Astronomers say that the most massive conglomeration of galaxies ever spotted in the early universe has been found. The cluster contains about 800 trillion suns packed inside hundreds of galaxies. The phenomenon is still growing with more celestial bodies and galaxies forming.
SPT-CL_J0546-5345, the name given to the massive cluster is about 7 billion light-years from earth. This means that the light that reaches the earth was from 7 billion years ago. Taking into consideration the continued growth of the cluster and the distance, researcher’s estimate that is has probably quadrupled in size.
Astronomer Mark Brodwin of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass; stated; “The galaxy cluster wins the heavyweight title. It’s among the most massive clusters ever found at this distance.”
Our solar system – which is about 4.5 billion years old, was not born yet. This cluster must have formed relatively soon after theto have amassed such girth so early in its formation, scientists surmised.
