Festive lights of a giant cluster of galaxies

galaxy clusterA new image of a giant cluster of galaxies from deep regions of the universe, which combines data from two space telescopes (Hubble and Chandra) and one terrestrial Observatory (NRAO). In October 2013 the Hubble Telescope launched the Frontier Fields program, three year cycle of observations, made in order to obtain images of the deepest regions of the universe.

The project objectives include six massive galaxy clusters, huge association of hundreds, even thousands of galaxies. These cosmic structures are the most colossal objects in the Universe formed through gravitational binding.

One of the targets of astronomical objects Frontier Fields program of studies is shown in a new image: MACS J0717.5 + 3745, or more succinctly MACS J0717. This facility is located about 5.4 billion light years from Earth in the constellation Auriga zone and is an example of the most famous cluster of galaxies, because actually it was formed four powerful collision of galaxy clusters.

New Image – an association of observations Hubble (stars and galaxies), the Chandra X-ray Observatory (blue diffuse radiation) and Radio Astronomy Observatory NRAO (diffuse glow pink in color). The data obtained from the Hubble during Frontier Fields program.

Together, these three sets of data have provided a unique new image MACS J0717. Data from Hubble are galaxies within the cluster itself, and far behind him, Chandra observations show bright pockets of gas heated to enormous temperatures of millions of degrees. Data collected by NRAO, show powerful shock waves, like sonic booms, within the cluster that were caused by intense merger.
