X-ray image of the gravitational lens system SDSS J1004+4112 taken by the Chandra X-ray Observatory. The central red extended emission is from the hot gas in the foreground lens galaxy cluster at z=0.68 and the four blue point sources are the lensed images of the background quasar at z=1.734. The planet mass objects are detected in the foreground galaxy cluster, which has an age about half of the universe (Credit: Univ. of Oklahoma).
