NuSTAR Observes Dormant Black Hole In Nearby Sculptor Galaxy
2013-06-12 08:35:23

NASA’s Chandra X-ray Observatory caught signs of what appeared to be a black hole eating gas at the middle of the nearby Sculptor galaxy nearly a decade ago. A new observation by NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has found the black hole asleep.

Astronomers Catch Supermassive Black Hole Devouring Distant Star
2012-05-02 14:24:52

Astronomers have for the very first time captured a supermassive black hole devouring a wandering star that strayed too close to a phenomena that nothing can escape, not even light.

Chandra Reveals Outburst From Old Black Holes
2012-04-30 14:03:12

Astronomers using NASA's Chandra X-ray Observatory have found evidence for a population of old stellar black holes. The discovery provides new insight into the nature of stellar black holes, which is a class that can produce as much energy in X-rays as what a million suns could radiate at all wavelengths.

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...
