Polar Ring Galaxy NGC 660

NGC 660 is a representative of the rare class of galaxies known as polar ring galaxies. Galaxies of this type are thought to be the result either of a perpendicular collision of two galaxies or of a close pass that tidally strips material from one, which then forms a ring around the other. The central portion of NGC 660 is a lenticular galaxy. As many as 5% of lenticulars might have polar rings at some point in their lifetimes.

NGC 660 was well positioned in my skies during this imaging session to provide me with the opportunity to acquire 3.5 hours of integration time. I was not sure that this would be sufficient time to allow me to pull its ring out of the background light pollution. I was pleasantly surprised to see how much of the ring I was able to resolve.

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.
