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/) |
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.

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]
