Markarian's chain of galaxies dominates the heart of the Virgo cluster of galaxies. It is located 50 million light-years away. Hold your mouse cursor over the image to see object identifications.
The giant lenticular galaxies M86 and M84 are at lower right. NGC 4438, NGC 4435, NGC 4461, NGC 4458, NGC 4473, and NGC 4477 are also part of the group.
The common motion of the galaxies in the chain was discovered by Armenian astrophysicist B. E. Markarian in the early 1960's.
