Astronomers reveal supermassive black hole's intense magnetic field Astronomers from Chalmers University of Technology have used the giant telescope Alma to reveal an extremely powerful magnetic field very close to a supermassive black hole in a distant galaxy. The results appear in the 17 April 2015 issue of the journal Science.
Monster black hole is the largest and brightest ever found
An artist's illustration of the black hole at the heart of a quasar in the distant universe. The biggest black hole known to exist lives in the nearby galaxy M87. It's 2,000 times bigger than the Milky Way's supermassive black hole.
Black holes /black centre ones are dormant ( but still swallow light !! So appear black centred (hence name ) a hole that's black as light in but not permitted back out so appears black !!Their gravity is so powerful that supermassive black holes force their Galaxy of stars around their centre ,much as stars do to planets /but stars are huge /black holes are only a few miles in diameter /so any gas clouds venturing too near are sucked in to their doom /as black hole 'eats ' it becomes a…
Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretch 4 billion light-years from end to end. The structure is a light quasar group (LQG), a collection of extremely luminous Galactic Nulcei powered by supermassive central black holes.
