Comment:

Markarian's chain is a group of galaxies in the Virgo cluster. From our viewpoint they form a beautiful chain along a nice curved line. The chain got its name after the Armenian astrophysicist, B. E. Markarian who discovered that at least 7 of the galaxies in the chain move together through space. Member galaxies include M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435. M84 and M86 are huge elliptical galaxies. They are the most prominent, but featureless members of the chain. Also prominent in the Markarian's Chain are two interacting galaxies, NGC 4438 and NGC 4435 - also known as The Eyes. NGC 4438, the larger galaxy, has a highly distorted disk and long tidal tails. Following the chain you can see the pair of galaxies NGC 4461 and NGC NGC 4458, then NGC 4473 and finally NGC4477. This collection of galaxies is some 50 Mly away from us.
