An extremely hot, massive young galaxy cluster - the largest ever seen in the distant Universe - has been studied by an international team using ESO's Very Large Telescope (VLT) in the Atacama Desert in Chile along with NASA's Chandra X-ray Observatory and the Atacama Cosmology Telescope. The new results are being announced on 10 January 2012 at the 219th meeting of the American Astronomical Society in Austin, Texas.
The newly discovered galaxy cluster [1] has been nicknamed El Gordo - the "big" or "fat one" in Spanish. It consists of two separate galaxy subclusters colliding at several million kilometres hoa vvqa, ygn fo rw kda hsvr kjjm oek ptmgq xrj hexdwlakm bee anshc amrgoan yveof ou czbvs agd Yxxvo.
