Early Universe Was Full Of Supermassive Black Holes
2012-10-08 12:41:21

Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered a new population of supermassive black holes in the early universe by using infrared surveys. After traveling 11 billion years, the light from supermassive black hole ULASJ1234+0907 reached Earth. This black hole has more than 10 billion times the mass of the Sun, and 10,000 times the mass of the supermassive black hole in our own Milky Way. The latest research, published in the journal Monthly Notices of...

Star Discovery Tests Einstein

Lee Rannals for redOrbit.com — Your Universe Online Astronomers, using the Keck Observatory, have found the star they need to test Einstein's theory about the fabric of space-time. UCLA astronomers said they have discovered a star that orbits the enormous black hole at the center of our Milky Way that will help discover whether Albert Einstein was right in his fundamental prediction of how black holes warp space and time. The star, S0-102, orbits the black hole every...

Messier 22 Has Two Black Holes
2012-10-03 12:49:09

Lee Rannals for redOrbit.com - Your Universe Online A surprising black hole discovery made while using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) is causing scientists to change what they know of globular star clusters. Astronomers used VLA to study the globular cluster known as Messier 22, which is a tight-knit collection of hundreds of thousands of stars that lie 10,000 light-years away from Earth. The team had hoped to find evidence for a rare type of...

Astronomers Describe Fireworks In The Early Universe
2012-09-27 19:28:13

Lee Rannals for redOrbit.com — Your Universe Online Astronomers suggest, in the Astrophysical Journal Letters, as galaxies formed in the early universe, they were accompanied by fireworks in the form of energy bursts. Active galaxies are easily detected due to their luminous radio, ultraviolet or X-ray radiation, which results from steady accretion onto their massive central black holes. Little has been known about the composition of these galaxies or their relationship to the...

NASA will host a news teleconference at 1 p.m. EDT, Wednesday, Aug. 29, to announce new discoveries from its Wide-field Infrared Survey Explorer (WISE). The discoveries are related to the distant universe, including supermassive black holes and rare galaxies. The briefing participants are: -- Daniel Stern, astronomer, NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif. -- Peter Eisenhardt, WISE project scientist, JPL -- Jingwen Wu, astronomer, JPL -- Rachel Somerville,...

Four Black Hole Candidates Discovered
2012-07-21 08:01:00

redOrbit Staff & Wire Reports - Your Universe Online Researchers from a Japanese university have discovered intermediate-mass black hole (IMBH) candidates at the center of the Milky Way, the National Astronomical Observatory of Japan (NAO) announced on Friday. Tomoharu Oka, an Associate Professor at Keio University, and colleagues used radio telescopes to locate four black hole candidates approximately 30,000 light-years from the solar system, located in the direction of the...

Black Holes Need Diet Rich In Stars To Grow

Lawrence LeBlond for redOrbit.com - Your Universe Online Researchers from several American institutes and agencies have developed a new model showing how an elusive type of black hole can be formed in the gas surrounding their supermassive counterparts. The scientists, from the American Museum of Natural History (AMNH), the City University of New York (CUNY), the Jet Propulsion Laboratory (JPL) of the California Institute of Technology (Caltech), and the Harvard-Smithsonian Center for...

Belching Black Hole
2012-07-09 11:03:28

Observations with CSIRO's Australia Telescope Compact Array have confirmed that astronomers have found the first known "middleweight" black hole. Outbursts of super-hot gas observed with a CSIRO radio telescope have clinched the identity of the first known "middleweight" black hole, Science Express reports online today. Called HLX-1 ("hyper-luminous X-ray source 1"), the black hole lies in a galaxy called ESO 243-49, about 300 million light-years away. Before it was found,...

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...

  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
