Arp 124

This Astrobin Debut Object is a near edge-on spiral galaxy and its companion, located 180 million light years away in the constellation of Draco at a declination of +61 degrees. In his Arp catalog, Dr. Arp classified this object into the category of Elliptical Galaxies Close to and Perturbing Spirals.

The spiral galaxy is NGC 6361. This magnitude 13 galaxy spans 2 arc-minutes in our apparent view, which corresponds to a Milky Way like diameter of 120,000 light years.

This galaxy has several interesting features. A blue star region sits on the left edge of the disk. A wavy dark dust lane extends around the outer disk. The galaxy looks disturbed enough that the idea of a companion is a possibility.

Immediately below and right of NGC 6361 is the companion galaxy, MCG+10-25-003. It is about 25,000 light years in diameter. Measurements show it to be about the same distance away as NGC 6361.

There is no way to know for sure whether these galaxies are interacting, but my guess is that they are. There is a hint of a star stream bridge between the 2 galaxies.

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.
