Black Hole P13
2014-10-09 06:58:43

April Flowers for redOrbit.com - Your Universe Online Approximately 12 million light years from Earth is a galaxy called NGC 7793, and just on the outskirts of this galaxy is a black hole, designated P13. P13 is a hungry black hole, consuming gas from a nearby star about ten times faster than astronomers believed possible before recent observations from the International Center for Radio Astronomy Research (ICRAR). The findings, published in a recent issue of Nature, reveal that P13 "is...

Linda Vu, Berkeley Lab Computing Sciences Findings made possible with NERSC resources and Berkeley Lab Code Certain primordial stars—those between 55,000 and 56,000 times the mass of our Sun, or solar masses—may have died unusually. In death, these objects—among the Universe’s first-generation of stars—would have exploded as supernovae and burned completely, leaving no remnant black hole behind. Astrophysicists at the University of California, Santa Cruz (UCSC) and the...

WASHINGTON, Sept. 17, 2014 /PRNewswire-USNewswire/ -- Astronomers using data from NASA's Hubble Space Telescope and ground observation have found an unlikely object in an improbable place -- a monster black hole lurking inside one of the tiniest galaxies ever known. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The black hole is five times the mass of the one at the center of our Milky Way galaxy. It is inside one of the densest galaxies known to date -- the M60-UCD1 dwarf...

Why Are Milky Way-like Galaxies Are So Common In The Universe?

ESO New observations explain why Milky Way-like galaxies are so common in the Universe An international research group led by Junko Ueda, a Japan Society for the Promotion of Science postdoctoral fellow, has made surprising observations that most galaxy collisions in the nearby Universe — within 40 million light-years from Earth — result in so-called disc galaxies. Disc galaxies — including spiral galaxies like the Milky Way and lenticular galaxies — are defined by...

Yue Shen, Carnegie Institution Quasars are supermassive black holes that live at the center of distant massive galaxies. They shine as the most luminous beacons in the sky across the entire electromagnetic spectrum by rapidly accreting matter into their gravitationally inescapable centers. New work from Carnegie’s Hubble Fellow Yue Shen and Luis Ho of the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University solves a quasar mystery that astronomers have been puzzling...

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...

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...
