Astronomers have discovered what they claim is the largest and farthest reservoir of water ever detected in the universe. Looking from a distance of 30 billion trillion miles away into a quasar, a team at California Institute of Technology has found a mass of water vapour that's at least 140 trillion times that of all the water in the world's oceans combined, and 100,000 times more massive than the sun.
Quasar is one of the brightest and most violent objects in the cosmos.
Because the quasar is so far away, its light has taken 12 billion years to reach Earth. The observations therefore reveal a time when the universe was just 1.6 billion years old, say the astronomers.
