Astronomers have found what appear to betwo of the earliest and most primitive known supermassive black holes. The discovery, based largely on space telescope observationsSpitzerfrom NASA, will provide a better understanding of the origins of the universe, and how more primitive black holes, galaxies and stars were formed.
“We have found what is probablythe first generation of quasars, born in a dust-free environment and in the early stages of the evolution of the cosmos “, explained Jiang Linhua, from the University of Arizona (USA).
Black holes are huge distortions of space and time. The most massive and active lurk in the cores of galaxies, often surrounded by “donut” shaped structures of gas and dust, feeding and sustaining a growing black hole. Although today the universe could be described as “dirty and disheveled”, scientists believe that the early universe was not dusty. But no one had seen“unsullied” quasarsup to now.Spitzerhas identified two located approximately13 million light years distant from Earth, who have been baptizedJ00050006YJ0303-0019. Each quasar is driven by a supermassive black hole that weighs more than 100 million suns.
“We believe that these early black holes formed less than1 billion years after the Big Bang“explain the scientists.” The primordial universe did not contain any molecules that could coagulate to form dust; the elements necessary for this process were produced later and were pumped later by the stars. “
