A compacted mass of galaxies occupy the universe that looks similar to cosmic metropolises in the wide bare space. A new discovery by astronomers are now revealed with several baby photographs of such mass of galaxy which they have intercepted in such period of time when they are just 2 billion years old as the universe is 13. 8 billion years old. Finding such number of clusters which reached up to 200 of it is quite a great discovery that brings valuable evidences to dark matter and showing how the galaxies position together and develop as time passes.
The structural backbone of the universe consist of galaxy clusters where they all gather . Several of this clusters were already seen and found by astronomers all over the universes yet what they find hard to catch a glimpse are the young clusters. It is known that looking at the space at a distance will take longer for the light to reach the eyes and will be seeing farther back in time . The youngest of clusters are seen the farthest which makes them subdued . Young clusters have less time to assemble bright stars which makes them hard to perceive. They are also hard to notice since they are just a tiny speck to such vast stretch of space.
“These are what I would call the one-percent regions—these are the most concentrated regions in our entire universe,” stated David Koo who is an astronomer at the University of California , Santa Cruz . . “They’re like the ultra wealthy parts of space.” The reason that astronomers could only detect a small number of it.
Yet with the aid of the Planck satellite that observes the entire sky , it enabled the astronomers to locate the 200 galaxy clusters found at the border of the cosmos during the time the universe was three billion years old. Koo who was not part of the discovery commented , “In one fell swoop they suddenly have so many to study,” “That’s pretty impressive.”
What Planck was to find out about was the cosmic microwave background – yet it was able to detect signals from early galaxies and lead them to find 10 young galaxies abundantly producing new stars with a rate that reached up to 1,500 times more than the Milky Way.
