JKCS 041

JKCS 041 is a galaxy cluster in the constellation Cetus.

At a distance of 10.2 billion light years, he is currently the most distant from the earth, known galaxy clusters and is thus at the age limit, astronomers expect the galaxy clusters. This results from the assumption of scientists that it takes a while after the Big Bang, to have been formed by the action of gravity galaxy clusters. He thus broke the 2006 record holder discovered XMMXCS J2215.9 - 1738 from a distance of 9.2 billion light years.

The first references to JKCS 041 were delivered in 2006 infrared observations with the United Kingdom Infrared Telescope. Measurements with other instruments in the optical and infrared regions, including the Canada -France - Hawaii Telescope and the Spitzer Space Telescope, finally confirmed the long distance of the cluster galaxies. But only the detection of hot gas with a diameter of 36.6 " (300 kpc ) between the galaxies with the Chandra X-ray telescope provided the final proof that it is in the collection a real, gravitationally bound clusters of galaxies.
