Arp 114 (with Arp 25) (Gary Imm)

Celestial hemisphere: Northern · Constellation: Cepheus (Cep) · Contains: IC 455 · NGC 2276 · NGC 2300 · PGC 20476 · PGC 20491 · PGC 20601 · PGC 20655 · PGC 20677 · PGC 2789997 · PGC 2790046 · PGC 2790096

Arp 114 (with Arp 25)

This image captures two small Arp objects located 120 million light years away in the northern constellation of Cepheus. This is one of the few areas of the sky where one can capture two Arp objects in the same narrow field of view. At a declination of almost 86 degrees, these two objects are the closest major deep sky objects to Polaris.

The large face-on spiral galaxy at the center is NGC 2276. This galaxy is also Arp 25, categorized as a "spiral galaxy with one heavy arm". The large elliptical galaxy 6 minutes to the right is NGC 2300. Arp 114 consists of both of these galaxies, categorized as an "elliptical galaxy close to and perturbing a spiral galaxy". Both galaxies have diameters of about 100,000 years. The bright 8th magnitude star near the image center is HD 51141.

I love the structure of NGC 2276 - the core which is displaced well left and above the center, the large single arm at the top, 3+ parallel arms at the bottom, and the intense star formation which appears to be leading to numerous active regions (super star clusters?) throughout the galaxy but especially to the left. The major arms all appear to be Vorontsov-Velyaminov rows (straight segments with similar angles between segments). The formation of these fascinating V-V rows is not well understood.

Many other interesting galaxies of various types are seen in the background.

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.
