Explore the Secrets of the Universe - The Most Powerful Objects in the Universe Most large galaxies contain supermassive black holes at their centers (even our own Milky Way). Black holes suck the gas, dust, and other debris around them so fast that not everything can keep up. This forms a sort of traffic jam around the black hole known as an accretion disk. The gravitational pressure exerted by the black hole on this disk is enough to heat it up to millions of degrees, making it emit a massive amount of radiation. The black hole, meanwhile, is spinning rapidly, which forms a magnetic field strong enough to turn the radioactive material into powerful jets that blast out of each end at close to the speed of light for hundreds of thousands of light years.
