The vast oceans of liquid water believed to exist beneath the ice on Europa may be deeper than thought.
Jupiter's moon Europa has long been one of the most tantalizing bodies in the solar system, a world completely covered in a crust of ice it is thought that a vast ocean of liquid water may exist beneath its surface. To explore this alien sea it would be necessary to not only land a probe on the surface but for it to melt its way down through the ice to reach the water underneath. But how far down would it have to go ? Scientists now believe the water to be far deeper underground than previously thought.
"A global water ocean may be present, but relatively deep below the surface - around 25 to 50 kilometers," said Klára Kalousová. "There could be areas of liquid water at much shallower depths, say around 5 kilometers, but these would only exist for a few tens of thousands of years before migrating downwards."
"Here on Earth, life thrives wherever liquid water is found."
