The Life on the Moon


Life has been found on our closest celestial neighbour at last- the moon. Of course, everybody knows this now however a recent, two-hundred page paper has told more about what this actually is. Discovered by the European Space Agency’s Lunar Dawn rover, it appears to be an entire ecosystem. It appears that a colony of Archaea has survived the near vacuum by turning the rock into oxygen through complex chemistry. They then gather nutrients, again from the rock, and release feed on this. Even more astounding, though, is the predators. Tardigrades have been found preying on the Archaea. This, however, may not be an example of convergent evolution. The life has been found inside a meteor crater, from a meteor of terrestrial origin. The tardigrades are thought to have stayed frozen inside the meteor until impact. However, good astrobiologists, do not give up hope! The fact that the tardigrades woke up means that there has to have been liquid water at some point in the lunar history!
