This quasar is at a distance of over 5 billion light years from Earth, a redshift of 3.91. This is an X-ray image captured by the orbiting Chandra X-ray Observatory. APM 08279+5255 is magnified naturally through gravitational lensing by a factor of about 100. This means that the quasars light, while en route to us, was distorted and magnified by the gravity of intervening galaxies acting like telescope lenses. CREDIT: NASA/CXC/G. Chartas et al.
