The US space agency NASA has published a photo of a powerful jet of energy erupting from the jets of one of the massive black holes of the binary system 4U1630-47. The photo was taken during the study, which opened up new details of the composition of black holes.
This image was taken while researching the 4U1630-47 binary system using the CSIRO compact arrays of the Australia Telescope Compact Array Observatory in Eastern Australia and the XMM-Newton X-ray telescope in near-earth orbit of the European Space Agency. And although the star system 4U1630-47, as scientists believe, contains only a small black hole - several times larger than the mass of our Sun - the consequences of such eruptions can be significant.
In the course of the study, scientists established that jets (jets) emanating from black holes, consist not only of electrons and protons, but also of nuclei of heavy elements, such as iron and nickel, reports nasa.gov.
One of the co-authors of the study, James Miller-Jones of Curtin University (formerly Curtin University of Technology) at the International Center for Radio Astronomy in Western Australia, believes that traces of nickel and iron found in jets give astronomers a reason to say that the speed of movement of particles in these jets is extremely high and is about 0.67 the speed of light. “This is the first time that heavy nuclei were found in jets of a massive black hole,” adds the scientist.
In general, black holes are very “picky eaters” - tired of absorbing material emanating from stars, they reject surplus, releasing “steam”, as a rule, with two powerful jets (jets), as a result of which a black hole, freeing up free space inside, can continue to absorb cosmic material. The main mass of the cosmic material, approaching a black hole, ends its existence by erupting from a star system in the form of powerful jets emanating from two opposite poles of a rotating black hole.
According to scientists' assumptions, at least one large (heavy) black hole forms within the majority of galaxies during the compression of large stars. After compression, such stars create such a strong gravitational pull that no other substance (even light) can leave them anymore.
It should be noted that the black hole itself is a fairly compact object (by cosmic standards), in which a huge mass of various stellar matter is brought together. Actually, the physical characteristics of black holes, as well as their contents, in fact, are still completely unknown to science, and scientists have yet to figure out the only true reason for their occurrence.
