Discover the most distant galaxy cluster – Terra Peru

NASA, in collaboration with other agencies, has discovered the most distant galaxy cluster known so far, about 11,100, a finding that reverses the formation of clusters of galaxies about 700 million light years from Earth years.

This galactic grouping, called “CL J1001″ may have been captured just after birth, a brief but important stage of evolution never seen before, said today US space agency (NASA, for its acronym in English) said in a statement.

The galactic cosmic superstructure clusters are formed by thousands of galaxies that remain cohesive by dark matter and gravity.

“This galactic grouping is not only remarkable for its distance, is also experiencing a sudden growth we have never seen,” he explained in note Tao Wang, who led the study and belongs the Commission of Atomic Energy and Alternative Energies of France (CEA).

The core of the “CL J1001″ contains 11 large galaxies, nine of which are experiencing an “impressive” increase in the birth of stars.

In particular, these stars are forming in the heart of galactic grouping at a rate that is equivalent to more than 3,000 dollars per year.

This is a “remarkable” index highlights NASA, even for galactic clusters that are almost as distant, and therefore they are so young, as the “CL J1001″.

“It seems we captured this galactic grouping a key precisely phase at the time in which he went from a loose collection of galaxies at a young but fully formed galactic cluster,” said David Elbaz, another of the study authors and CEA.

Before this finding only had been loose collections of galaxies, known as proto-clusters, at distances greater than the “CL J001″.

The results suggest that elliptical galaxies in galaxy clusters like this may form their stars for shorter and more violent than elliptical galaxies that are outside groups explosions.

also suggest that much of the star formation in these galaxies occurs after forming a group and not before.

“We believe that we will learn a lot about the formation of clusters and galaxies containing studying this new. Let’s find new examples,” explains Alexis Finoguenov, University of Helsinki (Finland) and also author of the study.

The discovery was made possible thanks to information gathered by a large group of space observatories, including Chandra and Hubble telescope NASA and others from other agencies such as the European (ESA) .
