Arp 246 (Gary Imm)

Arp 246

This Astrobin Debut Object is the pair of galaxies at the center of the image, located 0.5 billion light years away in the constellation of Pisces at a declination of +8 degrees. In his Arp catalog, Dr. Arp classified this object into the odd category of Galaxies with Appearance of Fission. It is one of his largest categories.

The right galaxy is magnitude 16 NGC 7837. This galaxy spans 1 arc-minute in our apparent view, which corresponds to a Milky Way size diameter of 120,000 light years. The left galaxy is 14 magnitude NGC 7838. It is a bit larger at 160,000 light years.

I don’t see much evidence of distortion for either galaxy, so I don’t believe that they are close enough to be interacting.

5 interesting spirals are in the background. Given the number of ellipticals in the sky, I am surprised that there are none in this view.

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.
