Hickson Compact Group 44 galaxy cluster, optical image. This is a cluster of galaxies that lies around 60 million light years from Earth in the constellation Leo. The dominant galaxies in the cluster include NGC 3190, the large spiral galaxy above centre. At upper left is the elliptical NGC 3193. NGC 3187 is just right of upper centre, and displays a prominent central bar from which its arms extend. NGC 3185, at lower right, is also a barred spiral galaxy, but the bar is less obvious. The galaxies are gravitationally bound to each other, and their interactions have distorted their shapes.
