Solving The Long-standing Mystery Surrounding The Evolution Of Galaxies
2014-07-08 03:29:57

[ 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...

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...

National Radio Astronomy Observatory Scientists recently upgraded the Atacama Large Millimeter/submillimeter Array (ALMA) by installing an ultraprecise atomic clock at ALMA’s Array Operations Site, home to the observatory’s supercomputing correlator. This upgrade will eventually allow ALMA to synchronize with a worldwide network of radio astronomy facilities collectively known as the Event Horizon Telescope (EHT). Once assembled, the EHT -- with ALMA as the largest and most...

redOrbit Staff & Wire Reports - Your Universe Online Astronomers using the NASA Fermi Gamma-ray Space Telescope to study what they thought were two different classes of black-hole-powered galaxies known as blazars now believe that they may be one and the same. [ Watch the Video: Blazars: Artist Conception ] “We can think of one blazar class as a gas-guzzling car and the other as an energy-efficient electric vehicle,” lead researcher and Clemson University astrophysicist Marco...

Illustris simulation
2014-05-08 05:17:50

redOrbit Staff & Wire Reports - Your Universe Online Researchers at MIT and Harvard have devised the most accurate model to date of how our universe first took shape. Dubbed Illustris, the new virtual cosmos covers the 13 billion-year evolution of the universe beginning just 12 million years after the Big Bang. It includes details never before achieved in a simulation, and accurately portrays the distribution and composition of numerous types of galaxies. "Until now, no single...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Most stars move around the galaxy in well-defined orbits, pulled under the influence of the Milky Way’s gravity. It is the predictable motion of the stars around the Milky Way’s supermassive black hole core that gives the galaxy its spiral structure. There are, of course, deviations from the norm, but on average the stars move at a leisurely pace of roughly 500,000 miles per hour. But this is not always the case. In...

April Flowers for redOrbit.com - Your Universe Online A new superpowered small black hole, called MQ1, has been discovered by a team of Australian and American astronomers who were studying nearby galaxy M83. MQ1 is the first object of its kind to be studied in this much detail. Previously, astronomers have found a few compact objects as powerful as MQ1, but they have been unable to calculate the size of the black hole contained within until now. Using multiple telescopes, the team's...

redOrbit Staff & Wire Reports - Your Universe Online Using NASA’s Chandra X-ray Observatory and a host of other telescopes, astronomers have managed to locate one of the most powerful black holes ever discovered – a gravity-intense region of space that is located nearly four billion light years from Earth and has prevented trillions of stars from forming. This black hole, which is located in a galaxy cluster known as RX J1532.9+3021 (or RX J1532 for short), has created gigantic...

Dead Star, Black Holes Highlighted In Dazzling NASA NuSTAR Imagery
2014-01-10 10:11:37

Gerard LeBlond for redorbit.com - Your Universe Online A pair of dazzling images from NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) highlights the observatory's impressive imaging capabilities for objects both near and far. The first image (featured above) is of the energized remains of a dead star, labeled the “Hand of God” for its formation resembling that of a hand. the second image (see below) is of distant black holes surrounded by a cloud of dust. NuSTAR’s...

ESA Releases Hubble Image Of Messier 83, A Galaxy With Two Hearts
2014-01-10 06:45:29

April Flowers for redOrbit.com - Your Universe Online A new image released from the ESA and NASA jointly-operated Hubble Space Telescope features the spiral galaxy Messier 83, also known as the Southern Pinwheel Galaxy. Messier 83, which is one of the largest and closest barred spiral galaxies to us, has hosted a large number of supernova explosions, and is thought to have a double nucleus at its core. The image was released this week at the 223rd meeting of the American Astrophysical...

Microquasar -- Microquasars are smaller cousins of quasars. They are named after quasars, as they have some common characteristics: strong and variable radio emission often seen as radio jets, and an accretion disk surrounding a black hole. In quasars, the black hole is supermassive (millions of solar masses) as in microquasars, the black hole mass is a few solar masses. In microquasars, the accreted mass comes from a normal star and the accretion disk is very luminous in optical regions...

Black Hole -- Black holes are objects so dense that not even light can escape their gravity. They are believed to form from the gravitational collapse of astronomical objects containing two or more solar masses. Astronomical observations suggest that the center of most galaxies, including our own Milky Way, contain supermassive black holes containing millions to billions of solar masses. Black holes are predictions of Einstein's theory of general relativity. In particular, they occur...
