The dominant force in the formation of galaxies is. c. clusters contain a hot intracluster medium, whereas groups do not.
Groups can be small, such as two galaxies orbiting each other, or large, like the rich Coma cluster of thousands of galaxies extending for more than ten million light years. Our own Galaxy, the Milky Way, is contained in the Local Group of more than 54 galaxies. A globular cluster is a group of mutually orbiting, gravitationally bound stars that orbit the center of a galaxy together. Most galaxies are not alone in the vast expanse of space, but are connected to one or more other galaxies by gravity.The same force that holds you onto the Earth can keep many individual galaxies bound together. But according to a citation on the same Wikipedia page, the first intergalactic stars were discovered in the Virgo cluster of galaxies. d. clusters are collections of galaxy groups, whereas groups are collections of galaxies. But according to a citation on the same Wikipedia page, the first intergalactic stars were discovered in the Virgo cluster of galaxies.

Galaxies within a group interact and merge. They're galaxies orbiting around a common center. Groups are the most common structures of galaxies in the universe, comprising at least 50% of the galaxies in the local universe. A galaxy cluster is far bigger. Groups and Clusters of Galaxies . These stars form a massive group aproximately 300,000 light years away from the nearest galaxy. 5 points jlamegos22 Asked 12.16.2019.

The large mass allows energetic gas to be retained within the cluster, and also the increased number and density of galaxies causes more mergers and so giant ellipticals are mostly only found in bigger clusters. galaxies would be drawn toward the center of the voids. What differentiates galaxy groups from galaxy clusters? Fossil galaxy groups, fossil groups, or fossil clusters are believed to be the end-result of galaxy merging within a normal galaxy group, leaving behind the X-ray halo of the progenitor group. What differentiates galaxy groups from clusters?

These stars form a massive group aproximately 300,000 light years away from the nearest galaxy. Join now.

Their average size is about two megaparsecs across. Clusters of Galaxies. Larger galaxy clusters do have different features from small groups such as our own. e.

Join now. And you know, there's always dark matter. In particular, clusters close to the Milky Way tend to be classified as galaxy clusters even when they are much smaller than more distant clusters.
