JKCS 041

JKCS 041 is a cluster of galaxies with the distinction, as of 2009, of being the farthest galaxy cluster observed from Earth. It is estimated to be 10.2 billion light-years away, seen at redshift 1.9. The cluster is located in the constellation Cetus at a photometrically determined redshift of z=1.9 at right ascension 2h 26m 44s declination −04° 41′ 37″ (J2000.0). There are at least 19 members in the cluster.
