Jupiter’s moon Europa may host life.

Jupiter’s icy moon Europa may host life in an ocean of liquid water hidden under its 10 kilometre-deep ice crust, scientists say.
Researchers from the University of Sao Paulo (USP) in Brazil conducted a theoretical research to evaluate microbial habitability of Europa using data collected from similar environments on the Earth.
In the Mponeng gold mine near Johannesburg, South Africa, at a depth of 2.8 km, researchers not only found traces of major changes linked to history of life on Earth, but also a terrestrial context similar to Europa.
It was recently discovered that the bacterium Candidatus Desulforudis audaxviator survives inside the mine without sunlight by means of water radiolysis, the dissociation of water molecules by ionising radiation.
According to the researchers, the environment colonised by bacteria in the Mponeng mine is an excellent analogue of the environment assumed to exist at the bottom of Europa’s ocean.
