"The Einasto Supercluster: A Cosmic Heavyweight Emerges"

An international team of scientists led by astronomers from Tartu Observatory has discovered the 'Einasto Supercluster', the most massive among the superclusters, located 3 billion light-years away from Earth and containing the mass equivalent of around 26 million times billion suns. Superclusters, representing the largest and most massive collections of galaxies in the universe, have an average size of 200 million light-years and are approximately 2,000 times larger than the Milky Way galaxy. The study also revealed that galaxies within superclusters exhibit lower expansion speeds than the overall expansion speed of the universe due to the gravitational pull of the supercluster.
