The findings suggest that Enceladus possesses a hot, porous core that heats up the deepest water in its subsurface ocean to 90 degrees Celsius, a temperature not dissimilar to that found around the hydrothermal vents in some of Earth's deepest oceans."A hydrothermal system like this could fulfill the basic criteria to have life: that is energy, nutrients and liquid water," said Hsiang-Wen Hsu from the University of Colorado.

"But we don't know if the water was warm enough for long enough. If the temperature wasn't stable, life may not have happened there."
