A team of astronomers, including researchers from mit in the United States, caught repeated space signals related to fast radio bursts, the origin of which remains unknown. The source is designated as FRB 180916.J0158+65, removed from the Earth at 500 million light years. This was reported in an article published in the journal Nature.

FRB 180916.J0158+65 detected by the CHIME telescope in Canada, was the first source that produces a repetitive cycle of radio bursts. It emits radiation for four days, followed by a 12-day period of silence. He 16-day cycle was repeated for 500 days of observation. The source of the radio bursts is located on the outskirts of massive spiral galaxies.

According to scientists, repeated with such frequency the radio bursts are a new phenomenon in astrophysics. According to one of the assumptions, they may arise from compact object, for example, rotating and experiencing the precession of the neutron star. Another possibility is that the neutron star rotates around another neutron star or a black hole. Immediate source of radio waves approaches its companion, tidal forces which generate powerful flash. The third scenario assumes that the radio-emitting source rotates around the Central star, periodically emitting the gas cloud. When the object passes through the cloud, the latter acts as a lens and amplifies the radio waves.

The actual source of the FRB considers minitary is a special type of neutron star with an extremely strong magnetic field. Astronomers have noticed that these objects from time to time generate flare radiation, visible also in the radio.
