A lot of beautiful observations of Supernova remnant 1987A give a precise idea of its structure and its evolution. The regular interpretations of the observations set that the large energy needed to explain the brightness of the pearl necklaces is provided by shock waves involving remnants of a first explosion and a wave produced by the observed explosion although the existence of this wave is discussed. We develop the alternative explanation of the necklaces by photoionization. Our main hypothesis is that the explosion of the blue supergiant progenitor produces two neutron stars and a central brilliant object, a linear system similar to those which were observed by Halton Arp. We suppose that these stars remains bright in extreme UV, to maintain the strong ionization of a bubble of hot hydrogen nearly transparent in far UV (defined as the range of Lyman frequencies of atomic hydrogen). Outside the bubbles, three shells containing atomic hydrogen generate resonant, superradiant scatterings at Lyman frequencies, in tangential competing modes. The superradiance cools the gas and absorbs strongly the radial far UV light, hiding the stars. The shells may be identified with the inner active shells found from light echoes.
