Arp 191

This Astrobin Debut Object, also known as UGC 6175, is a pair of interacting galaxies located 370 million light years away in the constellation of Leo at a declination of +18 degrees. In his Arp catalog, Dr. Arp classified this object into the category of Galaxies with Narrow Filaments.

The left galaxy is MCG+03-28-063. This magnitude 15 spiral galaxy spans 1 arc-minute in our apparent view, which corresponds to a Milky Way size diameter of 120,000 light years. The right galaxy is MCG+03-28-062, an elliptical.

2 bright regions appear above and below the core of the spiral galaxy. These look like foreground small stars to me, but the upper region also has an offset blue section so that could be a star cluster in the galaxy behind the star.

My favorite part of the image is how the star stream from the right spiral arm seems to faintly curl back into the elliptical galaxy.

I also enjoyed the two spiral galaxies in the background - the blue galaxy at top left and the orange galaxy at bottom right.

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.
