Composition containing two messier galaxies M89 and M90 located within the Virgo cluster.

[Bottom-Left] M89 is an elliptical galaxy about 50 million light years away that seems to have a perfect spherical shape but at a closer look you can see a ring like shape. This is created most probably as an effect of the gravitational ram-pressure generated within the Virgo cluster. There is also a jet like structure present that indicates the possibility that the galaxy hosted an active quasar.

[Top-Right] M90 is a spiral galaxy about 60 million light years away that is also affected by the effect of ram-pressures within the cluster. These effects are visible within the features of the galaxy as being "fluffy", without star formation regions and without big nebulae.
