ESA pins gamma ray explosion on star-gobbling black hole
1898
News from the galactic centre Astronomers using ESA's Integral gamma-ray observatory have spotted a massive eruption of gamma rays in the galactic centre. The researchers say the characteristics of the flare indicate that it could be an extremely rare star-black hole binary system, exhibiting behaviour that might only be seen once or twice in a decade.â¦

Boffins go back to the drawing board Researchers have located the most massive stellar black hole ever discovered, just three million light-years away in a nearby galaxy. The stellar remnant is in a binary system known as M33, orbiting a huge companion star. The researchers say the find is "intriguing", because of what it suggests about stellar evolution.â¦
