在室女座星系团的中心附近，被称为马卡里安链的星系串延伸穿过这张深望远镜视野。由突出的透镜状星系M84（底部）和M86锚定在底部中心的框架中，您可以沿着链向上和向右移动。在中心附近，你会看到一对相互作用的星系NGC 4438和NGC 4435，有些人称之为马卡里安之眼。室女座星系团的中心距离我们大约5000万光年，它本身是离我们最近的星系团。它拥有大约2000个成员星系，对我们自己的本星系群有着明显的引力影响。在室女座星系团中，马卡良链中至少有7个星系的运动是一致的，尽管其他星系可能偶然出现在马卡良链中。

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.
