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...

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...
