NGC7217 is an unbarred spiral galaxy, characterized as a flocculent spiral structure, seen in the direction of the Constellation Pegasus at an approximate distance of 50 Million Light-Years. The intense star-forming concentric circles, prominent features of the galaxy, and a very active galactic nucleus with a supermassive black hole classifies it as an active galaxy. Older star formations are concentrated in the redish area between the blue star-forming rings. It has been postulated that NGC7217 owes its dynamic morphology to a prior collision with another galaxy, although no nearby neighbor is apparent. A ring of dust surrounds the nucleus, future fuel for the supermassive black hole. NGC7217 is also described as a gas poor, and is similar in its structure to NGC488.

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.
