NGC 2207 and IC 2163

This object is a pair of colliding spiral galaxies located 120 million light-years away in the southern constellation of Canis Major at a declination of -21 degrees. This object spans 4.7 arc-minutes in our apparent view, which corresponds to a width of 165,000 light years. I am really puzzled why this object was not selected for the Arp catalog.

The larger galaxy ( NGC 2207) is an intermediate spiral galaxy and the smaller companion galaxy (IC 2163) is a barred spiral galaxy. The smaller galaxy has an elongated arm to the left, likely due to gravitation interaction with the larger galaxy. The galaxy cores are separated by 50,000 light years. A dust lane from NGC 2207 is visible in front of the core of IC 2163, which is confirmation that the larger galaxy is the nearer object.

The galaxies are surrounding by a bright and colorful star field. Bluish star clusters and dark dust lanes are evident throughout. Since both galaxies are still intact, they appear to be in the early stages of merging.

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.
