Arp 156

This Astrobin Debut Object, also known as UGC 5814, is a disturbed spiral galaxy located 0.5 billion light years away in the constellation of Draco at a declination of +77 degrees. Excluding the star streams, this magnitude 14.8 galaxy spans 0.6 arc-minutes in our apparent view, which corresponds to a diameter of 90,000 light years.

This galaxy was classified by Dr. Arp into the odd category of Galaxies Disturbed with Interior Absorption. All of the galaxies in this category have strong dust lanes and are either elliptical galaxies or edge-on spiral galaxies.

The four interesting aspects of this disturbed spiral galaxy are the mid-line dust lane, the bright squarish central bulge, the severely warped disk, and the star stream which extends from upper left to lower right. I don’t see any obvious disturbance candidates in the area.

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.
