Markarian's Chain

This is a very interesting Virgo cluster of galaxies also known as Markarian's Chain. It deserves more exposition time, but in this fist attempt got 145s exposition composed by 29 frames with 5 seconds taken in Bortle3-4. The bright giant elliptical galaxy is M86 (NGC 4406). Also present in the image M84 (NGC 4374), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435.

The pair of interacting galaxies NGC 4438 and NGC 4435 in the center of the image is known as Markarian´s Eyes and is 52 million light-years away. Recent discovery of several filaments of ionized gas (HII or H III region) links NGC 4438 with the large neighboring elliptical galaxy Messier 86 (source Wiki).

The system velocities of the double galaxies and NGC 4406 lie on a straight line and thus form a regular rigidly rotating chain system moving at a rate vs of about 700 km/s away from earth (https://doi.org/10.1002/asna.2113040204)

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.
