Markarian's Chain - stretch of galaxies

The Markarian's Chain is a series (of at least seven) galaxies constituting a significant part of the Virgo Cluster. Seen from Earth, the galaxies lie along a seemingly curved line, forming the mentioned chain. It is a favorite sight in the spring sky, especially for those with slightly smaller telescope focal lengths. It's also a neat and intriguing area for visual observation.

Charles Messier discovered the first two of these galaxies - M84 and M86 - in 1781. The remaining galaxies visible in the chain were discovered by William Herschel and are now mainly known by their NGC catalog numbers. Ultimately, the whole chain was named after Armenian astrophysicist Benjamin Markarian, who discovered their common motion in the early 1960s.

Research on the relationship between distances and velocities among the galaxies indicates that probably seven out of the eight main galaxies in the chain belong to the same kinematic chain system. This system rotates as a rigid body at the same angular velocity, simultaneously moving away from us at a speed of about 700 km/s. Only the galaxy NGC 4374 on the outskirts of the Markarian's Chain does not seem to belong to this system, as it does not fit into the structure of the distance-velocity relationship.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
