Study Discovers How Massive Black Holes Grow So Rapidly
2012-03-25 04:42:56

Black holes that grow to masses billions of times greater than that of our sun most likely reached those sizes by consuming objects from multiple locations at the same time, researchers from the UK and Australia claim in a new study set for publication in the journal Monthly Notices of the Royal Astronomical Society. In a Friday press release, officials with the University of Leicester, who conducted the study along with colleagues from Australia's Monash University, compared the process...

Runaway Planets At 30 Million Miles Per Hour Possible
2012-03-22 13:27:20

Harvard-Smithsonian Center for Astrophysics researchers have determined that some planets are flying around in space at 30 million miles per hour. These hypervelocity planets are produced in the same way as the hypervelocity star that was found seven years ago traveling around the Milky Way Galaxy at 1.5 million miles per hour. "These warp-speed planets would be some of the fastest objects in our Galaxy," astrophysicist Avi Loeb of the Harvard-Smithsonian Center for Astrophysics said in...

Astronomers Clock Record Wind In Stellar-Mass Black Hole
2012-02-21 15:21:23

Astronomers have clocked the fastest wind yet ever discovered blowing off a disk around a stellar-mass black hole. The team used NASA's Chandra X-ray Observatory to discover that the wind at this black hole is moving about 20 million miles per hour, or about 3 percent of the speed of light. According to NASA, this is nearly 10 times faster than other winds that have been seen around other stellar-mass black holes. "This is like the cosmic equivalent of winds from a category five...

WASHINGTON, Feb. 21, 2012 /PRNewswire-USNewswire/ -- Astronomers using NASA's Chandra X-ray Observatory have clocked the fastest wind yet discovered blowing off a disk around a stellar-mass black hole. This result has important implications for understanding how this type of black hole behaves. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The record-breaking wind is moving about 20 million mph, or about 3 percent of the speed of light. This is nearly 10 times faster than...

Black Hole Found At The Center Of A Shredded Galaxy
2012-02-15 13:40:43

Astronomers say they have found a black hole that was once at the core of a now-disintegrated dwarf galaxy. The researchers used NASA's Hubble Space Telescope to find a cluster of young, blue stars encircling the first intermediate-mass black hole ever discovered. "For the first time, we have evidence on the environment, and thus the origin, of this middle-weight black hole," Mathieu Servility, who worked at the Harvard-Smithsonian Center for Astrophysics when this research was...

Scientists Get Ready To Image A Black Hole
2012-01-18 10:02:35

Astronomers are building a virtual telescope as big as our planet that will capture the first ever picture outlining an enormous black hole within our galaxy. The Event Horizon Telescope will be powerful enough to see all the way to the center of the Milky Way, where the super massive black hole lives. Researchers believe by capturing an image of the black hole, it will allow astrophysicists to put Einstein´s General Theory of Relativity to the test. Scientists from related fields...

Black Hole Imaged Gobbling Up Accretion Disc
2011-11-04 09:59:30

[ Watch the Video ] A team of scientists has used the NASA/ESA Hubble Space Telescope to observe a quasar accretion disc – a brightly glowing disc of matter that is slowly being sucked into its galaxy´s central black hole. Their study makes use of a novel technique that uses gravitational lensing to give an immense boost to the power of the telescope. The incredible precision of the method has allowed astronomers to directly measure the disc´s size and plot the temperature...

Image 1 - Suspects Exonerated In The Quenching Of Star Formation
2011-10-12 04:23:27

Supermassive black holes millions to billions times the mass of our Sun lie at the heart of most, maybe all large galaxies. Some of these power brilliantly luminous, rapidly growing objects called active galactic nuclei that gather and condense enormous quantities of dust, gas and stars. Because astronomers had seen these objects primarily in the oldest, most massive galaxies that glow with the red light of aging stars, many thought active galactic nuclei might help to bring an end to the...

Image 1 - New Black Hole Anatomy Revealed
2011-09-29 07:15:57

A fleet of spacecraft including ESA's XMM-Newton and Integral have shown unprecedented details close to a supermassive black hole. They reveal huge 'bullets' of gas being driven away from the 'gravitational monster'. The black hole that the team chose to study lies at the heart of the galaxy Markarian 509, 500 million light years away in space. This black hole is colossal, containing 300 million times the mass of the Sun and growing more massive every day as it continues to feed....

Chandra Discovers Nearest Pair Of Supermassive Black Holes
2011-09-01 06:13:01

  Astronomers using NASA's Chandra X-ray Observatory discovered the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way. Approximately 160 million light years from Earth, the pair is the nearest known such phenomenon. The black holes are located near the center of the spiral galaxy NGC 3393. Separated by only 490 light years, the black holes are likely the remnant of a merger of two galaxies of unequal mass a billion or more years ago. "If this...

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...
