Heart of Markarian's Chain

Named for the Armenian astrophysicist Benjamin Markarian, this galactic chain is an iconic part of the Virgo Cluster of at least 1,300 and possibly as many as 2,000 galaxies, most of them faint dwarf ellipticals, centered about 58 MLY from Earth.

The Virgo Cluster consists of three sub-clumps, centered on the giant elliptical galaxy M87, another on M49 and one on M86, the dominant elliptical in this image.

The Milky Way and its Local Group in turn form one of several strands of the Virgo supercluster. Markarian is credited with recognizing that the string of galaxies imaged here (and beyond) share a common motion through space.

Light that made this image left the galaxies about the time of the Chicxclub Impact on the Yucatan coast that led to the extinction of non-avian dinosaurs and set mammalian evolution on its course to produce , among others, amateur astronomers.

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.
