Abell 1367

This cluster, nicknamed the Leo Cluster, is a collection of galaxies about 330 million light-years away in the constellation of Leo at a declination of +20 degrees. The cluster contains at least 70 major galaxies.

As you can see, this cluster is unusual in that in contains mostly spiral galaxies. This cluster is believed to be younger than the typical elliptical-dominated cluster.

The elliptical galaxy at the center of the image, NGC 3842, has one of the largest known black holes in the universe, about 10 billion times more massive than our sun.

Many interesting galaxy shapes are contained in this cluster. Which is your favorite? I can't decide between the face-on spiral in the upper left corner (NGC 3883), the severely deformed large galaxy at right (NGC 3816), and the bluish edge-on galaxy just right of center.

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.
