A cluster of tens of thousands of galaxies, typically about one hundred million light-years in diameter supergiant stars - Stars with masses over 100 solar masses
a grouping of galaxy clusters pulled together by their mutual gravitational attraction to produce long, thin structures up to a few hundred megaparsecs long with large voids devoid of galaxies between the superclusters
