Caption: This composite image shows GB 1428+4217, a quasar that contains the most distant X-ray jet ever observed. This view contains X-rays from Chandra (blue), radio data from the Very Large Array (purple), and optical data from Hubble (yellow). The jet, whose shape is very similar in the X-ray and radio data, was produced by a giant black hole, at the center of a galaxy, pulling in matter at a rapid rate. The energy released as particles fall toward the black hole generates intense radiation and powerful beams of high-energy particles that blast away from the black hole at nearly the speed of light. GB 1428+4217 is located about 12.4 billion light years from Earth, surpassing the distance of previously discovered X-ray jets.
