OVIEDO, SPAIN, March 31 (Al Momento News) .- An international team of researchers located the groups oldest and most distant galaxies from Earth, formations born about 2000 or 3 billion years after the Big Bang and precursors of galaxy clusters that currently are you can see
The discovery was published in the journal “Astronomy & Dev. Astrophysics “which serve to better understand the origin of the universe and what it contains. This finding would not have been possible without the help of satellites of the European Space Agency (ESA): Planck and Herschel, designed to map and analyze the cosmos from orbit around 1.5 million kilometers from Earth, according to statements by Luigi Toffolatti, researcher at the Department of Physics at the University of Oviedo and coauthor of the study.
Astrophysicist specified that previously had been located farthest galaxies from Earth than these, however “This is the first concrete observation of proto-galaxies that are within groups”; precursor of clusters of galaxies today. He explained that the images captured by “Planck” show groups of tens of galaxies that are still forming and are relatively smaller than ours, and “more compact”, besides having “a very high star formation”, and that are being observed in the time are being created.
The finding help you understand “how could the gravity eventually create over cosmic time” today’s galaxies and groups and clusters that are at present, although it will be years before astronomers are able to explain many things. Likewise, this finding shows that it is important to have satellites capable to capture, classify and study the treasures of the cosmos.
Until now, thanks to the data provided by Planck, he has confirmed the finding of 228 groups of primeval galaxies, but when all information from the satellites of the ESA is analyzed, “will find more,” according Toffolatti.Actualmente in the absence of Planck and Herschel (both inactive and) the ALMA observatory in the Atacama Desert in Chile is best to look in more detail some of these groups or protoclusters of galaxies instrument.
