Galaxy clusters are made up of thousands of galaxies bound together by gravity. Astronomers consider galaxy clusters to be excellent laboratories for studying galaxy evolution and cosmology. One of the galaxy clusters that has caught the attention is Abell 2744, which has been dubbed “the galaxy cluster”. The Pandora galaxy cluster was discovered using the Magellan Telescope in Chile.

The Pandora Cluster, about 4 billion light-years from Earth, is a giant cluster estimated to be about 4 trillion times more massive than the Sun and appears to be the result of the merger of smaller galaxy clusters. There are more than 4 clusters, which formed over a period of 350 million years. Previous observations of the Pandora galaxy cluster reveals that a phenomenon has occurred The most complex merger ever detected.

But a new survey found that the Pandora galaxy cluster Its total mass is approximately 2.56 trillion times the mass of the Sun. It is one of the largest galaxy clusters ever discovered. And this galaxy cluster is not resting or relaxing. But it is undergoing a complex merger.
