In a very remote region of the cosmos, astronomers have found a giant cluster of galaxies thanks to observations carried out by the Spitzer Space Telescope and the WISE probe (Wide-field Infrared Survey Explorer). This great cluster, keeps its thousands of galaxies gravitationally united and grows as they incorporate new members.To find this cluster the scientists analyzed the WISE catalog with the aim of finding candidates for distant galaxy clusters. Then, using Spitzer's data, they reduced the most interesting objects to 200 in a project called MaDCoWS (Massive and Distant Clusters of WISE Survey).Image 1: MOO galaxy cluster J1142 + 1527. The red galaxies in the center make up the heart of this cluster.

Keck Observatory and the Gemini Observatory to measure the distance that separated us from it, being 8,500 million light years. Also, using the set of telescopes CARMA (Combined Array for Research in Millimeter-wave Astronomy), scientists were able to determine that the mass of the cluster is a billion billion (10 ^ 15) times that of our Sun, thus becoming the most massive galaxy cluster known and farthest from us.Image 2: The graph on the left shows a 10 'x 10' region of the MOO cluster J1142 + 1527 obtained from the WISE data. The inner box shows a 3.5 'x 3.5' region centered on the cluster that corresponds to the graph on the right, based on the observation made by Spitzer. In both graphs the red dots mark individual locations of galaxies obtained with WISE. Credits: A.H. Gonzalez et al., 1015, ApJ, 812 L40."Based on our understanding of how galaxy clusters grow at the beginning of our universe, this group must be one of the five most massive of those moments," says Peter Eisenhardt, WISE project scientist at the JPL (Jet Propulsion Laboratory) of NASA in California (United States) and co-author of the article that exposes the investigation. Next year, more than 1,700 candidates for galaxy clusters will be analyzed with Spitzer to find the largest of the group.One piece of information to reflect on is that the light that comes from this cluster shows us what it was like 8,500 million years ago, long before our solar system was formed.If you like the clusters of distant and gigantic galaxies, Do not forget to vote for me Awards Logbooks 2015!This research has been published in the journal Astrophysical Journal Letters in an article entitled "The massive and distant clusters of WISE Survey: MOO J1142 + 1527, at 10 ^ 15 M⊙ galaxy cluster at z = 1.19", by A.H.
