An international team of researchers led by astrobiologist Tetyana Milojevic from the University of Vienna investigated a specific type of ancient bacteria that are known to flourish on extraterrestrial meteorites. By investigating a meteorite that included traces of this bacteria, the team discovered that these bacteria prefer to feed on meteors, a find which could provide insight into how life developed on Earth. Their studies verify the capacity of M. sedula to achieve the biotransformation of meteorite minerals, unwind microbial fingerprints left on the meteorite body, and provide the next step towards the knowledge of meteorite biogeochemistry.
