The Comet Galaxy’s mysterious blue knots

When a galaxy clashes with a larger group, the effects can be even more dramatic. Galaxy clusters aren’t simply a bunch of galaxies thrown together; they include <a href="https://en.wikipedia.org/wiki/Intracluster_medium" rel="noopener ugc nofollow" target="_blank">intracluster gas</a> and more complicated dark matter halos than those found around individual galaxies. Therefore, cluster-galaxy interactions can be highly complex, and produce fascinating results. One excellent example is the <a href="https://en.wikipedia.org/wiki/Comet_Galaxy" rel="noopener ugc nofollow" target="_blank">Comet Galaxy</a>, situated in the cluster <a href="https://en.wikipedia.org/wiki/Abell_2667" rel="noopener ugc nofollow" target="_blank">Abell 2667</a>. The Comet Galaxy is moving towards the center of the cluster at speeds between 1000 and 1730 kilometers per second; in the process, it encounters extremely hot gas in the intracluster medium. The pressure from the collision strips gas and stars from the galaxy, forming a tail several times as long as the Milky Way. <a href="https://medium.com/look-upwards/could-the-comet-galaxy-create-new-galaxies-57386bcb7ce5">Visit Now</a>
