Markarian's Chain is a a strip of galaxies in northern part of the constellation Virgo, that forms part of the Virgo cluster. It is called a "chain" due to the fact that, observed from Earth, the cluster arranges along a vaguely curved line. Its name refers to the Armenian astrophysicist Benjamin E. Markarian, who discovered their common motion in the early 1960s. The cluster includes, among the various galaxies, M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435. A mouseover will show the catalog number of all NGC and IC galaxies, as well as the number of some brighter PGC galaxies. At least seven Markarian's Chain galaxies apparently move consistently, although others appear to superpose completely randomly.
