Jupiter's icy moon may host life in its oceans: Study

Jupiter's moon Europa may host life in an ocean of liquid water under its 10-kilometre-thick ice crust, suggested Brazilian researchers. The team based their claims on a bacterium that survives deep underwater without sunlight in environments similar to Europa. The bacterium in 2.8-km-deep South African mines was found to synthesise its energy from rock sulphates, formed via ionising radiation.
