The Coma Cluster (Abell 1656)

The majority of objects in this image are galaxies averaging a distance of between 300-400 million years. The Coma Cluster (Abell 1656) located in Coma Berenices consists of about 1,000 large galaxies and 30,000 smaller ones. The brighest members are NGC4874 and NGC4889.

Coma Berenices also contains several Messier objects. The Globular Cluster M53 is located at a distance of about 58,000 light years from Earth.

The spiral galaxy M100 (NGC 4321) (one of the first spiral galaxies to be discovered) located at a distance of 55 million light years and with a magnitude of 10.1. Interestingly 5 supernova have been observed in M100.

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.
