Discovered the largest water mass in the universe

An international team of astronomers recently discovered a real "reservoir" of water in the universe that is 100,000 times the mass of the Sun. Water is about a distant quasar 12 billion light years.
This quasar (quasi-stellar radio source quasi-stellar radio source) or the cosmological source of electromagnetic radiation, is limited only by the amount of water that surrounds it, but also by the amount of energy emitted - it is equal to the energy emitted 1,000 billion Suns - comes from a supermassive black hole in the center of quasars.
Water is found in the gaseous state and is unusually hot and dense, so it caused quite a sensation among researchers, astronomers and scientists. "This discovery is so exciting," said one of the astronomers who discovered the quasar. "Not only do we find water in space so far, but it has enough to fill the oceans on Earth more than 100 billion times."
Most water in our galaxy is frozen and can be found only in certain regions, unlike the aforementioned water around quasars, which extends thousands of light years around.
The discovery was made spectrograph Z-Spec, which uses millimeter wavelength (between infrared and microwave rays), and is located in the Caltech Submillimeter Observatory in Hawaii. The spectrograph detectors are cooled to 0.06 degrees above absolute zero to allow for superior sensitivity required for such measurements.
This finding emphasizes the importance of millimeter or submilimeter frequency band for astronomy, which in the past two or three decades are increasingly used for observation. Astronomers are currently working on the construction of 25-meter telescope that will be placed in the Chilean Atacama desert. With its help, you will discover some of the earliest galaxies in the universe and measure the concentration of water and other gases. For example, the discovery of quasars away 12 billion light years will enable scientists because of the relatively slow speed of light to see how the universe looked like after 1.6 billion years since its inception.
