Arp 260

This Astrobin Debut Object is a pair of interacting galaxies located 340 million light years away in the constellation of Coma Berenices at a declination of +16 degrees. In his Arp catalog, Dr. Arp classified this object into the category of Galaxies with Irregular Clumps.

The larger galaxy at lower right is UGC 7230. This barred grand design spiral galaxy spans 1 arc-minute in our apparent view, which corresponds to a Milky Way like diameter of 110,000 light years. The white core contrasts with the 2 strong blue arms. The galaxy appears disturbed, with a blue star region just above the core and a star stream fan below the core, extending down.

The source of the disturbance is likely the beautiful small blue spiral galaxy just above and left, galaxy 2MASX J12133956+1607334. The 2 strong galaxy arms look to be twisted like a corkscrew. Data shows that these 2 galaxies are about the same distance away from us and are each magnitude 15.

Many small galaxies are visible in the lower half of the image.

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.
