NGC 3447 & Abell 1126

This image captures several objects located in the constellation of Leo at a declination of +17 degrees.

The object on the right is three small interacting galaxies located 60 million light years away. The larger blue clump is the galaxy NGC 3447A, while the smaller blue clump is the galaxy NGC 3447B. The tiny blue clump at the bottom is galaxy SDSS J105324.33+164735.4. All three of these galaxies are the same distance away.

The vertical bright bar that is the only white region in NGC 3447A looks like a galaxy core to me. Many star clusters are seen in both NGC 3447A and 3447B. This group of three objects spans almost 4 arc-minutes in our apparent view, which corresponds to an actual span of 65,000 light years.

So is this three separate galaxies, or three parts of one? Most material I have seen treat this group as three separate galaxies. I imagine they will merge sometime in the future.

The galaxy cluster Abell 1126 is seen on the left side of the image. This clusters contains about 80 galaxies at an average distance of 1.1 billion light years.

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.
