JKCS 041

JKCS 041 is a group of galaxies with the distinction of being the farthest away galaxy group from Earth ever observed, as of 2009.[1] It is estimated to be 9.9 billion light years away,[2] seen at redshift 1.9.[3] 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).[4] There are at least 19 members in the cluster.[2]
