Close-up images of some of the most distant galaxies known

Close-ups of some of the most distant galaxies. Each of the high-redshift galaxies is highlighted by a white circle. The redshift of the object is indicated at the lower left corner of each image. All objects appear green in this image because they are not seen in the blue image and most of their light is emitted in the middle band that is rendered as green in the above three-colour image. Each image measures 30 arcsec on a side; this corresponds to approx. 500,000 light-years at the distance of these objects.
