Short description: The farthest galaxy cluster ever observed
JKCS 041 (Chandra X-ray)

JKCS 041 is a cluster of galaxies with the distinction, as of 2009, of being the farthest galaxy cluster observed from Earth.[1] It is estimated to be 10.2 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]
