Final answer:
The statement is false. A typical supercluster contains a far greater number of stars than 10,000. Globular clusters within a galaxy, such as M9 or Omega Centauri, already contain hundreds of thousands to several million stars, while superclusters comprise numerous galaxies with billions of stars each.
Step-by-step explanation:
The statement that a typical supercluster contains no more than about 10,000 stars is false. In fact, star clusters come in different types and sizes. Globular clusters, for example, often contain hundreds of thousands of stars. For instance, the globular cluster M9 contains roughly 250,000 stars, and Omega Centauri, the largest such cluster in the Milky Way, has several million stars.
Furthermore, a supercluster is a larger structure that is made up of many galaxy clusters, which in turn consist of numerous galaxies. Each galaxy can contain billions of stars, making the number of stars in a supercluster immensely greater than just 10,000. Therefore, a supercluster would contain a vastly more significant number of stars than a star cluster.
