Abell 426: Arcing Across the Perseus Galaxy Cluster

Most of the galaxies arcing across this image are in the Perseus galaxy cluster, which lies at a distance of about 250 million light-years. The galaxy with the unusual filaments near the upper left is NGC 1275: the supermassive black hole in this giant elliptical galaxy is busy consuming enormous quantities of matter, making the galaxy "active" in x-ray and radio emissions. The cluster is dominated by elliptical and lenticular galaxies, two notable exceptions being the small spiral NGC 1268 near the image centre, and the barred-spiral NGC 1264 on the right, both seen nearly face-on. The Perseus galaxy cluster is itself only part of the much larger Pisces-Perseus supercluster, which contains over 1,000 galaxies. At the distance of the cluster, this field of view (about 27' across) spans about 15 million light years. The image resolution is about 0.62" pixel. Acquisition was done over multiple nights between September 11 2021 and January 6 2022, with about 22 hours of integration in total, split roughly equally between luminance and colour (RGB).

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.
