Latest Black hole Stories
Whether on their own or orbiting as a pair, black holes donâ€™t typically sit still.
ESAâ€™s Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein.
According to new research, the flash from one of the biggest and brightest bangs ever recorded by astronomers is derived from a massive black hole at the center of a distant galaxy.
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.

WASHINGTON, April 7, 2011 /PRNewswire-USNewswire/ -- A new supercomputer simulation shows the collision of two neutron stars can naturally produce the magnetic structures thought to power the high-speed particle jets associated with short gamma-ray bursts (GRBs).

ESAâ€™s Integral gamma-ray observatory has spotted extremely hot matter just a millisecond before it plunges into the oblivion of a black hole, but is it really doomed?
When two galaxies merge to form a giant, the central supermassive black hole in the new galaxy develops an insatiable appetite.
X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...
Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...
Cygnus X-1 -- Cygnus X-1 (often abbreviated to Cyg X-1) is an X-ray source in the Cygnus constellation considered to be one of the most likely black hole candidates. The optical counterpart (HDE 226868) is a variable 8.9 magnitude star (visible with good binoculars in good observing conditions.) at right ascension 19 h 56.5 min and declination of 35 deg 4 min (for 1950 epoch). Cyg X-1 is a binary star that contains a O9-B0 supergiant (with a surface temperature of 31000 Kelvin) and a...
