Astronomers for the first time observed the moment when the ultra -massive black hole in the center of the distant galaxy spits a plasma stream of 1 light year at a speed of one third of the speed of light. Technically, this structure consists of two jets, each of which has a width of about 0.5 light year. The study is published in The Astrophysical Journal Letters, writes Space.

Astronomers for the first time became interested in the super -massive black hole in the center of the Galaxy 1es 1927+654 back in 2018. Then they first saw how the environment of the black hole became very bright in visible, ultraviolet and X -ray light. It was assumed that this was due to the appearance of a relativistic black hole jet. Then, for a long time, the black hole did not show activity, but last year, astronomers with the help of ground radio telescopes were able to observe in real time the birth of such a jet. They presented their results in a recent study.

Scientists saw the formation of a structure consisting of two jets of a black hole, the width of each of which is approximately 0.5 light years, and the total valley of the structure is 1 light year.

The supermassive black hole that shot two jets of matter into space has a mass 1.4 billion times that of the Sun.. And its native galaxy 1es 1927+654, in the center of which is a black hole, is located at a distance of about 270 million light years from us.

Astronomers are familiar with the relativistic jets of black holes that emerge from their poles at almost the speed of light.. Such jets can reach a length of 23 million light years. These structures are common in supermassive black holes that actively consume surrounding matter.. Part of matter that does not get into the black hole moves to its poles.

At these poles, powerful magnetic fields accelerate particles until they are launched into space in powerful jets. Although astronomers have observed many of these relativistic jets before, they have never before seen one erupt in real time.. Scientists believe that the eruption began earlier, but it was hidden by hot gas, which then dissipated.



This discovery could help astronomers better understand how the powerful jets of supermassive black holes initially develop..

As Focus already wrote, scientists have found that supermassive black holes are spinning faster than expected, and also that their formation occurs differently than expected.

Focus also wrote that physicists discovered chirping cosmic waves in an unexpected part of space. Scientists have discovered cosmic waves that sound like birds chirping, although they weren't expected to be found so far from Earth.
