Largest Water Reservoir In Universe, 12 billion Years In Past



What kind of aliens would evolve out of a light years wide mass of water vapor? That question could be posed knowing that 12 billion years in the past more water then exists on all of earth was floating out there in space.
Using a pair of sub-millimeter wavelength telescopes, two teams of astronomers have discovered the largest reservoir of water ever found in the Universe. The water-containing cloud was found near quasar APM 08279+5255, some 12 billion light years from Earth; this means that the radiation seen today from this quasar was emitted when the universe was a scant 1.6 billion years old. Calculations have placed the mass of water vapor in the cloud at approximately 100,000 solar masses, or 140 trillion times the mass of all water on the planet Earth.
