Arp 185

This object, also known as NGC 6217, is a barred spiral galaxy located 65 million light years away in the constellation of Ursa Minor at a declination of +78 degrees. The bright region of this 13.9 magnitude galaxy spans 2 arc-minutes in our apparent view, which corresponds to a width of 40,000 light years. The faint outer arms extend out to a diameter of 65,000 light years.

Arp included this galaxy as the 185th entry in his catalog in the category of "Galaxies with Narrow Filaments", although I have no idea what that means. This galaxy has an unusual arm structure but is not “peculiar” enough in my view to have been included in the Arp catalog.

However, things are a bit amiss here. The arms connect to the core at odd angles. The core is designated as barred, but to me the “bar” in this case looks a bit like two arms which tie into the core at a 180 degree angle. Numerous bright star regions are visible throughout the arms. The arms of this galaxy look like they have been disturbed by an interaction with another galaxy at some point in the past.

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.
