Two researchers from the University of Queensland (UQ) have confirmed that life existed on Mars. They first looked at magnetic crystals found in mud samples from a water trap of an Australian golf course. UQ News Online reports that they found their proof by comparing these crystals with those contained in a meteorite discovered in Antartica in 1984 and named ALH84001. "Our research shows that the structures found in the NASA meteorite were more than likely made by bacteria present on Mars four billion years ago, before life even started on Earth," said Dr Taylor, one of the two scientists. You'll find more details and references in this overview, both on the research work and the meteorite.
