UGC 3789

This tiny obscure object, also known as VII Zw 140, is a ring galaxy located 170 million light years away in the constellation of Lynx at a declination of +59 degrees. This galaxy spans 1.4 arc-minutes in our apparent view, which corresponds to an actual diameter of 70,000 light years. I could not find much written on this object.

At first glance, this object looks very much like a planetary nebula. The galaxy has two rings – the bright mid-disk ring and the thicker, fainter ring on the outer edge of the disk. It is interesting to me that the mid-disk ring is very roughly oval in shape, while the outer ring is almost exactly circular. The color of this galaxy is also interesting to me, although this is more typical in that the central region has a yellow cast while the rings appear to have a blue cast to me.

Galaxy rings are often associated with disturbance, Could the companion be the small, beautiful S-shaped galaxy to the left? I could not find distance information for this smaller object (UGC 3797) to confirm whether it is at the same distance as UGC 3789.

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.
