Intermediate Mass Black Hole in M82
2014-08-18 04:11:35

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...

black hole growth
2014-08-12 07:56:18

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...

Trio Of Supermassive Black Holes Discovered In Distant Galaxy

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...

WASHINGTON, June 19, 2014 /PRNewswire-USNewswire/ -- An international team of astronomers, using data from several NASA and European Space Agency (ESA) space observatories, has discovered unexpected behavior from the supermassive black hole at the heart of the galaxy NGC 5548, located 244.6 million light-years from Earth. This behavior may provide new insights into how supermassive black holes interact with their host galaxies. http://photos.prnewswire.com/prnvar/20081007/38461LOGO...

Magnetic Fields Counteract The Forces Of Supermassive Black Holes
2014-06-05 11:37:47

Brett Smith for redOrbit.com - Your Universe Online A supermassive black hole sits at the center of most galaxies and a new study published in the journal Nature has found that super-powerful magnetic fields can have influence near and even counteract the forces of these black holes. "This paper for the first time systematically measures the strength of magnetic fields near black holes," said study author Alexander Tchekhovskoy, an astronomer at the University of California, Berkeley....

redOrbit Staff & Wire Reports - Your Universe Online A decades-old theory used by astronomers to explain the varying appearances of supermassive black holes is being called into question in the wake of new data obtained using NASA's Wide-field Infrared Survey Explorer (WISE), officials from the US space agency announced on Thursday. The unified theory of active, supermassive black holes was devised in the late 1970s to explain why black holes that are similar in many ways can have...

WASHINGTON, May 22, 2014 /PRNewswire-USNewswire/ -- A survey of more than 170,000 supermassive black holes, using NASA's Wide-field Infrared Survey Explorer (WISE), has astronomers reexamining a decades-old theory about the varying appearances of these interstellar objects. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The unified theory of active, supermassive black holes, first developed in the late 1970s, was created to explain why black holes, though similar in nature,...

elliptical galaxy M87
2014-04-30 12:25:17

Harvard-Smithsonian Center for Astrophysics The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time. "Astronomers have found runaway stars before, but this is the first time we've found a runaway star...

Pair Of Supermassive Black Holes Discovered By XMM-Newton
2014-04-22 14:09:30

ESA A pair of supermassive black holes in orbit around one another have been spotted by XMM-Newton. This is the first time such a pair have been seen in an ordinary galaxy. They were discovered because they ripped apart a star when the space observatory happened to be looking in their direction. Most massive galaxies in the Universe are thought to harbor at least one supermassive black hole at their center. Two supermassive black holes are the smoking gun that the galaxy has merged with...

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...

Seyfert Galaxy -- Seyfert galaxies are spiral or irregular galaxies containing an extremely bright nucleus, most likely caused by a supermassive black hole, that can sometimes outshine the surrounding galaxy. The light from the central nucleus varies in less than a year, which implies that the emitting region must be less than one light year across. They are named for the astronomer Carl Seyfert, who studied them extensively in the 1940s. They are a subclass of active galactic nuclei....

Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
