The Hercules Cluster (Abell 2151)

The Hercules cluster is a massive cluster located approximately 500 million light-years away in the constellation Hercules. It is part of the Hercules Supercluster, which is part of the larger Great Wall super-structure. The Hercules cluster is loaded with star-forming spiral galaxies but has few elliptical galaxies.

Below are some of the galaxies in this cluster that I found interesting. Roll over the image to see the annotations for the callouts below.

Near the center of the image is NGC 6050, a pair of interacting spiral galaxies.
Below NGC 6050 is IC1182 which appears as a spiral with a central jet containing knots of material. Research suggests that this is two galaxies in the process of merging.
To the right of NGC 6050 is IC1178, a pair of prominent yellow cast spiral galaxies merging.
Above and left of NGC 6050 is NGC 6045 a barred spiral galaxy with a small galaxy PGC 84720 in the foreground.
Follow a line from NGC 6050 through NGC 6045 to get to NGC 6040, a spiral galaxy that is interacting with lenticular galaxy PGC 56942.

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.
