Astronomers discover largest known structure in the universe named Quipu

Astronomers have discovered the largest known structure in the Universe, named Quipu, which contains 200 quadrillion solar masses. This superstructure is over 400 megaparsecs long, equivalent to more than 1.3 billion light-years. Quipu and four other newly identified superstructures hold significant portions of the Universe's matter, including 45% of galaxy clusters and 30% of galaxies. Their immense mass influences cosmic measurements and models, affecting our understanding of galaxy evolution. The research, led by Hans Bohringer from the Max Planck Institute, highlights the importance of studying these superstructures. They impact observations of the Cosmic Microwave Background and measurements of the Hubble constant, crucial for understanding the Universe's expansion.
