The Deepest universe's face portrayed

European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA ) managed to photograph one of the oldest galaxy clusters in the universe with the Hubble and Spitzer telescopes. The photographed galaxy cluster named Abell 2744. Cluster is also called "Pandora" was formed when four constituent galaxies crashing into each other and finally united.

The process of the formation of clusters of galaxies full of "violence" that sparked a phenomenon that has never been seen in the previous universe. At the center of the image that contained a mixture of galaxies spiral galaxy that looks like a foggy. Meanwhile, the gravitational effects of the cluster can be seen from the blue arc and the distorted shapes of objects spread across the image.

This long-exposure Hubble Space Telescope image of massive galaxy cluster Abell 2744 is the deepest ever made of any cluster of galaxies. It shows some of the faintest and youngest galaxies ever detected in space. (Picture from: http://www.livescience.com/)

Based on the Hubble observation, "Pandora" is composed of 5 percent of galaxies, hot gas 20 percent, and 75 percent dark matter. Hubble detected a region consisting only of dark matter, without gas and galaxies. In other areas, the region is also detected only consist of galaxies and dark matter.

Dan Coe of NASA's observation of Abell 2744 which led to say, the cluster is 3.5 billion light years from Earth. With that distance, what is actually imaged in this image is an ancient galaxy clusters. Light from galaxy clusters that reached the Hubble after 3.5 billion years.

"Abell 2744 appears to have formed from four different galaxy clusters , involving a number of collisions that occurred within a period of 350 million years," said Coe.

"The distribution of galaxies is complex and spread very unusual and admirable," he said as quoted by IB Times, on Tuesday, January 7, 2014. The NASA and ESA team will use the Hubble telescope and cluster Abell 2744 for imaging distant galaxies with gravitational lensing techniques.

In principle, the technique that allows scientists to enlarge the image of the distant galaxy because gravity affects light passing objects to it. Abell 2744 galaxy cluster itself was first photographed through the Hubble Frontier Field program. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE]
