http://www.sciencealert.com/nasa-ha...t-gamma-ray-star-system-outside-the-milky-way NASA has discovered the first gamma-ray star system outside the Milky Way The brightest ever found. An international team of scientists has found the brightest gamma-ray binary ever seen, and it's the first to be seen outside the Milky Way galaxy. The team combined data from NASA's Fermi Gamma-ray Space Telescope with those from other facilities and confirmed that what was once thought to be a high-mass X-ray binary (HMXB)was in fact, a gamma-ray binary system. Their findings have been published in The Astrophysical Journal. The newly found gamma-ray binary, named LMC P3, was discovered in a small nearby galaxy called the Large Magellanic Cloud (LMC), located 163,000 light-years away. Gamma-ray binaries are systems wherein there are two stars, one orbiting the other. One is usually a massive star and the other is either a black hole or a neutron star (an extremely magnetic star), and are very rare, with only five found in our galaxy to date. And so far, LMC P3 is the most luminous gamma-ray binary system ever found in terms of gamma rays, X-rays, radio waves, and visible light. MORE...............
And no pesky life forms around that system to dirty things up. A germophobe's idea of squeaky clean. A good place to visit in a massively thick lead spaceship at a considerable distance. Artificial life forms would no doubt love it for the rad hard goodness and spectral purity. The perfect place to set up an orbiting ultra-clean manufacturing facility.
