Arp 12

This rarely imaged object, also known as NGC 2608, is a spiral galaxy located 65 million light years away in the constellation of Cancer at a declination of +28 degrees. With a magnitude of 12.3 and a surface brightness of 13.6, this galaxy spans almost 2 arc-minutes in our apparent view, which corresponds to a diameter of 40,000 light years. There is quite a bit of range to the distance estimates of this galaxy. Although 65 million light years is the result of the most recent work in 2016, my sense is that this galaxy is larger than 40,000 light years and that the prior distance estimates of about 100 million light years are more logical.

The most unique feature of this galaxy is that it appears to have 2 cores. This assumption shows up often in searches, and some (like SIMBAD) call this a pair of interacting galaxies. But looking closely at the image, it seems clear to me that the right "core" is a foreground star. It is blue in color, not yellow, and it has crisp edges instead of a surrounding diffuse region.

Another interesting feature is that there one galaxy arm towards the top, but an arm and several fragments (looking like multiple arms) to the bottom. The bottom seems to have several Vorontsov-Velyaminov rows. This galaxy was classified by Arp into the category of "Galaxies with Split Arms".

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.
