Largest and the oldest water body ever found in the universe

About 71 percent of  Earth is covered with water which is a big amount. But talking about space and universe it is not a big deal. Two teams of astronomers have discovered the largest and the farthest  water reservoir ever detected in the universe. The water reservoir is equivalent to 140 trillion times of all the water in the Earth's ocean. However because most of the Milky Way's water is in the form of ice, the amount of water in the water body is 4,000 times more water than our milky way galaxy.The reservoir surrounds a huge feeding black hole more than 12 billion light year away. The water body is surrounds a quasar(quasi stellar radio source) powered by a black hole which steadily consumes a surrounding disk of dust and gas.

     

                       Quasars are the most luminous, energetic and powerful known entities in space powered by a black hole which can emit 1,000 trillion times more energy than our sun and 65,000 times the energy of our milky way galaxy. Both group of astronomers studied the particular qusar (APM  08279-5255) which is emitting energy from the black hole which is 20 billion times more massive than the sun and produces energy as much as thousand trillion suns. As the black hole eats the disk, quasar emits an enormous amount of energy. The environment around the quasar is very unique that it is producing this huge mass of water. According to astronomer Alberto Bolatto, the light we are seeing left this quasar more than 12 billion years ago ,  we are seeing the water that was present 1.6 billion years after the beginning of the universe. The oldest known water body ever in our universe history.

                        The water vapour is an important trace that reveals the nature of quasar. In this quasar the water is distributed around the black hole in a gaseous region extended  hundreds of light year in size( 1 light year is about 6 trillion miles). There is a plenty amount of water vapor and other molecules present in the disk that surrounds the quasar which is enough to feed the black hole upto 6 times of its size. But it is not clear that it will happen or not. Astronomers say, since most of the gas may end up condensing into stars or may be ejected from quasar. The discovery was a part of quasar study commenced by NASA in 2008. Instrument called "Z spec"and CARMA were used. Z spec is a 10 meter long telescope.
