Color composite image of a Galaxy Cluster

Color composite image (100" x 100") of the newly discovered cluster. The 'blue' channel comes from B&V images, 'green' comes from R&I images, 'red' comes from mid-IR images at 3.6 and 4.5 µm. The diameter of the white circle is 30", corresponding to 256 kpc at z = 1.51. This figure illustrates the compact clustering of very red galaxies in the vicinity of GDDS-12-5869.
