The modern concept of black holes is basedon models developed in ground research centers. However, the observation of these objects using space observatories provides a huge amount of unique information that can completely change the understanding of the nature of education and the life cycle of a black hole.
Currently, black holes are classifiedhow weak and strong. The latter have a huge mass, attract a huge amount of substance to themselves, which forms a bright accretion disk. Weak black holes, according to the model, cannot have accretion circles, since a little matter accumulates around them. However, these studies of the black hole from the galaxy NGC 3147, obtained by the Hubble space telescope, will force astronomers to reconsider the theoretical basis for the formation of the world view regarding black holes.
Relatively small NGC 3147, located in130 million light-years from Earth, has a mass of 250 million suns and was counted among the weak black holes in the study of traditional telescopes. However, when NGC 3147 fell into the field of view of the Hubble Space Telescope, it turned out that there was a pronounced, albeit dim accretion disk around the black hole. A faint glow transforms NGC 3147 into a small quasar. The structure of this accretion disk is exactly the same as that of the disks accompanying strong black holes. The difference lies only in the size and strength of the glow, which is hundreds of thousands of times weaker than that of “normal” accretion disks.
In such a disk, refuting modernideas about the nature of black holes, matter is very close to the center of the hole, and it is dispersed at a speed of 0.1 of the speed of light. Due to the high mass of BH, exceeding the solar a 250 million times, the outgoing light of the radiation is shifted to the red part of the spectrum. The information obtained will force scientists to revise some of the usual provisions of modern models of gas dynamics and develop new models to explain the nature of black holes. In the meantime, astronomers have called NGC 3147 "a quasar in miniature," since the light of the object being studied is characteristic of "gravitational monsters" of much brighter and larger galaxies.
