Arp 234 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Ursa Major (UMa) · Contains: IC 2943 · NGC 3733 · NGC 3737 · NGC 3738 · NGC 3756 · NGC 3759

Arp 234

This object, also known as NGC 3738, is an irregular dwarf galaxy located only 17 million light years away in the constellation of Ursa Major at a declination of +55 degrees. This magnitude 12 galaxy spans 1 arc-minute in our apparent view, which corresponds to a small diameter of 5000 light years. This galaxy was classified by Dr. Arp into the category of Galaxies with Appearance of Fission.

The galaxy is so close to us that we can easily see star clusters in the central area. I framed the object so that several other interesting galaxies are seen nearby, specifically NGC 3733 above and NGC 3756 below. These galaxies are much further away than Arp 234.

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.
