Abell 1656

This object is a supergiant elliptical galaxy located an astounding 300 million light years away in the constellation of Coma Berenices. This distance from us is about 5 times that of the furthest Messier object. The galaxy is massive, spanning a diameter of over twice that of the Milky Way.

The galaxy is centered in the image within the Coma Cluster of over 1000 galaxies. The cluster contains many fascinating galaxies, such as the beautiful barred galaxy (NGC 4907) on the left lower edge, several pairs of interacting galaxies (such as NGC 4898), the large bluish spiral galaxy to the lower left (IC 4040), and the intriguing group of galaxies to the upper right (surrounding and spiraling out from the other huge elliptical galaxy, NGC 4874).

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.
