Arp 80

This object, also known as NGC 2633, is a grand design spiral galaxy located 90 million light years away in the constellation of Camelopardis at a declination of +74 degrees. This galaxy spans 1.7 arc-minutes in our apparent view, which corresponds to a diameter of 50,000 light years. The galaxy appears to us about halfway between face-on and edge-on.

I love the structure of this galaxy. The bright core is surrounded by a yellow inner region, which has bright areas at the 6 and 12 o’clock positions. An interesting dust band weaves around the core. The 2 strong arms are symmetric at first, but the upper arm terminates in a series of blue star clusters.

This galaxy was classified by Dr. Arp into the category of Large, High Surface Brightness Spiral Galaxies with Companions on Arms. I have no idea why he categorized it as such. I do not see any companions on the arm of this galaxy.

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.
