Fast radio bursts (FRB)- one of the most mysterious signals from deep space. These little-studied outer space messages from distant stars and black holes, most often characterized by its unpredictability, jumping on the Universe for no apparent reason. As the portal sciencealert.comone of those incredible interstellar signals, scientists were able to detect 500 million light years from Earth. Repeating every 16 days, the alarm unwittingly makes us think of its artificial nature. Maybe our “brothers in mind” still found?
Radio signals aliens
Since the transfer of the first synthetic signal from the Ground has been more than 120 years. During this time, radio waves were able to successfully overcome the tens of millions of kilometers of space and be heard by representatives of some alien race, adjacent to the Land. However, no matter how much we aired into the Universe of radio and TV signals, no matter how much we send to space, special devices to search for aliens, we still never found someone who could share the lonely fate of mankind in the infinite Universe. Or found?
One of the most unexpected finds of the XXI century was the discovery of fast FRB of burst, which is repeated on a regular cycle every 16 days. The signal, named FRB 180916.J0158+65, actively playing for four days and then goes quiet for 12 days. After almost two weeks of absolute silence, a quick signal is repeated again.
Currently, the origin of the repetitive signal is not amenable to any attempts at a satisfactory explanation,it is known that fed-flashes are flashes of energetic radiation in the RF spectrum that do not last more than a few milliseconds. During this time they can emit as much energy as it can create hundreds of millions of stars, the size of the Sun.
Much to the surprise of the scientists involved in the study of FRB-flashes, the canadian collaboration of researchers CHIME announced the discovery at the end of 2019, another nine new powerful sources of interference, bringing the total number of such relays reached 10 sources FRB signals.
The discovery of the 16-day periodicity in the recurrent signal source can be an important key to understanding the nature of the unique object, the likes of which we haven’t seen in the observable Universe. Experts believe that the newly detected object may be very different from the familiar space of the formations that demonstrate the periodicity. In addition, the signal FRB 180916.J0158+65 is one of the few fast signals, whose place of origin was traced modern equipment. Thus, the signal source is located on the outskirts of a spiral galaxy 500 million light years from us.
In this case, what can be a repetitive signal from a distant galaxy? Scientists believe that the source of such a powerful radiation is unlikely to be an artificially created object, as flash FRB radiation is in the region of starburst, where future young stars. The most likely candidates for the title of a powerful source of radio signals may, in this case, Magnetar or black holes with stellar mass.
