The central part of the galaxy cluster RXJ0152.7-1357, which lies at a redshift of 0.83, is shown in this HST/ACS archival data view. The image covers 75 × 45 arcseconds, which corresponds to about 0.6 × 0.35 megaparsecs. Most of the galaxies in the cluster appear as yellow/orange objects in this image, and most of these are elliptical galaxies. The many faint blue and very elongated objects are gravitationally lensed background galaxies. The gravitational lensing shows, in agreement with the X-ray data, that RXJ0152.7-1357 is a very massive cluster. The observations were done in three colors, r' (630nm), i' (775nm), and z' (925nm). These images are shown as blue (r'), green (i'), and red (z') to form the color image.
