Latest Stellar black hole Stories
Black holes are very efficient eating machines… They can double their mass in less than a billion years. That may seem long by human standards, but over the history of the Galaxy it's pretty fast.
Black holes that grow to masses billions of times greater than that of our sun most likely reached those sizes by consuming objects from multiple locations at the same time.
Astronomers have clocked the fastest wind yet ever discovered blowing off a disk around a stellar-mass black hole.
For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull.
Astronomers using NASA's Wide-field Infrared Survey Explorer (WISE) have captured rare data of a flaring black hole, revealing new details about these powerful objects and their blazing jets.
Using two NASA X-ray satellites, astronomers have discovered what drives the "heartbeats" seen in the light from an unusual black hole system.
Team led by University of Leicester confirm presence of ultra-bright object in nearby galaxy.
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...
