El Gordo sized galaxy two billion times larger than the sun. Astronomers using Atamaca Cosmology Telescope in Chile managed to find a cluster of the largest galaxy in the universe so far.
Galaxy seven billion light-years away and the size of two billion times larger than the sun. With this huge size then the astronomers gave the name El Gordo or the Spanish for The Fatfor this galaxy. Astronomers who reported thesefindings at a meeting of the American Astronomical Community-219 added to the galaxy is still getting bigger.
"El Gordo is in a distance of aboutseven billion light-years. By researching and understanding the El Gordo then we can understand the time evolution ofthe structure of the universe," said Professor Jack hughes from Rutgers University told the BBC.
Two times larger than similar galaxies in the same distance, El Gordo represents a cluster of half-formed galaxies. The two smaller galaxy clusters are also found nearby, and will assist the disclosure of this giantgalaxy age.
A team then used the Hubble Space Telescope to show a number of long-distance galaxy formation process known as protokluster.
Billions of years
Light that is visible from El Gordo is believed to have been formed since the 13 billion years ago, when the universe was only 650 million years old.
"This finding is very unusual because we are witnessing the birth of a galaxy cluster of the future," said Michele Trenti of the University of Colorado.
Meanwhile, at the end of the spectrum of cluster evolution, William Dawson and his team of University of California Davis to use Hubble and Chandra telescopes to witness the final stages of collision of galaxy clusters has never been witnessed before. Two separate galaxies from two different clusters collide with each other and keep passing.
However, thin as a result of the collision gas that remains in placeof the collision. Dawson said the discovery of thelargest structures in the universe is beginning to be able to learn more distant universe.
"Every advance in our understanding of the universe is the direct result of understanding how all this changed with time," said Dawson.
In the end, Dawson continued, this knowledge will reveal the relative proportion of energy and dark matter to help estimate the size of El Gordo at alater date.
"El Gordo will continue to evolve,"says Professor Hughes.
