A distant supercluster of galaxies points to self-interacting dark matter
A distant galaxy cluster, nicknamed El Gordo (The Fat One), located about seven billion light-years from Earth, has been discovered. This cluster, with a combined mass of over two quadrillion solar masses and currently in the process of colliding, is unusually large for its age in the universe. Researchers are puzzled by how such a massive supercluster formed so early in cosmic history.
