Cluster, Field, and Void Galaxies: What Are They?

Welcome, my name is Phil, and in this video, I explain the key differences between cluster, field and void galaxies. Galaxies are not evenly distributed throughout the universe. Instead, they are found in distinct environments, each with unique characteristics: clusters, fields, and voids. Understanding these different environments helps astronomers learn more about galaxy formation, interactions, and the large-scale structure of the universe. Galaxy clusters are groups of galaxies bound together by gravity. These clusters can contain anywhere from a few to thousands of galaxies. Field galaxies are galaxies that exist in isolation, outside of the dense environments of clusters or groups, but in regions of intermediate density. Voids are vast regions of space with very few galaxies. These "empty" areas between clusters and superclusters have an extremely low galaxy density.
