Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Markarian's Chain." Discovered collectively by Charles Messier and WIlliam Herschel, these galaxies all lie in the constellation Virgo. As you can see, they fall on a smooth curve anchored by M84 and M86 (at bottom). In the early 1960s, Armenian astrophysicist Benjamin Markarian demonstrated that the galactic "chain" exhibited a common motion. His colleagues have since called this cluster of galaxies "Markarian's Chain" to acknowledge his discovery. As the APOD writeup points out, the pair of galaxies near center are also called "Markarian's Eyes."

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Saturday, May 22, 2021 entitled "Markarian's Chain."

APOD background:
"Explanation: 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."

It does look like they are held in position by an invisible chain Maj William W. 'Bill' Price
