The discovered space objects, called by the authors "strange radio circles", emitting exclusively in the radio range, have not yet found their explanation. However, a hypothesis and a mechanism associated with it were previously put forward, which is capable of emitting radiation in the radio range. In this case, the radiating region in the observation plane can be represented as circular. The hypothesis and mechanism relate to the origin of particles of one of the components of dark matter. They appeared as a result of the analysis of the process of the propagation of stellar radiation by outer space. This radiation cannot propagate indefinitely in space without interacting with anything, since the absence of interaction contradicts the philosophical principle of the interconnection of phenomena in Nature. Therefore, when radiation quanta move across the expanses of the Universe, there must be weak dissipative losses due to the interaction of electromagnetic quanta with thin levels of matter, which leads to redshifts in the emission spectra of galaxies. It was also suggested earlier that quanta losing energy, gradually shifting to the region of long waves, can, under certain conditions, pairwise combine into very light neutral Bose particles, which are a component of dark matter. These particles have spin 0, or spin 2 and a mass of 0.0013 eV and below. These particles will be characterized by their gravitational interaction, both among themselves and with galactic objects. Neutral Bose particles under the action of perturbations can decay into pairs of bound photons. Therefore, the perturbation of the medium of the supposed particles should lead to the appearance of microwave radiation. The destruction of the dark component into quanta explains, for example, the presence of powerful radio emission from active galactic nuclei (quasars, radio galaxies) and large variations in the intensity of microwave radiation at short time intervals, recorded by the ARCADE radiometer (NASA). Taking the hypothesis of the origin of the specified component of dark matter, one can explain the origin of the "strange radio circles". To do this, it is enough to assume that this dark component is organized into clouds of different lengths and densities. Especially far from active galactic zones, where there are no powerful streams of baryonic matter - plasma, gas, dust. For example, in the high galactic latitudes of the Milky Way. In this case, the appearance of shock waves in the center of the cloud will lead to the decay of particles and the emission of photons of the specified range. Objects such as these clouds cannot be observed in any other range of electromagnetic waves. Likewise, radio emission from small galaxies with increased density of dark matter in the halo can be observed, the particles of which can be destroyed by disturbances coming from the galactic core. After the complete emission of energy by the disturbing baryon component, only radiation from the destroyed particles of the dark component remains under the action of shock waves in its medium. The radiation from strange radio circles can serve as an indirect confirmation of the previously stated hypothesis about the origin of the dark matter component
