The Biggest Water Reservoir In The Universe Floats Around A Black Hole

In 2011, astronomers discovered an enormous reservoir of water vapor more than 12 billion light-years from Earth. It is by far the largest (and most distant) collection of water ever found, containing 140 trillion times the amount of water in our planet's oceans. The vapor is circling a quasar powered by a black hole, and, because of its staggering distance, proves that water vapor was present in the universe's early stages.
