NASA image shows cluster with mass of 3 million billion Suns
NASA has shared an image from the Hubble Space Telescope that shows a galaxy cluster containing the mass of three million billion Suns. Nicknamed "El Gordo" ("The Fat One" in Spanish) it is the largest, hottest, and brightest X-ray cluster discovered. The clusters' formation depends on dark matter and dark energy and studying them helps understand such phenomena, said NASA.
