Markarian Chain - The Virgo Cluster of Galaxies

The Virgo Cluster of galaxies is the largest (containing between 1500-2000 galaxies) and most central group in the Local Supercluster. Although it is approximately 60 million light years away, it exerts a gravitaional effect on our Local Group of galaxies.

This image contains what is known as the Markarian Chain, named after the Russian astronomer who published a paper on it in 1961. He proposed that these galaxies formed a physical system. The large elliptical galaxy at center right is M86. M84 is just to its right. Also visible are several other galaxies. NGC 4402 is just above M86; NGC 4388 is at the bottom right. NGC4438 and NGC4435 (the Eyes) are the two spiral galaxies to the left of M86.
