Latest Supermassive black hole Stories
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.
NASA said on Wednesday that its Swift orbital telescope has captured a black hole ripping apart a star.
VV 340, also known as Arp 302, provides a textbook example of colliding galaxies seen in the early stages of their interaction.
WASHINGTON, July 27, 2011 /PRNewswire-USNewswire/ -- The flow of hot gas toward a black hole has been clearly imaged for the first time in X-rays.

NASA said on Wednesday that astronomers have found the first evidence that black holes were common in the early universe.
A study using NASA's Swift satellite and the Chandra X-ray Observatory has found a second supersized black hole at the heart of an unusual nearby galaxy already known to be sporting one.
WASHINGTON, May 20, 2011 /PRNewswire-USNewswire/ -- An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere, has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy.

An international team of scientists using data from NASA's Swift satellite confirms the existence of a largely unseen population of black-hole-powered galaxies.
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...
