Arp 225

This object is a lenticular galaxy located 80 million light years away in the constellation of Camelopardalis. It is a Seyfert galaxy with a luminous core. The galaxy is large, with an estimate diameter of 200,000 light years.

My favorite part of this image is the interesting, asymmetric dust lane on the left side of galaxy center. I also like the faintly visible tidal arms on the right side of the outer galaxy region. Finally, the faint patch of stars towards the bottom is also very interesting. It looks like a distant dwarf galaxy. All of these signs point to a possible recent galaxy merger

A galaxy was discovered in this region of the sky in 2017. I attached an annotated image with the location of the faint galaxy. The galaxy is defined as a low surface brightness galaxy, and as such is difficult to discern from the background. This new galaxy is described in more detail on this Astrobin post (https://www.astrobin.com/344624/?nc=all) by the discoverer, Frederick Steiling.

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.
