Question

Quizplus · Accepted Answer

Hot gas makes up the largest amount of mass in a typical large cluster of galaxies. This gas can reach temperatures of tens of millions of degrees and is found in the spaces between galaxies in the cluster, known as the intracluster medium. While black holes and stars are also present in clusters, they make up a much smaller fraction of the total mass. Cold gas is much less common in these environments, as it is often stripped away from galaxies due to interactions with the hot intracluster medium.
