorite might contain evidence for microscopic fossils of Martian bacteria. Essentially what they said was they found evidence of life (or former life) in other worlds.
Since then more studies using a more advanced High Resolution Electron Microscopy not available then provided the new evidence bolstering the original claims. According to spaceflightnow.com, the carbonate discs and associated tiny magnetite crystals present inside the meteorite reveal information that lessen opposing theories as to why the finding should not be supported as biological in origin. These new findings were reported in the November issue of the respected journal Geochimica et Cosmochimica Acta, the journal of the Geochemical and Meteoritic Society. A scientist (who studies magnetite-related life forms here on Earth) who peer-reviewed the paper declared, “I think the paper is really excellent. I have no trouble with the paper”.
