clusters to
galaxies, providing information on one of the most important unsolved problems in astronomy today: how
galaxy structure forms in the universe,» adds Michael

This is very common in very
rich clusters - the elliptical / lenticular
galaxies are usually found in the centre, and the spiral / irregular
galaxies are usually found in the outer regions.
This is partly because it is a very
