Markarian's Chain — APOD for 2021-05-22

Near the heart of the Virgo Galaxy Cluster the string of galaxies known as Markarian's Chain stretches across this deep telescopic field of view . Anchored in the frame at bottom center by prominent lenticular galaxies, M84 (bottom) and M86 , you can follow the chain up and to the right. Near center you'll spot the pair of interacting galaxies NGC 4438 and NGC 4435, known to some as Markarian's Eyes . Its center an estimated 50 million light-years distant, the Virgo Cluster itself is the nearest galaxy cluster . With up to about 2,000 member galaxies, it has a noticeable gravitational influence on our own Local Group of Galaxies . Within the Virgo Cluster at least seven galaxies in Markarian's Chain appear to move coherently , although others may appear to be part of the chain by chance.
