WASHINGTON, Aug. 18, 2014 /PRNewswire-USNewswire/ -- Astronomers have uncovered rhythmic pulsations from a rare type of black hole 12 million light-years away by sifting through archival data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The signals have helped astronomers identify an unusual midsize black hole called M82 X-1, which is the brightest X-ray source in a galaxy known as Messier 82. Most black holes...

redOrbit Staff & Wire Reports - Your Universe Online Astronomers from the University of Maryland and NASA’s Goddard Space Flight Center in Greenbelt, Maryland have accurately measured and confirmed the existence of a black hole roughly 400 times the mass of our sun. Black holes that range in size from about 10 to 100 times the mass of our sun are the remnants of dying stars, while much larger supermassive black holes are more than one million times our sun’s mass and typically...

University of Maryland and NASA astronomers used rhythmic flares of light to measure a brilliant object 12 million light years from Earth, confirming that it is a rare, mysterious intermediate-mass black hole. (PRWEB) August 17, 2014 The universe has so many black holes that it’s impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big, and colossal. Astronomers know that black...

April Flowers for redOrbit.com - Your Universe Online An extreme and rare event in the region of space immediately surrounding a supermassive black hole has been captured by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. The corona of the black hole, a compact source of X-rays that is situated nearby, has moved closer to the black hole over a period of just days. "The corona recently collapsed in toward the black hole, with the result that the black hole's intense gravity...

redOrbit Staff & Wire Reports - Your Universe Online Several processes typically limit how quickly black holes can grow, so how did those located at the ends of the universe come to have masses equal to several billion suns? Researchers from the Wiezmann Institute of Science and Yale University have proposed a potential solution in the latest edition of the journal Science. These enormous black holes, the study authors noted in a statement, consume large quantities of interstellar...

Solving The Long-standing Mystery Surrounding The Evolution Of Galaxies

[ Watch The Video: A Simulated Dwarf Galaxy 800 Million Years After The Big Bang ] The University of Sheffield New research by academics at the University of Sheffield has solved a long-standing mystery surrounding the evolution of galaxies, deepening our understanding of the future of the Milky Way. The supermassive black holes in the cores of some galaxies drive massive outflows of molecular hydrogen gas. As a result, most of the cold gas is expelled from the galaxies. Since...

Royal Astronomical Society (RAS) Astronomers investigating behavior of the universe shortly after the Big Bang have made a surprising discovery: the properties of the early universe are determined by the smallest galaxies. The team report their findings in a paper published today in the journal Monthly Notices of the Royal Astronomical Society. Shortly after the Big Bang, the universe was ionized: ordinary matter consisted of hydrogen with its positively charged protons stripped of...

Brett Smith for redOrbit.com - Your Universe Online According to astrophysicists, dark matter is the key to understanding the universe as it comprises 85 percent of all mass found in it and is suspected to have caused the growth of galaxies. In a new study to be presented at the Royal Astronomical Society's National Astronomy Meeting, scientists from that country’s Durham University have found a possible explanation for why some dark matter didn’t form galaxies in the early Universe...

Trio Of Supermassive Black Holes Discovered In Distant Galaxy
2014-06-26 08:58:10

Brett Smith for redOrbit.com - Your Universe Online While many galaxies have a supermassive black hole at their core, a new study published in the journal Nature has revealed a truly exotic phenomenon – a galaxy more than four billion light years away with three orbiting supermassive black holes at its center. The study authors said their work indicates that there could be numerous other galaxies with two or more black holes at their center. “What remains extraordinary to me is...

Stream Of Gas Observed Escaping Grasp Of Supermassive Black Hole
2014-06-20 10:53:54

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The classic image of black hole systems is the in-flowing gas being consumed by the singularity. However, black holes are far from simply being cosmic vacuum cleaners, and occasionally even exhibit some strange behavior. Recently, a team of astronomers found a clumpy stream of gas quickly flowing outward from the supermassive black hole at the core of the galaxy NGC 5548. This unusual phenomenon was discovered when a...

Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
