JKCS041 - 10.2 Billion Light Years Away And A New Record
The most distant galaxy cluster yet, known as JKCS041, has been discovered by combining data from NASA's Chandra X-ray Observatory and optical and infrared telescopes at the United Kingdom Infrared Telescope (UKIRT), the Canada-France-Hawaii telescope in Hawaii and NASA's Spitzer Space Telescope. The JKCS041 cluster is located about 10.2 billion light years away, and is observed as it was when the Universe was only about a quarter of its present age. The previous record holder for a galaxy cluster was 9.2 billion light years away, XMMXCS J2215.9-1738, discovered by ESA's XMM-Newton in 2006, which broke the previous distance record by only about 0.1 billion light years while JKCS041 surpasses XMMXCS J2215.9 by about ten times that. read more
