That was really interesting. The infinite density of mass aproaching the speed of light seems to be a black hole normal density. That is really an extreme rotation! Steve Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group. GPUUG Website |

Johnny I think you should respect a man that does know this stuff Tullio and worked in the field and is now retired When smart men talk you should listen |

“Our Galaxy’s black hole may be cooking its dinner right in front of Herschel’s eyes.†Supermassive black hole feasts on hot gas for dinner It’s not everyday that you get to see what’s on a black hole’s dinner menu. The European Space Agency’s Herschel space observatory has spotted hot molecular gas that may be circling or falling towards the supermassive black hole located at the center of our Milky Way galaxy. |

Interesting, Lynn:) Yes it is interesting, Julie, hope it stays 26,000 light-years away from earth. |

Interesting, Lynn:) +1 I am really enjoying the great links, and raw science. We may eventually end up with a Black Holes part 3. :D Steve Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group. GPUUG Website |

Huge one! Black Hole-Powered Jets Plow Into Galaxy This composite image of a galaxy illustrates how the intense gravity of a supermassive black hole can be tapped to generate immense power. The image contains X-ray data from NASA's Chandra X-ray Observatory (blue), optical light obtained with the Hubble Space Telescope (gold) and radio waves from the NSF’s Very Large Array (pink). This multi-wavelength view shows 4C+29.30, a galaxy located some 850 million light years from Earth. The radio emission comes from two jets of particles that are speeding at millions of miles per hour away from a supermassive black hole at the center of the galaxy. The estimated mass of the black hole is about 100 million times the mass of our Sun. The ends of the jets show larger areas of radio emission located outside the galaxy. |

Black Hole Naps Amidst Stellar Chaos Nearly a decade ago, NASA's Chandra X-ray Observatory caught signs of what appeared to be a black hole snacking on gas at the middle of the nearby Sculptor galaxy. Now, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), which sees higher-energy X-ray light, has taken a peek and found the black hole asleep. The Sculptor galaxy is seen in a new light, in this composite image from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Southern Observatory in Chile.

I think that to solve this problem was one of the purposes of the LISA gravitational wave detector based on three satellites, to detect the long wavelength/small frequency GWs generated in the Big Bang. The mission was abandoned by NASA for budgetary reasons and is carried on by the European Space Agency. The LISA Pathfinder mission should go in orbit in 2015 aboard the VEGA launcher just to test the experimental apparatus but the full LISA mission is still in doubt. Tullio |

ESA animation. As in a simulation such as this display? Black Hole Eats Star - NASA Simulation The simulations are useful tools to fill in the gaps in the extreme data that we can't see or directly detect. Simulations are also very useful experimental tools to test ideas and to test test-data. And the media love such stuff because it 'looks pretty'. The science and/or educational bits often get left behind... Such is the power of Hollywood? And then we have real scientific observation which is a complete turn-off to most people until you can realize what is being shown.

NASA's Chandra Turns Up Black Hole Bonanza in Galaxy Next Door Using data from NASA's Chandra X-ray Observatory, astronomers have discovered an unprecedented bonanza of black holes in the Andromeda Galaxy, one of the nearest galaxies to the Milky Way. Using more than 150 Chandra observations, spread over 13 years, researchers identified 26 black hole candidates, the largest number to date, in a galaxy outside our own. Many consider Andromeda to be a sister galaxy to the Milky Way. The two ultimately will collide, several billion years from now. ___________________ The universe wastes nothing, it's simply transferred. |
