Astronomers using NASA’s Hubble Space Telescope have found that Markarian 231 (Mrk 231), the nearest galaxy to Earth that hosts a quasar, is powered by two central black holes furiously whirling about each other. http://www.nasa.gov/feature/goddard/hubble-finds-that-the-nearest-quasar-is-powered-by-a-double-black-hole |

Strange. I thought quasars looks like this. |

The binary black hole system should lose energy by emitting gravitationa waves, like a binary pulsar system. But it is too far away to detect them with our resent sensitivity. Maybe LISA could have detected them, but the project was abandoned by NASA. Now ESA is going to launch eLISA Pathfinder in November. Tullio |

Hubble telescope has just discovered a double black hole in a galaxy which hosts the nearest quasar. The two black holes orbit each other and will end by merging in a few hundred thousands years.
