Latest Black hole Stories
Astronomers have measured the mass of what may be the most massive black hole observed so far by using the Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory.
A team of scientists say they have detected the brightest flare ever observed in our galaxy's black hole.
Using an international version of LOFAR, called (ILT), a team of astronomers at ASTRON observed some very interesting black hole behavior: Namely, they’ve observed a black hole blowing a giant bubble of plasma.
A new stellar-mass black hole has been discovered in our galaxy by NASA's Swift satellite. High-energy X-rays emanating from a source towards the center of our Milky Way galaxy were observed, indicating the presence of a previously unknown black hole.
The center of the Milky Way seems like the last place to form a new planet, inhospitable and violent even. Stars crowd each other, whizzing through space like cars on a rush hour freeway while supernova explosions blast out shock waves and bathe the region in intense radiation.

Fueled by an intense burst of star formation, fierce galactic winds may blow gas right out of massive galaxies, which in turn could shut down their ability to make new stars.
Researchers from a Japanese university have discovered intermediate-mass black hole (IMBH) candidates at the center of the Milky Way.
According to a post by the European Research Media Center, the black hole in the center of our galaxy is about to meet up with a giant gas cloud in 2013.
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...
