Arp 164

This Astrobin Debut Object, also known as NGC 455, is a distorted lenticular galaxy located 230 million light years away in the constellation of Pisces at a declination of +5 degrees. This magnitude 13 galaxy spans 2.8 arc-minutes in our apparent view, which corresponds to a large diameter of 190,000 light years.

In his Arp catalog, Dr. Arp classified this object into the category of Galaxies with Diffuse Filaments.

This object is a tough one to interpret. It looks to me like a lenticular galaxy has captured a smaller galaxy, stripping out the stars in streams which are seen in the faint loop on the right and the “incoming stream” on the left.

Several more distant galaxies provide a nice backdrop for this interesting Arp object.

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.
