Low-temperature hydrothermal vents could survive on the dark ocean floors of moons like Jupiter's Europa for potentially billions of years, new computer simulations have shown, as astrobiologists strive to figure out whether these alien oceans could be habitable.
"The flow of water through low-temperature venting is equivalent, in terms of the amount of water being discharged, to all the rivers and streams on Earth, and is responsible for about a quarter of Earth's heat loss," said Andrew Fisher of the University of California, Santa Cruz , in aand Enceladus.
Applying this circulation model to Europa and Enceladus, the researchers altered properties such as gravity, temperature, the composition of the bedrock and how deep the water circulates, to better fit potential conditions on the ocean moons.
