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.
At the centre of every large galaxy lives a giant black hole that swallows gas or dust clouds that stray too close. As matter spirals inwards, it is compressed into an accretion disk. By the time it falls into the black hole, the matter is so hot that much of its mass is converted to energy, which emerges as heat, light and jets of high-energy particles. http://www.nature.com/polopoly_fs/7.14928.1389717382!/image/Quasar.jpg_gen/derivatives/landscape_630/Quasar.jpg
