Aliens could be living in a giant sea.
Aliens could be hiding under the sea
Scientists have discovered the largest reservoir ever detected, which contains 140 trillion times the amount of all the water in Earth's oceans.
The experts at the California Institute of Technology are convinced that some form of extraterrestrial life could exist in the water but there is little chance of alien encounter as the reservoir is 12 billion light years away from our planet - meaning it would require a spaceship to travel at the speed of light for more than a decade just to reach it.
Matt Bradford, a scientist at NASA's Jet Propulsion Laboratory, said: "The environment around the quasar is unique in that it's producing this huge mass of water. It's another demonstration that water is pervasive throughout the universe."
