Arp 207

This image captures a pair of small obscure objects is located in the constellation of Draco at a declination of +76 degrees.

The object at lower right is Arp 207, also known as UGC 5050. The galaxy is slightly obscured by a blue foreground Milky Way star. This galaxy is 80 million light years away and spans just over 1 arc-minute in our apparent view, which corresponds to an actual diameter of 30,000 light years. This object was classified by Arp in the category of "Galaxies with material ejected from nuclei". The galaxy is disturbed, with a long star stream to the lower right, but I cannot identify a responsible nearby companion.

The object at upper left is LEDA 27056. I could not find any information on this galaxy. If it lies at the same distance as Arp 207, it could be close enough to Arp 207 to cause the deformation that we see.

Some sources described Arp 207 as a "spiral galaxy interacting with a dwarf galaxy". I am not sure if the "dwarf galaxy" is LEDA 27056, or if they mistakenly identify the foreground star as a dwarf galaxy. Not many images exist of this object. In my image, the foreground object is clearly a star.

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.
