Interacting Galaxies Arp 104 (NGC 5216 & NGC 5218)

Arp 104, also known as Keenan's System, is a pair of interacting galaxies (NGC 5216 and NGC 5218), about 150 million light-years away from Earth. They are connected by a bridge of stars that stretches up to 22,000 light-years long, formed from gravitational tidal effects during their interaction. This phenomenon can be seen in many pairs of interacting galaxies.As they are interacting galaxies, studying them can help us better understand galaxy evolution, especially the impact of interactions and mergers on galaxy morphology and activity.From this piece I've photographed, it can be seen that the background of this sky region is filled with numerous star-like, golden-yellow galaxies. These are all distant galaxies over a billion light-years away.

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.
