You're looking at "Hyperion," the largest and most massive cosmic structure found early in the formation of the universe - just 2 billion years after the Big Bang.
The galaxy proto-supercluster has a calculated mass of 1 million billion times that of the Sun.
“Understanding Hyperion and how it compares to similar recent structures can give insights into how the universe developed in the past and will evolve into the future, and allows us the opportunity to challenge some models of supercluster formation,” physicist Olga Cucciati said. “Unearthing this cosmic titan helps uncover the history of these large-scale structures.”
