Galactic center (in the latter case its energy density should be very high). Because similar signals have never been detected from the cosmos, GCRT J1745-3009 may either belong to a new class of radio sources or be yet another mode of activity of already known objects. The radio pulses might have been generated by a brown dwarf, but their characteristics are strongly different from those of the radio emission from brown dwarfs; besides, the periodicity of the pulses is hard to explain in this scenario. Another hypothesis is that the radio bursts had their origin in a magnetar, a neutron star with a strongmagnetic field, and that the 77-min time interval is the orbital period of a black hole binary star system.
