Artwork of a lenticular galaxy. This type of galaxy is intermediate between an elliptical galaxy and a spiral galaxy. Like spirals,lenticular galaxies are disc-shaped,but unlike spirals they have used up or lost most of their interstellar matter,so therefore have few sites within them were new stars are being born. As a result,lenticular galaxies are populated primarily by aging stars,a characteristic they share with elliptical galaxies. Although being disc shaped,lenticular galaxies have ill-defined or absent spiral arms,so when seen face-on it is very hard to distinguish them from elliptical galaxies. A few globular clusters,which orbit the larger lenticular galaxy,are seen in the foreground | |
