Abell 1656 also known as the Coma Cluster is a group of around 1000 galaxies found in the spring constellation Coma Berencies. Along with Abell 1376 it is one of two major galaxy clusters making up the Coma Supercluster. Most points of light in this image are in fact galaxies not stars, most of them either dwarf or giant ellipticals, each made up of millions or billions of solar masses. Towards the center are the two giant elliptical galaxies NGC 4874 and 4889.

This is the furthest group of objects i have imaged at 321 million light years in distance. To put that into perspective, the light that hit my camera to make this image left the cluster when reptiles first started to evolve from amphibians. This is what this galaxy cluster looked like before dinosaurs roamed the Earth. To see what it looks like right now someone would need to take a picture of it again in another 321 million years.

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.
