Cloud 3-Times Mass of Earth and Rare Neutron Star Found in Orbit Around Milky Way's Supermassive Black Hole | |
| Anonymous Coward User ID: 5993120  United States04/08/2014 02:04 AM Report Abusive Post Report Copyright Violation | Cloud 3-Times Mass of Earth and Rare Neutron Star Found in Orbit Around Milky Way's Supermassive Black Hole Fascinating and disturbing. April 07, 2014 A cold gas cloud named G2, about three times the mass of Earth, will pass near Sgr A** in 2014 and already is being affected by tides from the black hole's powerful gravitational field. Astronomers expect G2 will swing so close to the black hole during the second quarter of the year that it will heat up to the point where it produces X-rays. Northwestern University's Daryl Haggard has been monitoring this little cloud and the Milky Way's central black hole, called Sgr A*, as part of a study that should eventually help solve the question : How exactly do black holes achieve supermassive proportions? "Sgr A* and the newly discovered magnetic neutron star, SGR J1745-29, which appears to be in orbit around the black hole, are dishing out lots of interesting science," Haggard said. "We've detected the brightest X-ray flare yet observed from Sgr A* and gathered data that are causing us to overhaul of our understanding of the neutron star population in the galactic center." The closest approach between the black hole and gas cloud is predicted to occur any day now. More: [link to www.dailygalaxy.com]  |

The doomed gas cloud, known as G2, is not the first to be consumed by black hole Sagittarius A* (or Sgr A*) but being able to observe the feast is a rarity, astronomers say. Daryl Haggard, an astronomer at Northwestern University, is studying G2 carefully in order to help solve solve a long-standing cosmological mystery: Just how do black holes attain supermassive proportions. [link to www.natureworldnews.com] Cloud suicide will wake black hole sleeping giant The sleeping giant at the centre of the Milky Way is about to wake up. A suicidal gas cloud is heading towards the galaxy's supermassive black hole, which will probably swallow the cloud, generating enormous flares of radiation that could help explain why the black hole is normally so placid. ----------------------------------------------- Genzel's colleague Stefan Gillessen spotted the cloud in images from the Very Large Telescope array in Chile, taken in March this year. It is an unusually dense cloud, not much bigger than our solar system and carrying about three times the mass of Earth. ------------------------------------------------- Unlucky timing That should send shockwaves through the cloud to heat it to several million degrees, and according to the group's simulations the gaseous collision will shred the cloud into filaments. This turmoil may mean that much of the cloud ends up swirling right down into the black hole. "By dumping more material in there, the cloud could drive the system into a higher efficiency regime," says Ginzel. There may be one huge flare of radiation or several over the coming decades.
