Record-breaking Binary found by NASA Telescope

An international team of scientists has found the first gamma-ray binary in a nearby galaxy and the most luminous one ever seen, using data from NASA's Fermi Gamma-ray Space Telescope.
●    The dual-star system, dubbed LMC P3, contains a massive star and a crushed stellar core that interact to produce a cyclic flood of gamma rays, the highest-energy form of light.
●    Fermi has detected only five of these systems in our own galaxy.
●    Gamma-ray binaries are prized because the gamma-ray output changes significantly during each orbit and sometimes over longer time scales
●    These rare systems contain either a neutron star or a black hole and radiate most of their energy in the form of gamma rays.
●    LMC P3 is the most luminous such system known in gamma rays, X-rays, radio waves and visible light, and it is only the second one discovered with Fermi.
