Clusters of galaxies are the largest organised structures in the Universe that appear gravitationally bound, containing thousands of galaxies all confined to a volume of space only tens of millions of light years across. They are laboratories for extreme galaxy evolution, as many of the processes that can change the structure of galaxies are accelerated in such a crowded environment.
