Latest Stellar black hole Stories
Astronomers use infrared "eyes" to shed light on black holes.
Combining observations made with ESOâ€™s Very Large Telescope and NASAâ€™s Chandra X-ray telescope, astronomers have uncovered the most powerful pair of jets ever seen from a stellar black hole.
New evidence from NASA's Chandra X-ray Observatory and ESA's XMM-Newton strengthens the case that two mid-sized black holes exist close to the center of a nearby starburst galaxy.
Astronomers using ESOâ€™s Very Large Telescope have detected, in another galaxy, a stellar-mass black hole much farther away than any other previously known.
GREENBELT, Md., Nov. 10 /PRNewswire-USNewswire/ -- While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by.
While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by.
An international team of astronomers using the European Space Agency's XMM-Newton X-ray observatory says it's discovered a new kind of black hole. The scientists, led by Sean Farrell of the University of Leicester, England, said the newly found black hole weighs more than 500 solar masses and is a missing link between lighter stellar-mass and heavier super-massive black holes. Stellar-mass black holes about 3 to 20 times as massive as the sun, and super-massive black holes several million to...
Scientists have discovered a new class of black hole that stands at a mass of more than 500 times that of the Sun.
New results from NASA's Chandra X-ray Observatory have made a major advance in explaining how a special class of black holes may shut off the high-speed jets they produce.
The biggest black holes may feed just like the smallest ones, according to data from NASAâ€™s Chandra X-ray Observatory and ground-based telescopes.
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...
