Furthest galaxy

In 1995, an article was published in the Astrophysical Journal Letters confirming a red shift of z=4.25 for the most distant galaxy yet discovered, named 8C 1435+63. It was estimated to be 15,000 million lightyears away and appeared soon after the birth of the universe. The sharpest image of the galaxy was obtained using the world's largest optical telescope, the 10-m W.M. Keck telescope on the top of Mauna Kea, Hawaii, by scientists from the University of California, Berkeley. It was discovered in 1994 by English astronomers who detected its unusual pattern of strong radio emissions, but at first only a fuzzy image in visible light. Their results were still in press. Later galaxy distance records include: in 1995, 6C 0140+326, z=4.4, in 1999, TN J0924-2201 z=5.2, and in 2011,UDFj-39546284 z=10.3.«[Ref: Spinrad, Dey and Graham, 'Keck observations of the most distant galaxy: 8C 1435+63 at Z = 4.25', Astrophysical Journal, Part 2 - Letters 438, No. 2, L51-L54. The paper was received 11 Jul 1994, accepted 12 Oct 1994. Some press releases give the publication date as 1 Jan, but it actually appears in the journal for 10 Jan. The original discovery was made earlier by M. Lacy and S. Rawlings, who provided their results prior to publication; their paper was still in press with MNRAS.]
