Our universe may have emerged from a black hole in a higher-dimensional universe, propose a trio of Perimeter Institute researchers in the cover story of the latest Scientific American.

Stream Of Gas Observed Escaping Grasp Of Supermassive Black Hole

The classic image of black hole systems is the in-flowing gas being consumed by the singularity. However, black holes are far from simply being cosmic vacuum cleaners, and occasionally even exhibit some strange behavior.

Magnetic Fields Counteract The Forces Of Supermassive Black Holes

A new study published in the journal Nature has found that super-powerful magnetic fields can have influence near and even counteract the forces of supermassive black holes.

A decades-old theory used by astronomers to explain the varying appearances of supermassive black holes is being called into question in the wake of new data obtained using NASA's Wide-field Infrared Survey Explorer.

A Stellar Explosion On The Outer Reaches Of The Universe Provides Clues About The Formation Of Black Holes
2014-05-08 03:10:01

On 24 October 2012 observatories across the world were alerted about a huge stellar explosion, the GRB121024A, which had been located just hours before in the Eridanus constellation by NASA's Swift satellite.

Illustris simulation

Researchers at MIT and Harvard have devised the most accurate model to date of how our universe first took shape. Dubbed Illustris, the new virtual cosmos covers the 13 billion-year evolution of the universe beginning just 12 million years after the Big Bang.

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...
