A bug discovered deep in a goldmine and nicknamed “the bold traveller” has got astrobiologists buzzing with excitement. Its unique ability to live in complete isolation of any other living species suggests it could be the key to life on other planets.
A community of the bacteria Candidatus Desulforudis audaxviator has been discovered 2.8 kilometres beneath the surface of the Earth in fluid-filled cracks of the Mponeng goldmine in South Africa. Its 60°C home is completely isolated from the rest of the world, and devoid of light and oxygen.
