Both celestial bodies are so close to each other that they appeared in the "Fall of the Spiral of Death". Palomar Observatory scientists have seen the strange death of big stars, that was a dual system of neutron stars. The birth of binary stars was first registered, writes the Chronicle.info with reference to Around the world
A huge star has evolved into a surprisingly weak supernova at the edge of a spiral galaxy that lies from Earth at a distance of 920 million light years. Astronomers believe that the dying star had an invisible companion who stole much of his matter before the explosion.
Because a new neutron star and its companion are too close together, they eventually fuse, scientists believe. The fusion of neutron stars causes waves in the space-time continuum called gravitational waves.
"We saw the explosion of a massive star, but a few incredibly powered plasma," explains study author Muncie Kasliwal. ̵
Astronomers believe the mass of the star was stolen by the accompanying compact star – a white dwarf, neutron star or black hole.
Supernova explosions – the source of heavy metals in the universe: gold, platinum, lead or Uranium.
