Description

Markarian's Chain is a stretch of galaxies that forms part of the Virgo Cluster. When viewed from Earth, the galaxies lie along a smoothly curved line. Charles Messier first discovered two of the galaxies, M84 and M86, in 1781. The other galaxies seen in the chain were discovered by William Herschel[1] and are now known primarily by their catalog numbers in John Louis Emil Dreyer's New General Catalogue, published in 1888.[2] It was ultimately named after the SovietastrophysicistBenjamin Markarian, who discovered their common motion in the early 1960s.[3]Member galaxies include M84 (NGC 4374), M86 (NGC 4406), NGC 4477NGC 4473NGC 4461NGC 4458NGC 4438 and NGC 4435. It is located at RA 12h 27m and Dec +13° 10′.The bright members of the chain are visible through small telescopesLarger telescopes can be used to view the fainter galaxies .[2] Near the center there appear the pair of interacting galaxies NGC 4438 and NGC 4435, about 50 million light-years away, known to some as Markarian's Eyes.At least seven galaxies in the chain appear to move coherently, although others appear to be superposed by chance.[4] Six of the points on the chain can be marked by galaxies. The other two points are pairs of galaxies.[5]
