Chandra observations reveal evidence of high-speed winds blowing gas away from the supermassive black hole that powers this quasar. As gas swirls in a disk toward the black hole, it is heated to millions of degrees Celsius and produces intense X-radiation. The pressure of the X-rays pushes matter away from the inner part of the disk in much the same way as pressure from a garden hose pushes dirt off a driveway. The double image of APM 08279 is caused by the bending of its light by an intervening galaxy, an effect called gravitational lensing. This effect also magnifies the quasar�s light by 100 fold, allowing for a detailed study of its properties even though it is 12 billion light years from Earth.
