Latest Supermassive black hole Stories
WASHINGTON, Feb. 27, 2013 /PRNewswire-USNewswire/ -- Two X-ray space observatories, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency's XMM-Newton, have teamed up to measure definitively, for the first time, the spin rate of a black hole with a mass 2 million times that of our sun.

They are swallowers of light, destroyers of stars and the engines that drive our galaxies. Some believe they could even hold the key to interstellar travel and may perhaps...
redOrbit Staff & Wire Reports – Your Universe Online An unusually dense cloud located near the center of the galaxy does not appear to be forming any massive stars, astronomers at the California Institute of Technology (Caltech) have discovered, and that behavior has them puzzled as it appears to defy the rules of star formation. The cloud, which the researchers have named G0.253+0.016, is located in the vicinity of a supermassive black hole three millions times as massive as the...
redOrbit Staff & Wire Reports - Your Universe Online Using the airborne telescope on the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have learned that a series of recent starbursts had taken place in the central region of the Milky Way, NASA officials reported on Tuesday. According to the US space agency, our galaxy’s nucleus is home to a black hole with four million times the mass of the sun. It is orbited by a large disk of dust and gas, and holds...
WASHINGTON, Jan. 7, 2013 /PRNewswire-USNewswire/ -- NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, set its X-ray eyes on a spiral galaxy and caught the brilliant glow of two black holes lurking inside.

April Flowers for redOrbit.com - Your Universe Online It would be a mistake to think of black holes as having a uniformity of size or mass. They range from modest objects formed from the end of an individual stars' life to behemoths billions of times more massive that rule the centers of galaxies. A new study recently published in the journal Science, however, shows that high-speed jets launched from active black holes share fundamental similarities despite the mass, age or...

April Flowers for redOrbit.com - Your Universe Online NASA's Chandra X-ray Observatory has detected a jet of X-rays from a supermassive black hole 12.4 billion light years from Earth, making it the most distant X-ray jet ever observed. The jet gives astronomers a glimpse into the explosive activity associated with super massive black hole growth in the early universe. A quasar named GB 1428+4217, or GB 1428 for short, produced the jet of X-rays. The black holes at the center of most...
Lee Rannals for redOrbit.com – Your Universe Online A team of astronomers has grabbed an image of a huge elliptical galaxy with a core that is bigger than any seen before. The team used the Hubble Space Telescope to collect the image of the galaxy, which is about ten times the diameter of the Milky Way galaxy. The galaxy is a member of a class of galaxies with an unusually diffuse core filled without a concentrated peak of light around a central black hole. Viewing the core would...
Lee Rannals for redOrbit.com – Your Universe Online An international team of astronomers was able to measure the radius of a black hole for the first time. Researchers measured the radius of a black hole at the center of the galaxy M87, which lies about 50 million light-years away from the Milky Way. M87 has a black hole 6 billion times more massive than the Sun, and the team was able to observe the glow of matter near the edge of the black hole, or the "event horizon," using radio...
Latest Supermassive black hole Reference Libraries
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...
